I have no dog in this fight since totalling my IT7 in May and having parted most of it out already. However, if given the choice between the two options I'd have to go with the FI, no dizzy, better brakes, no adapters, etc.

Why take two steps forward and one step back?

BTW, anyone need a 3 link & pandhard 4:88 LSD axle, or a set of RA1 rains, or 7 heat cycle RA1 shaves, or a couple of complete race prepped front struts with Tokicos and brake ducts?
