Hi there Lexus SC owners. New to the CL here looking to get great advices, mostly regarding suspension.

I have a 93 Lexus SC300 and being that it's 20 years old, the car takes alot of impact from the road. The car is basically bone stock exception of the both Front Suspension has been replaced with Supra Twin Turbo Front Shocks and Spring (For slightly lower drop). Other than that, the car is bone stock and drives very well. What bothers me is that it's taking alot of impact from the road. The Supra Twin Turbo Front Shocks and Springs were replaced no more than 4 months ago so I"m assuming they are fine.

Anyhow, at this point, I would like to get advices on how to make car take less impact from the road of everyday driving.

I was thinking about replacing all the rubber oem bushings from the Front to the Rear completely but wasn't sure if this should help significantly.

I am very mechanic incline, ASE Certified, I've done almost a dozen of SC300 Lower Control/Upper Control arm bushing replacement along with 100+ engine and transmission rebuilding and swaps.

All the work would be done by myself, I have access to a lift, and all the tools you can possibly have.

Question is, would it be best to beef up the suspension other than replacing just the oem rubber? Say, Beefier Sway Bars? Traction Bars? Rear Trailing Arms?

Overall Goal is to make the Lexus very comfortable to drive, looking for that straight from the factory feel.

Any advices, experiences, route to go would be great. Thanks.

 

Hate to say it, what you want is all OEM replacements then.

Poly is great but it is a bit louder than OEM. DO NOT try solid ANYTHING for suspension bits if the noise of taking a bump bothers you.

 

I make poly bushings for a living and have replaced every single piece of rubber on my sc with poly and no added noise or vibrations and the car handles so much better and stays planted and gets much much better traction due to the soft rubber diff and sub frame bushings being replaced with poly ones so basically poly replacements may have added 5% more noise and vibration but how the car reacts when driving spirited is a 100% improvement so replace with the very soft oem rubber if you want the quiet Lexus ride and just daily drive with no type of mods but if you do any type of performance driving you will not regret the polyurethane replacements.

 

I've own this Lexus for nearly 6 years now, just recently I've noticed alot of impact noise within the last month. I plan to keep this Lexus for years to come, even in the market to purchase another SC300 perhaps a 2000 model soon when I find a mint condition unmolested one.

I have no problem going either way, whether it's oem bushings from the dealership or poly bushings. Sometimes I wonder if the New Twin Turbo Supra shocks that I bought 4 months ago became bad? I wondered if that had anything to do with the impact of the road more felt after putting it on and letting it settled.

I've have put the Lexus on a lift and checked out all the bushings regarding the suspension. Visually checked them for cracks,rips, and harden rubber. Even checked with pry bar method as well, they seemed to be fine from my line of work. But being that it's 20 years old and recently felt impact of the road while driving the car, lead to the assumption that the bushings need to be replace for a more comfortable ride.

 

iam going to upgrade to poly and coils. this will be my mid-life crisis car and sometimes track auto-x car. i need the best handling i can get.
