35" on a GU??

Post by **GUJohnno** » Thu Jan 15, 2004 10:34 pm

I have a 3" lift on my Gu III (the rear is more like 4" unloaded), and was wondering what, if any trouble I would have if I put on 315/75/16 (35") tyres on?? Anyone done this with a 4.2 TDi and how does it perform?? And how much does it affect the braking??

take a trip out to Procomp at Narre Warren see if Locky has a set you could try.

I was there today getting a second hand 285 to replace the one I wrecked a couple days ago (2 tyres in 2 days). Hobsy will do a great price on 315 X-Terrain. Locky says they'll fit, remove the front mud flap, slight rubbing on front at full noise.

I have a mate who was running 37" mtr's on a GU with 4" springs, no body lift. Slight trim of a little part of the inner guard and no rubbing at all.

Just removed my stabilizers today and did Rocky Tk and a few others around Toolangi. Happy with the flex

but quite a lot of rubbing on both sides with 285's. Hobsy measured the off-set of the alloys against the RockCrawler rims I'm getting and there's 17mm diference (R/C rims 17mm further out). Still think there will be a bit of rubbing, thinking of spacing the rear bump stops down. What do you recon :?:

If you are intending to run the factory steel wheels then you are likely to get rubbing on the inside of the rear guards (wagon) or chassis rails on a ute.

Clearance wise there is heaps of room - I drove my ute home from the dealer, threw a set of 35" claws on and took the original tyres straight to a friend who owns a tyre joint and had enough clearnace with no suspension mods (on road only of course). The brakes are average with the 35"s and after the first time out you will probably decide that you want to put lower gearing in. On a 4.2 the 4.625s bring the gearing back pretty close to normal but it is an expensie swap if you decide to go factory ring and pinion gearing.

With 4"springs, 2"body lift and a heap of inches cut out of the front guards at the rear I have no problems running 38.5"Boggers on custom offset wheels so you should have no worries with the 35"s.

Wont be running standard rims will have the RockCrawler rims. It should be fine with the bumpstops extended and I've noticed BigBalls have a bush kit that push the front diff forward somewhere around 12mm. Anyone done this and does it much up the geometry of the front :?:

The spacers are more to allow clearance on the front wheels to the guards.. Common mod on GQs

You shouldn't need the spacers if you are only going to run 35"s. Even with the factory steel wheels and a set of Claws there was no interferance but step up to 38's or bigger and you either go the spacers or (as I did) grab the tin snips, a heat gun and a rivet gun, close your eyes and start triming the rear inner and outer guard.

It took ages with the heat gun to stretch the factory flares but I can now run 38.5 x 11.5 Boggers at full flex with no rubbing on my GU ute. And the best thing is that unless there is a standard GU parked next to mine with ARB rails on it, you would never even know that about 4" has been chopped out of the rear of the guards.

I run a 3 inch lift with 35 inch claws no body lift & no cutting on the GQ. Rubs little on the inside with cruiser offset rims. Surprised me when i put a mates 35's on to see if they would fit. YOu shouldnt have a problem with a gu as they have more room. (a mate has one with 35's on his

Cheers

you got 35" claws under a GQ withou cuttin or bodylift, how, i can only just fit 33's under my GQ with 6" springs real close to guards but only rubs inners

Im in the same boat Ozy! 33s rub on chassis, on lots of compression.

When I put the 285's on I had to space out the spare on the door by an inch so thee was no rubbing. Was worried about how to carry the 35" as not enough room from the rim to the rear bar. Bought a bracket from ARB (made by Kaymar) that not only spaces the wheel out 1" but raises it by more than 2", cost me $72.00. Good price, neat finnish and has brackets to suit a rear light. Managed to also get new RHS section of rear bar (worth $500 from Nissan) for the price of a slab!!!
Got to be happy with that :lol:

What is the largest LEGAL size that can be fitted???

all comes down to Rims, 8in wide is the widest you can run on a wagon, so 12.5 is it, but that depends on what the manufacturer will back..
If you can find an engineer to do 35s that would be about it, although Wendle has his done with 37s in Canberra.

It has been said before that 4.6 gears returns the gearing back to standard when running 35" tyres. Is that assuming that you're running 4.11 gears as standard. With the 4.2 TDi the gearing (as far as I know) is 3.9
A friend has 4.3 gears and has suggested swapping with me which would bring it back close to standard (and be very cheap!!!)
Any thoughts???????

The TDI wont be 3.9's your talkin the GU arent you? I dont think any 3.0/4.2 GU is running 3.9 actually...

I have 4.1s standard, mines an Auto, Running 33's.

I've been doing some calcs on the speedo and tacho, working out that 4.6s add 600rpm to a given speed, and it will be awesome for weekender, but I think touring might suck a little..

What are your friends 43's out of? GQ they wont fit.
Ive also thought about 4.3's, which would add 300rpm, which in a diesel is a bit of difference, not as bad as 600!

But yea these 6s came up cheap...

Post by **Butt Craic** » Sun Feb 01, 2004 7:41 am

I've got a 2001 4.2TD coil cab and did the swap to the 4.625's when the 35's went on. It brings the speedo callibration back to within a bee's dick of standard.

Post by **GUJohnno** » Tue Feb 03, 2004 4:47 pm

Just picked up my 315's

Looks great

Drives great

Plenty of power to push along but revs a bit low at 60km (1400 rmp)
Friends 4.3's are out of a Gu ute
If he wants a straight swap I might go a head with it.
