My transmission slated for my West Coast is the Richmond Over Drive (ROD) 6 speed, low first, and way overdrive 6th.
17 inch wheels, low profile z rated Michelins
The WCC's are easily 500+ lbs heavier than your car, and I think this will be fine, since I have a 600+ horsepower motor planned...I suggest strongly the 3.27 gears, or you will be doing the kind of excessive rpms the guys just mentioned. Your cobra is light, and has plenty of pickup with the higher ratio....I want to use 5th gear if needed, on the highway, rather than go to taller gears and use 6th...there is a great advantage to the 6 speed, if you don't mind shifting more often (part of the fun for me)
More gears are better!
Bigger is better!!
