Problem here is the problem that effects everything these days. Consumers demand cheaper prices, retailers demand cheaper prices to stay competitive, manufacturers use cheaper materials to stay competitive, consumers get sheite products.
I've never understood why everything to do with Mini's is so budget anyway. Im not saying we should be ripped off, but quality should come first.

I thought they were quality, i had had a look at studs at MITP and didnt think any of them were any good, i bought the ones from minispeed after looking at them and they apeared to be better, and i assumed that because they were £1 per stud, not 50p they were made from a better quality material.

I have never seen the minisport ones, or looked for them, but know my dad used to use them back in the day without fail.
so there is no evidence to show that either of these companies studs are from the same manufacture.
And to prove that, i will order some minispares ones tonight when my dads home with the credit card

there must be a reason for that breakage and over doing the torque is the most commen cause, or having spacers fitted that are rubbish this allows the wheel to pull on the stud in the corners.

We have used these studs for more than ten years now without a single problem. We fit them ourselves to customers cars and have not had any issues. This includes the use on high horse power race cars. I think we are dealing with the matter fairly in asking you to let us have a look before we refund you. When we see them we will have a better idea of what the problem is.
You were never told that we would not issue a refund.
Please let's be fair.
Regards,
Mike.

I have had a phone call from minispeed today, they have tested the studs and some from their stock, and will be giving me a full refund.
He did tell me the exact resuslts of the testing but i couldnt hear him properly, but i will find out and let you know properly when i go and collect my money on tuesday.

Hello! I'm new to this forum but I'm an old bloke who used to be a Machine-Load-Control-and-Automation-Systems-Technician at British Leyland Longbridge, the home of the Mini.
Wheel studs should have their heads stamped with the manufacturers trade mark and the tensile strength of the steel. For the classic Mini, the steel properties should be 10.9 which should also be stamped on the head of the stud. These days I don't have a Mini but I still use the rear hubs for trailers.
Avonride suspensions for the classic Mini rear hubs only go as high as 550 kilos per axle. Other makes go as high as 750 kilos. Empirical results show that at above about 600 kilos per axle the wheel nuts on the left hand side tend to work loose. Trying to defeat the unscrewing by over-tightening the wheel nuts will just strip the threads unless the studs and nuts are top class and brand new. I did consider making left handed studs for the left hand side but this is a lot of hassle. Instead Loctite thread-lock will get you home but a better way is to put lock nuts on top of the wheel nuts.
I have never had studs or wheel bearings fail. The failures have always been nut loosening on the left hand side, collapse of rusted hollow-arm suspension units and there has been the odd puncture. Nowadays I prefer solid-arm suspension units but the hollow arm type is OK if the arm is filled with cement or something to keep the weather out of places that cannot be painted.
I would suspect that the dud studs are counterfeits that are made from 8.8 grade steel or lower as they are unmarked. (usually bolts that do not have any markings as to their strength must be considered to be made of 4.4 strength steel (mild steel)) Such bolts are OK for bolting wooden fence panels together but not for holding on car wheels!
This could be a Trading Standards issue as the wheel studs do not appear to be of merchantable quality. There is also the safety aspect as to what might happen if a pothole was hit at 60 mph. Pattern parts that don't work like the originals are a real curse.
Good luck with your litigation!

Pattern parts that don't work like the originals are a real curse. There have even been cases of fake Metric bolts with the heads stamped "8.8" when they were actually made from mild steel. Unfortunately policing against fakes is an uphill struggle as there are so many of them.
