What kind of final drive are you guys running on your supercharged S? 4.44, 4.57, 4.77 stock 4.10 ?

Moddiction

Stock or 3.9 if making over 500whp.

youngkilla

it wouldnt be quicker with a higher final drive? at 400-470hp?

Moddiction

Should slow it down. Even NA I feel the s2000 is slower with the shorter gears. Maybe the 4.44's on an AP1 would help out until 350+ whp but after that you want to be in boost longer.

Habitforming

Traction will already be very difficult in first gear, and questionable in second gear. You will amplify that problem if you go to a shorter (higher number) final drive. I would never shorten the gearing on any boosted vehicle, generally speaking.

3.90 all the way. 1st and 2nd is still super quick. better gas mileage, better highway RPM, better top end.
4.57 if you are NA.


Have you actually bought anything yet or you still planning and asking questions?

Leave it stock. Your Supercharged at 450+whp. Your already spinning tires in 2nd gear and sometimes 3rd.

3.9 final drive is nice for anything over 420whp.
