But will MMC choose the ARP4 version or the Suplex one?

Cheers

Their own...I don't know why they would fit the Suplex aftermarket system?
Dave....as you know, I've always been a traditionalist as far as chassis and suspension are concerned, but now having driven the ARP4 twice, I'd happily embrace the new suspension.......if it was a reasonable price option. Notwithstanding handling improvement, the comfort improvement alone in my view is worth it. It does however highlight any problems with the front end so that would need to be set up properly.
