i posted a tire wear thread and everyone recommended getting upgraded bushings, I decided to get with the Lexus bushings (RCF) ones from hollywood Toyota aka discount monster.. had them installed today but I do not feel a difference.. car feels more stable at higher speeds 70mph+ but besides that I’m not sure what I should look for. I asked the mechanic if he noticed a difference between my stock bushings (2015 IS 250) vs the new bushings and he said no but he felt that the rubber was more stiff.. I think he thought I was doing this for no reason lol.

Can you guys tell me what differences I should look for?

 

Brake hard and see if the car feels more stable. I know with my RR bushings it has greatly reduced the nose dive.

Also, the steering should feel more precise with improved feedback.

 

 

 

Yeah, just drove it after reading the comments, breaking hard, car goes straight, doesn't move.. steering feels a little bit more planted, close to stock. High speed driving is a lot more stable, I was expecting a bit more but it's fine.. But, another question, why do the bushings look identical to the stock ones? They literally look the same.

 

They're of the same design to the originals, they're essentially just stiffer rubber.

Yeah, mechanic told me the rubber was stiffer than original but he thought it might be because they are "new" and will wear off, I guess its doing the job.

 

 

I kinda doubt that. AFAIK older bushings become more brittle and tear into pieces, unless petroleum products were leaking on them during their life, which would make them softer...

 

I have a 2014 rwd gs350 f sport and I just installed my sets of gsf/rcf bushings today. The feeling through corners now is exactly what you described it to be.

I found that the stock bushings on my car had a larger ​​​rubber diameter and softer compund than the gsf/rcf bushings

 

Just out of curiosity, where does one get these installed? I would love to do it myself. But i don't have the tools, nor do I have a driveway or garage. Would a tire shop do this? Or some sort of suspension/brake shop be advisable? The only lexus mechanics in my area are the dealer and a place called integrity auto.

 

A simple mechanic shop should be able to do the job.

 

It is a 30 min job from start to finish. Do not pay more than 1 hour labor to have it done regardless of where you go.

 

A few questions for myself, and those that might find this thread in the future.

1. Can you post the part number, quantity, and maybe a link to where you bought them?
2. Does installation require an alignment?
3. Are there any stock alignment settings that can be adjusted to help the tire wear as well? Or should the stock alignment settings be used?
