I took my daily driver to a little road race practice course today. Each lap was only a minute and I'd stay out there for only 5-10 minutes. The first session I just wanted to work on tire temps, then I let it cool down. I actually logged the second session and have some questions.

Water temp: I live in Florida, so I run 100% distilled water with maybe 1-2 bottles of water wetter. After 7 laps, I noticed the coolant temp was at the 3/4 mark so I brought the car in. The scan tool later revealed the temp had peaked at 244*. Isn't that a bit warm? Solutions?

Brakes: In the front I have standard C6 calipers, Trackbrackets, DTC-30 pads, new standard C6 rotors. In the rear I have Powerslot rotors and HPS pads. All stainless lines and using SRF fluid. While it didn't have a problem stopping, the pedal became easier to depress and started grabbing hard closer to the floor. I didn't like the feel of this, how do I remedy it?

The log also shows it was pulling 4* of timing on all WOT sections. I bet I have a knock sensor code (IMG:http://www.frrax.com/rrforum/style_emoticons/default/mad.gif)

Alan - So you're saying that although the air dam was installed since the day I bought it new, the air dam wasn't forcing air into the radiator because of the ground effects (installed by GM at the factory)? Or it wasn't forcing air into the radiator because I later removed the baffles?

If I recall correctly, the OEM front ground effects use rivets and hangers to attach to the bumper. Having removed most of one on a autox cone and the other original manually to make it match, I can say they don't come off very easily, and don't re-attach very easily. When I was in a later accident I had new ones installed. And the car looks like complete crap with part of the ground effects package missing. I won't choose to remove the ground effects again unless it becomes a dedicated race car - but I would be interested in replacing the front ground effects with something like a hard rubber vertical piece so when it scrapes it won't change color. It would need to look decent on a street car and also have the desired functionality.

In this photo you can clearly see the air dam below the ground effects :

Photobucket is causing me grief getting a couple photos up, but here's one from the front showing the air dam is not blocked:
