I used M2s at Round 4 of the JBRL at Heritage and at Revelation a week ago because it was quite toasty. They work great in the hotter temperatures. My qual at Heritage was very wet and it was still fairly cool (80°) and they were terrible but came in perfect by the main. Ran an entire day of practice on them at Revelation after JBRL. They probably had about 30% tread left at that point which I made short work of on the asphalt breaking in the engine. I ran the Impacts at Round 5 of the JBRL at Proline (is that wrong ).

Oh, wanted to mention that the fuel tubing on the brake linkage worked quite well. I also dropped expo to 60 and now it feels pretty good. I have to reduce the EPA bit more but it's a huge improvement over what I had. Thanks for the tip.
