I bought 18's for mine that came from a 911. Because of that, I had to get 20mm spacers which I got from
Wheel Dynamics. Give Eli a call (you can find his number on the site) or shoot him an email. The quality of the spacers is excellent and they are hub centric plus I found the price reasonable. I am still debating on pushing the fronts out a bit to even them out with the rears.
Congrats on a great car and for the price you wanted
