last I saw umi does make a dedicated set of upper control arms for that swap as it's not a slam dunk otherwise.aside from the control arm issue the 12 bolts are wider than the stock 7.5's.people wind up running a greater backspacing with their wheel selection also.

Without a sticky tire at the track, yes if it’s in proper working order.

Yes, thats 7.5". You can tell by the little fangs that hang down at the 5 and 7 o'clock positions

Everything depends on how you actually use the car. A pair of swaybars alone with make a huge difference. I've beaten the crap out of my 7.5 with less power. Not saying it's bulletproof with a girdle cover, but if you treat it right it'll get you home.
