Good for the race car.
The good: protect all parts from extreme heat, never burn your hand when touch it.
The bad: hard to keep it on need glue and lot of safety wire to hold them.
The ugly: It's stink, it will stink for a week when you first put on then everytime when it wet like you drive in rain it will stink until it dry.
keep money for something else better but it's your car.
