How to make a 4 stud a 5 stud?

[Jamie5 0]

Hi guys, my friend was selling a mark4 golf, and he gave me his alloys off the car before he sold it.

As you will know, these alloys are 5 stud and i have a 2 L Corrado.

Just wondering what's involved in making these fit my car?

They are nice alloys and of course free lol

 

By the way the reason i would like these on my car is they are not standard Golf alloys, they were after market ones.

 

Any help appreciated.

Cheers,

Jamie.

To do a proper 5-stud conversion is quite involved and you will need the following from a Corrado VR6 or Mk3 Golf (8V or 16V) GTi/VR6:

 

Front calipers and carriers (280mm or 288mm) and the relevant flexi hose.

Front bearing housings and hubs

Front ball joints

Front wishbones

Front driveshafts

Front CV joints

Front anti-roll bar

Front anti roll bar links

Front discs (5-stud 280mm or 288mm)

Rear discs (5-stud)

20 wheel bolts

 

Daves16V managed to do a 5-stud conversion on his car in a slightly different way but I know he had a bit of trouble working out the compatibility of the 4-stud/5-stud components so I've just listed all of the bits that will definitely work and fit your car.

 

I'm converting my 8V to 5-stud while doing the TDi conversion as it made sense to do it at the same time. However my winter wheels for last winter were a set of 15x6 Bora steelies in 5-stud flavour and because I hadn't carried out the 5-stud conversion at that point I invested in a set of adaptors:

 

Adaptors

 

These basically bolt onto your 4-stud hubs and then allow you to bolt 5-stud wheels onto them. They're TUV approved and I didn't have any problems with them over the winter, however they need looking after and because they're made of aluminium you can't swing on the wheel bolts otherwise you risk stripping the threads out of them.

 

They are a cheaper and easier of way of converting your Corrado to 5-stud but obviously doing the proper conversion is preferable. Incidentally the 5-stud VR6 Corrado's and Golfs had a 20mm wider track than the 4-stud cars so 20mm thick adaptors are ideal...it means the car will have the same track as a VR and therefore you can fit wheels of a similar offset without worrying about any arch rubbing etc.

 

Hope that helps..think I covered everything.

 

Cheers

Dave 16V did a conversion and write up, see link:

Yes I did it to my old 16v (now owned by Laser Mark). The only 'specialised' process was getting the hubs turned down which I was able to do at my work. Although I think you can buy the correct hubs that were fitted to the Passat VR6 which they only ran for about a year.

 

As Tom said adapters are the easy option, just depends on how far you want to go.

 

So the three options are -

 

1. As Tom is doing - complete widetrack conversion

2. As I've done - modified VR hubs etc

3. 4 to 5 stud adapters

 

Good luck with whatever you choose.
