How much thicker are they compared with the M Sport arbs?
I really can't imagine they'd make a difference on an sdrive M Sport considering how much thicker the standard arb's are than the "thinner than SE" arb's that the xdrives come with!
Nonsense, they're still way bigger!
The MSport ones are only a mm or so larger. Plus it's the larger relative increase in the rear one that really goes to dial out the understeer characteristics.
