    Lifted Rx300 With Big Tires

    still trying to get in touch with that Aus. suspension company. No reply on ebay so I messaged and called them today. Too bad they are on the other side of the Earth. I really don't feel like having to call them in the middle of the night or have them call me back and wake me up.. oh well. the price of progress. Gotta get Lexter ready for the next outing in a month or so.

    Those running boards look pretty nice on there. I almost had a set of them but the guy didn't want to dig them out of storage for me. I could really use more of a rocker guard/sliders setup anyways.The exhaust comes below the body and body channel a good bit and I have smashed it a few times and it catches if you hit anything like a ditch. This last time out I curbed it right in the middle of the muffler and in the same trip when I hydro locked the engine the Y pipe came loose. 3rd time is a charm, I finally safety wired the nuts and bolts. Those strut mount spacers would be by far the easiest lift you could do! I couldn't find mount spacers anywhere when I was doing mine and doing it with the spring perch spacers helped stiffen the stock springs just a little bit. If I can get those heavy duty springs and still have a problem with my tires hitting the fenders when I hit something really really hard I might look for spacers again. For just a little more money than those I could probably have my machinist make some out of billet.

    I contacted these guys https://www.ebay.com/itm/LEXUS-RX-330-350-MCU38R-MY05-4X4-F-R-30mm-RAISED-COIL-SPRINGS/160720012716?hash=item256ba8c5ac:g:gL4AAOSwOgdYnVnc that Brickwall linked to to see if they could make a 40-50mm lift for my 00' 300. I am not sure what the difference is between the two and don't have the time to really check and see of the 330-350 springs would work for me. I will keep you posted.

    Welcome to the club. I like it! Yeah, please share a little more. I would like to see what you attached it to as well. Maybe a couple pics of the front on level ground so we can get an idea of your clearances. I would love a winch. I was thinking of incorporating a reciever hitch into whatever i come up with in the front for protection so i could use one of those small reciever winches front or rear. I need to find more garage and play time somewhere.

    Yeah, I haven't replaced the factory steel tube bumper yet thinking I would have to grab what i wanted anyway. Nothing as serious as your bumper more of maybe something like on a light baja. Just heavy enough for real protection if i catch a ditch. Those springs are a nice find! I am probably going to order a set and have them swapped when i replace my busted front shock. Second one i have busted but they are way cheaper than coil over. The rx project is currently in a now in maintenance only slot. I will post if i get those taken care of. birthday trip with it in a couple months.

    No. I don't think you will ever find anything bolt on for what we are doing. There was some stuff available when these were new but still nothing as strong as needed. I haven't had much time to play with my RX lately. She did finally get a new battery after my last hydrolock adventure though but that had been going bad for at least a year or two. I should have gone for the sealed battery but just couldn't justify the price of an Optima type. I have another trip coming up and still need to fix a busted shock and a bad rattle under the dash. I guess i finally knocked something loose and am really impressed how much abuse it has taken before something came loose. My latest thought for a skid plate is to go get one from a Tacoma or something like that and just fabricate the mounts. It might not be the prettiest that way but function over form. I don't think the lower of my AC condenser can take anymore physical damage. It is a miracle it doesn't have a hole the way it looks. It has been beaten so badly from running through all the brush and tall grass. I always thought brush guards were for looks. Now i really need one. Maybe Brickwall could fab us up a couple?

    That is awesome, good work. I for sure need a bumper, I don't have the factory metal bumper or foam behind the plastic anymore. It got smashed and I had to repair the passenger side bumper mount after skidding through a turn into a tree. I was thinking one that would just bolt to the factory mounts through holes cut in the plastic. Nothing fancy just something I could attach a nice skid plate to. I have already gone through a couple sets of the plastic fender and engine guard pieces. I found these today: http://dgrcoilovers.com/product/lexus-rx300-4wd-0003-dgr-high-performance-coilovers/ Not sure if they are available and I have some questions for the guys but man they are expensive. Thinking the "Track Version" should be beefy enough if I can get some input from them on the spring rates and if there is any +height adjustment and if they come with the camber plates or not. I found a site "BodyKits" that has all kinds of stuff for the RX but apparently making them look more like a race SUV is much more popular than off roading with them, that is where I found the DGR from Australia made in HK. Found some other funky Gecko ones on ebay for cheaper.

    It's looking awesome! I could use a lightweight bumper and skid plate for sure. Radiator keeps taking a beating when running through the tall grass/weeds. Is that a bumper for another application you are trying to adapt or was it custom for the RX? I now see there are full sets of strut spacer lifts on Ebay from Russia if anyone is looking for a really easy lift. Tallest I see is 40mm~1.5" which is what I have with my spring spacer lift. I would rather use something like that with stiffer springs but the spring lift does double duty. If only a set of custom coil overs with a camber plate didn't cost more than my RX. I have to drive about 2 hrs to the management area we play in and the way the camber is set for the trail can wear you out driving it on the road.

    Ok i am going to preface this with if do not have an RX or have anything useful to contribute please respectfully keep your comments to yourself. We already know our RX vehicles were not intended to be hardcore rigs. Ok, So i managed to hydro lock my rx this weekend. Luckily an easy recovery and didn't damage the engine. Pulled the plugs, shook out my k&n and Lexter fired right back up. I did lose an exhaust gasket and had 3 inches of water in the floor but hey, i will take it as collateral damage or at least the cost of the adventure and story. So this is getting to the point of obsurd but i am looking for thoughts on something like a snorkel or at least a better way to protect the intake from aspirating water. I really don't want to cut a hole in the side or have anything permanent and rediculous looking as an RX with a snorkel. I don't need it to run underwater or anything like that just a way of getting a little better protection than the low intake behind the headlight. The water i was going through was 2 maybe 2 and a half feet deep, not even over my tires. It is a well established rock and gravel road that occasionally floods with fresh clean swamp water. We were not going fast at all but plowed up enough water in the front of the hood it made it to the air box installe and drowned. If anyone has put any thought into a solution for the RX i would like to hear what you came up with.

    Well Done with the coil overs! Mind sharing which ones you used (brand, part numbers etc..) and what if anything else you needed to do it. We should start compiling all the info everyone has used for their setup so we can something known to work from for the different years but right now it is just what each individual has kind of figured out for themselves. Did the rear struts change from 03-04? I am running the 245/70R-16 BF Goodrich KO2 on my 2000 rx300 with a ~2.5" spring lift and 2" wheel spacers with no rubbing. You will probably need to go with a different tire or get different wheels if you want to use the KO(2) or your existing wheels. TireRack.com only shows the K02 available for 15" and 16" wheels, the T/A KO for 17" and then the Rugged Trail T/A for 16,17 and 18. The Rugged Trail definitely does not have the same aggressive look or side tread as the K02 or K0 if that is why we both like them but they would be much better on the road but you could probably use your 18" wheels with them.

    Looks Good. Don't use more spacer than you have to otherwise your turn radius will suffer. Mine was bad before and is horrible now. Doesn't matter when you can slide the vehicle but on the rode it sucks when you need to turn.

    I hear you, I don't think the wide track would look right on the newer bodies. I did mine for sliding around corners on gravel and dirt so the wide stance really helps plant it. I always felt like the 300 was a little tipsy on the road with the factory setup but it did great in 6" of snow even with the highway tires, never had to deal with a lot of snow, let alone ice.

    Now you can see how the wheel spacers will give you the extra tire clearance at the perch. I want to say with the 2" spacers on mine it puts the edge of the tire somewhere right at the outside edge of the perch. I could have fit larger tires but went smaller and should probably go to smaller spacers like 1" to 1.5" to fix the edge of my tire hitting the top of the fender when bottoming out.

    The world of lifting RX vehicles is still pretty small so there aren't exactly any definitive guides but like any other strutted vehicle the same limitations in tire/wheel fitment would apply. The first limitation on my 300 was the rear spring perches because they are squattier than the fronts. Side clearance of the spring perch will limit how tall and wide of a tire you can fit without modification or for a certain offset/spacer. The next limitation for me was rubbing when turned full clock, not acceptable to me and I was able to fit mine with no rubbing. The taller and wider the tire the turning clearance is greatly reduced, its geometry but you can figure it out with a straight edge. Clock the wheels and take a straight edge across the inside sidewalls to the nearest obstruction and you can measure how much taller of a tire will fit without rubbing but leave some cushion. The closest point of the tire should be at the horizontal axis of the tire but make sure you look at fender clearances as well. Just take your time and measure everything until you are absolutely sure your fitment is what you want. You could also likely take it to a custom shop and they should be able to measure or use a jig to tell you what you can and can't fit. I would not recommend bringing the tire tread up past the bottom of the spring perch. If you do and you do not have ample clearances you can easily slash your sidewalls. If you are sticking with stock suspension the steering changes shouldn't be as drastic but just be ready for it to handle differently. I have not had to trim anything for mine and do not have anything rub except when I have 300-400 extra pounds in it and the suspension takes a really hard hit, mostly the rear where the outside tread just catches the lip of the fender. I need a little more travel or slightly stiffer springs in the rear. I think I am also running a larger wheel spacer than necessary (2"). Same thing for the front but don't hit the fender lip unless it is a really really hard suspension hit and I am turning. There is enough travel and clearance in the front if I am going straight over that really hard hit. I do not rub on the inside of the tire when turning but it is the outside front of the tire that hits the fender liner. That is only because it was a cheap aftermarket liner I was in a hurry to get in there to get some protection for my trans cooler before a trip. I had to cut the vents into the plastic and they puckered out into the wheel well so the tire catches them. I need to reinstall it so it fits correctly and likely make a little aluminum plate/grill for the vent slots so that doesn't happen. ***Edit- Brickwall says you have springs and shocks on the rear of yours and not a strut so that makes it a lot easier. You are then pretty much limited by the strut and turning clearance of the front then,

    Welcome to the unofficial lifted RX Club! That is an AWESOME RX! I would say this is a good place to post but we probably could start a new thread for all lifted RX. I would have preferred to use strut spacers but couldn't find any at the time, can you share a little more about the strut spacers you used and where you found them? I still need a little bit more lift or slightly harder springs especially in the rear and always wondered if there was an easy swap with something like a highlander or 4runner. I always wanted to go shopping at a pull-a-part just to see what I could make work but honestly I don't think I have the back for that sort of work anymore. Can you elaborate on what you found when you were looking or struts/springs that would work? It would be great to start building up how the travel/springs/heights compare. I think I have blew my right front strut and I think my wheels are just way to damn heavy for the stock struts. The 245/70R16 KO2s I have are 44lbs each and the next step down, the 235/70R16 are 36lbs! 8lbs is a lot so I am glad i didn't go with even bigger tires that would fit because the next sizes up are 48 and 50lbs each. I haven't played with my 300 much lately but I think a set of 1" strut lifts or one step back down in tire size is what I need to do next. I honestly haven't played with it much since I got a new toy (15' RC350 Fsport in Super Mica Blue) and Lexter now just stays hooked up to my boat and still does an excellent job with that at least once a week.
