LexDiamondLS400

so i found the D.I.Y> link with how to wire the top portion of the brake lights to come on with the bottom....

But im still trying to find some info/help on the rear spoiler light replacement...

any help would be appreciated!

i have '99 gs 300 and i notice that when i press the brakes the full tail light doesnt light up anymore, meaning only the bottom lights up and not the top. all bulbs are fine and show red when the lights are on...

i read a while back that there was a mod to have all the lights light up, but previously mine did that on its own, so i was curious as to why it stopped working and what the mod was to get this back to how it was?!

also i have a stock rear wing and half of the bulbs are out on that as well and was curious were to find a replacement or how to change the bulbs if that was possible?!

Thanks in advance!!

Yeah, I have a similar problem with my 1999 GS3. It seems that my transmission is "slipping" when I slow down to almost stop then accelerate again. Its like it hesitates before it takes off again instead of a smooth acceleration. I talked to the dealer and they told me it was the computer getting used to my driving habits. What? Anyway, it seems like they have no idea what it is and no one else seems to know either that's why I'm trying to get into a GS4 but I don't know now if it has the same/similar problem. Sometime it goes away if I use the "power mode" button but I don't wanna drive around with that on all the time.

I had a similar problem when I purchased my GS. I had probs with hesitation when accelerating from 1st to 2nd gear as if the transmission was slipping, I reset the ecu and it temporalilly fixed it. Then one day the vsc and traction control lights both came on and I lost all power when pressing the gas pedal competely to floor. Took it the dealer the next day had them check the car out and run a diagnostics. They said the tps was fine and went ahead and flushed the throttle, they aslo cleaned the air mass flow thingy out LOL. Final thought I took the car home reset the ecu one last time drove the !Removed! out the car to let it adjust to my driving patterns, I put about 20 straight miles on the car after he reset, end result no probs for the last 4 months car drives like a dream and accelerates like new. I've had no probs with vsc/traction lights coming on nor probs with lack of power or acceleration.

I hope this information is helpful and useful, cuz I was pretty annoyed by those problems abd alittle upset lexus had no idea what was wrong. There was a post here a while back referring to this topic which is where I got the idea about cleaning the mass air flow and flushing the throttle. I actually recommended that to lexus and they agreeed since my car was still under warranty. So thankx Lexus Forums. The search button does wonders!!!

so I went ahead and took ur advice and contacted need4speed. I told them I was referred by u and want some info on 20's and tire size and ofset. I explained that I wanted an aggressive VIP look with the wheels flush, didnt want them to tuck. They reccommended 20x8.5 F 20x10 R 245/35/20 ofset +35 for the front and 275/30/20 ofset +43 for the rear. They said it would be perfectly flush and if I lowered the car depending on how much would determinehow much to roll the rear fenders and modify fronts if needed. So thanks again for ur help it was highly appreciated!

I have a '99 gs300 and the dealer told me that the doors lock when u hit a certain speed, but unfortunately that option isnt available on my model...which seems odd to me becuz it was in the list of features and options on the cpu the service manager had, but for some reason wouldnt set to the on position...pretty lame...atleast it unlocks when i put the car in park lol....

That *BLEEP* is HOTT, thanks for all the help and info, i will post some pics within 2weeks once i get the rims and tires and everything else...Thanks again!!! Oh yea what % tint u got?! is the front window slightly tinted too?! Those lexus brake covers are hott too where did u get them?!

Sounds good thanks!!! So u have 19's on ur gs?! u got any other pics?! side view?!

265s will not rub, you might even be lucky that 275s dont rub either. doesnt matter that should be the least of your worries. worry about how you might have trouble aligningm worry about how your tires are gonna wear out quicker, worry about how your comfort is gonna be gone, worry about how youre not going to want to peal out cause each tires cost 200 bucks, worry about how you're gonna feel the difference on your cars accelaration/fuel consumption....If you dont really 100 percent dont want to roll your fenders 265s will do. although rolling fenders with the machine is imposible to tell by any bystander so why not? machine costs around 200 dollars but local stores like tirerack and goodyear tires carry them and charge around 40 bucks for ur rear (u dont need the front). although i do not recomment you get it done by them because its a chain of stores and run by managers employing morons to do their work so they dont care if they screw up and lose a customer but if u go to a private owned motorsports then they'll care about a single customer and should do a clean job. Only and ONLY with machine is where your fenders being rolled will not be noticable. Id say you have to roll your fenders even if u lower the car on springs cause it will bounce especially on the freeway and will hit those 275s.

FRONT: going with 235s in the front makes the tire less wide and decreases the lenght/reach it has to touch the fender. 235s shouldnt rub in the front.

Bottom line: 235s with 265s is a better idea for 20s. Get 245/275 if you're going with 19s although you may still want to roll your fenders. Need4Speed personally owns a couple of these vehicles and should give you the best advice. Heres a picture i took in front of their warehouse in december to show you they personally own 2 gs'. I should have parked my car in the middle too....it would have been the nicest one, well after the m5 :)

Thanks for the comment on my car. I currently have the coilovers raised up just a bit cause i couldnt get in my own driveway.

ok so what abou the offset?! are the recommendations made from tirerack acurate?! they stated 20x8.5 245/30/20 ofset=35mm and 20x10 275/30/20 ofset=45mm. Also whats the name of the tool that rolls the fenders so i can purchase it if need be...Are u saying the reason i need to roll the fenders is in order to lower the car how i please?! BTW ur car is HOTT i lov the rims, u got a real sporty look! What % tint do u have?! thats a pretty clean lex right there! Oh and last what if i went with 235/30/20 in the front and 265/30/20 in the rear, would that make it possible to avoid cutting/rolling fenders?! thanks for all your help its been great, im definately trying to go for the look you have on ur car just not that much of a drop, i would ruin my car on these DC roads LOL....thanks again

REAR: In order to go 275s in the rear you need to have your fenders rolled. Now remember to roll your fenders, not bend in your fenders. Do not hammer, tap, hit, heat up and bend, or simply put a baseball bat in between and drive back and forth.....you will mess it up. If you want a pro job and no one notice your fenders have been rolled then you go with a special took thats made for rolling. Your rim comes off, tool gets clipped on and fenders gets rolled with no dents or paint chippings. This way no one is able to tell its been rolled. Height of tire will not matter, you may drop it and will have alot of free space in the back. dont worry about the height. So 275/30/20 = no problem. Picture of my car below has 275s in the rear on 19s with coilovers to show you the drop its able to get. So the height doesnt matter.

FRONT: 245/35/20 in the front with your drop should experiance rubbing on the front inner fender cover while taking turns. What will happen is eventually your cover will get worn out and create a hole. You have to option of cutting that part out or remove the entire cover. You also have the option of going with 245/30/20 in the front where it shouldnt rub but you may experience your speedometer to be off about 3 miles.

Thats why its recommended you stick with 19s on these vehicles although upto 22s have been installed before.

For additional information my buddies at Need4Speed would love to help you out. You may contact them toll free 1888.714.7467

ok that link gives good info on tire size but doesnt really help with the off set...anyone with 20's please help! Im tryna get some rims asap cuz the summer is here!

thanks for that site but honestly i dont understand it for !Removed! lol....i aint good with tires i'd rather see a pic of someones car and ask what settings they have lol...thanks again, anyone else have info on the offset for 20's?!

can any one please tell me the best offset for 20x8.5 front and 20x10 rear on a 1999 gs300?! Ive search the forums and everyone who has these settings had to roll or cut there fenders...i want a clean look, very flush without cutting or rolling the fenders unless absoulutely neccessary. Any help would be greatly appreciated. When i went to tirerack.com to check out some rims there off set was = 35mm for the front with 245/30/20 and 45mm for the rear with 275/30/20...i also read somewhere that i should get 275/30/20 for the rear and 245/35/20 for the front to even out the diameter, is this true?! thanks in adavance for any help!!! Oh and i plan on dropping the car about 1inch to 1inch 1/2 in front and rear depened on the wheel space...

Yes I too had to change 3 out of 4 door locks on my 1999 Gs300...it was all convered under warranty so it was cool, but its def somthing that is possible...My only prob is how weak the alarm key is...i changed the battery but the range for it is horrible, I have to be no furhter than 5 feet from the car...that sucks!

3k is a steal congrats on the new purchase! But how much u drop $$$ atthe body shop?! What typeof engine probs uhave?!

OK here are some pics of the car. I just tooks today, and seems like the engine is pretty much fine just the body damage on the right side as well as frame damage. Let me if anyone is interested. thanks.

Joe

I have 1990 lexus ls400 with about 250k, that was in great running condition. I was recently blind sided by this lady and my baby has sustained frame damage. Theres is damage to the right front bumper and fender as well as headlight and corner light. There is damage to the back right door and back right fender as well. The way I see it is it will cost too much to fix so im considering this car totalled. The car has alot of new parts and alot of good parts still. If anyone is interested in the car as is for parts please let me know, or if u want to fix the car please let me know. Serious inquiries only, i am willing to let the car go for cheap, but i will not be responsible for the shipping of the car. I live in MD and will give further information, as well as pics of the car a.s.a.p. My email is Joekilla3@hotmail.com for serious bidders only. The car has a brandnew paint job as well and i have pics of the car in my garage of it when i first purchased the car if u want to see how she looked before the accident. I am not considering selling individual parts at this time but my consider it in the future if the car doesnt sell. Thankyou for time and interest if u have any in my offer. God Bless.

The visor on my lexus has completely broken, before it just hung alittle but now the clip that holds the visor in place has broken/cracked( clip inside the roof the holds the right side/rod part of visor not little clip on right/drivers side). The only thing holding the visor up is the wires for the vanity light in the mirror. Please help if u know where to get a new clip and how to install or with any suggestions on how to fix this problem. Thanks alot for any info you can provide.

If I'm reading my diagram correctly, there's a white wire with a blue stripe that provides up to 20A to the radio, subwoofer and antenna. 

There's also a gray wire providing a 7.5A source to the radio only - I think this is the remote... (marked ACC in the diagram)

Not sure what you're looking for in regards to the ignition wire.  It thought the remote signaled when the car was on.

←

Do you know which wire is for the antenna?

Just use a harness but remove all the unused pins.

Are u looking for an original or afermarket. I have 1990 and i just removed my subwoofer and i dont plan on using anymore or placing another sub in that location. I am willing to give it to you if u pay for shipping to your home. Contact me via email if your interested. joekilla3@hotmail.com
