Steve: This is probably overkill, but I'm very anal when it comes to information. I was doing some research and your Speedline (SAC) wheels are actually Type 2310SC (18") and there were also Type 2308SC (17"). Speedline at the time did not have names for their wheels, only number designations. In reality, there is very little difference between the Type 2310SC and the newer Aliseo - just a little less "dish" to the wheel. If your interested, in Issue No. 14 of Forza (December 1998), there's a great Speedline (SAC) ad on the inside of the back cover showing your wheels, along with the F355 Challenge wheels, the Speedline 288 GTO-type wheel, Testarossa knock-offs, etc. Best, Scott
