Went back to the track again this weekend for our last MSRA race. I was hoping some of the suspension tweaks made this week would help tame the launch and avoid the high wheel stands. The cars not leaving perfect, but I'd say it's much, much better. The car will now run with the wheelie bars on and not unload the rear tires. The air quality was worse today as compared to last weekend, so the performance fell off a small amount.

All runs today were made on the new Hoosier 325/50-15 DOT Drag Radial tires.

60's were 1.296, 1.294, 1.299, 1.292, and1.308. The first four runs were shallow staged and the last I bumped in pretty deep in an attempt to help R/T on the .400 pro tree.

Here's some videos I had a racing buddy film so I can break down the launch frame-by-frame and study to see if any tuning changes are in order. Be warned they are a larger file size, approx 1.5 megs each. They were saved as a larger image size and higher quality.

BTW, changes made were tightening the front shock rebound by 4 more clicks. With even better air coming (hopefully) I expect to have to either tighten the shocks even more, or take some more travel out.
