After fitting my GT2 fronts a few weeks ago I fitted the rears yesterday. This is what you get in the kit, the part numbers (L&R) are 996 331 127 90 and 996 331 128 90.

I found that the left one was a bit of a battle to fit where as the right one went on really easily. However for both I found that when your wheels fully hang down the end of the spoiler touches on the cross brace under the car:


So I went about filing a scollop out of both so this didn't happen. On the road it wouldn't be an issue, but when you put your car on a 2 post hosit it would stress the plastic and either crack them or pop them off the brackets


You slip them on the arms from the front and once I got them to fit nicely with the suspension hanging down, you slide the bracket on from the back and insert two expanding nuts from the top through the duct and the bracket, and one from the rear.



And then you are done. Whenever I pull my rotors off I will trim the backing plate to allow more air to go directly on to the back of the disc.

 

Great post. I'm going to have to get me some of those

 

Great write up this is defiantly on my to do list this winter.

 

Thanks for this, I just bought a set and will install soon.

 

Installed mine last night and also used a hot knife to trim. - worked great. Fronts are huge and had to trim the pan also.

 

A timely post. I was looking for the part numbers today for the rear ducts.

 

So you also fitted rears? Did you have to scallop the rears like I did?

 

Yes indeed. A good suggestion. I used a hot knife instead of a dremel but the results are the same.



Fronts:



Have you had any issues with these touching speed bumps?

 

I found the best price at ECS - worth a look.

 

great post

 

Hi Guys,

i installed the gt2 brake ducts too. Mine fitted perfectly without cutting anything at all. Plug & Play. Now i just need to cut the brake backing plates so the air can reach the brakes.
