Correct this slows the rebound, which is what you want.
It allows you to run softer oils without getting the bounce back from landings. It's commonly believed that the bounce on landing comes from the chassis slapping, but it's not the case. It comes from the fact that chassis slapping happens when the oil is a bit soft, and that is the same on compression and rebound. So with normal pistons, when the oil is too thin, not only the chassis slaps in the ground, but the rebound is also too fast, and that is what makes te car bounce back on landings.
So with te tapered pistons, you can run softer oils without having this issue. Yes the chassis will slap on landings but it is not an issue.

Taper side always up.

the taperd side should be facing upside.
every car in the 1/1 scale world have slower rebound than compress. i have been talking alot with ohlins and they have give me alot of good tips for me what regards shocks!

Hello, could someone tell me which part is in the setup sheet in Rear Shock, the "Pivot Ball Position: Front-Rear"
Thanks. Best Regards.
Thanks. Best Regards.

He is asking what way the steel ball for the rear lower shockmount is facing. You have microadjustment of the shockangle in witch way the steel ball for the shock are mounted on the rear suspensionarm i guess... I have not recived my car yet and it could be some time before i get it BUHUUUUU!!!

Yes this is correct "Pivot Ball Position" is the direction of the steel ball on the shock end, you are able to change the shock angle by which way you mount the shock in the arm. I havnt played with this setting too much, I guess it changes the dampening some. I guess when you mount the shock to the arm and the flange on the ball is positioned toward the head of the screw it will make the suspension slightly softer than if it was mounted the other way (thats for the rear shocks, not sure if in or out makes the front softer or stiffer till I try it).
The manual on step#22 has a pic of the pivot ball position on the bottom right window.
Ya im confused now on tapper position, A few years back while on Jammin we tested tappered hole pistons and me and Halsey would argue on the direction (tapper up or down). I thought that the tapper down would have faster rebound because it would dirrect the oil more to the hole, however he said up because the oil has to flow through more surface area (on compression) of the piston. we tested up and down and I honestly couldnt tell a diffence till we tested the actual shape of the piston (thats when I noticed the change in compression to rebound speeds).
I know for a fact that piston thickness has a big effect on dampening as well. I had a 1.3 6 hole piston (on the jammin buggy) with say 30wt shock oil, I changed that piston out to a 1.3 6 hole piston (but this piston was only 3/4-half the thickness). I had to go up nearly 10wt thicker on shock oil for the thinner piston to feel like it had the same dampening as the standard thickness one. But I think this is kinda usless because it doesnt change rebound or compression, it just changes the dampening.
