Seriously guys this is getting to complicated, what's wrong with the way it was designed, if all you want is a quick track car why didn't you buy a track car, I believe you can over think these issues to the point of ocd, and there are very few cars to beat the sc and all the time and effort for maybe 1 second doesn't sound good sense to me, but am I missing the point of why you feel the need to do all these alterations.
