Ahh man. Yeah I was worried about the center bore size - the site doesn't even list the diameter. Thanks man appreciate the heads up. Sucks to give back another 9.5mm of offset - Existing wheels from 0 to new wheels with +30..... minus the spacer -9.5mm = ~20mm offset net. Torque Thrust IIs do have a +25 offset option but they weren't available to ship until May.... and I didn't wanna wait that long for a new front set of wheels. Hopefully +20 is enough for my existing 225/50/17 tires to work without too much fuss.
