Ride Height Adj Question/Confusion - Baffled

[Duc Hunter]

So after Werks on Friday I wanted to play with raising my car's ride height. It's bee really low, and thanks to my coil overs it rides pretty well. I was thinking a "gravel rally" height look, which is similar to a snow rally look, but below a safari. The fenders on my car are a little wonky in the rear, so I chose rot measure it "properly," meaning per factory. So when I started I measured my axle height as 310mm. The center of my front torsion tube (TT) was 125mm high, and my rear was 250mm. This means my ride height was +185mm/-60mm (i.e. 125-310=185, etc). For comparison the factory Euro Spec is +108mm/+16mm, and factory USA is +99mm/+37mm. Keep in mind the higher the front number the lower the car, and the higher the rear number the higher the car.

Anyway, that means I was about 75mm below Euro. It was low, so that did not seem to strange. Then I cranked the coil overs up. My goal initially was Euro. Well in the pic below the car is now at 179mm/291mm. That is still some 23mm/19mm lower than Euro according to the specs (i.e. 179-310=131 and euro is 108). But, um...thanks looks WAY higher than Euro to me. At the risk of making myself look like horses ass....what am I doing wrong? The car does have 935 rear spring plates, but those are in the middle hole, which to any eye is in the middle of the rear torsion tube.



For reference, here it was in the low setting.

Can't really answer the question other than to say the low setting is pretty damn low..... it does look a bit high in the first pic.

I'd say just play with it till you like it and go with that. You aren't doing anything wrong, and I don't think Euro is as low as people think.

Yeah you need a happy medium between both pics. Don't concern yourself with "Euro height" it's not like you are trying to be correct on that self proclaimed rat rod (which is awesome btw.)

The 17" wheels and non stock tires are probably throwing off measurements anyway.

I love the low setting for looks, and there was nothing wrong with it ride wise....other than entrance and egress for the passengers, and the occasional driveway. I wanted to try higher to see how high I could get it and still have a reasonable alignment, and to see if I liked the look and ride of maybe a "gravel rally car" look and feel. I know "safari rally" look is not attainable without longer lower control arms, etc etc. So I just thought Euro height should be easily attainable, within the factory alignment adjustment spec's so I good starting point, and then I would go up from there.

It seems as though I am doing something wrong in my measuring, as in the pick above I am still around 20mm below Euro at the torsion tubes, and yet my front fenders are 26.5" high (+25mm over Euro). So that's why I am asking here.......am I missing something?

I'd go down front 2cm, at rear down 1cm

You'll just have to try as your cars weight may be different from stock.

A freind tried to dial in his custom built ST that lost a lot of weight. He couldn't start with spec Settings as all of his car was off.

Take a look at these and I wouldn't get so hung up on getting it too high just 'cuz of looks:

I have seen those, and taken a lot of pics up close. They are 4” or so above stock USA. Lots os suspension work to do that. Lowered spindles, longer shocks, often a 935 style front lower control arm setup....etc etc.

The factory specs are for a car with the factory tire diameter. Taller tire, and the floor pan will be higher off the ground. The factory specs are intended to keep the suspension geometry within what Porsche believed was its appropriate range. To keep the suspension working right, in the front you would raise the spindles - 19mm is the max with 15" rims. In the rear, you can use the upper location on the plug in the torsion tube, although that perhaps ought to go with a rise in the inner banana arm mount, like the 935 setup where they are adjustable.

If you want it to ride higher, you'd go the other way.
