For great street performance which would you pick and why? I'm going to be using them with the stock R1 shocks for awhile.
The RB are linear and lower the "jacked back" more to make it more even with the front.
The H&R's lower the same all the way around and are progressive (yuck) isn't that an insurance company?
I just want something to hold me over until I get my N1's
Thoughts from anyone that has owned either?

 

I've had both. The RBs with Tokico Illuminas and H&RS with R1 stock shocks. For street/track performance, my current H&R/R1 setup has been fine with me. I don't feel the need to upgrade to a ride-height adjustable coilover setup. The H&Rs are much more comfortable during the daily commute. The RBs were a bit punishing on the tail bone. As for ride height both springs dropped the car considerably. If you plan to road race, you should upgrade your sway bars to complement the stiffer spring rate of either the RB or the H&R springs.
