D2 suspension options

**Guru036** · 18th April 2011, 05:21 PM

G'day all,

I have just bought a 1999 TD5 Auto D2 with ACE. It is mostly stock and I'm planning on setting it as a daily drive, tow rig and use for off road trips.

I am trying to decided what suspension setup would suit me best. It currently has standard King springs in it which seem to sit it about 1" about stock.

I want to run a 33" tyre and plan to fit 1.4:1 high range gears to put gearing back to standard. It seems the easier tyre to fit is a 285/75R16, but they don't seem to fit with a 2" lift from what I've read (they do with some rubbing apparently??). I like the idea of keeping the car as low as possible for stability. I really need it to still drive nice on road as it is a daily and I tow a 2 - 2.5 tonne car trailer interstate 3 times a year. How much caster is lost with the bigger lifts?

If I ran a 2" lift, How much up travel would I lose? Could I run longer shocks and gain heaps more down travel (I would have to capture the springs)? I know there are 3" and 4" lifts around, but I'm worried the car may become too tall for it's purpose (car parks for example).

Any thoughts and ideas would be much appreciated.

A quality setup should retain or enhance your travel as well as lift it.

Yes and maybe and would need relocation cones as well.

I know there are 3" and 4" lifts around, but I'm worried the car may become too tall for it's purpose (car parks for example

).
Doesnt really match with your previous desire to keep as low as possible.

You have a range of questions from comparing a serious off roading setup to excellent touring and great off road setup. If your original plans as per post, are to tour and tow with some off road mixed in, then IMO a good 2 inch lift and shock combo will be the go. Your thoughts span a big gap in cost and pupose.
IMO a 4 inch lift and 285's will be require engineering report and be a pain in the butt for towing the van (hitch height, stability)
Give a call to Shane at SUS stuff and talk to him.

Sounds like you need to seek professional help!

Suss Stuff is a good idea or try Ultimate Suspension in Ingleburn.

Ok I will try and make this abit clearer.

How much caster is lost for each inch a D2 is lifted? I read somewhere standard caster is 2.5degrees and 2" lifts bring it down to 1.5degress. Does this mean with a 4" lift it drops to 0.5degrees or possible starts going negative?

I want my car setup to be able to still drive nice on the freeway towing a buggy on a car trailer, and not wonder all over the road, especially when braking

My prefered setup at this stage is a 3" lift, with 285/75R16's. But with a 3" lift I know I need to lengthen brake lines and ABS lines and swaybar rear links. But I'm worried I will lose too much castor.

But If I run a 2" lift with these tyres how much up travel would I lose to stop them rubbing in the guards?

Is my worst case option to run a 2" lift and 265/75R16 (32") tyres?
