WTB: 4.10s
I still dont know for sure what a 3 series is...
But, these came off my 2000 SS with ASR and ABS. If that helps.
Ring Pinion 4.10 Motive Gear about 3,000 miles $90 plus shipping.
Ring Pinion 4.10 Richmond about 20 miles $100 plus shipping.
Both of these were a bit too noisy, not for me but for the wife.......grrrrrr.
With radio on and loud exhaust its cool.
I went with a set of GM 4.11 they are quiter and much more $.
Good Luck.
