I believe its more appearance preference than anything else, but widening the wheel base should give better lateral stability while cornering.TennGT said:Any alignment or reliabilty issues with using these? What is the biggest benifit to running them on a late model mustang? Any track or autocross times to back them up? Thanks this is a mod I have been thinking about for a while.
Its called power oversteer my friend. You have a Sean Hyland long block, use it! My friend just got one for his 99 cobra, and man its awesome, especially with the 12+ psi he's pushing.Ralph Greene said:They (rear spacers) would be only for looks. Adding width to the rear adds rear bite, which causes even more understeer or "push" than we already have. For handling, we don't need more rear bite, we need more front bite. It's the fronts that need to be made wider (for handling), not the rears. But it does look nice to fill up those rear wheel wells, even it that's the exact opposiite of what we should be doing (for handling).
I like the looks of my 18X8.5 front wheels, and 18X10 rears which gives it that wide rear look, but it didn't help with handling at all.
