I've recently got my 240 up and racing. I'm experiencing a bizarre issue that hopefully some of you racers have an idea on. When decelerating from high rpm in 2nd and turning, the inside rear wheel hops violently. If I give it gas or brake it stops, but it upsets the car and freaks me out!
Current setup:
Kaplehenke coilovers all around. 500# springs front, 250# rear. Koni race shocks front, bilsteins rear
28MM front bar, 16MM rear
Ford 5.0 with T-5, stock 3.73 volvo rear with open diff (for now)
Kaplehenke torque rods, IPD adjustable Panhard
17" x 255 autocross tires (RE-71Rs)
Recently replaced original rubber TABs with poly bushings, made no difference. Still have original rubber front trailing arm bushings, which seem fine.
Any ideas? Too much engine braking? Slop in the rear end gears?
