Sub framework....the VS / JPS framework is almost the same configuration as CMC FF etc. They are solid and well engineered.   The super wide body speedster I had was hit on an angle by a Escalade . Despite the fiberglass looking worse than it was, the box frame work held up very well with a minor 3/4" pull needed at the driver's side kick panel base.

This stream of safety bits about our cars reminds me of when I was learning to drive, (officially & legally) with my dad. He was a great educator and a Dr. of Laws, high up administrator of our schools system, etc. He said, "as you enter the drivers door each time, picture yourself climbing into an eggshell."   And, he followed it up with a basic law of physics saying, "no two pieces of matter can occupy the same place at the same time!" 

So, in short, "don't drive like your in a bumper car at an amusement park!" 

Happened on an accident that I wish I had seen happen.  A Corvette was hit in an intersection and apparently started spinning.    Pieces of all the exterior body panels were in the street at all points of the compass.  The unhurt and very perplexed driver was still behind the wheel sitting in the remains of his car.

Are you doing the welding ? Don't forget to fabricate and install a Kafer bar set up Brock. How bout running a nice straight piece if 1/2" conduit front to rear for the wiring ? Steel fuel line or copper ?

I like that you're going to cut in seat pans later. Think about seat belt placement and reinforcement for them. Will you have a roll bar ?

Nice work so far Brock..............Bruce

Bruce, yes I will be doing it all welding, engine , body paint, interior ect.

Kafer bar? Never heard of that, please explain.

Seat belt will be done after seats, retractor will be bolted to the chassis, shoulder to the cage and latch to the tunnel.

Good idea for the wiring conduit! 

Stainless fuel line if i can find a piece long enough. 

Thanks for the help.

Brock: It looks great! I used Por-15 on my chassis when I welded it all up in the early 80's,  It still looks good and has not been stored in heated garages or even always under full cover!  Just a suggestion. I have used it on old Bugs and Buses that I have restored to good success. I have no money in the game, just like the product!

P.S. Be sure to wear gloves!  This stuff gets into the pores of your skin...

Wolfgang,  it does have steel inserts in the hinge area of the body and doors. It does not come mounted though and i am still figuring how to drill the door correctly.

Right now i am thinking of setting my gaps and use a lil bondo to glue the door to the hinge long enough to drill. The add a nut plate inside the body for minor adjustments.

So does the coupe not have the huge inner rocker panels that pan based speedsters have?  Those huge inner rockers always bother me on the pan based speedsters. I understand why they are that way to expand/make wider the beetle pan.  Just don’t know why no one ever thought of just going with ghia or type 2 pans and making that inner rocker more like a real 356. 

Well ,that is why if your going to bother welding up your own pan you could expand the floor area and make the sills the right size and then you will have more width to accomodate better seats etc.  I don't know why one would not contemplate doing this at this build point.  

IM and SE, have wider interior space including foot wells and it helps if your feet are size 12 or more... Feel free to disregard all comments.

BTW enjoy the build we will enjoy it as well.

You can even look up and there is a pedal cluster that seperates the clutch from the brake a bit more for wide feet and they can even put a roller for the gaz pedal if you want.  (your choice) 

Actually, it is a pretty cool setup as they even reinforce the clutch set up HOOK with an even  stronger clutch arm to prevent breakage.   

Anyway, tremendous possibilities for big feet.  

Hi Folks,   Some builders choose to make their own chassis.   I have had a square tube subchassis designed that is rigid with a Beetle pan that is shortened.  The subchassis can also act as a template for the builder that is shortening his own Beetle.  This has proved  efficient in Canada and Australia where it is much easier to modify an existing licensed VW instead of going through the special build process there.

The lateral "wings" on the subchassis match up to the rocker panels in the Coupe.  I bond into the fiberglass  a steel plate that is 36" X 3"  X 1/4" into the rocker panels so the body can be bolted to the subchassis /chassis on the outer part and the chassis can be bolted to the inner part of the "wings".   For heavier usage/ racing, I have a tube chassis which is more rigid.

Yes, there are steel plates bonded into the fiberglass on the doors and the A pillar for strength in mounting the doors. The best way to mount hinges ( as Brock figured out)  is to glue hinges in place and check the door fitment prior to drilling and bolting on of the body.

Hope that helps with the questions asked.

Cheers,

Dr. Chris

Michael,  Bruce Thanks!

DWP , thanks but removing the beam is the last thing on my mind. I want this car stiff, the beam will most likely be welded to the lower part as well. The rear torsion tubes are alreay welded to the chassis on the ends and will also be tied in with the cage at the top of the shock mounts.

Here's photo of the lower front beam supports that DWP referenced.  They are an easy add on to any Speedster or dune buggy.  Made by Empi but not much for them to screw up. Easy bolt on but may interfer with front bumper brackets. The second photo is of their upper ones which probably isn't as easy to install on a Speedster.

CSP has a version too --- but much more $$$ - $199 Euros (and higher quality).

A further note on caster- ball joint Beetles came with 2' 30" (+ or - 30") caster while Porsche Speedsters had 5'. VW front suspensions, when lowered by adjusters, Select a drop or cutting tubes the car will LOSE caster and it can become a bit of a handful even at legal highway speeds and downright dangerous as you go faster. I have personal experience with this, at one time having built a Cal Look bug that was work to keep straight at 60 mph and was almost uncontrollable at 100 mph. I knew nothing about caster 35-40 years ago.

For a car to be safe at higher speeds there needs to be more caster than stock. Most people here that have addressed this run 5-6' caster. Normally this is accomplished with shims under the bottom beam. Gene Berg Ent. caster wedges http://www.geneberg.com/cat.php?cPath=12_384_2917 are 5.9 mm (.236") thick and will add 2.36'. If you're welding the front beam in don't forget to take this into account.

Hope this helps. Al

The car will only need 2 sets of shims if it's lowered a fair bit with only adjusters or cutting the beam. Using 2 1/2" drop spindles doesn't change the caster, so even if you lower the front a little more with the beam then 1 set of shims is usually enough to get it safe at higher speeds. Usually this is checked when the car is complete and it's getting aligned, so if you're intent on welding the beam in place, be sure of where you are before committing.

The issues with drop spindles- they add 1/2-5/8" track each side, which some people don't like. There seems to be enough fender clearance in most instances. There are also some cast aluminum 15" wheels which just touch the bottom ball joint area. IIrc some Rivieras have this problem. I have heard of guys managing to clearance the area in question to fit. 

Yoda out (for now, but know you can't get rid of me!)

Brock:  All of the shim sets I've seen are about 1/8" thick, which gives you 2-1/2º to 3º of increase.  How many you use depends on where they get your caster to after install.  On my last alignment, adding a second shim on one side wasn't quite enough but a third shim was too much so we cut a segment out of a piece of electrical conduit (about 3/16" wall) and there we were.

Most set-ups run two per side (or one 1/4" I guess) behind the lower torsion tube to get you to about 5º - 7º of caster.  If you have a stock of thin-wall steel tubing (pipe) with the same ID as the OD of your torsion tube, you could make a set yourself - there's not much to them.

On a lowered car, they will greatly reduce bump steer and wandering at turnpike speeds.

Drop spindles would change caster because the front of the car drops relative to the back.  The change in angle would offset some of the existing caster.

A piece of a pipe wouldn't be the same as a shim.  A pipe has a different radius inside and out.  A piece of pipe would have a uniform thickness.  A shim has the same radius on both sides - it matches the tube and tapers toward the edges.

Looks like the same folks make them all regardless who you buy from. I bought mine from Gene Berg. They were the only vendor who knew how much angle a shim added; I believe it was 2 degrees 36 minutes. When installed I wound up with 6 degrees and change. Gene's shims are about 1/4" thick in the middle.

I don't have drop axles. To get the handling where you can drive you'll have to install a front sway bar and a camber commentator on the rear.

That's all I know about the subject...

Did you press them in or someone else? I ask because there are notches that have to be lined up for the ball joints to move freely. Failure to do this will create a very stiff suspension, as the ball joints won't have proper movement. The first pic shows the notches properly aligned when installed.

The 2nd pic shows an improperly installed ball joint, and how it has self- destructed.

You'll find that a lot in the VW aftermarketplace- most people will tell you "just use this; it works!" while Gene Berg put the effort in to understand why, and probably (a lot of the time) did the original r&d and originated the part or brought it to the VW world in the first place while everyone else is opportunistically making a buck off something they put no initial investment into. Al

PS- For any one doing the initial alignment on their car- read again what Greg (@WOLFGANG) said just above. The alignment guy, unless he's an old VW guy, won't even know what caster shims look like, let alone have a set on the shelf. Be prepared, and if you don't use them they'll sell here easily. Or, for the less than the $15 or so they cost,  keep them in the garage on the work bench as a conversation starter ('cause I'd put money on no one else knowing what they're for!).

Ok, NOW I'm leaving...

Ray, thanks ...waiting for the spring and bushing kit and the new output seals.

Todd, lol its this or mow grass lol......

Actually i mowed this morning for an hour to.

Are you retired?  My tentative retirement date is 7:30 am, March 1, 2021.  But then, who is keeping track?

My job has this irritating aspect in that it interferes with my life.
