Hi all. This is my first attempt at building a buggy. I am 17 and my younger brother and I have built mini bikes, go-karts and one off road go kart. We have some welding skills and have done a lot of research. We were given a donor quad for the project that has a 300cc engine which we will be using. It has reverse. So far, we plan on using double a-arm suspension, and swing arm rear suspension. We are using as many parts as we can from the 4 wheeler such as the hubs, wheels, engine, and hopefully brakes. I included a picture of what we have so far. Please feel free to leave both negative, positive and constructive feedback as this is a learning process.

It says "upload of file failed." It is saved on my computer and it is small enough. And suggestions?

I personally like using an atv for a suspension and parts. If a part breaks or wears out, a replacement is easy to find instead of having to build a new one. Just try to mount the motor as low as design will allow. A motor mounted to high will make it want to roll over in a high speed turn.

Just go with a Photobucket account and it's EZ-Pee-Z.

Cole,

Do a search on here Jeep Buggy Thing I think this is right. The guy did just what you are looking at doing. I wish he would come back sometimes. Super nice buggy is not the word for this build.

Not sure if Biker meant this one, but it's a neat little buggy for sure!

This is where we are at so far. We have mounted the front a-arms and the wheels were just placed there to get a feel for what they will look like. The whole thing is surprisingly square.

If you guys dont mind, i'm going to have a lot of questions through out this build.

Thanks for looking!

Wow that is really similar to what we are building. We were planing on using rear swing arm suspension because using IRS seems not only really hard, but much more expensive. It seems to me that using one solid axle with pillow block bearings would be much cheaper. Am I missing something? We can defiantly make rear a-arms but I'm scared of buying the hubs and bearing hangers and CV joints and all the other stuff that goes into IRS. Any input is greatly appreciated!

Yes That's the buggy!!!. Cole, Just do what you can. Ask all the question you like. The other guys can help you better than I can. I haven't posted much here but some of these guys are down right good. Keep the pictures coming.

It's not upside-down! Am I missing something? all we have so far is a basic base to the frame and the front A-arms.

Also, as far as the way this site works, is it better for me to ask questions by creating new topic in the lounge? Or should I ask here?

Ask here for the most part. If the question is about world peace ask in the lounge, if it's about your buggy, or anything that might be in or on your buggy ask here.
Looking good so far.

Sorry. I meant the photo. See this is how the photo looks when I view the page.

Alright everyone! The project is moving a bit slowly due to lack of funds but here is a quick update. We got the rack and tie rods mounted and it appears that we have 0 bump steer! We also made a good start on the role cage. Going back to my question about the engine, it sounds like we might be using a v6 off of a crashed 98 Ford Ranger with 70,000 miles on it. Will it be hard to get it to run out of the original vehicle? I included some pictures below.

UPDATE: So we decided not to use the ford engine. Our parents dont know anything about this hobby and I think they got really scared when they heard about it. For now we are using a modded 420cc lifan engine. We will be running a CVT to a hi-mid-low-reverse gear box. We have made lots of progress including seats, roll cage and steering. I will post pictures within a couple days once im home. Right now i'm stuck in vegas due to cancelled flights :mad:

Thanks for looking!

cole I have'nt seen your thread before. I built a sabertooth 2 lt. and the front a arms inner pivot points are exact opposite of what you have . mine by design, have the upper pp wider than the lower pp. yours are wider on the bott.than the top. my buggy drives straight and handles well and Im concerned that the way yours is it will not . check out others builds and note most all will be opposite of what you have.after all the hard work you dont want it to handle like a turd.

The reason that they are offset the way they are is because the atv hubs we are using have the same offset. because of this both the upper and lower a-arms are the same length. I will take pictures this weekend and post them. Thanks for your concern!

It will handle better if you shorten the top a-arm and move the top a-arm inner mount out. As it is now, when the car is in a turn and the body rolls down on the side that is to the outside of the turn, the out side tire will lean out at the top. You want it to lean out at the bottom, in at the top. To visualize this take the shock off of one side and let that side down. Do some research here on suspensions.

We have made some progress! The seats have been added as well as the floor. The seats were bought with sliders off of a go-kart website for $32 per piece! Here are some updated photos. (next post)

looks like you put your inner pivot plates on upside down. top a arm needs to be shorter than bott. you will not like how it drives the way you are building it.

Here's the thing; The offset of the inner pivots is the exact same offset as the wheel hubs have (odd hubs from an old 4-wheeler). This means that the a-arms are actually the same length which is a little better. What I could easily do, is make the inner pivot point of the top arm at the same vertical point as the lower arm and then the top arm would be shorter. Then I have to remake the top a-arms and honestly I'm rushing to finish this up before I head to college in a few months. If I decide that it's really that bad, I will fix it after I've driven it.

This means that the a-arms are actually the same length which is a little better.This means it won't have any camber change - it will all work in a parallel manner, which won't let the front end work very well in the corners. It's gonna push badly and probably have a lot of feedback through the front end.

But, since it's a rush, go for it and change it when you have a chance later.
