SH Z-Car ZMXB-8 1/8 Buggy - Perfect for conversion?

Those Kyosho shocks should work a lot better than the Z-Car shocks, no doubt.

I haven't completely understood the purpose of the valve either. But from what I have concluded they should increase dampening slightly on the upstroke (compression) because they make the flow of oil more turbulent. Or something like that.

With valves you can tune suspension to progressive (allowing it to be stiff over small bumps, but get relatively softer over larger bumps) or regressive, similar to conical holes in pistons. But conical holes work only in narrow zone. But valves work on full lenght of shock travel. I like idea of valves in Z-car. But dont know realy how well shocks works

tom255, I understand how the valves work, I have them in my Revo PE, the thing is the Z-Car valves have holes in them that line up with the holes in the piston, so they really don't act as a valve, as the oil just flows right thru the holes. I may experiment with the Z-Car valves and either make some new ones with no holes, or redrill the mounting hole so the valve is moved over slightly so it blocks the piston hole (at least partically).

I had a chance to take it out on the track this weekend and I must say it performed very well. I have been wheeling Kyosho buggies (Kanai III and 777 SP2) for a while and the Z-Car seems to handle better, I don't have it setup 100% yet and I had some issues dialing in the rear suspension (I changed out the shocks with Kyosho Big Bores) but it corners and jumps really well. I took a couple of big hits and it came out with any breakage. The lighter weight overall and especially the drivetrain (thin driveshafts, smaller diffs, milled outdrives, etc.) seemed to allow it to spool up faster.

Also, Amain Hobbies use to carry the Z-Car but stopped because of lack of sales and that they were not impressed with the buggy. I started a post on the Amain forum and MadRussian and I have been trying to get them to carry them again, especially the parts so we can get some better pricing. Please go over there and post your opinions.
