There is absolutely no noise from the RRRacing bushing when driving
this.

i also balanced my front wheels as RR-Racing suggested.

im on swift springs front and rear

honestly.. i cant tell the difference in ride quality so that is a plus to me. maybe the roads i drive on are smooth but i cant feel any increased NVH.

Thanks for the input. I was actually going to have them rebalance all 4 and do an alignment with the standard service

I just installed these today with DC Guy and I would have to agree with the quotes above on the steering & NVH.

What I noticed the most was the stability and the braking feel The car feels great when you brake and the unsettling and numb feeling that you would get from braking hard, or from braking at high speed is gone! Fantastic Mod!

^ agreed installed mine 2 days ago the feeling of the car when braking at any speed changed 100%
I'm in love with the car again ...you do feel imperfections in the road more but i don't mind i like the sports are feel ..i also installed a strut bar and i feel more confident turning corners fast i feel the car is more balanced with the addition of both items

i would recommend this to anyone looking to get it...you won't regret it

After reading thru this thread it seems like these USRS bushings will both improve steering response and reduce inner tire wear.
I noticed a difference in feel/response (mostly under braking) with the Figs bushings. It's been so long now, that I'd have to drive a car with this USRS set to see if there is a significant difference.

What's certain, is that either upgrade benefits over the factory bushings.

After a few days of driving with the new bushing I'm noticing a lot of noise on low speed bumps. Pops and clunks.. Anyone else noticing this?

Installed mine with MileHIFcar on sunday. Main things i noticed, steering was a bit tighter, braking hard feels incredibly more stable, with the factory bushings the back end feels like its about to come off the ground, throw a corner in, with heavy braking is just about scary as hell. So glad this has remedied the situation. During hard acceleration, i feel the car stays more forward in "attack mode" without as much front end lift and added stability. The extra control has made more room for comfort when I get a wild hair you know where. Overall, great mod especially for those who track their car. I personally wouldn't consider it night and day for say... but, given my bushings only have 13k on them, I would assume they get worse and worse over time, and some may have that incredible difference. Quality built product, great price, lifetime warranty, Simon and Rafi are always there with outstanding customer service and the itch for improving the F. As you know, not many are investing too much time given the small F crowd. Hats off to RR Racing. Great mod. Thank you!

Did you tighten all the bolts to spec ...you should lift her up and check that everything is nice and tight
