Yes I know. Most karts that I see just have swing arm rear suspension. It looks like it's gonna be awesome!

Do the rear a arms move like the front or are they static and not move? I ask because I'm curious on how you'll manage to get the differential to flex in the rear. Usually it's swing arm, trailing arms, or a arms with CV axles or u joints that move with it. If that is your plan. You don't see many people use the Peerless differential, they usually just make the rear end a spool.

I plan to cut the shafts off the diff and build cv shafts.

Thought so wasn't sure. Any ideas which CV you'll be using?

NO idea yet. The arms are really short so it's making it really difficult to find any good options. Every other cv kart/buggy I've seen is a two-seater or at least as wide as a two-seater and mine is not because I wanted it to fit in the bed of my truck.

Wish I could help on that. Most cv axles that are used are VW type 1 and Porsche 930 axles. Which are longer.

Yeah I thought about trying to section and shorten a type 1 or something similar but even then if I section out ALL the shaft in the middle I think they would still be too long with the necessary flanges to connect them to the 1" shafts.

Does anybody have an idea on how to figure out the stroke of these shocks when I cannot compress them by hand?

So you're looking at RC type wishbone for it. No idea if anyone makes them. I'm sure a machine shop could custom make you a set. How long are you wanting to go (for the love of God, don't take it out of context). ATV CV might be short enough. From reading on other forums, you can't really cut and weld a CV shorter and expect longevity, just doesn't hold up well. U-joint style may work, but after 20hp or so, they don't fair well. That's where VW CVs come in at.

Yes exactly I just didn't know how many people would actually know what I was talking about if I said that. Here's my inspiration...motor is bored, stroked, ported, polished, and stuffed and the driveline has every upgrade you can imagine to be able to handle it.

My dad has a Grizzly lathe/mill combo so the reason I'm thinking dog bones is that I think I could make them with his help. I think the shafts will be roughly 10" long and I bet your right about ATV shafts but the problem is that none of these parts sites have dimensions on these things since they're just selling them as replacement parts.

Do you live close to an ATV dealer? Could run over and see if they'll work. If you can make dog bones, do it, wouldn't be any different than U-joint, just not as protected, unless you can put a boot over them. The last time I was up close to an ATV was last week at work and it was an 800cc Polaris, CV looked like they were about 14". Not sure they can be had smaller, unless a child size one has independent rear suspension.

This is getting interesting!! The 1/2" corded drill I picked up at Harbor Freight for $30 last weekend really saved me while drilling all those shock mounting holes today, but it actually snapped my 3/8" bit which was something I didn't really have to worry about happening before. I also ordered the material to start machining my drivehshafts today.

This is looking cool. Do you have a plan for the bump steer, or is there another set of arms coming for the front?

I was wondering the same. But the OP would have to modify the front a lot to make that happen. He will just have to deal with it i guess. not much you can do except redesign the front end to fix that issue.

Looks good so far.

Exactly my response. Lol My plan is just to deal with it. If it's a huge problem and affects the driving experience I will probably try to pickup a non running mini quad off Craigslist and graft the front end on to the kart.

You going to put a brace on the top of the spindles for added strength? Edge buggies have single A arm suspension and don't suffer from bump steer from what I've read on minibuggy.net. So long as it's designed right, there should be next to none.

Hey thanks for mentioning those they look pretty neat. A LOT more expensive than what I've got going though lol. On the Edge Piranha it looks like the steering rack ends are on the same axis as the control arm pivot which would result in zero bump steer. That would have been a good idea to try to incorporate into my design but it's a little late now. I do have some noticeably bump steer (already measured it when I put the spindles on) but I don't think it'll be too bad.

Consider it as an option for a possible revision if it gets too bad to deal with or future buggy.
