Well, why do we run shorty packs for then? Because the car is too heavy??..Whatever works for one guy, is a line of b.s to the next. Ever tried a shorty in an RB5? I tried to run a 22 twice, and hated it both times, after numerous changes the car never felt planted, others think its the bomb..Nobody thought the 22 trans spacer was a good idea, until the guy tried it, and now every (ok, almost) 22 has them.
