I'm planning out the suspension setup for my Baja Bug build and could really use some advice. I'm still pretty new to all this, so any tips or input would be appreciated.

Right now, I'm working on installing a modified class 11 cage and finishing up the interior. The next stage of the build is suspension!

I'm planning on running a 6-over beam with 10" shock towers, +2" arms, and combo spindles up front. Out back, I'm thinking 3x3 arms.

The part I'm stuck on is shocks. I'm not sure if I should run coil carriers with bypasses or go with internal bypass coilovers. What do you guys recommend?

As for your shocks, wait intel you get the suspensions built to find out what your travels are, and how much room you have around things , then go from there,

There is a world of difference between a class 11 cage and suspension and a class 5 cage and suspension. Start with the cage before the suspension. There is little left to a VW chassis in the long travel class 5 world. Even a real class 11 has far more than a kit cage, full length tube chassis and front axle support bars "hidden" in there for example.

The question you need to ask yourself is... What are you using the car for?
High speed desert?
Low speed mountain fire roads?
Looking cool?

You don't need all of that for 85% of applications out there.

What about your current setup don't you like?

Do you have $10k+ laying around for go fast parts? The shocks you're describing are $$$$
Start a list with prices of all and I mean all the components involved to assemble the package that you want before buying anything. It adds up real fast.

How's your tranny holding up? Is it stock?
What's powering your rig currently? What condition is that in?

Your car looks pretty good as is. Or does it just look cool?

The interior is the last thing to be finished. you're going to be cutting, welding, grinding inside the car to mount the shocks.
All of which is done at the end. After all of your drivetrain is assembled and travel limitations are known and set. Only then can you know where and how your shocks will be mounted.

Are you doing the work or is some one else?

Not trying to discourage you. Just being realistic.

There are many members on here who go lots of places with relatively stock bugs. They do just fine.

I have a ball joint setup stock width 6" travel. Stock boxed rear arms 9" travel. I'm more than happy with it.

Exactly what I was thinking! I just wanted to get idea of what kind of shocks I was going to use before starting.

I’m just using the class 11 cage as a base for material, but it’s already tied into both torsions and braced for coil overs!

I’m planing on using it for a little bit of everything, mainly desert car, think Ocotillo Wells and Superstition. Maybe fun daily driver for a little bit too!

There is nothing inherently wrong with it, I’m just ready to upgrade. I’d like it to able to keep up comfortably with the bigger cars in the group I go out with.

Yeah, it’s pretty crazy how much everything costs. I already have a spread sheet to get an idea of the total cost too.

I have a stock type 1 transaxle in it right now, I plan to move to a 3-rib that I already have when the time comes. I currently have a mildly built 1915 in it, it’s only a few years old and running great! When the time comes, I plan to upgrade to a bigger stroker motor.

Thanks man, I appreciate it! It definitely has the look, but it’s all stock underneath.

I meant the interior as in the roll cage, seats, and fuel cell. I’m not sure if this car will every get carpet put back in it lol!

I’m doing a lot of the work, but I have a good buddy helping me with some of a lot of fab work. I can weld, but he is much better than I am at it!

Yeah, I get that! It always surprises the 4x4 guys when I go up the same obstacle they just did! This cars do pretty damm well without much modification.

Thanks for advice, I really appreciate you taking the time to respond to my post!

What’s your guy’s thoughts on micro stub?

Pros and cons, is it worth it, reliability benefits, etc…

Avery,

Good to see your progression pics.

Honestly next I would work on getting that 3-rib in the car. It's going to take a decent amount of work in itself.
You'll need to address if you want the shift rod in or on top of the tunnel. A 10-degree mounting kit will get it in the tunnel for a cleaner install.

Unfortunately you've already built the engine cage. This also was one of the last things to complete.

The 10-degree trans kit gives you more rear ground clearance. Since the engine will be raised up a couple inches. With that kit there will be a large empty space between the sump and the lower tubes of your current cage.
If you go with the kit that puts the shift rod on top of the tunnel, the engine will likely stay in its current location. With no additional ground clearance achieved.

After that move on to rear trailing arms.

I recommend finishing one end of the car at a time. Since the back is more involved to that first.

Start thinking about your steering setup as well. You're not going to use the stock components if you go wider anyways.

as i said before Depends on how much $$$$$$$$ and Time you plan to use.

lay out your priority's, make a list of your wants and needs, finish the needs first then if you any $$$$ left then do your wants, I have pissed of a lot of $$$$ and time changing things if I would have just though it out first.

My plan is to finish the majority of the cage this summer, daily it during the school year(I’m in college right now), and acquire all of the suspension components. Then next summer, start the suspension work!

I’m not sure how I want to mount the bus box yet, but I’m definitely going to use a Jamar box or similar to raise the shifter up to match the seats. So since I’ll have to cut a slot in the floor anyway, I’m not worried about it fitting in the tunnel.

For the engine cage, I was planing on just cutting out and replacing the lower bars when the time came. I wanted to have them in place while I’m driving it through out the rest of the year!

Exactly, that’s why I’m trying to plan everything out from the beginning, I want to avoid redoing stuff as much as possible. I was just curious what the benefit of a micro stub is? Is it just increased travel, reliability, etc?

Close AI answer

Key features and benefits:
Compact design: Micro stubs are shorter than typical VW stub axles, saving space and allowing the axle to sit further inward.
Increased strength: The shorter design can improve strength.
Improved CV angle: Micro stub axles can allow for longer axles with less CV angle, leading to more wheel travel.
Removable design: This allows for easier replacement in the field if needed.
Full floating bearing assembly: The bearing assembly mounts to the trailing arm, allowing the wheel to stay connected even if the micro stub axle breaks. This means you can still tow the vehicle in case of a broken axle.
Conversions: Micro stub kits are available to convert various VW models with IRS suspensions to use larger CV joints like the Porsche 930 or 934. These kits often include forged chromoly stub axles for increased strength.
Cost: Micro stub axles can range in price, with some models being more expensive than standard VW axles.
Considerations:
Compatibility: Ensure the micro stub axle kit is compatible with your specific VW model and suspension setup.
Installation: While micro stubs offer advantages, proper installation is crucial. Some modifications or adjustments may be necessary, as mentioned in a video about a Baja Bug installation.
Potential modifications: You may need a proportioning valve if you install these, as the rear brakes might lock up before the fronts otherwise.
Bolt patterns: Kits are available with hybrid bolt patterns to accommodate various applications.
Examples of Micro Stub Axles:
EMPI Race Trim Micro Stub 934 Stub Axle: This forged chromoly micro stub axle is designed for Volkswagen and VW-based dune buggies.
EMPI Microstub for 930 CV 33 Spline: Another forged chromoly micro stub axle designed for use with 930 CV joints.
Jamar Performance 33 Spline Chromoly Midboard Micro Stub Axle: This micro stub axle is specifically designed for use with Jamar's MID-BOARD micro stub wheel hub and bearing housings.
In summary, VW micro stub axles offer a way to enhance the strength and performance of off-road VW vehicles, providing a shorter, more robust axle setup that can improve wheel travel and provide a safety benefit in case of axle failure.

What axles do you guys recommend I run? I was planing to use 930s, but I’ve heard talk about 934/935s?

Your first VW and you want to redesign the entire thing from day one? You've come to the right place because these guys love spending other people's money vicariously.

Whoever chopped the body at the engine bay needs to be shot.

You're talking like doing the work is a weekend project.
It's not. The folks who can do it that quick have done it many times before.

The racecars you see on the internet are designs that were thought, tested and proven out. Not a bunch of Chinese parts cobbled together in a couple weeks.

The extra time taken to do things the right way and in the correct order will save yourself headaches and money down the road.

Of course you will do you and do it your own way. Its your car.

Expect the car to be down and on stands for a few months at least.

You can save yourself some cash by shopping for used parts. People are always selling old racecar parts.

Yeah I know, that’s always how it goes. I’ve put together a few rails and some stock-adjacent bajas before.

I’m just trying to figure out all the parts I need so that I can start buying them off marketplace or the classifieds when they pop up.

Hopefully reduce long term downtime by splitting it up into multiple parts.(cage, rear end, and then front end probably)
