I don't like the bolt-through ones purely because they're such a pain to line up to put the wheel on. I have those on the racecar because I need 12mm, but that has studs to suit so I can change the wheels easily.

H&R are the only bolt-on spacers I would use because they have steel inserts in the aluminium spacer so you can torque them properly, plus they have TÜV approval. There are some on ebay made by 'Bulldog' which I wouldn't touch with a long pole - they have no centering hub and the wheel bolts in to aluminium which is a recipe for disaster with tyre fitters and rattle guns.

I torque my spacers to 120Nm the same as the wheel bolts and I've never had a problem with them, but then I never let random tyre fitters near the S8 either!

For reference, the hubs in FE wheels are flat, so won't work with the 17mm spacers I mentioned earlier.

I'm bolting my new wheels on now...

20mm with FEs is not going to work in the front. I'd say 10mm is probably max with 255s. 20mm will be fine in the back though, but with 10 on the front you'll have to use bolt-through anyway so you can pick what you want for the rear. 15mm would put the rear wheels about even with the fronts.

Big Red has bolt-through spacers but I can't remember the sizes. Maybe Dean will.

My new wheels are effective ET 43 in the front and 40 in the back so I have more clearance than before which is good since 20mm all round with the balloon Goodyears was a bit tight. Looked good though :D

Great. Thanks +++

There should be a little tool in your boot to help with that :)

Here are the pictures. I have 15mm on the front and 20mm on the rear

Thanks Jim! +++

Problem with "The Little Tool" is that it is only plastic and if big fingers have been there before you the the thread could be damaged.
Mine was.
Last week I managed to clean it up and it was a big help.
All I need now is my strength back, I can't lift the bloodie wheels anymore. :-(:mad:

I had to use a spade as a lever.

It's reasons like that why I have a tame mobile tyre fitter that I trust. He has all the gear to do a job quickly and effectively. Also happy to call by and do small jobs between major callouts.

He's quite a petrolhead (has various track cars) so understands that I, and people like me, cherish our cars. He really likes the S8 with 20's on. +++

If it hasn't snapped because of the weight of the wheel! :ROFL:

I have a pair of steel versions in the workshop, but its still a pain to do, especially if the disc drops off the hub too. Bolt-on spacers hold the disc in place which is immensely helpful when working with the wheels off +++

I think it boils down to who looks after the car and handles the wheels. If you do it yourself there are several advantages to the bolt-on type, but if you have someone else do it there is less to get wrong with bolt-through :)

I have one of them, but he goes on holiday and other rather unhelpful things, AND he does not fit in the boot for problems on the road.
BUT then again my friendly spanner man has similiar problems.
I do know a fuel tanker driver, but he is also very unhelpful character; just like my bank manager, he will not let me have any free samples.
Oh dear, I could go on all day like this.
