The dealer tells me the bumper cover is $1,431 and I also need these parts for another $1,700:

Lip
Grills
Bracket for Radiator
Air Ducts
Two hoses with changed fittings
Modified Reinforcements

I want the OEM GT 2 part but can't see how it can be another $1,700 for other parts.

What parts do I really need? Is there a DIY? How many hours does it take?

 

I had a similar idea a few months ago when my front bumper was damaged, but the GT2 bumper was quoted as around $4000, and on top of that the dealer said Porsche would not even sell it unless you happen to have a real GT2.

 

There are a number of brackets and custom lines etc to do it properly. The front radiator should be angled and this changes most of the structure and surrounding supports. There are ways to hack it, but I suggest the right way.

 

Here are some of the OEM part numbers required to convert to the GT-2 front bumper.

996 504 195 30 console upper
996 504 679 31 spacer sleeve x2
996 504 413 30 console lower
996 575 141 30 center air duct
996 505 563 01c air inlet
996 505 564 01c air inlet
996 505 561 01c air inlet

996 106 538 72 hose GT2 center radiator hose
996 106 439 72 hose GT2 center radiator hose

 

does this in any way increase aerodynamics or cooling?

 

I'm undertaking this project with Stephen/Bob's help later on this month... It certainly changes the way your radiator's cooling works that's for sure.

 

I believe, the GT-2 upgrade, will add additional downforce on the front end, due to its, flowthrought design,..i.e in throught the big-mouth, and exiting through the new luver, installed on the front of the hood. Aerodynamic drag may be less..as well with this upgrade!

 

Both -- from the GT2 Product Information Book -- "The contour of this outlet (referring to the outlet located ahead of the luggage compartment) is designed to create a vacuum behind the forward-tilting radiator. In addition to increasing the throughput of air, this feature prevents air from passing underneath the car, thereby eliminating lift on the front axle..... As a result of these modifications it has also been possible to dispense with the left-hand radiator fan, thereby reducing overall weight of the car while improving the throughput of air."
