* The Shelbys sounded sooo good! (302 in both I heard)
* The plum miata has an LS1 in it along with good brakes and I cant remember if it had a cage.
* The red STi had minor upgrades, tune and street tires - did very well.
* The green/yellow Exige kicked major ass. I think it was stock. I wish I had numbers to post.
* The orange mini got too agressive early on when it was cold and had a skirmish with a tree - it lives with minor wounds.
I talked to the Red vette's tuner - he didnt say anything about oil temps but the brakes were definitely not track quality. The owner spent money on a cam, and other stuff - but the brakes were stock...and fading fast lol.
I dont know much about C5s but C6's will burn oil if you put in the "recommended" amount of oil. At the track, you need to run less 1/2 quart less than you do with regular street driving or it'll get into the intake - and screw things up. Its pretty weird.
