French Coust's are bonded into Magura backings which are much stronger and stiffer than the power pad backings Steve uses.
Also Steve bonds his pads a different way to Michel.
If you're changing the whole lever including the body it should be fine. However if you where thinking of just changing the blade it wont fit due to the cam design inside the Deore.
One of my mates uses Snafu Rim Jobs front and back. Aside from the Sh*t name they seem really good, he uses them on his 4X bike he uses for racing and on his street bike.
I'm about to purchase a 2013 ford fiesta this week but the wheels are so small.
Can someone tell me what wheels will fit.
Edit: I was looking at these ST 17's http://www.ebay.co.uk/itm/231053664278?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2648
