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)

I have no preference green vs orange for a street car, as long as they don't get mixed. For race cars I use distilled water and Water Wetter. For HPDE you should be OK using antifreeze on track - OK with NASA, FWIW.

The LG radiator looks like it will work for you.

Is there room with your headers for the Mocal pan mounted thermostat? In the pic of the AR headers it looks like no.

If the Mocal piece does work, you don't need the $450 LGM kit - you just need 2 lengths of -10AN hose of the proper length and termination. A local race shop can make them up for you.

If the Mocal piece does not work, IMO your best choice is a remote filter and thermostat like the one I linked - pushing the oil filter lower with a filter pad adapter may make it the lowest point on the car, and vulnerable to damage. I like using a real, manly sized oil filter anyway.

I would run a 170deg thermostat, at least.
