I am afraid to have an error code due to different ABS/DSC sensors.

"If the diff in the picture is a an auto and a 188 case the just swap in your diff and be done."

Sadly the diff. in photo if from a 6MT so it is a 215 one.
Thank you for the 188 measurement --> 11" (215 case) / 10,5" (188 case) is not a big diff-erence (0,5" ; ~13mm) considering the axles are a little "stretching" maybe that i can make a test and see if it match with my diff?

Are you happy with the 3,73 diff? not too tired on highway?



Thank you for your help!
here is what I used
135 hub/carrier/sensors/brake calipers/rotors/ebrake shoes
128 manual diff 188, later swapped in 328 188 3.73 from auto
328 auto axles
stock 128 driveshaft

things I added as upgrades
M3 arms
M3 subframe bushings
Braided brake lines

I got used to the 3.73 and its great for the track. I don't do much highway on it all but once a year.

What I dont get is why 128 guys just use dans diffsonline and stay away from messing with the rear pumpkin size and output, its about $300 more but you keep the stock driveshaft and don't have to squish axles?
