Braukuche, the torsional stiffness of the body is a big issue for our cars.
I've done 2 things to help, the Mendeola front end is attached much better than a beam, it connects with the Napoleons hat as well as the frame head, and I have a roll cage with bars coming forward across the doors. I have considered more reinforcement around the the edge of the pan, but I'll test the torsional stiffness before I take that step (weight!)

I saw me Ghia where they welded a steel box beam across the pan roughly under the rear seat.
I always wondered if welding the pan to the body would make it much stiffer? _________________ Go Reds! Smash state!

I think the best solution without a roll cage is stiffening the perimeter of the pan. You used to be able to buy a preformed U channel section to bolt in using the perimeter bolts of the pan. It would be interesting to see how stiff it was if the body was welded to the pan..... big job for some one.
these are the pan stiffeners that used to be available

My "new-to-me" buggy, uses what feels like 3/4" pipe in the channel |

I would be very concerned about reducing the value of my KG welding it to the pan besides the thought just keeps me sleepless
Only for a couple tens improvement on the track?
Just my 5c |
With all the other mods for racing that would be the least of the issues when it came to selling it to someone who wants it stock. _________________ Go Reds! Smash state!

I've just finished making and installing the brake hard lines. I thought I'd show what I do.
There are a few ways to go, you can buy a kit of hard lines and bend them to fit or you can make them from scratch. The are 3 types of tube that are legal in Australia and probably similar in Europe and USA. All of them are annealed (softer than a hard drawn tube).
Stainless, very hard to flare, tricky to bend, looks a million dollars
Steel / Bundy, often coated green, medium soft and flares pretty easily, cheap
Copper - nickel, the easiest to bend and flare and it doesn't rust.
Karmann's use 3/16", 4.75mm.
there are at least 3 types of flare, ours is a DIN bubble flare, so you need a flaring tool to make the flares and maybe a tubing cutter. you'll need to reuse your tubing nuts or buy some new 10mm x 1mm DIN nuts, I like stainless with a big hex SS4285D (DIN) from: https://www.brakehose.com.au/product-category/tube-nuts/
And maybe some bending tools and a special spanner 11 x 10, 11mm end for Karmann's
2 grommets for each end of the pan. I have used 2 sorts, West Coast Metric which is very similar to the original and Wolfsberg West which has a wider slot, rounded edges and is easier to fit

I am able to make much better flares in the copper-nickel, than Bundy, see the photo (sorry about the phone quality)
I also used a joiner to connect my new master cylinder to the old rear brake line. Also from brakehose.com
For the DIN flare they label these as 'drill point'
As it is a race care I have a proportioning valve on the rear line to slightly reduce the rear brake pressure so the front always locks before the rear
On a disk brake Karmann the master cylinder is 19.1, for my bigger callipers I have chosen 23.8....... which may turn out to be a big mistake
I've used a 22.2 from a 70's VW bus in the past which I liked the pedal feel. My new callipers have bigger pistons so we'll see. |

The valve reduces the pressure to the back, it stops the back over braking. |

A good day today, i mounted many of the parts i completed over the last few months.
here is a finished suspension adjuster, all titanium
front arms in
fox shocks, 944 hubs and 911 disks
top view
and bolted on the golf 1 rack with a Quaife quick steer kit

Time for another little update.
I finished the front hard lines
I was able to 'repurpose' some flexible lines from my son's 944 project. He'll just wonder where he put them
with the 4 piston Wilwoods you need a NPT to 10x1mm adapter
this part is finished
I've done a basic wheel alignment starting with similar settings I used on the old ball joint front end. +6 caster, -2 camber, 1/8" toe in. I used more neg camber on the old front end, I'm thinking this more modern design with rising camber will be able to use less like an early 911. |

I can't wait to get feedback from you on how it performs. I've not seen reports of it used for anything other that putt putting to car shows and back. _________________ To err is human, but if the eraser wears out before the pencil does you're a major screw-up. |

Me too, I haven't been racing for 7 years and I miss it a lot. I have not found a single review of a car on the track with this suspension, to me it is way too much work just to go to a car show. I hope to have it all running by Christmas. This does assume no major hiccups along the way |

Time for an update.....
I'm waiting on some parts to finish up the front sway bar, so I moved on to the rear suspension. I'm using '86 944 arms with early 911 disks (solid) with a Wilwood caliper that has a hand brake mechanism
My first trial fit seemed to go well but I couldn't get suspension settings I wanted.
one of the problems with 944 arms in an IRS pan is getting toe in, I want 3mm toe in and 2 - 3 degrees neg camber. I had already moved the inner pivot as far inboard as I could but I still had 3mm toe out and 1 deg neg camber.
So the next cure is grinding the spring plate holes to get the settings I want.
So 3 days later and many trial assemblies I got there. I can get up to 5mm toe in and 2.5 neg camber. I'd love a bit more but as Bugs Bunny said, 'that's all folks'. To get more I'd need to put a camber box on the inner pivot
if you are curious how they look and fit, look up Rebel Racing 911 camber box
(which) I can't seem to insert as a link
here's an arm in with the disk on so I can mount the camber gauge to the disk, and a strap to simulate ride height.

a few details:
I've used a uniball for the inner pivot and cut the VW pivot bolt to the right diameter.
instead of rubber or urethane spring plate bushing, I've used Elephant racing 944 poly bronze bushes. the outers are in cut down 944 housings
and the inners are fitted in a VW bush
finished it looks like

Sway bar next, it's a rebel racing 944 bar that I 'cut and shut' the outer sections to work on a Ghia. It was a pity to wreck the nice anodising
the mounts on the torsion housing are Kersher.
here you can see the rear height adjusters in the middle of the pan just behind the sway bar

last thing for this week I got the calipers on:
and the mount to adapt it to the arm
