Tuners: 997S coil overs?

Are any of the tuners working on a coil over package for the 997S that works with the active dampers? If I get a 997S, I must have an option for lowering it!

A coil-over suspension will not retain the electric dampers of the PASM. It's a matter of discarding the "normal and sport" modes of PASM(a range of reactive settings based on data acquisiiton) in favour of a system that provides precise, fine-tuning adjustment of compression, rebound and pre-load in fast and slow events.

Perhaps you're asking if Ohlins, JRZ et al will be delivering coil-over suspension that integrates with PASM in terms of data acquisition, processing and real-time adjustment. That would be fun. I wonder how many millions Porsche spent just to get PASM to work in two modes. Will the damper makers decide to parallel that investment?

I am having enough trouble building a dynamic system with driver-adjustable controls. It's hard work! Still, once you've driven with a cockpit-adjustable system, the idea of having to get under the car (or at least stop and open the trunk and engine compartments) is archaic. We're not going to be driving with Schumi's steering wheel any time soon, but there are some treats we can take from the F1 developers that work on street and track cars.

I'm sure once the tuners have their development "mule" cars, PASM will be the "happy hunting ground" ... in my humble, the 997S technology is the next level of sophistication for tuning. There's great potential from what little I've learned thus far.

I expect to see the conventional improvements in brakes (swap out ceramics for steel or go to full-floating from the after-market companies) and power (plug-in 'interceptor' technology to tune air, fuel, timing) or bolt-on improved exhaust systems.

The potential for radical, new technology will revolve around vehicle handling dynamics -- chassis, steering suspension.

PASM will be a hot topic for the Carrera from now on.

Cheers,

Actually, I was thinking of just shorter coil springs, and/or adjustable spring perches that work with the OEM dampers. That should not interfere with PASM. PASM hardware is just the variable dampers and sensors. I've done a similar thing on my C5 Vette with active suspension - lowered it and changed out the springs - it worked fine.

Alternatively, I wouldn't mind just removing the PASM dampers and replacing the whole thing with a full coil-over. I kind of don't like the idea of PASM anyway.

Until I get full service documentation and parts specifications, I can't answer in more detail. From the operator side of the PST3, there's evidence of potential advantages in many ways. Early days. I'd have to suppose that lowering the car with springs alone might well be harmless. I'm keen to get a 997 on the aligner and play with it's suspension -- I hope bump-steer is improved.

I believe DEVEK has been a sponsor (in a roundabout way) since about February (but don't quote me on that ... and I didn't write the check ...) but thanks! : )

There are only five software modules which are superimposed over Normal and Sport mode for PSAM.
Forget about removing PASM for coilovers..you'll be getting lots of warning lights, Its way integrated into the electronics of the car.

Hopefully a US variation of the steel sprung ROW -20mm sport will become available down the road

So what? There are only 4 ride sensors that need to be fooled or terminated.
