What to do first Just got a 96 firebird formula and was wondering what mods to do first? I was thinking 3:73 gears but how hard are they to change, will it affect the speedo, and how much will it affect gas mileage and top speed.

M6 or A4? What's your GU code? Any gear swap will effect your speedo reading but luckily its just a flash of the PCM away from being corrected. As for top speed the higher the gear the less top end your going to have.

Youll still go faster than you need to with 373s. It will affect your gas mileage some but not drastically, especially if you dont do a lot of highway driving.
I switched from 273s to 323s and it was a big difference so you will definitly be happy with gears.

i'd go with headers/exhaust,cold air intake,cam and stall ,tires then gears 
also weight deduction. hopefully your suspension is in really good condition otherwise your be spending money on trying to make that beast plant.
say high to low 12's easy on motor........then a 150shot high mid 11's

if you have 2:73s you dont have a 3 series carrier unit so you will need to get that to do any mod in the 3 series... now if your gears are 3:23 then it will be slighty easier, you jsut buy the gear kit and put the gears in....
it will be a tough job for someone who doesnt know what they are doing and you could mess something up, which we all know you dont want to mess that up as it is vital to your car staying intact or wrecked...your rearend locks up your dicked
