I get not wanting to thrash on a car you just spent years and thousands restoring. My friends Charger 500 saw a bit too much track pounding and started to twist,so he built another car strictly for the track;these unit body cars do bend if you pound em,so be sure to add in whatever reinforcements you deem necessary. For my Dart which most definitly will see track time,it will be frame connectors,roll cage,torque boxes.Should be able to stand the car on one end and drop it pretty hard without breaking it after those mods.Oh and also wil be modding the car to accept a glued in windshield. Believe it or not,this really helps too!
