Not sure if this is possible but changing my front brakes to big brake kit, was wondering if the Fronts could be used on the Rears or is it waste of time as not much bigger. Thanks.

It won't work, for a start rears have handbrake drum in rear disks. You will also upset the front/rear bias.

I am sure the rear brakes are upto the job as standard, not even worth considering.

If you want to upgrade the rear brakes get a setup that has been designed or is known to work properly with the fronts.

Unless you really track a car hard just leave rears standard, they are more than adequate

Cool fact, the OEM rear discs are bigger than the front :p

I'd agree, I only changed mine because the Front Callipers needed a rebuild and the price difference to get the used F8x Callipers and new OEM F8x Discs weren't that much more than the Calliper refurb costs and they look much better.

I know many say the OEM Brakes are not good enough and I used to think the same, but you put new/rebuilt Callipers on with new Discs, new pads and new Brake Fluid and you wont be disappointed, OEM Brakes are more than good enough for the road use.

Maybe just get the OEM CSL Discs for the fronts and CSL Front Calliper Carriers, cheap and it's factory.

A mixture of brake dust, rubber pickup and dirt!

I’ll be honest, even if you track an E46 M3 very hard, rear calipers (albeit with different pads) are still adequate.
