After following some of the wheel/tire threads linked by Musterion and others I once again looked up online the TSW Nurberbrings that many have used in 20" variety and see that they now offer 21" rims. That should allow me to now do exactly what I originally wanted with 245s up front and 285s rear using Michelin PS2s. Will probably go 21x10.5 on the rear rim and 21x9 front. I have an America's Tire nearby that has helped me before and am going to check with them for the install work. I'll let everyone know what I find out.
Awesome! Can't wait to see your results. I'm about 4 weeks away from 9" fronts and 10.5" rears. Post some pics!
