How safe are they? As the choice of 98x4 wheels is a little limiting i have been looking at different pcd wheels but i am not convinced of the safety of wobbly bolts, probably because i only have a vague idea of how they work. Does anyone have much experience of them? How would they hold up under punishment, has anyone used them on a track day? (Apart from Mario, i know they weren't officially wobbly bolts as such )

I've had a set of bling wheels on my Sprinty for a few months now; they have wobbly bolts, but I've had no issues so far. I'm not sure that I'd want to track them though.

Having said that, if you want to track your Coupe I wouldn't use an expensive set of alloys anyway. Better to get a decent set of track tyres on a scuffed old set of standard wheels, and put the bling back on afterwards

No plans to track just yet (well, maybe spa), just wondered if anyone trusted them enough to do it.

A friend of mine has used 4x100 race wheels for years and years on his Uno turbo race car. Another guy I know races a 188 Punto improved production with the same wheels too. I think they are sound. They only offset by 1mm and I have not yet seen a reason put forward as to why that will make any significant difference.

As long as you buy quality components then there safe.

They should've called them self levelling as opposed to wobbly as wobbly and wheels isn't a nice thought.

The main complaint is wheel vibration.
Fitting them takes time as they must be torqued in stages to prevent oscillation of the wheel.
Typically folk use air guns and tighten one bolt at a time.this is where the issues start.
A smear of grease on the collars,do each one up with a small ratchet till it nips then torque them in stages with the weight off the wheel.

Follow that and you'll have no problems.

I have used them in the past without issue.
Ideally a direct fit would be preffered but we don't have much choice with this offset and brake package.

Also make sure you have the correct size spigot rings, this will help alignment/fitment.

Been using them for years and never had a single issue. Just remember to get high tensile stell and you should be fine. Over 8.8 is enough.

you know,wobby bolts is something ive never really understood what they are.

Basically on most wheels the bolts are a perfect fit on the collar.
With aftermarket wheels they can be fitted even if the stud pattern is different.
So the holes on the wheel are a fraction out or in to fit various applications.

A wobbly bolt utilises an adjustable collar or accentric collar.
The wobbly part is the washer/collar only to allow fitment.

When you tighten the bolt the collar moves to allow for the different offset.



So the bolt stays as normal but the collar moves to take up a 1mm difference on the collar clamping area.

8.8 strength is ok but I would personally use 10+ if you can as they don't shear as easy.

i have run wobblies for 3/4 years now and no problems at all with them , they are as strong as normal bolts so i don't see why everyone gets funny when it comes to using them . by a good quality bolt and you should have no problems , i payed £2.50 a bolt and check the bolts everytime i take the wheels off just for peace of mine and haven't needed to replace any of them .

Thanks for the info guys, might broaden my search for new wheels

yeah +1

One of the best ways to make using wobbly bolts safe and reduce vibration is to get aluminium spigot rings made rather than use traditional plastic ones

There's a company in Essex that are very good at solving wheel fitment issues I was pointed in there direction from a couple of DUB mates as they like crazy wheels

But they do these aluminium spigots and can also repitch 4x100 wheels and also bore out the centre bores of some wheels as at ones stage I was looking at getting some bmw mini wheels which use a centre bore much narrower I'll try and dig out what company it was.

But yeah as said providing you take the right precautions they are as safe as normal

Here they are TT tools

Worth every penny in my opinion if wobblies are your only option

Good link

Cheers dude

They come highly recommended for their standard of work.

They do all sorts when it comes to wheels, like increasing positive offset by machining off some of the mounting face off the wheel so you can run different spacers like thick two piece ones for adapting 4 to 5 stud

They also re-pitch wheels which is what I had to to remove the need for wobble bolts.
It's simple to re-pitch a 4 x 100 wheel to 4x 98mm it only needs 1mm taken off the inside edge of the bolt hole. You can then use the standard bolts without any issues.

You can drill the hole 2mm larger, offset moving the centre 1mm out. I had a set done like this but also fitted steel incerts to correct the taper. Not all wheels can be done like this.

Yeah thats it, it all depends what wheels you have, how you want them fitted and the design of said wheel?

But at first glance choice for coupe wheels seems pretty poor but once you investigate further theres many ways round it to get others to fit.


I also know Julian at Rarerims the main importer of Rota wheels in the UK a while ago I did put him in touch with Mario about sorting out club discount for us coupe homies lol but at the time his wife was not well unfortunately and I think it never happened in the end but he's a good retailer for 4x100 Rota's and to be honest if any of you lot rang up and said you was with the club he probably would sort you out some discount anyway

But yeah I was looking at getting these Rota SDM 18x8 alloys off him ET45 slightly modding them and some 20mm hubcentric spacers and they should of popped on quite nicely but then some Azevs poppped up for sale so I snapped them up instead but being BBS LM Style wheels I thought they would have looks right at home on the coupe 8)

Interesting link.

I'm currently running ridiculously big spacers on the back of mine and been looking for some wheels that come in options with either -ve or very low ET.

This could help broaden the search!

It's not the bolt hole spacing that limits the wheel choice for the coupe, it's those damned Brembo calipers.
Find a caliper that's 5mm narrower and you'd be laughing.
