I have also done something similar.....on the front of a type 3, i used the front discs with 5x100 bolt pattern then machined off the brakesurface so they would fit in a rotor from a 2001 jetta 2.0 then fabbed up brackets and used a caliper from a 96 jetta 2.0 and voila........bigger brakes w/floating calipers using al stock vw parts! (except for the custom bracket) http://www.franklinsvwwerks.com/phpb...760&highlight=

hey guys,
would this work?

if i used a stock vw 4 stud disk or drum machined down to use as a hub with a porker vented disk, then have the 4 stud vw pattern put into the disks. a early 944 caliper and mounting bracket.

i want to keep 15" vw pattern wheels...

cheers

Hey Mabbo,

I've got a set of early single-piston sliding calipers if you're interested.

hey dorigtt
i guess the postage from america would be a fortune, im in the uk so would probrally be easier/cheaper to get some from over here...
cheers for the offer though.
mabbo

Naw! Postage is nearly free... I'll just scan them and email them over to you:D

Is this the one you're on about? My mate did it to his Baja and it works a treat. The vehicle gets some hammer too and it seems to be holding up well.

:)

can anyone see why this wouldnt work?

vw 4 stud drum or disk machined down to use as a hub
get a 944 disk re-drilled to 4 stud vw pattern
bolt the 944 disk up to the back of the "hub" like Steve C's method
regular 944 mounting bracket and single slider caliper

this should give me vented disks and still use vw 4 stud wheels?

mabbo

Steve your set up looks nice :)

can i ask - are the studs fitted to the hub, or to the disc, then go through the hub?

And what studs did you use?

Thanks

Dean

Hi

If you look closely at the top photo you can see the outer piece is a stock beetle disc with its braking surface removed, then you can see a thin aluminium spacer between the cut-down stock beetle disc and the Porsche rotor.

So to answer your question, I just used high tensile studs screwed into the threads in the cut-down stock beetle disc with a dab of Loctite to hold them in.

Steve

PS, there is a seller on Ebay Australia who sells these high tensile studs called "vforceracing".

thanks for that info - so the wheel studs are just put into the old beetle disc - awesome. you have been very helpful - thanks. oh 1 more question - which disc would you suggest is best to use as ive noticed they come in different heights!

Hi

No worries. Those discs are from an early 911, they also fit 944 (1982 - 1989), 911 (1969 - 1983) E,T,S,SC & Turbo.

You can download a brake rotor catalogue from here www.dba.com.au It has all sizes and heights listed

Steve

dont suppose anyone has the dimensions you need to machine the beetle disc to get the same as the 944 T hub?? and when i have it machined what i needto shim out by?? Cheers anyone

Interested in that info too.

i have been working on a conversion fitting 944 late discs to bug hubs and am keeping 4 stud bug pattern. you need to fit a spacer between the hub and the inside of the 944 disc depending on your application ~5mm.

i had a bloke i know machine 4/130 into the porsche disc - fits ok and you only end up with 1 hole with a thin land ~5mm. i made press fit spacers to the hubs which align the disc concentrically ensureing no issues.

haven't finished the caliper bracket yet......

using ibiza cupra calipers on mine 54mm pistons.
