Setting rebound on Jammin X1-CR
Hi,
I'm trying to setup the rebound on my Jammin X1-CR per the setup sheet which indicated 20mm rear and 26mm front, however, I couldn't get anywhere near that using a mounted tire underneath the car to prop it up.
I was hoping that you guys could take a look at the attached pictures and let me know if everything looks like it has been setup correctly.
The extension pictures of right before the tires come off the ground.
Tnx

I may be wrong, but those look like Mugen MBX5t springs
My guess is that you have the wrong springs on the car.

THOSE are the stock red jammin. what are you trying to set here....take the tires off and sit the car on a wheel front and rear then measure the inner and the lowest part of the lower arms,, and in front measure in the bottom of the c hub, it should be buggy wheels.. Idk if its right but thats what team drivers here taught me.. good luck.

It looks like he's setting ride height.

I couldn't get anywhere near the 26mm front and 20mm rear that the Jammin setup guide recommended. At the utmost extension I have something around 30mm.
Exactly, trying to set the droop. Jammin refers to this as the "rebound".
Wouldn't mind some feedback on the ride height as well.
Thanks everyone.

General setting for droop is to set it so the arm stops before the shock runs out of travel. more advanced settings can be done for specific track conditions.
With mine i look to do 2 things with my droop settings on my x1.
1. have it set as described above, arm runs out of down travel before the shock does.
2. have them even side to side.
I am running on some fairly bumpy tracks so i use all the travel i can get.

It looks like you have the droop screws in way to far and not enough preload on the shocks. Are you trying to set the ride height with the droop screws?

No, not setting the ride height using the droop. I set the ride height using the shock preload (i.e. twisting the little nut thing on the shock body to move the spring.)

Oh ok, I just noticed that you had 0 preload that is why I thought something was wrong. i think when I had my Jammin I measured from the hub and not the arm. the hub hangs a little lower then the arm I think, could be wrong though. A couple recomendations for you other wise, get yourself some mugen grey springs, if I remember correctly most of the old pro setups list them rather then the Jammin reds. Also, the rear camber links, most guys were drilling a 7th hole to mount it in. You can see it here, http://jamminproducts.com/CRsetups/x1supCBv2.pdf

I always started with ride height set to arms level all around on my X1CR, then changed it as needed according to the track. When you set the droop you need to remove your set of wheels/tires, set two unmounted wheels under the car, then measure the lowest part of the arm in relation to the table. Using a mounted wheel/tire under the car is going to raise the car up too much and you won't be able to get the droop set correctly.

Does the ride height at least look right? 28mm or so. That makes the arms pretty much level.
Yup, I was. Assuming you are the person who was helping me with the RB, I took your advise and got rid of the JP1 and got a RB 2045 pipe. It just arrived today, dying to give it a try. It looks like a beast in comparison to the JP1.
