about £24 a set www.abacotyres.co.uk get there phone number off the site their not shut. also motorworld and places do them, wobbly is just a nick name they are off set bolts the tapered bit can move, perfectly safe

Yeah theyre safe.

They just make up that slight difference between Fiats PCD- 4x98 and the alloys PCD- 4x100. They look the same as any other bolt.

You can get them Here

If you're looking for the mark of a good garage, phone around asking if they've heard of wobbly bolts . I gave my car over to the first place that had heard of them and haven't looked back since.

ETA: it was cheaper for me to get a supply of bolts from said garage than buy them myself from a supplier. I assume you have locking nuts for the wheels so no-one can pinch your new wheels?

Entirely.

Wobbly bolts have a 'floating' collar that seats on the wheel mating face. The collar is around 2-3mm oversized with respect to the shaft, giving it some freeplay.

This freeplay allows the bolt face to seat on the mating face correctly if oversize PCD wheels are put on. The typical oversizing is 2mm. Eg: It allows you to put 100mm PCD wheels on 98mm hubs.

As far as satefy goes, I cant see why theyre unsafe providing the floating collar engages the wheel face OK, and the threads engage correctly and the wheel can be tightened to the right torque.

oh you must have corect center bore or spigot rings, or they will sit off center.

Thanks for the help everyone .
Found this pic on Rochford Tyres , which helps to show how they work .98 - 100 mm is only 2 mm , which means each bolt will be offset by 1mm - not much when the collar is a loose fit on the shaft .
Rochford only seem to want to sell a set when bought with a set of wheels - helpful !!
I'll try Daves suggestion of Abaco.

Possibly a silly question but..... Can locking wheel nuts still be used if you're running 100mm pcd wheels?

yep you just get wobbly locking bolts

Top notch! Any ideas where to get them from?

Just to keep cinq FAQ up to date, you can also get studs and wobbly nuts (dodgy as it may sound) which are ace

you can also get them from HERE

they sell tuner bolts also for cross drilled wheels and wobbly locking bolts.
