Anyone know what setting the stock plastic rear toe/squat block is on the matrix buggy? I'm running the red 3T3S block and the rear end is a little loose in the corners for my taste. I was thinking about trying some different ones, but dont really want to drop $40 a pop to try them. I was thinking if I knew what the stock setting was and compared it to the 3T3S i have I could estimate about what I want based on the charateristics I get from those.
