Mk3 golf hubs on mk2?

There are a number of ways to do it using various combinations of parts.

Easiest is the way you have said, but it depends on which mk2 you have and which mk3 you get the brakes off.

I think the rear disks are all that need changing on the rear.

Best bet is to have a search on clubgti.com

Cheers Dez - I'm planning TT comps or something similarly large, but could probably do without any track widening, really.
So basically I can't just slam the front hubs onto my wishbones, slot my shafts in and keep the same track and roll? curse word.

When taking the engine out of we just cut the driveshafts because it was cold and some idiot had been at all the inner bolts and rounded them off. I have the outer CV joints if they are any help?

Could I press the 5 stud hubs into the 4 stud bearings? I don't have etka to check the sizes anymore.

nah, the front hubs don't go onto the wishbones cos the balljoint is a different size, but you cant swap the balljoints over as they bolt up to the wishbones differently.
its has been done by use of various adapters, machining and cut and shut bits, but its a lot of dicking around, plus I think the geometry of the steering arm on the upright is a bit different too so it gives squffy handling.

from memory, you can swap over inner CVs between shafts, but not outers- so long shafts are essentially tied to big CVs and therefore 5 stud hubs, and its possible to go wide or narrow with 4s using the previously mentioned passat setup)
I think inner CVs come in 100mm and 108mm sizes.
generally if youre doing it you want to keep each respective wishbone with its associated driveshaft too so theres no issues length wise there as ive seen people get em mixed up and fit too long shaft, and it breaks stuff- lots of stuff.

the hubs/bearings/uprights are not interchangable at all, so you cant put 5 stud hubs into 4 stud bearings/uprights.

also, you cant just drill your 4 stud hubs to 5 stud and fit the bigger brakes- the disc offset is different, but the wrong way- the 'hat' is taller on the 4 stud ones so you cant space your way around it.

I have a full set of mk3 gti kit in boxes here including 288mm brakes if you are going to do it- ive got some uncut driveshafts if you need em.

the two options are basically- go wide, with 5 stud and bigger brakes. or if youre not bothered about the bigger brakes, jsut buy a pair of adapters. itll obviously be a bit wider, but not as wide as the above option. you can then just chuck your 5 stud discs on the back which is a half hour job.

Thanks for that link, I missed your first post!

It's a lot to take in because it seems to be focused on wide tracking rather than going to 5 stud (I'd rather keep the narrow track and just bump things out with spacers or wide wheels!)

So, my late mk2 hub carriers will take the early mk3 hubs, like you say, although GSF list different wheel bearings.

Is the "offset" of the hub the same as the 4 stud hub? - If so, I'm happy to redrill my existing disks and stick with 239mm brakes (Or mk5 polo 1.0 disks look like they are close enough to fit, 2mm narrower and 1mm out on the offset but otherwise the same, but in 5 stud)

Oh, interestingly (or not), brakepart list the same disk for an early? (92) passat VR6 as for a mk3 golf GTi with girling calipers - 280mm dia, 22mm thick and 28.2mm overall height, at £17 each)

I could, but they are
a: £90 a pair
b: 15mm thick

My mate is about to send a mk3 gti over the bridge, so if the stuff swaps over I can convert it for free/cheaper without losing 15mm of arch clearance
