Peter - the sportmax rt2 has been released recently. You might want to check if you can get these in the right size. The Dunlop UK web site does show them for my Aero Coupe which are the same I believe.
I would also consider the new Michelin PS4. Whilst this is called Pilot Sport like the PS 3 etc it is actually a development of the Pilot Super Sport and so a great tyre for the Aero chassis. I have put the MPSS on the Series 2 and it has made the grip/handling wonderful but not wrecked the ride.
I used the sportmax race on the back of the MB E63S which were more like track day tyre and when warm they were amazing but outside that a bit difficult so avoid them.
