My new rims/tires have arrived!
TSW Nurburgring 18x8 (35mm offset), 18x9.5 (40mm offset), matte gunmetal
Nitto 555, 265/50-18 and Nitto 555R, 305/45-18 - these maintain the stock height.
Special order (very good price) from (not listed on their site, but here's the 20" version):

Here's the kicker:
Fronts weigh 50.5 lbs each vs. 62.3 lbs stock.
Rears weigh 53.5 lbs each vs. 68 lbs stock.
Sweet. Only thing required to mount is get rid of the roller skate front brake pads (you can replace them or chop off just the roller skates).
Sorry no pics mounted yet. I'm away for a conference next week and want to use the stock rims/tires/brake pads for my 12 hour round trip.
But next week, I'll mount them up, and weather permitting, I'll get back to the track with these being the only difference. So we'll see how they hook and how I do with a 1.7 or 1.8 sixty-foot.
