Thanks! That is some really great information. I like that the front and rear control arms are the same. Very cool! I saw the control arms at Tarett. I assume these are the ones:
GT3 Control Arm Kit, 996/997/986/987/981/991
I know 10" of extra body is a lot to attempt. After considering my wheels, I actually need to go 8.5" wider in front and 4.9" in the rear. I really hate to run 2" spacers. I think that would not be great for my bearings. Can I really only get 1" per side on the wide track? If that is the case, I may have to do something really custom. I will eventually give those guys a call. I am serious about doing it but not right now. I have a few other things I need to work out first.
