Below freezing at the track
 

I'm heading to VIR tomorrow and the weather forecast is calling for an overnight low of 22 degrees. I'm a bit concerned about the low temp and my lack of antifreeze in my cooling system and freezing of my slicks while my car is parked over night. Any suggestions?

Put in antifreeze.

There have been a number of posts alleging that slicks get damaged if subjected to temps below freezing. Would be interested in your observations after running

oh boy

Its an issue on both fronts. Motor could freeze and slicks can crack and the molecular compound of the rubber changes.
Find out if they will have the garages open at the track and if there will be any heat

You may have the same problem we do in the West. We tow a long way and it is colder in the high mountains - it is not uncommon to see single digit temps overnight in late February or early November, even if the track temps overnight are in the high 30's! The most recent issue that I had last October and a cold snap occurred and my return trip from California was going to be towing through 6 hours of 15 to 20 degrees. I decided to add Anti Freeze to my cup instead of risking freezing a radiator or worse. Even in an enclosed, insulated trailer it wasn't worth the risk.

sorry if I seem out of the loop, but why would you run water in your cup over anti freeze?

Antifreeze is slicker than oil when spilled on a track and harder to clean up, therefor most tracks and racing body's in the US ban the use of antifreeze.

I strongly recommend consulting your tire manufacturer and distributor regarding viability in cold temperatures.

Keep the car up on the air jacks and don't drop it abruptly in the morning. When you start driving it, stay off the curbs for several laps so not to cause cracking from abrupt hits. After several laps, check pressures. If they have climbed, good chance tires are good to go! Do Not Put Anti-freeze in the motor as you will have to drain the system before any race. They don't like ant-freeze on the track and nor will you by your back tires. Normally the additive they recommend for the track will drop the freeze point and lift the boiling point enough to get you by. Keep the car covered and likely you will be fine.
