Brake disc question...

M0T · 20 Jul 2008 at 22:52

I bought some new spacers for my car and set about fitting them today, only to discover that they didn't have a cut out for the wheel locating peg. This peg sticks out about 15mm and locates into a special recess on the wheel, but is also the bolt that holds the disc to the hub.

Now as far as I can tell this is only to hold the disc in place when the wheel is off as it is very small and is only done up to 10nm, once the wheel is on then the disc is obviously held firmly in place by the wheel and wheel nuts.

Is there any reason that I shouldn't run the car without this locating bolt?

Just there for convenience IIRC, Fiats are the same

Good, I tested them and the nasty vibration I had above 60mph has gone, it was making my steering wheel jump all over the place.

Just found out that the spacers that came on the car had been drilled (badly) to allow the locating bolt to pass through, so they are probably completely out of balance.

out of interest, why do you have spacers on?

Because they are propa blinging yo'.

My car has had some optional Alfa accessories put on it, lowered suspension and the speedline wheels. This means that the wheels rub on the suspension when turning so need spacers.
