On racecars, fixing this is relatively simple by changing suspension parts or moving the suspension pick up points on the chassis. On a street car, it is practically impossible to move the pick up points, so you have to do more exotic things to try and maintain a reasonably short roll couple. One of the most innovative things I've seen on a 2IS is putting a spacer block underneath the front upright above the lower ball joint. This lowers the car without creating problems for the lower control arm - unfortunately to get it 100% right, you'd need to shorten the top of the upright by an equal amount - it could be done, but would require a custom forged upright. If the 2IS were serving track duty somewhere, it is possible these parts would be made and available to the public, but since the 2IS isn't actively involved in a road racing series, I doubt those pieces will be produced.
It's a little disappointing the F didn't take the custom upright approach, it would have been a really simple fix for the rest of the 2IS world to lower their cars without having to resort to super stiff spring rates. See below for the part you'd need to mod and where to make this happen:

oztiks, been following your situation and glad you got it all worked out...what settings did you finally settle on? And how would you describe the ride compared to stock on regular roads and/or freeways w/ expansion joints, etc? More compliance in everyday driving? Thx much...
The ride is completely different than stock, in my opinion. The car is much more compliant for every day driving, and doesnt get that nasty "hop" on freeway expansions, etc. The stock suspension was so firm I could get the rear end of the car off the ground on i95 doing 50+MPH on a particularly bad part of the road. With the new suspension and the same part of the road, the suspension definitely takes a hit - but the car stays planted and firm, and it doesn't crush my spine.
Thanks for the link! Interesting reading.

Nope.. would have even happened at stock height, but might have been slightly less bad. I was in a hurry going to verizon to get my phone back (long story, they had it all day) and thought they were closing. They have the worst parking situation ever, and there's about a 6-8" high concrete sidewalk right in front of the parking spaces - with no curb stops. I effectively used the sidewalk as a curbstop....... and then found out they were open for another 2 hrs

Lexon is the only one with a lip out right now for the F (correct me if I'm wrong). I believe AutoCouture is releasing a lip for the F soon. The Fox Marketing IS-F body kit featured on their orange IS-F at SEMA is supposed to be released by bodykits.com "sometime soon." I'm not sure what exactly the body kit comes with though (would assume side skirts and front and rear bumpers but I'm not positive
