Powerlites
Would willwood powerlites with the 1" Pistons be adequate on the front of a mk Indy, mostly road use.

I think so as well. But rally design reckon I'd need the bigger piston size, which seems over kill.

I think you should ask them if they won't be man enough for a light weight MK Indy, why exactly are they man enough for?

They said rear brakes on a track car.

They recommend on their site a maximum vehicle weight of 750kg, assuming that is based on the largest piston area, and use on the front of the car,
and that the figure of 750kg is accurate, then it would seem they have a point. However, I can't find anyone else quoting that figure.
Just to add, is there any reason against the larger piston diameter? I assume the weight difference is negligible and I can't see on their site
that their is any price differences?

That's the set you should be ordering. No mention of bore size !

I'm with RMD's viewpoint, 1" should be on the rear of a track car, 1.3-4 should be on the front. That's my real life
experience, worth nothing, but a viewpoint nonetheless. The Powerlite has been a superb lightweight caliper, keen pricing too, used them on both the
W/field and R1oT.
Obviously changing the m/cylinder bore size(s) will get anything working (within reason).
RMD's dual thingy is (from memory) 1", I've run the Triumph dual thingy which came out a .75" each. With a proper individual
dual cylinder set-up, usually .7-.75". depending on what 'feel' you're after.
These were all fitted to various underpowered lightweight BEC's, with some good laptimes.
