I club race on a true off-road track, bumps, holes, rooster tails. It's alot of fun. So I can probably help a bit with blown out conditions.

On the .3, I ran 500/550 with 3x2.1 pistons, and the black\orange LF springs. I wanted to try the grey\yellow LF springs, but snowfall hit before I could.

I have a feeling whatever our current spring\piston\oil combinations have been on the .3 buggies, will be similar on the .4. Then adjust from there.

The caveat to that being, the guys that haven't done any testing with the LF springs on the .3 buggies. If you haven't, and still running the OG buggy springs, start at 1 color softer than the buggy springs when going to the LF. And you'll also want to play with oils. I dropped my oil 200CST when I switched to the LF springs.

Basically, the guys that have already played and test-n-tuned the LF springs, and found what they liked, will be at an advantage when switching to the .4 VS. the guys that haven't.
