Hmmm, not by much, it shouldn't affect the 'tune' as both have the same weight distribution and the same 'travel' available in the springs. Both are 4wd front engineed but one is 20kgs more than the other..??
Maybe that's the weight of 'guilt' it carries for being a shamefully blatant 'copy' of the other one!!!
I'm not sure (I don't race these cars) but a guy was talking in my lobby a few days back about the Astra's (same thing - Opel & Vauxhall versions 'seem' to be copies of each other), but is is actaully quicker..??
I haven't a clue, I guess guys who race DTM cars alot can shed some light on this??
Would be interesting to know if this is just hearsay or fact...
