ah shoot, knew I forgot some info, I've updated the original post with offsets, weight, and tires
no rub at all, actually could have gone a little more aggressive
I have yet to take mine in the 87, but I look forward to when I'll have time.
PS, my buddy keeps telling me about the blue Z he sees around the Scottsdale area, I just don't make my way there that often (from the West valley)
Throwing my 2 cents in here. If you live in a hot climate, avoid cams with a battery in them. Here in AZ, they wont survive a single summer if you park your car outside. Instead, look for super capacitor cams, like Rexing. I also have the Dongar adapter and make install super quick and easy.
Just installed the Gruppe M system. Not difficult if you know how to follow Ikea like directions, took a couple hours.
Now to aquire a carbon engine cover.
