Thanks for the reply. In talking with addco and research on other forums on this car the ride quality on normal roads is not changed and only comes into play on corners obviously. Addco also stated the bar was tested in conjunction with the stock front swaybar setup from the factory. It will most likely be my only suspension mod other than maintenence as the roads in the state of Massachusetts can be brutal after the winter plows ruin them and makes potholes etc.
What have you done to your LS400 ?? I am a Lexus noob but have worked on cars abit over the years.
Thanks
My LS400 is as stock as you can get right now - premium maintanace has only been done to it so far. but it is ready for some replacement parts especially in the suspension dept - Powertrain is as optimal as it will get for now with new fluids, timing belt, pulleys, plugs, plugwires and filters.
after inspecting all components in the suspension all bushings are dry, cracked and way "out of spec" shape so im positive that is contributing to my "boat" like feel. The shocks may be fine but i am opting for more stiffer Bilstein shock absorbers. thought heavily on the Muffler delete but also I love the quiet suprise essence the car has now - they don't notice me untill I pass by them - wouldnt want to alert them with a Throaty V8 sound. lol even though I love to hear my throttle body opening up with rushing air.
Sounds to me your doing things the right way, making sure everything is up to snuff before adding anything.
I went to my buddies shop today and we unclamped heated and removed the rear mufflers. They can be reinstalled if I want,,but I really like the sound! They're exiting before the rear axle now but it is quiet still but a nice mild rumble. Close the windows and you dont hear it unless you really stomp on it. I already made an appointment for making the pipes to the rear of the car as I like it that much. Not loud at all. You should try it for a day or two and if you don't like it clamp them back on. I was amazed the bolts for the clamps weren't seized with the winter salt up here but no problem! Yours should be cake!!!
never hurts to try anything once, and they are remarkably easy to remove and that is a reflection on how these cars are designed - very user friendly to the amatuer mechanics.
