I am currently experimenting with a wheel nut/stud conversion for my 106.

With the alloy wheels these studs are fine and do not protrude beyond the alloy. On the steel wheel they are as below. Again they do not extend beyond the rim but opinions welcome.

FWIW I have yet to try them on track, and can easily got back to standard wheel fitment.




It does look a little mad max...

Don't see what they achieve apart from looking cr@p.

Fitting the wheels on a 106 is a complete nightmare. Particularly if your aftermarket brake discs don't have any locating screws.

I thought about a stud conversion but a lot of them apart from the Pug Sport items are apparently of inferior quality. Although it did occur that only one stud per wheel was needed and the standard bolts could be retained for the remaining holes.

I should probably add that this is a race car, so my question relates to passing scrutineering.

Just a thought, with the stud that long aren’t they liable to bend/ snap if contact is made with another car or the scenery.......

Check the blue book. From memory there are several section prohibiting extended studs.

I have checked the blue book. `the sections I think are relevant don't mention wheel studs at all other than not being made of a composite material. I think it is page 286 s 19.7.2. or page 151 s 5.8.1.

With my other wheels on, its not a problem, they don't protrude. So I could present the car at scrutineering with those wheels and it'll not be noticed. But during the day it might rain and I need to use the above rims... nor sure what happens then...

In the 2019 book the first section says "Extended or composite wheel bolts/studs are prohibited".

It's one of the usual horribly written rules in the Blue Book. I think what they're saying is that you can't extend the studs by screwing extensions onto them in which case completely new replacement but longer studs would be ok but it can be interepreted in many other ways. If I had written it I would have put the composite part in brackets unless of course they mean studs made out of Carbon Fibre...

The second one (5.8.2) says "extended studs are prohibited." which is still as clear as mud but again would seem to imply that they mean extending the original studs rather than replacing them. Note there is no mention of the word composite this time.

I've seem multiple cars at every meeting I've been at breaking most of the rules in the 5.8 Wheels section though so I wouldn't have thought it's something you're going to get picked up on anyway. I raced for five years with the centre caps in my wheels before a scrutineer pointed out they shouldn't be on there which is correct.

You'd be extremely foolish to consider racing with stud protrusion anywhere near that.

Whilst it might pass strutinering, the slightest contact with another competitors car will most likely bend a stud(s). Thus resulting in you having a wheel stuck in place and having to cut the stud. Weekend over. Exactly this actually happened to a Peugeot racing in CSCC Tin Tops last season.

Imagine how happy you'd be if you saw this lining up on a fellow competitor's car.

Unless they think their name is Ben Hur or James Bond, they I can see that it's a big safety risk for punctures on other cars, not to mention that sooner or later someones bodywork is going to be ripped open like a sardine can, rather than just a few black swirls to T-Cut off.

It's all a bit Ben Hurr! Its a good upgrade so much easier when changing wheels but thats looks much too far and would cause problems for both in any wheel to wheel contact.

I've used studs on Citroens before and they never protruded that far, but I was never using those steels only alloys.
You could use alloy spacers (hubcentric ones) when the steels are on to reduce the amount these are sticking or else just get some shorter studs.I think I might even still have a spare set from D/T you are welcome to try them (if I can find them).

I think I'll probably try them on track day, and see if they make putting wheels on easier, then maybe change the length of them.

I doubt they would get through scrutineering.

Mine stick out a little (5/6mm) past the end of the nut but I use a few different offset wheels so they have too.
