When I first built the car, I cut 1 full coil out of the 6308 springs. We bounced the car as much as we could and thought it sat right. First test drive the front dropped another half an inch and rubbed on almost any bump.
I bought another set of springs and left them alone. After installation and test drive, the car is about the same height as I thought I had with the cut coils. I have comparison pics on the website. I have removed the top 2 bolts that hold the fender and inner together and a couple times last summer if I got surprized by a frost heave dip in the road, I got some light rubbing on the edge of the fender. With the bolts removed, no big deal.
I'm running 235/45/17 tires on the front.
