Well, I'm on my third sandrail now and I'm still not satisfied. I can't afford a high digit rail and I can't see putting anything more into my current sandrail. The past couple trips have been cold and windy and I found myself having more fun cruising around in our Jeep Cherokee Sport tow vehicle than the rails. With all the comforts of an enclosed vehicle, I could see myself doing a lot my dune runs regardless of the weather.
That's how I came to thinking about a Baja Bug for the sand. I haven't seen many out there (in fact, I don't think I have seen any out there) which would make it a little unique at least. Also, virtually every part used in sandrails are designed for VWs to begin with. So it should just be a bolt- together affair (Right?

).
So heres the plan:
Starting with a stock Beetle...
- Pull all the fenders off (won't need them for sand, cuts down on weight, no tire clearance problems and this will be a green sticker vehicle anyway)
- Cut front end off. Install Baja hood and front panel
- Install new wider beam with longer travel towers and longer trailing arms (Shooting for 12"-16" travel up front)
- Convert to Bus Tranny
- Install 3x3 boxed trailing arms in back with 930 CVs. (Shooting for 12"-16" travel in rear)
- Dual-Rate Coil-Over shocks all the way around
- Install 2.5 Subaru (maybe with turbo)
- Install Roll Cage
- Install Bucket Suspension Seats up front and maybe in back (I want to keep this a four seater which makes the roll cage difficult)
- Install front and rear disc brakes
- Put on some 6.80 Apex tires op front and Hole-Shot paddles in back
- Install 5-point seat belts.
- Give it killer paint job.
- Add-up all receipts
- See Doctor about recovery plan from recent heart-attack
After much deliberation, research and preparing the garage to be an adequate work environment with adequate tools, I went on a search for a used beetle. I didn't want a Super Beetle because the mcpherson struts used in those are unusable for off-road. Also, some '71 and later and all '74 and later beetles use the struts. I didn't want a swing-axle which are on all '68 and older beetles.
So that means I could look at all '69-'70 and some '71 to '73 beetles.
After searching the Recycler and checking some of them out, I ended-up buying a '71 beetle last Saturday for $1100.
It's actually in a lot nicer condition than I needed. The people I bought from where in the process of restoring it. They just put a new red paint job on it, new seat covers, a new carpet kit, etc. I didn't dare tell them what I intended to do with it and all the time they spent on it. The motor actually ran. It's pretty much stock. I don't know what size it is but it's a dual port. Could come in handy on one of the other rails.
It was hard tearing this thing down bacuase it was in such good condition but you can't make an omelete without breaking some eggs. Right?
I'm starting with the front-end first. Turns-out the new front beam I want to install is Kingpin and this beetle currently has a ball-joint front end. You can't just swap the beam because the ball-joint beam has wider spaced tubes so you have to cut-off the front clip and weld-on a new kingpin front clip.
So I bought a new clip but I changed my plan before installing it. I don't think a clip is strong enough by itself for what I want to do. Also, the replacement clip I got isn't as strong as the original. Also, I think I want to install a rack in between the beams to minimize bump-steer.
So now the plan is to cut the top part of the existing clip where it attaches to the top tube and leave the bottom part where it attaches to the bottom tube. This way I still get some strength from the clip but it will be clearenced for the rack. Then I'm going to run some tubing from near the end of the beam tubes back to the fire wall (both bottom and top tubes) where they will attach to the roll cage on the other side of the fire wall with angled bracing back to the floor pan. This should give me the strength I'm looking for.
Before I do all that I need to install the fiberglass baja hood and nosepiece I bought for it. I already installed the hood. I just need to install the nosepiece. Of course the baja kit I got doesn't have any instructions so I'm still trying to decide where to the existing nosepiece off.
Also, since it's clear now that I will need to do a completely custom roll bar, I went out and bought a new welder (my old one was junk). I got a Millermatic 135 and a bottle of C25 shielding gas. I was playing with it last night and the setup welds awesome beads.
Meanwhile, I have been looking at new front beams. The standard wide beams is "6 wider for about $180. I want to increase the track as much as possible (front and rear) for better handling. I want to be able to park sideways on the steepest hill at glamis and not even be concerned about it rolling. I don't think a 6" wider beam is enough for me. I found a 9" wider beam at McKenzies but they about $300 for it. Also, I need to make sure the shock towers will work with 2" coilovers and not bind. I think I'm looking 10" of shock travel in the towers.
Also, I got an idea how to make the rear-end even wider. Mckenzies said they have a kit that extends the existing IRS torsion tube about 3" inches on either side. It sounds like it's a 3" tube with end plates on both ends. One end bolts to the IRS end plate and you attach the swing plate to the other end with an end cap. Then you need to move the inside mount for the trailing arm out about 3". Also, the extended ends would use a wider bolt pattern to accommodate 4" of additional swing plate up/down travel. If it's not like this from McKenzies then I will make my own.
This should give me about a 12" wider track in back (3x3 trailing arms + two 3" extenders). If I do this then I'm not sure if even a 9" wider beam will be wide enough. I can get a custom beam but that will cost $$$. I'm thinking if I could find some chromolly tubing with exactly the same ID as the beam tubes, I could make my own front beam for a lot less and as wide as I want. Make my own shock towers that will work for 2" coilovers and stick in some needle-bearings and bushings.
Then there is the matter of front trailing arms. It looks like stock trailing arms are about 6" long and the standard longer arms are 2.5" longer and 1" wider and are about $200 for all four. So 8.5" long total. That means if the arms could travel 180 degrees (straight-down to straight-up) that would give 17" of travel. It looks like (in practice) they could travel from say 1 o'clock to 5 o'clock but I don't want the beam to bottom out on the ground so they should stop at 2 o'clock which would be about 11"-12" of travel?
Then they have 4" longer arms. Mckenzies wants something like $500 each! for those. I think there are some cheaper ones out there but I don't want to bend them in a witches eye. I'm thinking maybe I could get the 2.5" longer ones, cut them in two, slip the pieces into a thick walled chromoly tube thats about 8" long and weld them back together. That would give me 10" arms. I don't know about cutting some brand new arms in half though. Has anybody tried this?
I hope to get some work done this weekend but my girlfriend decided to remodel our bathroom and I think she's gotten in a little over her head so I need to help her finish up this weekend.
I will try to keep this post updated as I go along.
Of course, any suggestions or recommendations are always welcome.
