Fantastic product, totally silent, IMHO perfect final drive ratio (3.64, still good to hit the 155MPH speed limiter in 6th given the opportunity) and the 35/60 ramps are totally smooth and predictable. Moderate lock on decel is sublime. Second photo shows clearance to the stock exhaust.

Great to hear - I am surprised to hear how much you "feel" the diff even in street driving? When you say the lock on decel is great, what is it you feel has improved? I'm just trying to get a handle on real world changes to the way the car drives at 128i power levels.....kind of a "don't know what I'm missing" type situation as I'm not really able to spin the inside wheel on the street (obviously I'm not driving like a maniac on the street).

I can feel the diff doing its thing just pulling on to the street from the driveway. Too often doing just that the traction control would kill power and apply the brakes. Scared me a few times pulling into traffic (or I could just wait for more space between the cars )

Decel is weird only because I've only had my too short shakedown run to feel it, and I was very surprised I noticed it as much as I did. Car felt supremely planted, not that it didn't feel planted before but even more so now.

I can't wait to get more quality seat time.

My Hotchkis RSB finally arrived (ordered 2 June!), but now I won't have a weekend to install it until at least October! Heck, if it had just arrived a week ago..

I've got very similar ramp angles to you (30/60) and I agree that decel feels surprisingly good. Rear end feels SO buttoned down. The diff & the RSFB's really make this thing feel like a real sports car, IMO. I think you will enjoy the rear bar, as well.
