I dont do very much street driving but so far with what I have done it hasn't been an issue. My car is too low for stops. They have all been removed. The most recent stop I had to remove was the stop above the rear differential. When I went to the 315's in the rear I had so much more rear grip that I would hit that stop excellerating out of the corners, car would squat, and then pivot on the stop. Pretty crazy feeling.

One thing I want to add.....my feeling is that with auto cross and 200 tread wear tires you probably want 3" of compression due to the tighter turning angles. Reason being.....100 tread wear tires will hold grip better than 200. Once you hit your compression limit with a 200 tread wear tire it will want to slide.

Shocks are going to be your best friend in everything you are trying to achieve so get intimate with your shock supplier. Corner weight the car and have the shocks valved properly and at a minimum get double adjustables. In addition, find the ride height you are looking for and be sure the shock you buy is designed for that ride height. If your on a budget look into Afco's pro touring shock. They are $300 a pop. If you cant find them let me know and I will dig up the part number.

The front suspension is complete allowing slightly more than 3" of wheel travel in both directions. I am contemplating putting a bump stop on the compression side limiting wheel travel to 2.5". If I do this, I should not have to modify the inner fender structure and limit the modification I need to do to the inner wheel well. I just don't want to be on the stops ALL the time. I also don't want to have to make it too stiff to keep off of them.

When it is closer to fully assembled, I will put it on the scales and get the corner weights. I have used AFCO products for years in circle track racing. They make nice products, but thanks for the tip.
