the 10.5 is the tire size. its about as close as you can get to a run what you brung class. you have to run small tires but hp is pretty much open. they all have way more hp then they can use with those small tires. any most run low8s to in the 7s.


the turbos just sound so bad ass on the big end at almost 200. they will be in orlando in a few months for worlds fastest street car. its really the only show worth going to these days
