Earlier models with non Z rated tires ie. RSA's (which are now Z rated) had a "limiter". maybe he didn't want to waste gas ? :dunno:

If they come from the factory with Z rated tire then the cutoff is somewhere between 155mph and 163mph. depending on the Z28 and SS.

my SS i used to have was around 162mph.

That would suck! There would still be another 3 gears to go with the M6!

My buddie has a 00 Z28 A4 (bonestock) , and it cut-off on him somewhere around 120ish , kinda sucks - he found that out while racing an RX8. It doesnt do that anymore though , he bought a handheld programmer.
