I would if it had one. Yeah no log just a dyno run. I'm not saying they are the best cooler by a long shot. Just people get all wrapped up in big rwkw numbers and big brand names. Cheap coolers on a well setup car can produce good numbers as well.
Gee those brakes will be insane. As for girdle, I would of thought with the power you have , you would already have one. Would definitely be a good idea.
I've widened 15" steel wheels no problems. Alloy is a a bit harder, you need 4 wheels to make 2, so there is only 1 weld .
How much power have you got? A lot of guys running 10's on 17". Just have to bolt them on.
I'm looking at widening some standard 17's to 10 or 10.5" and maybe putting a 315 under it. I think it will take some adjustments to the inner tray tub.
