1) any one have experience with the "STREET" version ... supposed to be a little softer than the standard ultimate

(2) since you're planning on lowering, I would personally recommend getting the rear camber arms. I too am lowered on RSR Downs and did my own alignment (I'm a technician by trade) and the drop puts the rear camber quite negative, not out of spec, but definitely noticeable. Just in preventative nature to save your tires, definitely get the adjustable arms and get an alignment rather quickly after install. I can post up my specs if you would like.

dude ... thank you for the detailed response.
and yes, i did just order the SPC rear camber arms. thank you for tip.
this is really stupid question ... with these extra adjustment points, do i need to look for a specialized alignment shop?
are the rear camber arms something you set and leave? or will they be used to adjust at alignment

Most alignment shops will be able to handle the new control arms. I will admit they're a slight pain in the ... to get a wrench on, but really any competent shop won't have much issue. These control arms are used to adjust the rear camber, so as for "set and leave," technically yes they are, but only after u get the alignment where you like it. If you decide you want a more aggressive, track oriented alignment, then it's back to the rack to change.
However if you're like me and are looking for longevity of tires, I set my alignment for straight city driving and hopefully wears the tires well.

(1) I bought the street versions, the durometer is *I believe* slight between street vs race, something like 88 vs 90 or something. What I did notice is road noise went from slight to quite noisy. It's certainly not unbearable but it is noticeable. I did notice better turn-in grip and more feel in the steering wheel. I will say I do nothing but normal street driving, no track, so there's that.

Shane,
Thank you for this info! You are the only one I could find that has used the street version of the USRS instead of the one everyone uses at the 95 dur system. I want to keep noise to a minimum in terms of overall ride quality and was thinking of getting the street version over the normal system but feel now even this might be nosier than what I am hoping for.
Appreciate your input!

Really what it comes down to at least for me, is do I sacrifice a little bit more road noise to ensure my front tires last much longer, or do I buy tires every 15k due to inner tire wear? Like I mentioned, the road noise isn't unbearable. And after doing my alignment and setting it much more street friendly, it took away a bit of the noise the bushings induced originally.
Personally having done them and driven with them for about 60 ish miles, including some highway but mostly city, I would continue to recommend them to everyone just to save the tires.

I don't have a video, and it would likely be hard to pick up on video. Perhaps it's my sensitive hearing, but I would guess road noise increased by maybe 15%? A lot of people noticed some difference. The factory ones as you know are soft as hell so they absorb a lot of potential NVH from the tires, whereas these poly just say screw it here's everything.
But to put a positive note on you saying you didn't hear a difference, it can tip people (such as Nigel above) in favor of buying them if they're on the fence. I honestly think it comes down to the individual as to if they hear a difference or not.

I have street version too and I feel the grooves of the road a bit more, kinda adds the bounciness if anything. But steering definitely improves and hoping to see more even tire wears (only been 2 months, so fingers crossed!)

you're not going to avoid rear camber arms because I just got my tires swapped and my inners were wearing pretty heavily in the rear at about -2-2.5 degrees (which is still in spec) on RSR downs.
don't know why you would want these bushings as they periodic lubing (involves jacking your car up and applying) or it will develop a squeaking noise. i have the RCF/GSF bushings

Most drivers would settle for the RCF/GSF bushings. I had them on my IS300 and didn't feel any difference. I think the only benefit with the RCF/GSF bushings is to eliminate the premature front inner tire wear.
Bottomline, I agree with the periodic lubing comment, that's why RR-racing developed the new enclosed "race version" bushings(claiming re-lube maintenance free), but I think that also won't eliminate the NVH behavior.
I'm looking forward to their "street version" of the enclosed bushings.
