What's the top end like using this combo?
I know the acceleration would be pretty nifty but any1 with this combo wish to share their experience?

Cheers :)

I'd like a 3.64 and I'm using a M42 'box although I have to say the 3.91 feels a lot better since i went up to 50 profile tyres from 40.

I'm running the m42 box with 4.10 ratio for now 8O lol, only for a week or so when I can afford to buy the lsd, I'm toying with 3.64 and 3.73 tbh, obv the .73 will give better off the mark (which is what I'm after)
