Beside being able to install larger diameter tires, advantage or dis-advantage of moving front spring eyes rearward? Whats normal or maximum amount allowed? I have read some of 3/4 or one inch. I think it would move rear hangers to a bad angle?
The "allowed" amount comes from class racing rules, like NHRA Stock & Super Stock. It limits the amount of difference from OEM specs as well as difference from side-to-side. Some racers staggered the wheelbase from side-to-side to gain more rollout, thus giving faster ETs. Made it difficult for good, consistent RTs.
