Don't worry homeslice. I gotcha
. Read this thread from front to back. The guys from speed depot know their stuff well. The rear offset will be +35 for the 20x10 Nurburgring and that will be plenty and sit well, and allow a relatively large width tire in the back. Now, the front comes in +20 or +35 for the 20x9 wheel. Speed depot says they recommend a 20 mm offset, and state that a 275 tire in the front can be used without it sticking out at all. Then again, you are lowered and so am I. So, contact them and see what they recommend for being as low as you are. The fronts at a 20mm offset may be perfect. Then again, with a really low car, a 35mm offset in the front may be a safer bet. See if you can get ahold of Speed Depot and let them know you are lowered 1.5".
