Hey everyone got a find today we had a set of mercedes wheels that we took to the scrap yard to day at work. the man who bought the car wanted different rims and they were sitting around. so the boss told one of the techs to take them to the scrap yard, anyway the boss let me keep the tires they had 10 miles on them brand new car. The size is 245/40 zr17 the sppedrating is Y has anyone run this size on there GTO. im wondering cause there 5% sikinner i know it will sit lower and the gap will be bigger and the speedo will be off a couple mph.there michialin piolt sports and free
Thanks Eric

theyll work fine. just the speedo will be off 3.8%, so when your speedo says 60, youll really be going 57.7

if i remember right, the Predator Tuners are capable of compensating for gear and tire size changes, I believe Spunky has/had one...they might help you out if so, or anyone else w/ one for an 04. Do the dealerships not have anything that can flash for it? J/c. I wouldnt mind getting the 05 Predator just so I can remove the T.Speed limiter, and be able to compensate for the diff. gear ratios and tire sizes. Just ordered the05/06 A4 Performance TCM module off Chris(GTPPrix), next up are shorty headers, etc...good luck w/ it, freebies are always a good thing

I'm thinkning it would look good w/ the front SAP extension, w/ the middle peice painted to match, not the grille, but the dark section in that area, looks something like D_____D(obviously this d would face the otherway)
