FYI, I ended up buying some used Enkei RPF1's (17 by 9.5) on FB and just put new Falken 615K+ in 255/40 on them. These wheels are 38 mm offset. I had to use 10 mm of spacers in front to clear the FA 500 coil-overs. In the rear I have 8 mm spacers. The new wheels dropped the chassis un-sprung weight by 28 lbs. I am looking forward to track events this season with the new shoes. DP
