The benefits of Durametric lowering work great to an extent, but beyond 15-20mm lower and the ride quality begins to suffer. More aggressive suspension rebound on freeway transitions and overall harshness occurs. I'm curious, do lowering modules by various manufacturers perform the same exact task of simply reducing the preset ride heights only? OR do they also adjust dampening, rebound and other parameters that allow for a soft ride at lower heights?

 

I'm no expert by any means on the subject, but from my little bit of knowledge I believe the modules perform the exact same function as the durametric method. Only upside I know of is that the modules can be set to have the car "extra low" when parked so it looks better in parking lots.

 

you can do that from factory, its called loading level. whether you do links, module or durametric, the end result is all the same. none of them retune dampening/rebound. you're basically changing the ride height by tricking/changing the values, whether electronically or mechanically.

 

Right, but I'm not aware of any way to have the car automatically go to loading level when turned off in stock form. At least one of the modules I've read about does drop the car to the loading level whenever it is parked/off/locked.

 

The problem I see with that what if I'm in the snow or worse off-road and the car lowers down to loading level and Fs up the undercarriage.

 

It would not. Snow is soft and mostly forgiving. There is no way it could damage anything under your Cayenne while simply sitting there parked. If it were thawed and refrozen that hard, hard enough to do damage, you would not have been able to drive on it without feeling like you were driving on rocks and boulders. A few inches of something like that might be possible, but I have never experienced that anywhere near half a foot deep/high in all the far north snowbelt places I've lived.

 

Just get the links for 200 and call it a day. Those are waste of money.

 

Lots of misconceptions here. The Techart lowering module will go lower than "loading mode" on the stock module, as with other lowering modules. The Techart lowering module will not automatically lower unless it is in "low mode". Anything higher and it will assume you need the ground clearance and will not bottom out.

Allegedly, the Techart lowering module increases the damping factors over stock. I did notice much of a difference. So if they do increase dampening, it may be difficult to perceive by some. Unlike the lowering links, the Techart module will not lower your highest setting and will in fact increase the highest setting by about 15mm (if memory serves)

OP, any other questions?

 

I have the Techart module, and to further elaborate, it IS possible to park too close to a parking lot concrete curb stop and have the front lip hit the top of the curb while lowering. Since the air suspension deflation begins only upon locking the car, it is easy enough to quickly check on the front end visually before walking off. If too close for comfort, it is simply a matter of unlocking the car, and the lowering automatically stops. Then up to you whether to backup the car a few inches and/or raise it to normal height, which would then disable the lowering while parked feature.

 

I got mine for $130 shipped from the UK.
