Were you planing on supercharging or turbo charging? I had no issues with clearance under the hood with the supercharger kit until I decided to alter things & add components of my own. This hood will be swapped back to my turbo car & the hole will be patched. I plan on making a cowl type hood similar to the newer GT500
As far as the brakes go the stock 4 pistons up front are nice, I'm just fiddling around. I plan on using the factory front 4 pistons on the rear with larger rotors like Higgi from another forum & one of the two caliper set ups from above. I may just do the Evo brake swap, not exactly sure at this point.
I have a few plans other then the exterior & brakes I also need to attend to (interior)
