Acceleration difference is huge! As far as cost, besides the gears, you will need an installation kit as well. My total was around $600 for everything and well worth it.
Properly done it's about 4 hours. On a new car you won't need a complete installation kit just a gasket and MAYBE a shim or 2.AdamZx3 said:Hello all, This is my first post though I have been lurking around here for weeks researching, one thing I noticed is that allot of people are running different gears, I am getting a GT in the spring and am looking into new mods. If I bought 4:10 gears how much of a difference would it be in acceleration? even if its the seat 'o' the pants dyno.
Also I have seen FR gears for around 150 I or so, how much would a shop charge to install these?
