Will 3.85 rear diff be to low for DCT car? Just a thought.

Yes, the ratio is too low and the tranny light will come up on the dash. It seems to be too short for the dct software. I know this because I tried it while waiting for my 3.62(3 plate/variable ramps 30/90 from DiffsOnline) back in December which works perfect.

3.85 - why is it too short?
some firms are offering it in Europe?

Agreed - 3.62 is probably as short as you want to go based on my experience....

thx.
3.62 is it that much better than 3.45?
what is the best option for better 1/4 mile and 1 mile race?
