Didn't get much of a reply on Kyosho nation.. Try it here..

"Right now I'm running the zach Rogers Setup, with 3mm on the rear hub, (alunimum) in the long link position and it's pretty dang dialed. But I have a TON of steering. I have it tuned down to 60% on my remote. Am I better off running it like that, or putting in like 1.6 pistons to take out some steering, and turn the steering up on my radio?"

Does anybody have a spare shock cartridge tool they would sell me. I have no idea where mine went and all the aftermarket tools are out of stock wherever I look.

well, I think the best response is going to be one I've said many times. If it works for you, run it. Set ups are EXTREMELY driver and track specific. I found the 2x1.6 hole pistons to actually increase steering for me. I run the 3x1.4's up front and 2x1.6's in the back. If you have made sure your droop and ride height are the same as the Rogers set up, maybe its something besides your shocks.

So on his setup, set rear shock length at 27 and front at 20.5 with no shock rebound and no limiters.

And I should be set to go?

I'm having a hard time finding a description of what blocks do what for the rear hangers. I want narrow and 3 degrees toe.

Okay folks I'm new to racing so bare with me. I finally figured out how to properly measure droop but now I don't know how to adjust it. I put the Zach Rogers setup on last night and it felt pretty good but I didn't mess with the droop at all.
