I have just installed the L-tune suspension on my gs and havent heard a thing yet all I have to say about it is I LIKE!!!!!!!!!!!!!

 

Congrats biggie - tell us about your car (color, year, wheels, any other mods)...

Did you do the ECU? STB, or anything else? In the future?

 

After I installed the L-tuned springs and shocks, I can hear a rattle/clicking sound from the right front. I took it back to the mechanic, and they had verified their installation did not cause the noise. I sent the front shock set back to Steve@Carson, and he promptly replaced them with a new set. After I install the new set, no more noise. So if you can verify the installation is not causing the problem, then it's probably the parts.

 

Mine is more a popping sound in the R.front (2nd L-Tuned) and the same in the R.rear with more of a clunk.
I'll keep replacing until I get tired and then will have to go with a different product or have Lexus install until they get it perfect.

 

You can't go wrong with Bilstein Sport Shock with life-time warranty. Consider the best quality of shock in the market today.

 

I got a 99GS400 black on black with carbon fiber interior, 2 12"pioneer premier subs, rmm air intake, rmm front tower brace, L-tuned suspension both springs and shocks, blue neon ground effect lights under the whole car,18X8.5 Giovanna rio's with dunlop sp9000 245/45, red callipers on my brakes, and polarg m6 bulbs on the parking lights (makes them look blue the closest ones to the HID color) and soon to come NOS!!!!!!!! and I'm working with a company about a turbo for the GS400 if suscesful it would gain outputs to about 570hp

 

About your Polarg parking lights. Right now, i have PIAA's and they do not match the HID's. Is it worth it to get the Polargs, cause i believe that I will never get anything to match. Also, where can i get them
thanks

 

Your car sounds great.

How did you get red calipers, just paint 'em? If so, what paint?
