Out of curiosity...does saleen change the gears in the S281 or do they keep the stock GT ones in them?
Actually in 99 all supercharged s281's cars came with 3.08 gears. Most likely for epa and fuel reasons, but it probably also helped the top end a wee bit as well. If i am not mistaken, i have seen 3.55 optioned on a variety of saleens at team ford in atlanta. Not all being n/a, but they may have been dealer installed options.
