Newbie with rear gear question.
 

First off I'm new to 240's and I have a question.
Question is.... who makes different ratio ring & pinions for the rear end for these cars ? I'd like to find some steeper gears to help me come out of the corners a little better. ( my car is used for circle track racing )
Also are the any sites that I could look on that might have used ones ? ( I've tried E-Bay with no luck )

Thanks.... " Hitman "

i d try car-part.com and look for a j30 93-97 rear chunk (6 bolt) with a lsd and i think it has like a 3.90 ratio
