I set mine at the original spec ride height, and it looks higher than any of these pictured. I'm measuring to the suspension pads per the WSM. For some of the cars pictured, I'd be tempted to re-measure now that the cars have settled a bit.

Keeping track of ride height is important for maintaining wheel alignment settings. The factory height recommendation supports minimum toe change during normal suspension deflections. Lower means more toe change for any given compression deflection. Your target might be "the height it was at the last time I had it aligned" to help with tire wear. No matter what, it's important to keep written records of the height so you can come back to it later as the springs droop.

 

Hi,
I installed Bilsteins and the front popped-up to about 28", which looks bad. Porsche workshop manual states that 27" is max front ride height. The rear Bilsteins are perfect. Front measurement was taken from the lip of the fender well to the ground. Bilsteins are adjusted all the way down. How can I lower the front ride height? Thanks!

 

Have you driven the car at least 100 miles to let the suspension settle?

 

DCD you need to take your measurements from the lower suspension pads,
using the fender edges isnt how the correct measurements are taken

 

Using the fender edges is not accurate, but 27" is way high regardless. Another inaccurate technique that still gets a useful impression is fingers between the tire and fender lip. With correct tires, 2 to 3 fingers is about right in the front.

It's hard to get to the factory front ride height measuring pad on the ground. It's in the middle of the lower A-arm rear bracket, obscured by the outer walls of the bracket. Alternatively you can meausre from the ground to the lower edge of the rear wall on the bracket and add 10mm. That's hard enough to do on the ground. This picture shows the factory pad (black arrow) and the alternative lip edge (red arrow).

 

Thanks Bill, I need to check the Strosek, it is very low.

 

Height measurement assumes you have a stock overall tire diameter in the front (24.7"). Looking at 225/45/17 tires the height varies to 25".

If you are running 2 different sets of rims/tires that are different overall diameters this will change the height depending on which one you are running.

Guess the best bet is to check the height and have it aligned with tires having a diameter of 24.7" to 25".
