Now we have finally got the four link to about something that works, but what baout the rear shocks. Should they be stiffer or looser? It seems that hte car looses traction for a moment after the launch now, but picks it back.

We still have our national finals left, but basically we have already clinched the championship, just have to get one qualification run in the finals!

It looks to me like its hitting the tire very hard initially. The extension needs to be tight enough that when you push the back of the car down it takes 2-3 seconds to rise to ride height. I would do alot of tightening on extension and maybe 1 lb more air in the tire to start. Hard to get really into detail with a shot that far away.


One day I will have something cool here.

Kinda hard to say much from those views but looks like it hits hard then looses traction. Might try stiffeneing the extension so it does not hit as hard and softening the compression so the tire can stya planted once it hooks. Do you have any of the the 4 link info handy? Big car with a long wheelbase and lots of power..

Sorry man, I can't see enough to make a call.

What's it feel like it's doing?
