I am considering putting 4.08 gears on my Stillen Supercharged stage 3 Roadster with a Stillen A/T valve body upgrade. What do you think? Should I do it? How much do you think my 1/4 mile times would decrease? Will it have any adverse effect on my current system?

 

1/4 mile times would more then likely get faster. MPG on the other hand will suffer quite a bit.

 

Yeah, 4.08 are some pretty damn short gears. I say you go for the 3.9 instead, MPG wont suffer that badly

 

My husband requested a price on the 4.08 gears today. The dealer will give him a quote for the part and installation.
