Has anybody tried the YZ2 rear end on this car as yet? Raced mine Friday again and bagged a second overall, but found it over rotating a tad, and early on in the heat the rear was very loose.
Was running 650cst/Yatabe Purple front, 4mm droop limiters, 450cst Yatabe Orange rear on the shocks, but we run on Venoms, with 4WD cut stagger front tyres, so just wondered if the YZ rear arms and shafts i have lying about would bring up that rear bite somewhat? On the whole though, what fantastic car, my first two meetings with this car, and in 4WD have gone down very well. Lee

What roll bars are you on?
YZ2 arms and shafts made it worse for me, but i'm not running on super high grip carpet or astro. if your track is med-loew traction, stick with kit or B4-008R1 arms.

Med-Low, the YZ2 arms should be better. That's why on high grip we go to the BMAX arms on the YZ2.

Got a lot of front grip, just over rotates a fair bit on cold tyres! Carpet is medium in grip if say, overall though love the car, 4WD seems to suit my driving way more TBH! Lee

But it's not better? Car was a lot looser for me on rear in the low traction with them on. Returned to the +1 arms and it's good again.

You could also run -2 camber the front. Your fronts are gonna make the car over rotate in comparison to the rear tyres you are using. Try dropping your rear roll bar to 1.5 also.

Kit front hangars are gonna give you extra steering also which may be what is pulling the car round. I tend to always run my front hangars in the low roll centre with the widest track. So, the inserts would be with the arrows at the bottom and facing outwards instead of inwards.

On the bmax, we have run the yz2 arms everywhere, low and high grip. On the yz2, we have been running the bmax arms on high grip. I think I'm the only one to have raced low grip, but I have been switching back to kit arms for low grip.

With the +1 arms do you need to make any changes?

On my bmax4iii, i found the narrower yz2 rear arms to be worse on sandy medium traction astro, and Yorcc gym floor low traction, so i went back to B4-008R1 arms. I've not run yz2 rear arms at RHR though. Allan, what's the technical reasoning behind the arm width for high or low traction?

Allan, Neil, car was way way better last night. Changed the front hangers to arrows out, and i did leave the 2mm rear roll bar in, but swapped to Yatabe rear Purple springs, way better balance, managed to put it 2nd on the grid and came third due to driving like a right numpty, Finals arent my strong point lol, but for sure, car was great.
I will say on these 4wd staggers, the amount of front grip is bonkers, im running 4mm limiters in the front, may step that up to 5mm next week! lee

Cut the outer row off the staggers, that will help a lot.

I am finding the same. Just bought a 4 III and first run on the weekend and it had a tone of steering and was also very loose and sliding in the rear. Kit setup basically with 2wd stagger ribs front and mini pins rear in yellow compound. Med/High grip indoor Carpet.
When you guys talk about 5mm of limiters in the front shocks are you saying 5 of the little Yokomo shock limiters ? Or an actual measured 5mm worth of shims ? As 5 of the Yokomo limiters would only be 4mm measured as they are only 0.8mm thick each. Kit has 2 in the front. I just put 5mm worth in and now I pretty much have no droop at all. Is that right ? Seems like a very extreme droop reduction. Excessively so. |

Didn't want to start a new thread but I think I read that some people were reverting back to plastic shock caps, if so apart from weight what's the reason?
