If I convert my '91 Indy 500 over to a Xtra-10 in the rear, should I convert the front over also to keep the sled balanced? And what would I need? Different trailing arms? I assume the shocks are taller also? Thanks!
I agree, it's not necessary. We're talking about 2 inches of ride height; you won't notice that you don't have it. If you were to swap out the front suspension, you would need XTRA 10 trailing arms, shocks and radius rods from the donor sled.
The early on EXTRA-10 suspensions had no extra travel in the front any way. If you look at the specs the rear had the extra travel, but the front maintained the same 8" suspension. It was all a marketing gimmik at the time.
