IMHO Stg 2+ is the sensible limit for a FWD Cupra chassis and as already stated there will be sod all difference between 95% of the 2+ ones if variables such as driver, RR and atmospherics were removed.
I too am very interested to see these AWD beasts developing and would love to undertake such a build in the future.
