It takes $$ to build a rear suspension to do that, and $$$$$$$$$$$$$$$$$$$$ to build up the rest of the car to a point where you can use that travel.

Is this a hypothetical question, or are you building a race car? If your building a race car, I would love to see pictures. TheSamba needs more race car builds. Lately I have been going to RaceDesert to get my off road race car fix. Laughing

Oh, and, you are looking at 5x5 rear trailing arms, coil overs, axles, 934 cv joints, and micro stubs/bearings to be able to handle the stress.

Thats just the basic suspension components. This will require a ton of fabrication to strengthen the rear torsion, or better yet, just cut it out and build a custom rear end to support the suspension components, engine, and transmission. Then you have to beef of the chassis so that it doesn't crumple when you cycle 20 inches of travel. Lots of tube bracing and cage work. Basically you will end up with a tube chassis with a vw pan and body...and to make any of this worth while the front needs to be built up too. 4 or 6 inch over arms as well as coil overs, a custom beam tied into the cage, a rack and pinion steering system, tie rods, beefy spindles...don't forget an engine and a beefy race prepped 091, vanagon, or mendeola transmission to put power to the ground...

20 inches is a LOT of travel for a VW based vehicle. Just something to think about. It's not as easy as just building a long travel rear suspension. The dollars add up fast to build such a set up. 20 inches is full blown race car material, which again, I would love to see.

If i was building a race car that would be awesome BUT im asking this because the first ever baja bug i rode in was the TROPHY BUG. Awesome i know but now im spoiled and when i do stuff i dont want to be like oh look here is my baja bug that looks and preforms exactly like that one over there and there and there and there. I want people to look at the stuff i build and have there jaw drop and then say that is the most bad ass thing i have ever seen ever.

Let me paint a picture for you of what im like so im in high school and we have to do a controversial speech and i watch 30 speeches of people standing there not moving no emotion and no excitement. So im like lets make this interesting so i go up make a lot of noise and give the best speech ever. im walking around class talking throwing note cards, doing long math problems that make no sense at all, being funny and stupid. i bowed at the end and all that good stuff and you know what i got an A.

So yeah that's i want to do over the top stuff im actually kinda know for that i guess

Sounds like a really really cool project. With enough time and fab skills, you could pull off something that would knock the socks off most people.

When your done, take it out and put the smack down on the dude talking up their lifted pickup trucks. Laughing Laughing

My uncle has a lifted F350 with 35 inch nitro tires and my cousin 13-14 looks at it and sees a full blown trophy truck and every single time he brings it to my house he drives it up a 1 foot hill and says Show them what a real truck can do. Of course then I get in our Chevy traverses (look it up if you dont know what it is)and take the same hill and he still says look what a real truck can do

This is 18 inches of travel. 5x5 arms, 25 degrees on the cvs, and 4 inches of ground clearance at bump.

5x5 or 5x6 arms should give you room for 20" my friend's 4 seater has 5x6 arms and VW hubs on torsion bars.

Of course you need a tubular framework (cage) to support this sort of suspension. Crumco is probably the most cost effective way to get this suspension setup. They build them all the time and 20" is their standard under a Bug body shell.

Richard (aka Dustymojave) knows his stuff. If you have questions, he has an answer, or a darn good opinion. He has been involved in the off road race circuit for longer than I have been alive. I always respect his opinions.

The other thing with getting 20 inches of travel is you need some tall tyres to actually be able to use the compression travel without the pan just hitting the floor - so the CV's, shafts and transmission all need to be up to the job of swinging big tyres. We run 5" longer rear arms and with 31" tall tyres, there's no chance of using the full compression swing, not even close, we end up with about 16-17" max.

What would happen if you went up to 32s or even 33s would that give you more clearance or would you just hit the wheel well

I am getting 18 with 33's. There are still 4 inches of ground clearance at bump. If I bump an inch lower and push the limits of the cv I can get 20 inches out of a 5x5 with 33's

We need to look at how they built the trophy bug and got 32 inches of rear travel

Not possible. You will never get 32 inches of rear travel on a vw style suspension.

It is possible with a linked solid axle

Here is a "Trophy Bug" check out the specs.

The silver one from Kreger Fab can't touch this bug suspension wise.

The Kreger baja was owned by a friend of mine in AZ, I have been in it, and out offroading with it. It DOES NOT have 32" travel. I would guess 20" at the most in the rear, and probably close to the same as the front. It is though, probably the nicest Baja's ever built.

I race in a Class 1 Jimco, it DOES NOT have 32" of travel either.
