Thread: Want 35" engineered on my d2 what to look out for

It used to be that way here in WA before they adopted this NCOP VSB14 too. They still have not even agreed to the combined 50mm lift and 50mm tyre increase without engineering yet like most of the other states that have joined this rubbish NCOP yet, so I'm up against a wall of red tape before I start.

Here, we have to write in for approval to modify listing the changes in detail that we wish to do, the DOT then approves or disapproves your application. If its disapproved, no engineer will even examine your car.

The problem is that if your app is outside of VSB14 guidelines, it will be rejected.

If approved, then you trot off to your engineer of choice and if you pass, you get final approval from DOT.

So in a nutshell, 100mm offset is outside the guidelines and won't even be looked at.

And I was complaining about NSW.....

That's is a pity and not how it works here in NSW (luckily)

I better get my 35" engineered before they change it here to....

As you point out, 35" tyres are a 3" larger radius over the standard 29", giving 3" more ground clearance and pushing upwards a further 3" towards the body.
A 3" suspension lift should even out the 3" increase upwards towards the body.
An aggressive flare setup requiring the guards to be cut (such as Les Richmond Automotives Stage 2) should accommodate the extra width of the larger tyres which catches on the sheetmetal of the guard.

Likewise 33" only requires 2" of suspension lift when fitted with flares and guard cuts.

Damn you Scott, I was happy with 33s, now I'm measuring up to see if I can get 35s under a 3" lift!
Seriously, will they fit on +32 offset under 3" lift without rubbing on articulation? Obviously with guards cut and LR flares of course.....anyone?

Likewise.

I currently have 33" (285/75R16) tyres with 3" suspension (40mm coil springs, 10mm coil spring spacer and 1" suspension dropper kit). They fit and clear with no issues.

This weekend I will start to fit my Les Richmond Automotive Stage 2 Flares ( http://www.aulro.com/afvb/discovery-...-pictures.html ). "The flares protrude off the existing alloy panel by 80mm and increase the opening by 120mm front and rear and 70mm off the top."

So, I'm confident that once the flares are fitted I could take out the 1" suspension spacer kit and go back down to just a 2" suspension lift with the 33" and no clearance issues.

Alternatively (and this is my preferable plan) I could retain the 3" suspension lift and increase the tyre size from 33" to 35". The 2" tyres diameter increase pushes the tyre out 1" all around. if the new flares are opening up the arches by 70 - 120mm there hopefully shouldn't be clearance issues on the guards.
It seems somewhat logical, 29" to 35" tyres is an increase of 3" radius, so a 3" suspension lift should compensate for this and the LRA flares should cover the increase in width.

With sticking with the +30mm rims, I'll need to check clearance on the radius arms and a few other things which I'll try and have a look at over the weekend...
But an interesting article is http://www.4wdaction.com.au/articles/2012/two-tough which shows a Discovery 2 with 35" tyres and they look to be fitting underneath he LRA flares...

I just checked the space I have and that is nearly a hand width to the radius arm at full lock so will be reducing my steering stops quite a bit to give me better turning circle. Also will have no issues with 35" rubbing which is good

I just read that article and the guy has +6 rims, but reading Steves post after yours, he says he has a hands width of clearance from theradis arms on lock, so hopefully your rims will clear....I'll be interested to see how you go mate.

The +32 rims and 33 x 12.5 tyres on mine clear the radius arms and come to within about 10 - 20mm of some of the metal under full flex and I do have LRA flares and all the cutting that goes with them.

Having said that, I do not have bumpstop extensions and my suspension still has the same maximum up travel as the original suspension but a lot more drop than the original.

Is there much advantage going to 35's with bumstops limiting suspension travel and only 25mm more diff clearance compared to flexier suspension on 33's with lockers and more wheel travel???

I had thought about 35's myself but have decided to get the most out of my setup on 33's, next step is 12" travel shocks and from what I can tell I should be able to get close to using all of that travel.

I think you've asked the million dollar question Chris......truth is I don't know. However, I am sure that there will be arguement from both camps

I do prefer the LRA suspension though, so I guess the 35s are my choice because I will be stopping some of the flex compared to yours, the reason being I'm going to stick to air susp instead of the coils in the rear....this suits my purpose better, and yes, I've read all the fors and against arguements on that too, and there is very valid reasons for both sides in that one too.....decisions, decisions, decisions.....enough to send you mad

Cheers mate,
