Had a real good test n tune day with the BR6 yesterday. I'm really pleased with the performance so far. I ran Ben's most recent setup except for the piston/oil combo. I used the new 15.2 pistons with 600f/400r. The track was pretty clapped out from all the rain we've had, but even in those conditions the car was fast, super stable, and predictable. I dropped the gearing to a 15t clutch bell. I'm also really happy with the feel and performance of the Thunder Innovations Pro One aluminum clutch. I've preferred the feel of a four shoe clutch for a long time, and this clutch with 2ea. 0.9 and 2ea. 1.0 springs felt exceptionally good.
