Vz clubsport diff

[Cammy11220]

Hi guys. I have a 2005 vz clubsport r8 automatic. It has cam and heads done and is dyno tunes at 400 whp. I am looking at putting in a new diff and am wanting to know what ratio to choose I’m looking at the 4-11-1 but I wanna know the fuel consumption and revs at 100 kmh and if another ratio would be better. And what model diff to get. Cheers

4.11 would be way too short with an auto mate 3.7 would be the way to go in my opinion

Heads/cammed 6l so now you're concerned about fuel economy

No stally?

The difference is a few hundred revs so look it up on speedo/gear calculator.

If doing plenty of highway go 3.7 or if weekender you want to race & feel quicker 3.9-4.11.

Cheapest would be getting 3.46 manual diff,swap it yourself then get speedo fixed up.
