Sfc?
I'm running SLP weld in SFC's and love them. My car is lowered about 1.5 inches and they are great for my use. There are many good choices. Look at LG Motorsports for another excellent design. There are others as well....

Also might I suggest you look at the Hotchkis boxed SFCs and the BMR tubular or boxed SFCs. I personally have the BMR tubulars and they work great with absolutely no ground clearance issues with my lowered car.
