Did you figure out the tire size limitation on the front from the K-frame? It was quite easy to put the 275-35-18s in the car in my case with the stock stuff, so was suprised to see such narrow tires.
For anyone that might care, while Joe didn't have an issue with this, it is a valid question for some of the other kits out there. My brother is doing a Demon with a ControlFreaks kit and it cost him like $1000 each for custom wheels so he could fit a skinny 235 tire under the fender. Not saying he couldn't have found an off the shelf wheel that worked, but it wasn't a common size and the track width of the kit he bought was an issue.
Not pertinent to the HDK kit, but maybe someone will find the info useful.
