How much benefit of downforce and negative lift does the porsche aerokit provide over the stock set up and at what speeds does it actually affect the driving dynamics. Tom

 

I didn't know they had a aero kit for the turbo

 

they do have it now, but I doubt you would notice a difference in driving dynamics unless your on the autobahn at 120+ all the time.

 

found this pic for you ..it shows they do test their kits in wind tunnels ..this is type 1 kit i know they do auto bahn super high speed test on the GT street kit ..techart is all about high speeds ..... sorry i tought you said techart my bad. ...not oem ..oops

 

It's option XAF in the '08 Turbo Order Guide. Price $6950.

Includes new front spoiler lip, new engine cover with rear spoiler
and fixed wing profile. Paint finish in exterior color including
standard side skirts and standard lower part of rear apron.

Note: substantially reduces entry angle to gradients.

 

I don't expect to be a notable difference...

 

I think you will pick up more performance from your wallet being lighter vs. the aero benefits. This is pure profit for Porsche, frankly its ugly too IMO.

 

This is my opinion too, wraped in a very funny package. Good one

 

I don't much care for the factory aero kit. Little boring.

 

Is it really worth all the cash?
If you want a new aerokit I would go for the techart one.

 

Agree. I can think of a million other ways I'd spend that money.
