im tryin to find out information about the plymouth VIP and how it compares to the imperial as far as frame thickness and strength. the reason i ask is i was at a derby and the imperial is outlawed. someone supposidly put a VIP sub frame (if it was even a sub frame car) or if it wasnt a sub frame car they used the whole frame. i know the imperial is a strong car and im tryin to find out how the VIP compares to it because this is the first ive heard of a VIP as well as alot of the people at the derby. the only info iv heard is it was an imperial frame with a different body. i dont know if this is true or not. any info would be greatly appreciated. thanks. josh
