I do about 15-20 days of DE/yr. My car is a 05 C2S. Suspension parts have been replaced with ERP, Tarret and GT3 control arms. Eibach springs lowered car about 1". PASM box from TPC with three settings instead of two. Shocks are stock.

While at Pocono on my way to 150-155 MPH the front end of the car got scary light. Felt like I had no steering. Going up the Ss at WGI car gets very light cresting the top. Need to breath the throttle or I won't make it.

Here's my question. Thinking about putting a Porsche Aero package on the car. I don't like the way it looks, but if it help on the track, I'll live with it.

Does it really work or is it just for show? Other Options?

Thanks everyone.

 

It's not for show, as it was designed by Porsche to add downforce to both axles. Well... definitely reduce uplift of the front axle and add downforce on the back via the wing (which provides directional stability, too, not just downforce).

Couple of posters running at the track did upgrade to Aerokit and noticed improvements... but darned if I can find them!

The Porsche factory Aero totally works. I love it. On the track I notice a difference not only with front end float but a more stable rear end.

 

Front splitter would help enormously.
