There is, I just got the shims today, instructions advise to use the same amount of Z4-300RFS to match what you use with the Z4-300RRS shims. What it basically doing is raising the suspension mounts both front FR/RR in the rear of the car by 2MM if you go by Carsons setup sheet. Easily can be done using ballstud washers instead and save some cash.

Your original post questions z4-300srf not z4-300rfs. Bloody no.s are confusing.

Z4-300RFS is the correct part number.

I am trying to set it up for dirt. Anyway, thanks for the help, I will have a look at the setups links you shared.

Has anyone figured out what fronts from other manufacturers work better on this buggy? Kyosho offset? TLR/D413 fronts? Need to run AKA Pinstripes up front.

I bought my YZ4 used, with all of the goodies already on the car. I was horrified by how tight the belts were. I wen't through the manual, read this entire thread and decided it was a design flaw. It is. Really guys. I removed one of the tensioners, and moved another, got the belts looser, and the car was great. They really don't need that much tension. My Schumachers don't run anywhere near the tension of this car, and the belts don't slip. BTW, while I thoroughly enjoyed the Yoke, my Cat K2 was faster. Silly Shuey haters. Anyways, I removed the lower rear and moved the upper rear to above the upper carbon deck. The car behaved as it should. I didn't have to remove any drag brake at all. Very nice. I did notice that the chassis slaps pretty good quite often. Easy fix. Anyone ever use the MIP Bypass pistons? I love them in my Kyoshos.

I am running the VRP bypass pistons and love them. I am running the latest marc rheinard eos pully setup . With just the pulleyon each side of the spur layshaft it does not skip

Hey, everybody.

I am looking to replace the plastic bellcrank that comes with the kit. I've seen aluminum ones for the yz2 but havent seen any for the yz4. Are they compatible?

Ive been driving/racing the car a lot over the past 2 months and my front end is starting to get a little sloppy, im worried that im losing a bit of steering so im planning on replacing most of the steering assembly to tighten things back up.

Edit: i saw on amain that the aluminum yz2 bellcrank is listed as yz2/yz4

on my rear belt I used a 3x7 bearing in the front instead of a 5x8 ... made the belt much looser and used a 3x6 bearing in the back. I,m also using vrp 1.5pistons and 30wt oil with losi front truck springs in blue in the rear

@carpetburner...so there are no bearing tensioners, just the center pullies in the marc rheinard setup?
