Default 3.90 Gears

Just curious if these gears are made to fit the factory 10 bolt....they seem like the perfect comprimise between the 3.73's and 4.10's. This would be for an M6 also.

well 4.10 on stock tires is 116mph( with stock rev limmit)..and usually to get over 116mph you need a cam (or n2o) and with a cam you usually raise the limmiter to 6700..which should raise your 4th top speed a few more mph

AFAIK, the ONLY company that makes a 3.90 gear is Richmond, and for a 12 bolt only. 3.73 and 4.10 only for 10 bolts.

lots of companies make 3.90's for both 12 and 10 bolts, but not for the 7.5 ten bolt we have
