I want one that will work with the larger GT3/GT2 brake ducts...

 

I'm relatively new to the 911 world. But from what I saw, no vendors seem to offer a reall effective splitter. Even Porsche own GT3RS offers only limited downforce. It's not really part of Porsche game apart from the cup cars that have more effective parts.

On my previous car (Lotus), I made over 300lbs at 100mph, on a 1900lbs car. That was something you could feel and use. I looked at what was available from Porsche vendors and nothing will get you even remotely close to these levels of df. That's really sad because df is addictive and is almost like cheating when you really have a nice working set up.

If you want front down force, the best way is a stiff, long, solidly attached splitter. The only thing I found that should work is this: https://www.6speedonline.com/forums/...ng-classy.html

You should also consider adding a pair (or two) of front canards. I haven't seen anything for sale for Porsche, but APR sells generic ones that fits any car.

If you go crazy with front down force, you should also consider going equally crazy with rear down force. I assume you already know that. If you don't try to hit downforce bias front to back that will equal static weight of the car (35/65). Otherwise you will greatly affect car dynamics at high speed. In which case you better know what you're doing or things can get ugly.

For those interested, there are a few good books on aerodynamics. I love the one from Simon McBeath.

 

Scott, check out this link. At the end of the thread there is a guy working on an aluminium splitter that may work out to be a reasonable price, at least that is what I am hoping.
