Diff Ratios

What diff ratio options are there? currently running a 4.0-1 diff in my Autougrass car but finding it too low geared. At the end of the straight I'm touching on 7000rpm, could do with less revs. Thanks for any info.

[quote=p fandango;509016]don't you mean M56LK[/quote] Hmmm i am doubting myself now. It isn't the 190mph odd box as it is off of a c70 t5 I can get wobbly to check as box with him

Looks like a 3.77-1 diff would be better, 10mph quicker, so would reduce the rpm. Only really looking for a diff, anyone have a diff for sale?

Sorry mate I thought u meant different ratios, instead of and actual diff box

No problem Bubba. Looking for a spare diff to try, and maybe a spare complete box. Gearing seems fine, but a tad low, got the biggest tyres on I can run, so only option is a higher ratio diff.
