Im the 3rd owner of my current mustang. I bought it off my brother who bought it when he was 18.. He did it all clutch drops, long burnouts... lets just say I replaced a lot of parts when I got it. They can take a lot of "abuse"
A buddy of mine out of highschool had a nice built engine in his and he had bolt in subframe connectors. He ended up twistin the frame and ovaling out the bolt holes. there was a wrinkle down one of the rear quarters. he ended up fixing it and selling it. I the guy who bought it is on there, sorry about that. man that car was fast.
