| Final drive ratios 
 
 Hey guys, looking at changing the diff ratio in an 89 T3 van,
 currently running 4.83:1
 Would a 3.9 be too high?

 bigger tyres could work well, currently running std 185/14's
 1st 12kmh (or slip start in 2nd)
 2nd 25kmh
 
 Would anyone have any larger wheels/tyres that I could borrow/try.
 15"-16" 89T3.
 Thanks,Dave.

 Thanks Rob, falcon rims should be easy to get,do they require longer studs.
 They fill the wheel well nicely and will give me the revs I am after. What sort of speed sensor do you run.
 Thanks again,Dave.

 You drill the steelies or get them done somewhere? If you did it, how? and if someone else did it, what sort of cost?
