any members interested in me making a better and easy to follow/understand DIY on this? Mine was suppose to be delivered today but i wasn't in town. so i might install it tomorrow or friday.
Ive been working on cars for a long time now, there are certain things new people can do and somethings left to the professionals. but for this, its pretty easy as long as you are a normal strength guy.
I think RR racing's post scared a lot of you guys because of the terminology. for a seasoned DIY guy, his post was understandable. for the rest, it sounds like something you want a shop to do. but i would say this is step above an oil change and i can list exactly what to buy in terms of tools/grease.

The bushing comes pregreased so it should be ok. Rafi said in the 12 months of testing they had no issues with noise or squeaks.

With aftermarket parts replacement, our ride wont be comfy as it used to be in oem form but these parts will bring out the best of our car for certain designated scenarios. Right after the installation, i can feel every rock on the road during my drive back home. I then readjusted the compression on my coils and the ride is great now. I also noticed the car is much more stable when driving through a metal grid section of a draw bridge, even when it rains.

How does the steering wheels feel ?? Any vibrations or just more of the feel from the road ( meaning feeling more of the imperfections )??? Thanks for the reply.
Looking forward to getting mine installed

Steering feel a bit heavier/ tight but sharp and responsive like on the 335i. Made you feel like you're driving a 2 doors sport car. Because the bushings are 95 duro, it is hard, so you will feel the road surface. The OEM bushings are very soft and rubber like. They absorbed any vibration and flex too much causing steering delay or less responsive. Highway speed VERY stable. Some one mentioned our car is too heavy for autocross. Well, install these and have the proper tires then you'll think twice 
Anyone else who had these installed, please chime in and share your opinion as i would like to know what else these bushings can do. I only drive my F in the weekend minus rainy days(vented cf hood lol) so i dont think i've explored the most out of them yet.

Thank you ISFPOWER, I've been busy on the next 2 products we will introduce shortly:-)
Regarding the 0.020" feeler gage, you SHOULD NOT be able to do this:

installed mine earlier today. i drove on the exact same roads i take to work and back to really know how diff it is. here will be my quick review. mind you, i have the 95 duro bushings.
there is definitely more chassis vibration. my steering wheel doesn't shake, my pedals doesn't shake but you can feel it in your butt if that makes sense. almost as if your rear tires are really out of balance but for the front of the car. i drove the car on many diff types of roads. driving slower on bad roads, the car feels rough, stiff, more interior rattle , the usual road imperfections i usually drive on feel much more harsh when hitting them. little imperfections feel more dramatic...a lot more.
On smooth roads, feels exactly the same the same. can't tell i changed out anything. smooth/quiet.
mind you, my front tires are bald on the inside. thats how soft the oem bushings were. my bald tires were smooth and quiet with the oem bushings, and kept all of the NVH to non existent.
I have new michelin super sports in the closet all around that will be installed with a new alignment. My camber right now is about 1.4-1.8 front rear is .08-1.0. so its def getting contact patch on the road. also like Rafi said, when he put his on, he had vibrations in his steering but after he balanced the tires out, it went away. basically, if you have any pre-existing problems, they will be apparent with the new bushings.
the good things are that bump steer is almost all gone. feels great on freeway going fast. steering feels a bit heavier in a good way. more solid. and mine was already solid to begin with. steering response is better, corning feels better but most importantly BRAKING feels sooo much better. stops hard and quick and steering wheels stays straight like an arrow. i haven't had that feeling since the first day i put lowering springs on my stock F. since then it slowly went downhill on the braking.
Im going to make another review when i actually have all new tires that are suppose to be quiet and sticky tires. also my alignment has to be off because ive been playing with the height settings a lot lately on my coils while waiting for these bushings to come in. I think my negatives are due to my bald front tires and alignment is off.

USRS Color Survey!
Hi Guys!
We are glad that the RR Racing Ultimate Steering Response System (USRS) has been such a success and received so many good reviews. We are now backordered on this product, but no worries we are making new ones as fast as possible.
Before we finish the next lot of USRSs, we would like to make a quick survey. You noticed that we black anodized our bushing housings. Some people expressed an interest in IS-F like blue anodized color. Since we cannot make both colors, we would like to get your feedback what color would you prefer.
Please respond on this thread or send us a private message.
Thank you again!
