I got to try the 7.5's with Adam Bailey's outdoor setup this past weekend at the outdoor track. It was a bit muddy, but manageable. I put the alloy upper tranny blocks as well. They are a few grams heavier, but it acted just great. It was my first time this season outdoors, and the JConcept DD's were hooking up just awesome. Next time I will try Simon's outdoor euro's setup, see how it hooks...
Thanks boys
