I have 3.55 gears, McLeod street clutch, lowering springs, caster camber plates, control arms, BBK X-pipe with cats, and an Explorer TB with a 70mm T-Bird MAF housing and '94-'95 Mustang MAF sensor. The TB and MAF made a huge difference.
Subframe connectors are on the list to install this summer. I'll also probably install my JBA shorty headers.
