You must be refering to the lower arm mount that adjust "kick up", which is located at the rear of the front lower arms, because that's the only one with the two location pins that go into the chassis. I run the -1 on the MBX5R, and the Mugen mounts go 0, -1, -2 starting from bottom(closest to chassis) then up. 0 will give you the most kick up(arms leaned back) and -2 will give you the least kick up(arms more flat) Less kick up will give you better steering response and handles better on a smooth track, and More kick up decreases your response but it will handle better on a rough track, that's why I just split the difference and go with the -1 mount and leave it.

Barnes,

Do you run the little seals in the diffs? I left mine out it made the diffs "feel" tight.

And on the upper front arms, do you have your push all the way forward? Im looking for aggressive steering.

Daniel, That 5r has all kinds of steering.. Most people run the arms forward on top and back on the lower arms for the front. Look back a few post, and you will find some good setups, or call me here at work 982-5127. Twig

I don't run the 4 small o-rings that set behind the small spider gears in the diffs, they serve no purpose and only cause drag and heat from friction. As for my front upper arms I currently have only one thin 1mm spacer in front of the top arms, and the 2mm spacer is in front of my lower arms.

That's funny because i am finding it has too much steering. I have lots of over steer and its very twitchy on the steering too.

So i have been doing the complete opposite to most to try and get it to stabilise and calm down a bit.

I am really amazed at how different my R is to all the other R's with steering, even when setup exactly the same.

Make sure you enter the corner correctly because no buggy will ever have enough steering if you don't line it up for the corner correctly. ... This is asumming your setup is all good.

Sebs -He was talking about the old MBX5 that he ran last year, not his new R.

Hey Ryan,

Do you know what effect on handling lowering the alloy rear uprights has ?

Thanks.

Timox- If you think about it, by going from the upper to the lower hinge pin holes you are lowering the buggy's center of gravity. Because your wheels/tires and rear hubs are staying in the same place in reference to the ground, but the whole rest of the buggy(weight) is being lowered closer to the ground.

I assume you're talking about moving the pin on the rear lower arms to a higher or lower hole on the upright, right?

It wouldn't really change the CG, it would change the roll center. The chassis (and therefore the mass) would remain at the same height, the angle of the lower arms would change. I guess that one you could say that some portion of the rear arm would be lower...but really...it would make a pretty big difference on the roll center.

My answer would be:

a) if rear arm is attached to buttom most hole on the upright: a lot more rear traction (entering and exiting) The rear end does not want to brake loose, but if it does, it will slide for a bit before it stops. This is my observation.

b) if rear arm is attached to top hole on the upright: the rear end is more floaty, it rotates with less effort... my observation and advise if you run this setting is to realy watch that throtle finger.

What has everyone else discovered about this kool feature... and sometimes overlooked?
