Outer Limits 4x4 Board

Are the 6.1 transfer gears to low for 31" tyres on the highway in high range, how do they perform at 90-100 kph ( in a 1.3 sierra). Also does low range limit the off road use to rock crawling only , I figure 20 kph will be reving its head off in 5th and hi 1st may be a little high in mud and sand ?? Any body using these gears for general on & off road use with 31s????????????

I dont thing they are too low for use with 31's - but you will definately be throwing some more rev's though the car to get to the speed you are after.

As for the use offroad - you are correct - there will be situations where the gearing will be too low for what you want, and you will have to switch between high and low range more than before, but at the same time - this is a better scenerio then having to drive up obsticles slipping the clutch isn't it?

Plus, an S3 will set you up to be able to use bigger tyres in the future without having to upgrade your gearing again... An S1 will only do this to a lesser extent.

and I don't trust S1's, seen too many break, christover

I've got 28's and a S3.
It is too low for highway driving. But if you still have stock diff ratios the s3 shouldn't be too bad on the highway.
I also find myself switching between high and low range offroad more often.

ok that would be a little too low. 31's are fine with the s3 I cannot remember exactly but you are still well under 4g at 110kmh. but I must admit it does feel a lot better all round on 33 - 34" tyres

do you mean that this is what the speedo would show, or is this the actual speed?

i had s3 gears on 26s and it was screaming on the freeway
90kph was about the most i could go
it was fun dragging cars and zipping through traffic though

when i went to 34s and it was just about right again

i could live with 31s and s3 rockhoppers
redzook used to have that combo
