on the Z-28 cars with automatics, and all I can say is holy hell, I lit them up in my driveway to test it out I made so much smoke my neighbors came out wondering what the hell was wrong, the cops came about 15 mins later after I was in the house. they hung around for about 30 mins on my block lol..

but the launch is something to behold, now I've got my set of 3.73's on the way..
