Speedway Control Arms 91036769 - 08/13/19 11:30 PM

I recently purchased a 1968 Firebird that has the Speedway Control Arms P/N 91036769 installed. These control arms are supposed to drop the car 1 1/2 - 2 inches and they currently rub on the tire 225/60R15. Looking for recommendations on which way to go. Smaller tires, different wheels, or go back to the stock control arms. I bought the car with these control arms already on it so trying to "reverse engineer" it.

If anything, what size wheels and tires are individuals running with a 2 inch drop?

Thank you!



Body bushings are shot. That is one thing I didn't even consider.

Should make a significant improvement then! Do that first, then reassess if you still need additional changes.
