i am very curious.
you three musketeers are so involved in overall speed, why drive a heavy BMW saloon?
there are other posts also about comfort with sports suspension as well.
i mean, yeah, the quest for more if always there but the items being brought up for discussion make minimal to no improvement to performance, but more rather for aesthetics.
if you want speed, go boosted in a JDM. Even a stock standard JDM will walk all over a stock UDM. Serious!
