Has anyone continued to experience inner tire wear with the USRS? All posts prior to me installing the USRS stated a reduction or elimination of this issue and I was wondering if anyone continues to see significant wear after the installation. Also, what driving behaviors contribute to this inner tire wear? Is it hard braking? Low speed "full-lock" cornering such as U-turns? Aggressive turn-in on corners? All of the above? Any ideas on how to further reduce inner tire wear? My tires are certainly wearing better than without, but the inner shoulder is wearing at a rate that will possibly still be quicker than center tread.

I have the rr racing usrs since it came out and i dont have any problems with it. Have you get an alignment after the installation?

I've had no inner tire wear since installing the USRS last year. That being said I did have some cupping on my last set of tires (Nittos) because I never got an alignment last year when I had the USRS installed which led to some major out of Toe specs that contributed to those tires early death.

Since I learned my lesson last year that was the first thing I did when I got my PSS tires a couple months ago, and since I had an alignment and had my Toe set to 0 I've had no issues with inner tire wear (knock on wood).

Have had mine for ~7k now, no irregular wear. I think it was how the wheels moved under braking that caused the inner tire wear before, not sure about that.

No irregular wear at all on mines, and I've had it for 15k miles.

This is accurate. If you are still getting inside wear, you have more toe out than you need. I run mine a little toed out because the car turns better but I know it means inside edge wear and I accept that as normal for what I want. But the wear I am experiencing now is far less than what I previously had with the OEM bushings. BTW, I am using SuperPro bushings, not the USRS. Regardless, any of the aftermarket poly or solid bushings will be better than the squishy OEM bushing.

For those of you running aftermarket bushings MileHiCar, Lobuxracer and others from Figs, RR racing etc how would you describe steering feel and response? Is there any additional hoarseness to ride now after the installation of the bushings

No, and the car doesn't wander under very hard (track level) braking anymore. Very significant improvement.

You'll feel all the good things that people described on this forum for these bushings on the car, just don't drive the car in NYC. You are going to feel every bumps on the road. I don't drive the car into NYC ever since I installed the bushings, can't take these old brick roads/pot holes/bumps.

Glad to hear this! I ordered the RR-Racing USRS Friday evening after having spent some time under the car and noticing the typical inner tire wear occurring. Figured it would be cheaper to order this than have to spend money on new tires prematurely.

I felt more of a difference in the braking dept! The steering response is improved but it was more noticeable with the braking/immediate feel instead of that squishy feel before!

Should be called the Ultimate Braking and steering response system

Thanks for all of the comments regarding the inner tire wear and causes. I will agree with many regarding the increase in "harshness" felt through the new bushings. It is certainly a more jolting experience. However, I will also agree with those stating the increased performance of the bushings. The wiggle and sidestepping under hard braking are gone, steering in general feels very responsive, and inner tire wear issue is drastically improved over the stock bushings. Thanks again for all of the comments.

Along with braking improvements it's well worth it simply for getting rid of that annoying on-center vagueness in the steering as well, feels extremely tight and direct even before you load it up now.

8 track days on URSR and perfect wear int he front. I only run oem alignment though
