John --
It's a real gamble running with the 235's. I run 235/40zr17 tires in the front as well. For me, dealing with the wide tires in the little itty bitty fender is a hassle that I think is well worth the added handling that results with that size, vs. the next most common width 215.
Here's what I did to solve the problem:
1. TEIN Coil-over suspension. This lets you easily adjust the height so that you can find the exact height where there is no rubbing. My car currently runs at about 1.2" drop. Your car is probably down to about 1.5-1.6" now.
2. Even at full lock, you may experience a tiny bit of rubbing, like I did. The edge of the tire is touching these two inner ridges in the fender. Why Honda put these little ridges there, I'll never understand. As far as I can see, they don't have a purpose being there.
This is going to sound crazier than it actually is, however, I used a small mallet to shape the ridges down to be flush with the fenders. Problem solved.
IMO, the Zanardi suspension is low-value considering you can get a coil-over suspension for not much more. (Disclaimer, I sell the TEIN suspension).
Cheers,
