Looking to understand why my car would have an uneven ride height front to rear with Eibach/Techart springs installed.

It has the PASM suspension, so that's already 20mm lower than factory. Coupled with the springs, it's 35mm lower total, and almost 'dumped' up front. The rear is more sensible.

Incidentally, the car was also featured on the sharkwerks site when new (when springs were installed), where it's also slightly perceptible the car is lower up front than back. After about 60k miles, that difference seems more pronounced.

Any thoughts? Any way to bring the front up or the back down to match?

Springs can sag over time. Other things could get worn too. Lowering a car can also wear out the shocks quicker too. Have a shop take a look.

There is a rake designed into the suspension by Porsche too, with the front slightly lower than the rear. Measuring points are from the floor to a bolt head on the underside. The gap at the wheel well is unreliable. The specs are more aggressive for GT3's and cup cars, and even adjustable due to coilovers. Fora stock NA 997 though the values are fixed.

With lowering springs the ride height is reduced of course, but the drop should be somewhat equal front to back. So, inflate your tires properly and measure from the factory alignment points. Then compare the front/back difference to stock values. 997.1 C2/C2S values below.

True coilovers would allow you to adjust each corner independently to get it just how you want it, but as semicycler notes, visually looking right is not necessarily right, as it's the understructure that needs to be correct, not the body panels. If you have PASM, you can preserve dual mode functionality with either Bilstein B16 Damptronics or TPC's Tractive DDA setup.

Ideally, you'd do coilovers and have a corner balance done with your equivalent weight in the driver's seat.
