If it is true the power to weight will be truly stellar, better than E60 M5 and the same as Corvette C5 (8.0). Again this assumes 426 hp.
Also note that the 335 shares the same chasis with the 328, but it weighs 220lbs more than the 328.
I can't remember the source where the assertion is made with regards to keeping the weight not more than the E46 M3, but I will send the link if I do find it.
With RCF use, I can see them pulling it off.
