Hey I have a 1995 firebird formula and she has lots of noise in the rear end howling and i heard that it could be the gears so I was thinking of changing to 4 10's so please just let me know if you think 4 10's are the best. I have
CAt backs
Tuned
and short throw
thanks!!!

 

4.10s are weaker due to more/thinner teeth on the ring gear. That's a lot of gear for a stock motor.
