Just had some Tein CS coilovers installed on my 99 GS300. It is absolutely beautiful, black on black with a slight tint, dropped JJJUUUSSSTTTT over the fender wheels.....I'm telling ya, sexy as can be. The problem is with my L-tuned 18' Salinas (offset), Bridgestone Poles Position 960AS, I have this HUGE roaring noise on the highway, mostly when I'm turning. I just had the barrings replaced 1,000 miles ago.

Any suggestions?

power steering going out?

Does it sound like metal grinding?

Checked the power steering at the speed shop I go to. They see nothing wrong. Mind you, the speep shop works on my 06' Z so they are less than savvy when it comes to a luxury car like the Lexus.

Good question, it actually prompted me to go downstairs to check. And yes, they are all mounted properly.

might just be the tires. Does it get louder with speed? What type of tires are you running?

Are you saying you had the wheels on before the CS and did not have this noise?

Yes sir, had the Bridgestone's on before the coilovers and had no problems. As a matter of fact, I reall enjoyed the ride. The reason for the coilovers was that I could never get the rear end down enough with shock/spring combinations.

I'm wondering, has anyone else had noise issues with the Tein vs. maybe the HKS or other coilover set-ups.

check the tire pressure.

Tire pressure 28.5 all around

Is the tire rubbing the inner plastic under the fender? Give a visual check.
Raise the car a little more to see what happen.
Did you aligned the front wheels?
Does the steering keep straight in the highway?
Analize....

Let's see....checked the plastic under the fender, it's clear. The wheels aren't far enough out to worry about rolling. I raised the car and nothing. Alignment was done when the coil overs were installed, however, I do have a slight pull to the right when on the highway.

Has anyone heard the same noise issue with TEIN CS coil overs?

Of the people I know with the CS-T, no one complained about noise.

28.5psi also seems a little low. The Salinas offsets should be fine without rolling. I had the same wheels when I had my Flex.

What are the tire specs?

I had a similar problem. Roll down your window...

1. Take an Off Ramp exit a little faster...

2. Listen if the Roar is from the rear...if turning right on the off ramp...you will hear it from the drivers side rear fender well...

3. If it is then the offset on your rims is too high...your tire is scraping the plastic/rubbery portion of the fender well

4. You might have to get a lower profile or less wide tire..esp with the sweet drop.
