re-drilling wheels

I reckon it might be worth having a chat with a local engineering firm. Have you considered adaptors? It'd give you the opportunity to fine tune offsets too.

Personally, I reckon in the long run you might be better of selling the rims on (4x100 Schmidts should sell well) and buying something that bolts straight on.

Firstly, I'm all for re-drilling wheels. You hear scaremongering out there, but that is usually ill informed people who like to point fingers and shout loudly yet have little or no understanding of what they are really doing.

Unless you have centre caps which cover the wheels nuts, plug, weld & redrill is a neater way to do it (alloy plug the original hole, welded & smoothed...then redrilled between where the existing holes used to be) but multi-stud is not unsafe at all. A lot of aftermarket wheel manufacturers make multi-fitment wheels to cater for things like 4x100/4x108. (see photo below of a set that I have)





Getting them done by an engineering firm is always a good move. Unless you have access to the proper machines and are confident with basic engineering/machining then leaving it to the pros is certainly the way forward with something critical like this.

I'm sure there are people who have attempted it with a cordless drill, a dremel and a healthy does of guesswork, but this is not the way to tackle the job and anyone doing it this way is a bit stupid!

Anyway, enough about that! Now to your wheels. I don't reckon they can be re-drilled to 114.3 because the existing 4x100 holes are just sitting in the edge of the shoulder of the recess. Go out another 7.15mm to make them 114.3 and you'll have a hole right across the shoulder which will not only need a massive taper to get the nut/stud to seat....but will also look very odd!

With this in mind I would personally look for another set of wheels. Don't limit yourself just to 4x114.3's - there are probably other styles which would look awesome that you can get in other fitments, then redrilled, but always look at HOW & WHERE the holes are drilled and judge if there is enough room in the wheel design to cater for a wider stud pattern.

When I looked into redrilling my Lupo to 4x108, I found there wasn't sufficient space on the hubs, but 4x114 to 4x100 has a better chance of working out.

Some wheels are also made with cavities between the 4 main stud holes so there isn't much to drill into.

hmm, perhaps the re-drilled hubs idea would actually be better.

I ve found some adapters on american ebay but they're $90 per pair plus post at $50 plus import duties and then theres extra cocking about with longer studs etc.

I'll wait till i find someone breaking an s12 and bag the hubs from that.

Thanks for your input guys. I knew RR would turn up trumps again
