Terry, I feel your pain. I also like to go canyon carving, and as I mentioned in another thread, I've whacked my sump (and merged header) a few times.
I guess we only have a few options:
1. slow down (doesn't help-I whacked my sump going over a big speed bump)
2. raise the suspension height (not a good idea-looks goofy and hurts handling)
3. go dry sump (a great way to go, but too complicated for me)
4. larger diameter tires (185/65-15 has a 24.5" diameter-205/65 has a 25.5" diameter, so a ground clearance gain of 0.5")
5. larger wheel size (a 205/65-16 has a diameter of 26.5". That's a ride height
gain of 1". Might look weird, though. 205/60-16 would look better and at 25.7" give you a 0.6" gain in ride height. Also, 16" wheels would be heavier, which is a real negative for our light cars)
6. go without a sump (on a big engine like I have it probably isn't a good idea)
I have Koni shocks and I think my back shocks are set at 3/4 stiffness. I may take the rears off and change the setting to full hard-see if that helps.
