That looks like quite the car you have there and built to go fast and stop! I took my gtx out to Willow Springs a few weeks back and as you said track use is very hard on a car. We were told during our driving orientation that 1 mile on a road course is equal to about 10 miles of street driving on suspension parts. I know my front tires did not like being pushed and have just bought some new rubber due to tire scrub. Have never been to Watkins Glen but I did go about 115mph on the strait between turn 9 & 1 at Willow. Brakes are definitely a big deal when putting the power down and making good time around a track. Have fun and be safe. Beautiful Charger you have there!
