At what speed is aero a good idea?, New bumper for #209 Options

[Jetsetsurfshop]

Hey Paddock People,
My car sustained some pretty good front end damaged and the 916 front bumper is destroyed. Thinking this is a good time to change things up. Good news is that already bought the bumper half with the oil cooler cut out. Now I need the bottom half to finish it off.
The thought is should I run a splitter type valance? What is the speed where these cars want downforce? My car's top speed at Sebring is 115mph. I see a lot of HSR 914-6's that don't have a splitter and I know there are faster then I am.
Another thought is that I'm not the only driver of the car and when we have an off track experience, will the splitter still be there??

John - An airdam I'm not against for Shane's application and speed. I use the same airdam myself but I thought he was talking about an actual splitter. Here is a pic of my car with the same Airdam you pictured but with a 4" splitter. This slows my car down...thus my advice. The "tipping point", speed wise, to answer your question would be at about 130 mph; based upon my on-track experience. I actually lost my splitter in June and the car drove (pushed like Hell) but that was over 160. In summary - airdam would be ok.
