xpost from rennlist.....just looking for additional input.


First....I am planning to lower my CTT, however, I wanted to get some ideas / thoughts / experience from you all.

Assuming the Porsche manufacturers delivered their cars to operate at an optimal level, I am curious as to the 'longterm effects' of lowering the Cayenne.

My initial thoughts....I am a novice wrencher

The cayenne cannot be driven at loading level, which is not as low as some lowered Cayennes.....is it reading too much between the lines to think that they (Porsche) don't want you to drive at that lower level since it would put undue stress on the drivetrain.....transaxle ?

Is there anyone who has logged significant milage with their lowered Cayenne that was subsequently aligned properly......any notable effects......any pre-maturely worn parts......any need for more frequent cardan shaft replacement ?

 

You CAN drive the Cayenne @ loading level. If you put it to LL and screw in the air compressor hose it will hold loading level while you drive.

I have driven the Cayenne a fair bit this way and while the handling is amazing, it's probably not the best idea. For sure it's going to be hard on the suspension bushings as they are not meant to be rotated that far and cycled. If you were to lower the car to loading level and loosen all the suspension mounting bolts and retighten you might be able to overcome this. I believe that it is super hard on the axle CV joints due to the articulation angles of the axles and the amount of torque going thru them. The driveshaft(cardan) is irrelavent as the rear third member is fixed being an IRS and the driveshaft is not required to articulate.
