View Full Version : Need an E30 diff soon

05-06-2004, 10:00 PM
My back end is grinding on acceleration from right first into second and have narrowed it down to being a problem with my rear diff. I don't have the time or cash to swap it yet but will be needing it in the next month or so. Just ket me know if anybody has anything come up. Thanks. -BJ

Hey man, to tell the truth I don't know much about diff ratios. Which would give me the best performance here and which is the stock ratio?? Let me know how much you want for each and I'm gonna call my mechanic next week and see how much he wants to throw one one. Like I said earlier, I'll get back to you in the next few weeks when I scrape the $$ together. Thanks for the reply.

i have no idea what ratio the i is(too tired to look it up)a 2:90 would be great for highway cruising and gas mileage,where a 3:73 is more for torqueyness and acceleration...all depends what you want...and i can install it for you,takes about 1 1/2 hrs with hand tools..i'll get back too you with a price..
