The rear will eventually be getting about a 3" kicker right at the end of the trunk lid. I have enough gap between the trunk lid and the quarters to get some uprights snaked though there.

This car will likely top out in the 150 class with a max allowable speed of 165. I have enough engine to pull higher speeds, but the cage requirements start getting really invasive for a full interior weekend cruiser. Not to mention the requisite brake system upgrades beyond what I'm already running. Anything faster will be in a dedicated car.
