So today my new spacers came they are .4cm hub centric vauxhall ones. I fitted one to either side. I then put the wheels back on using my lengthened wheel bolts (50mm) and then thought about taking it round the block. As soon as it started to move i could hear a catching noise coming from the front drivers side wheel. I jacked it up to realise there was still contact between the coilover and the inside tyre wall. So, I had some .9cm spacers I had lying round think they were from Halfords, jacked the car up to find my 5mm wheel bolts had all sheared in half more or less. I put the spacers on and the bolts still went in a fair bit but when i've took the car out it doesn't feel right at all when driving, only the drivers side though.

I took a pic of the hub to see if this can shed any light on the whole thing.

Spacers can make a car feel weird anyway. Alters the scrub radius and can take away all return to centre feel on the steering

4cm and 9cm spacers? Guessing your on about mm coz if there cm that's some big ass spacers your using, I use 20mm on my car there proper hubcentric and sit tight over my hub and the wheel sits tight on the spacer as there machined for the cars centerbore, if your using universal halfords ones with massive centerbores and elongated holes for multi car fitment they won't feel right as they don't sit perfectly central on the hub and throw it out of balance, also if your spacers are spacing the wheel off enough that it no longer sits at all on the origional center bore then the only thing centralising the wheel on the hub is the bolts which won't do it correctly so the wheel will will osolate

No I said .4 cm and .9cm lol, yeah I'm thinking I need some .8/9cm hub centric ones as appose to these halfords ones that are a lot larger than the hub. Will changing the wheels with a different offset be better

You've spaces your wheels 90mm? I'm not surprised it feels weird. Couldn't say what's shearing the bolts though

Out the hub. So strange. I tightened them with the impact gun then torque them up extra tight with a torque wrench. When I first tried to pull of the drive the rears were stuck it felt like to I kept my foot on the accelerator then it freed off. Then when it came to undoing the nuts they were mega tight obviously so I used the torque wrench and I'm thinking Maybee I've somehow sheared them if there was any heat generated in the bearing causing them to tighten.

Looks like the ends of the bolts might be hitting something on the face of the hub carrier and snapping.

But more likely that the back of the tyre or the back of the wheel is fouling on the leg or something local to it and the leverage as you try to move the car is snapping the bolts.

Are there any rub marks on the strut or anything nearby and is there any evidence of rubbing on the rear of the wheel or tyre?

Calls people mongo but struggles to fit a set of wheel spacers without shearing bolts and getting wheel wobble.

Are the bolts the same tensile strength as the originals?
