Is there a deterioration of performance in either of the modes (comfort, normal, sport)?
Wondering what (if any) are the down sides of doing this.

Thanks.

Really? I would have thought it may have some added rigidity/lower mass for in corner stability but looks like not.

Wow.

Jasonsowners, is your 05 CTT even lowered? I find it hard to believe why fellow members spend up to $3K on a lowering module on their Porsche for it to ride "like ****. looks ****". Come on now. Seriously. Please do not mislead other members.

Screw you guys and your lowering

I'm sure I could tune my lift with the same process.

So my assumption was that after lower (to a point), an advantage would be seen in handling, even if some concessions would be made in comfort.

Can someone chime in and help provide more detail here?

If handling is degraded, why?
If handling is increased, why?

Lowered center mass of a vehicle is always a desirable thing at the track. Trying to understand here and get some real data as I was starting to consider at least do this DIY to get mine lowered (not to max, but to a decent acceptable level to my liking).

Thanks again.

Do I spy cowboy boots in that pic! By the way- Yes, can raise the suspension using the same method. Just lower the values during the process.

At one point, I decided I was going to do this during the winter for added snow clearance, then lower it back down for Spring. Then I realized that it would be too much work

In the simplest terms it's all about the suspensions ability it control the bumps in the road and weight shifts of the vehicle.

Think about a "Radio Flyer" red wagon for a second. They have no suspension at all. So what happens when you try to turn one quickly or pull it up a curb? It tries to fall over and lift a tire of course.

It's possible to lower the car to a point where it actually gets the Radio flyer effect because the suspension can't travel far enough to be effective.

On a vehicle like the Cayenne with air suspension Porsche is able to give you the lowest possible setting they feel is still good for handling. Other cars without an adjustable suspension must compromise between usefulness and handling. Where lower might be great on a track but won't Lear speed bumps.

If I were to lower mine I wouldn't go any lower than the GTS/CTTS factory setting.

Very simple - small degradation in comfort since their is less suspension travel. For me, I viewed this as "tightening" up the suspension since I thought stock was too floaty for my tastes. I contribute the stock CTT ride quality as to why many people contribute the GTS as the sportiest in the Cayenne lineup.

Better handling / less bodyroll / more effective PDCC control since it has lower center of gravity.

You can witness this after I post my upcoming autocross video next month.

FWIW, same CTT with the summer wheels on.

I'm actually considering selling these and just running the 265/65/18 all year long.

Yes. Mine is lowered with the Techart ecu. However, I didn't know for sure until today. It came with the truck. So I don't have a stock CTT to base my experience off. I was talking about a lowered tReg. Which I am assuming would be about the same. I can post pics of it sitting on the bumpstops if you would like me to. Here is one.
