Yeah thanks I've done a bit of googling but thought on here would be the place to
get some info on decent bolt on kits and the NOT so decent kits available.


Cheers

I know CBB do a bolt on kit for beetles and if I remember it was based on commodore calipers. Not sure about the 6 stud though. Easy enough to get blank rotors for a bolt on kit that can be drilled out. Also I remember chatting with someone on AVD who used to do that stud pattern. Sorry but can't remember their name ATM.
Good luck with the search.

Try talking to VWCOOL, he has a great kit. He may be able to make it suit a 6 stud disk for you.

Blank rotors for the front isn't an issue as any of the Oz, UK or USA vendors should be able to help with them.

Rears ain't so easy. Only company I can think of that can make custom spilned rear hubs for different bolt patterns is these guys Airkewld rear brakes

Maybe CSP can to a special order too if you ask them.

Hmm, but how strong do you think the splines in them are? Where/who made them for him?

I've seen some rear hubs break when converted to LC 6 stud as the casting was weakened when machined for the wheel centre diameter. I know Bob Mobray of Rivmaster does it but they are high dollar racing units with alloy hubs etc and I'm unsure of road going legality.

I have a feeling the pcd gets close to the wall of the disc hat and the stud head may have clearance issues, so be sure to check.

Hopefully Rod can help

What about using the screw in studs, no need to spot face the back and leave more meat.

Screw in studs are unsafe and should never be used....... My opinion again, sorry 🙂

I swear most people must fit the screw in studs with Clag school glue, they always seem to unscrew out with the nuts.

I used red loctite on mine and the loctite primer before fitting with no problems and everyone knows how often my wheels get changed.

It's the unknown factor Joel. The stud can get tight in the nut and come out of the drum, this can happen and if not addressed the stud can work into the nut further and have less thread into the drum, the other aspect to this is that as we know, the VW drum has more meat in the webs where the studs go. This is because the threads into the cast iron drum need to be longer for enough strength. When you restud into a 5 stud pattern you miss some webs so the threads are not strong enough any more and will fail when subjected to enough force.

You may not have had the problem, yet. One day you may be loading the suspension by avoiding a concrete truck and similtaineously hit a pot hole and have our wheel studs break due to pathetic cheap studs failing and end up under that truck......the point is, it is not sound engineering.

For me, proper studs pressed in from behind is the only option other than stock.

Matt, dont get me wrong, I'd always recommend press in over screw in I was more making the point most people dont fit the screw in ones properly, you often see them unscrew out with the wheel nuts.

I should have been a bit clearer, mine isnt those crappy glue in empi straight studs they are high tensile bolts screwed in from the back side of the hub so they cant undo and pull out and loctited to make doubley sure they wont move.
I'm still 4 stud, they go through the strengthening ribs.

I agree matt, but i would rather have a bit more meat left and check the studs as they are torqued up than have a disc failure at speed cause of a thinly machined press in stud on a shit casting.

I bought some rear hubs off a reputable vw mob that were about 6mm thick where the studs were to be fitted. Needless to say they are on the shelf as a reminder not to trust anyone!

Nothing wrong with screw in studs, if they have a full thread engagement, are off the same material and are fitted a as Joel suggested, therefore will have the same strength as the standard lug bolt,, I run them and never had one come out or change position, just fitted with 609 super retaining compound along with the correct primer, you would have to heat them up to get them out.

Hi guys

Unfortunately Rod was unable to do the 6 stud rotors so I am getting Paul from Steel Art up in Brisbane
to do me up a set. He has done a fair few sets of brakes with 6 stud Cruiser pattern so I just need to
be patient as he machines them up.

Hi psimitar

Was about 800 with 2 new front rotors, I'm not 100% sure yet! I'll be speaking with Paul at Valla and get an
exact price.
