Does any one know of a good six speed that will fit in an '06 SS/SC

 

quaife has one

 

Not worth it unless you're autocrossing. Costs $3,000+ IIRC, won't save any gas in top gear.

 

Quaife makes a $4000 kit to change your F35 into a six speed... Not worth it in my opinion...

 

looking at the gears it will give you a usable 1st and very good gas milage in 6th.

3.867 final
3.00 1st (takes you to 49mpg)
1.933 2nd
1.368 3rd
1.045 4th
0.883 5th
0.704 6th (highway cruise around 2500rpm)
