Default adjustable suspension

718 GT4 suspension looks to be a coilover system, correct? Is it height adjustable? Anyone raise/lower and what was the outcome?

Yes it is height adjustable coil over from the factory. It lowers and raises just like anything else.

The adjustable ride height is there for the purpose of making fine adjustments in corner balancing when getting alignment. It’s not intended to make significant changes to overall ride height. In particular, lowering the car greatly increases the chance of punching the struts through the chassis if you hit something like a big pot hole or curbing at the track. There are threads about this (strut tower or shock tower failures)...

I always felt the rear was about 1/2” to 1” too high, in proportion to the front

That Rake is there for aerodynamic and driving dynamic purposes 👍🏼

yes definitely, All my sports cars have had a rake, and i am sure Porsche set it up like this for a reason. but the rear wheel gap is very prominent on the GT4. Front, on the other hand, looks slammed lol. Also the rear looks more flush, like it has spacers, compared to the front

THIS!!!

If you alter the front to rear height separate from each other and unequally, you will alter the handling dynamics.

??? The difference between front and rear wheel gap is only 1/8th of an inch. Barely even noticeable unless you get down there with a tape measure.

I lowered the car 10mm when I did corner balancing/alignment by the race shop. I don't have experience lowering cars, and can't compare it to factory height, but no issues so far.

i havent measured, but the difference looks greater. The rears do also look more pushed out (like when you install spacers), which will make the wheel gap more visible, while the fronts get hidden by the fenders

Yeah, I think it looks lower because the fronts are slightly tucked in.

This is an optical illusion. The rear wheels/tires are much more flush with the fender, creating the illusion of a larger fender gap. The front looks "slammed" by comparison, only because it is more tucked under the fender.

There's a detailed
from Obsessed Garage about this along with adding spacers to his car.

So what is the maximum height adjustment (Higher / Lower) you can adjust with the stock suspension?

In theory, you can completely “slam” the car if you didn’t care about the driving dynamics one bit.

Take off that helper spring, and you’d have enough thread body to have the car sit on bump stops at all times.

If you do however care about driving dynamics, I wouldn’t lower it much past 1/2” from OE ride height.
