hey all,
looking at getting my LSD reco'd and put in a set of 3.7's, or maybe 3.9's in it.
just wanting to know how much of a gain 0-100 roughly on each?
and to correct speedo, could i just get it done through the xcal 3 flash box instead of getting a speedo sensor?
thanks

I couldn't tell you about the 0-100 difference, but the speedo difference will need a jaycar speedo correcter..

the xcal can do speedo calibration but only on b series..

I couldnt tell you to be honest.
I just had 3.9's put in my ute today and while it pulls a lot harder , its actually doesnt feel faster.
Its strange.
But it does drive very well.

I put 3.7's with lsd in mine, sits on 2100 at 100km. Did make quite a difference
