Thread: D4 on 35"?

It is possible to run these larger sizes using LLAMS, IID tool, Rods or some other means to lift the body away from the tyres. However if you have some sort of problem which causes the suspension to drop to the bump stops the tyres will be touching either the chassis (D4 front especially) or the inner guards (body seams on a car with rear air) and you may not be able to proceed without fixing the problem or using something to isolate individual air struts and pump them up.

If you are moving along at 100km/h and your suspension lowers you don't have a lot of time to pull over before things rub. Driving on the bump stops is pretty uncomfortable but it least with smaller tyres you are driving.

This is not to say you shouldn't do it. Just be aware of the risk, having had both my previous D3 (a dodgy height sensor) and my current D4 (my fault) lower at inconvenient times in the past I decided it wasn't a risk I wanted to take.

While I agree that 35s could cause some major issues

In my case, I ran my 275/55R20 around town without any lift for 2 weeks with only minor rubbing on full lock.
I raised it when I arranged for a full wheel alignment.

Tyre comparrison.JPG So an overall height diffrence of 1.9 inches and 0.8 inces in width or effectively 0.95 inch above the tyre under the wheel arch and when turning, with 0.4 inch inside the wheel arch and 0.4 inch towards the outside. If the suspension goes, it a flat bead back to the shop with or without this difference.

Well it could be done, look at this current RRS on 37" tyres!

I do love that! Just reading a previous thread on it, they basically lowered the front and rear suspension assembly by 6".

Getting that passed by an engineer would be a challenge I'm sure, let alone pay for insurance for it.

It'd be an interesting exercise. From what I can see it is a suspension lowering job (Like the Les Richmond Disco2 4" kit) rather than a body lift. Speedo correction. Those tyres would need to be covered though.

That winch is in a strange place.

Correct, it lowers everything by 6 inches front and rear, they guy that built the lift(drop) has been doing the same to hummers for years.. Awesome end result, just goes to show you anything is possible

Does the entire D3/D4/RRS suspension mount entirely on sub-frames for the front and rear? Is the top of the struts also to the sub frame or does that go to the body?
