Re: Plus 2 front brakes on a 2 seater

I'm intrigued by what benefits people are expecting here.
As a +2 owner, I'm not clear from the thread whether the disks are changed as well.
I would expect that the increased pad area could provide better fade performance, especially if combined with larger disks. Do road going Elan's need better fade performance? Pad wear may be less to but so what. Not sure what else people are expecting.
Obvious downsides are greater pedal pressures required (or more servo or greater pedal travel) and this also increases the loads on the pedal box components. Greater weight and, more importantly, unsprung weight with obvious ride and handling penalties.
If the +2 calipers were a better oevrall solution I suspect that Chapman would have used them. They were after all readliy available and the cost difference would have been small, even for such a notorious pennypincher.
