just installed BBP axles,Dr Diff offset kit along with zero arch oval track springs. When I set the car down off of the jack stands the forward portion of the springs went into reverse arch, and it appears that the springs moved the axle toward the rear of the car more than the 1/2" that I was anticipating. There is only about 1/16" of clearance between the differential and gas tank also. The reverse arch is looks worse than the pictures show. Are all the things I am seeing normal with this combination of parts ? Does anyone have wheel hop problems with the oval track springs?
