That might be good for a manual car but way too high for an 8 speed.

Something in the 2.90-3.10 range would probably be as high as you want.

How do you fix the speedometer error with gear ratio and tire size changes?

I would like to see someone else try first LOL. It looks like the 2.0 has the same tranny as my 3.6 but with a steeper final ratio....

Yea the LTG cars I think I heard needed that to help get them into boost quicker. I was just talking about the LT1 A8 cars for 3.91 being too much.

Just for the record JFM-Jr on here has gone 11.65 118.5 with just DR on 19 in wheels with A8 2.77 gears so gearing is a non issue with 8 gears and 1st being 4.56

That is just nasty!!

Ported intake and ported tb actually. Not just DR only. Im right next to him on the list.

As for the gearing....it could use maybe a bit more but not a ton. maybe 3.08 in the rear.

Does anyone know if that 3.27 gear in the 2.0 has the same ring gear thickness ? Is that an open differential or limited slip ?

[Gen6Rs]

it seems like a shorter tire might physically do the same thing. I wonder what teh differennce is between stock 18" and 20" RS PKG.

Think the manual ones do have a limited slip but not the autos.
