Hi...is this the same gentleman by any chance?
He does rears too. Very attractive prices if the fit is good. 

I am relying on my memory of 2 years ago, but I THINK that Ebay ad is the supplier I used.

As regards "if the fit is good", there is a fundamental problem with ANY adaptor bracket which locates on the two surfaces MG spot-faced to accept the heads of the M12 bolts, rather than the fully machined side of the same holes which the calliper carrier attaches to when in the standard, 240mm disc position.  I tried to explain this problem to the supplier when he blamed "inconsistent machining" for the difficulty I experienced.  my email text was:Thanks for the quick reply.  You mention "Inconsistency" in MG's machining, which is undeniably true BUT, to be fair to them, the Al Alloy adaptor is attached to (and effectively positioned by) the two surfaces MG spot-faced to accept the heads of the M12 bolts, NOT the reference face of the standard callipers.  I suspect the machining tolerance for THAT (reference) face is much tighter.  Inaccuracy/inconsistency of the spot-facing only effects the depth of penetration of the attachment bolts, which would only become a problem if it was wrong by a couple of mm.

The end result of this is that you MUST be prepared to carefully check that the alloy adaptor with the calliper carrier attached ends up with equal width spaces either side of the disc.  As the 280mm disc does NOT have any retaining bolts (as per the std 240mm discs) you need 4 bolts with the correct thread to suit the wheel studs.  It is a metric fine size IIRC.  These will allow you to bolt the disc on without the wheel, so that you can check you have the right washers between adaptor & Hub.  Hope that makes sense!!

You need to read the Word doc I sent to help limit confusion.
