YZ-2 with Bmax4 III rear wishbones.

[dpackster1980]

Anyone thinking about trying the above don't, just get it done.

I ran mine for the first time with them on tonight and what a difference. It's a completely different car, yes the steering is still aggressive (this will be resolved with gull wing wishbones) but if the back end brakes away it's recoverable and no where near as servere as before. It seems to ride the bumps better too and easier to jump if you balls up lining it up. I was coming out of corners and able to get on the power earlier. The grip and side bite generated is emense. It's what the car should have been from the start IMO.

I was on the verge of giving up on the car thinking it wasn't for mere mortals but not now I'm loving it.

I've just done mine, but not run it yet. Looking forward to that.

Still think you had something wrong with your build Dave. You are the only person I've spoken to to who's had an issue with the car. Mortals, myself included have all improved with the car, out the box, but you struggled?

Glad to hear you sorted it now.

Does anyone know the exact figure of how much the car is made wider by? and where it is done?

I'm looking to upgrade to this, however im wondering why cant the car be made wider by spacing out the wheel on the adapter like how durango did?

[neallewis]

it's about 2-3mm/side at a guess comparing wishbones.

Widening at the hex/axel alters geometry and roll centre. it is better to move the outer wishbone pin out and keep it close to the wheel.
Durango did it the cheap way.

Moving out at the wheel helps with grip and to a minor extent stability, but moving at the inner pin gives extra roll stiffness as its altering the leverage of the wishbone.

You're looking at approximately 7-8mm.

Been running this set up for weeks now, wouldnt go back. I tried it to help with high grip roll, and it worked like a charm, made the car way more stable too.
Have to say though, Neal seems spot on, all ive done is improve with this car, it can bite you, but rarely does and its even better with the wider rear stance.

Thought the bmax4 arms were only 1mm wider ? Soo 2mm total ?

Compared mine and a fellow racers and its at least 3mm wider per side. Obviously cambers were different. I also compared the length when they were off the car prior to fitting. Did you? No.

I suspect that you're thinking of the Bmax4 + 1mm wishbones which would make the 4wd 2mm wider but would be daft on the YZ2.

So I can't just use the wishbones and dogbones from my BMaxiii on my YZ2 and vice versa?

Yes you can.

I tried my bmax4-3 with the YZ2 rear bits, and put it back to the B4-008R1's.
Felt too loose at rear on the new sandy Batley astro.

[discothesnake]

Just run the bloody things the way they were meant to be! They'll be fine....

[Ashlandchris]

Brilliant

But we all like to tinker

That said, my yz2 has been superb, everywhere I've run it. Straight from box (with a little expert adjustment from Neil Lewis)
