Tnx Jim.

Yeah, don't remind me... No gains without pains right? The fresh air supply will have to be rerouted some way as well...

Indeed......without pain there is no gain!!

This is a picture of a friend of mine and his project and how it looks like after the surgery....it might helps you!

Wally · #**273** January 14th 2010, 04:20

That is way too nice!

As one who had asked about cages a while ago, this is great additional info for me. Very nice! Thanks.

Wally · #**275** January 15th 2010, 16:58

Received the uniball bushings and the polybronze ones today

They fit VERY nicely and precise!

I think I will try to fit the inside polybronze bushes as well as the inner circle of the 944 and bug torsion tube housing look to be the same.

Nice, I'll be interested to hear how you get on with them!

I'm officially jealous

ricola · #**278** January 16th 2010, 07:13

Just a thought, will these inner uniballs work without mods on a bug chassis? I know the inner bushes are normally different but can't remember how exactly...

Also, what overall spring rate do you have at the back and how do you find it? I'm trying to work out roughly what springs to get for some coilovers in addition to the stock torsion bar...

Xellex · #**279** January 16th 2010, 10:30

also, it looks like the hole through the trailing arm bushes is too small. Are you using the stock beetle bolt, or the porsche (thinner) one?

Nobody tried that afaik...I noticed the outer diameter is (about?) the same. Difference is ONLY that the bug's torsion tube had 4 indentations (sp?), but I guesstimate that these urethane outer parts don't really need a 360 degree contact path to seat against... Only one way to try it right?
I had also ordered a set of bug IRS black urethane grommets, but Topline was out of stock at the moment and I want the arms back in... so I'll try the 944 parts first I think.

Your quest/questions are the same as I have Richard...
All I know is the former 23.5mm bars were too soft for my heavy tranny/engine/intercooler/turbo and all that, so the logical next step was 25.5mm.
There is no more science to it than that

Test and try, test and try.. Its a bitch, but someone has got to do it

I don't understand the q...

Xellex · #**282** January 16th 2010, 12:40

well, you know how the beetle trailing arm bolt has a bigger diameter than the porsche one, and that you need to pull out the porsche bushings and replace them with the beetle ones, to make that bolt fit through.
Now, from your pictures, that hole looks to be too small to use the beetle bolt. That's why I was wondering, if you made some modification to your chassis, to be able to use the porsche bolts

Ah, yes, now I understand what your saying: yes, I did convert to the 12mm Porsche 944 bolt by welding in 12mm nut(s) deep within the forks

Wally · #**284** February 7th 2010, 13:06

This weekend I have welded in the cage. Its not 'bolt-out' anymore, but the extra structural stuffness by welding the A- and B-pillars to the cage had my priority

Cage is really close to the A-pillars which I really like. It makes welding easy.

I made a bracket to bolt to the former seat belt mounting points so I can keep the head liner and inner trim intact:

Next making the dash fit...

looks like you;ve got your hands full there wally - the poly bronze bushes look interesting - im keen to know how theyl turn out for you this year

ive just fitted the weltmeister (sp?) ones to my spring plates - theyl do for now

out of interest have you considered uniball / coil over set ups.....i like the idea of the adjustability.

keep up the good work
