I have wilwood calipers on the front of my car but unsure what model they are (powerlite or midilite)
How can I find out as I'm requiring pads ?

They are on Cortina uprights with solid disks.

Have a look on the rally design web site at the specs of them both and compare to yours.

I think the midilites have piston dust seals and the powerlite doesn't.
