Can you explain that statement a bit more? what was it about the larger tyres that reduced your traction? or is it the impact on the gearing you are talking about?

Gearing and Power : I had accepted a slight loss of power with the 32's and the tdi - however I seemed to notice it off road more with the tru tracs installed. If I was going to be off road more ( I like how the tdi runs on the hwy with 32's - a comfortable 2250) , I'd go down to 30's. Just a personal opinion.

One of the little mentioned benefits are that when going downhill in low range the car used to push through the brakes, only choice being to drop it into neutral, then it would lock a wheel and slide on down the slope.
Now all I have to do is leave it in neutral in low range ( as a back up ) with CDL engaged, nothing locks up, progress is slow and controlled and the brakes are not pushed beyond their limits.
The other benefit is that I have been able to retain the standard axles etc, as I no longer have to rely on momentum, all is good to date.
As mentioned in other threads, if a wheel is lifted a small amount of left foot braking will keep drive to the wheels on the ground.
I got mine from Bill at GBR 12 months ago for AU$1100 for the pair with bearings and a mate fitted them for another $200, at that they are awesome bang for your buck!

Mate you got a lot of talk about being in neutral when your offroading

I hope that's a typo!!

As for the original poster I was going to put TT in the front and the rear of my 300ti auto however I decided to go Detroit rear and TT front (was cheaper too got mine 990bux delivered from the states when the dollar was high) I run 245/75's an they work great.....

you can see a bit of video at the bottom of my post from our off road trip yesterday at Ourimbah..I never would of made this climb without them.

I agree with dullbird, hope thats a typo, otherwise what the **** are you doing in neutral offroad, i learnt that lesson riding down the bank of a dam on my XR70 when i was little (luckily away from the water).

I'll mention here that a V8 AUTO in low range DOWNHILL, WILL push through the brakes enough to become a real concern. In my RRC before I fitted the Diesel I had a 4.8litre stroker engine, big chip etc etc and 33" tyres. In low range descending a slope ESPECIALLY reverse, it was very, very dangerous. A few times I did have to select neutral to control the vehicle. I was even more convinced a Diesel manual was a better option after a few hairy rides


I can understand why he does it, but I don't agree that it should be best practice, AT ALL.

Justin I'm not saying that V8's down hill aren't shocking we had one and they have little to no engine braking causing you to be on the brakes a lot but Ian got around that by power braking on steep slippery slopes..I'm not saying that this is best practise either but I think taking the car down in Neutral is dangerous...

I just think things can go bad quickly (especially if panic sets in) and if in neutral and you start to slip sideways you then have no control over the car.

This of course is just my opinion and not an attack on foxspell I was just shocked to read what he wrote...

Too right!! Thats why I stopped doing this, I avoided situations where I had to back down a slope and as I said that convinced me to swap running gear. An auto is not the issue mostly, it is just that my engine was built more for performance than crawling , with the cam it had it idled at 900rpm, ( stepper motor controlled) so with its low end torque it would just take off

You fellas have obviously never enjoyed the pleasure of trying to slowly walk a v8 auto D1 down a steep slope, you keep one hand on the wheel and the other on the gear lever, ready to shift into drive if necessary.
The other option is to have it in gear, two feet on the brake pedal bracing yourself by pulling against the steering wheel, it can be that bad.
I have new calipers and bars fitted.
