We had some D03 M1's we tried at Symmons, we found they build up pressure way to fast. I'd do a 5 lap's, come in and drop them to 32 psi, do 5 more laps and have to drop another 5-10psi out to bring it back down to 32 psi. and you could do that all day long, i'm surprised there was any air left in them.
I run D02 R1's on my R32, and they are much more stable. The RE55's SR on the Targa car are very stable too.
