is it possible / safe to do


for instance a 310 mm vented disc put on a lathe and took down to 300mm diameter ?

You could put them out of balance if you skim the OD of a disc mate, I know it is only 5mm a side but if you look at a brake disc they are machined to balance them and you might take this away if you skim them down.

the answer is "yes you can" but the obvious question is "why would you want to?"

unless you have mega large discs which will still accomodate a full pad on whtever disc area is left?

tbh dojj i prob wont need to ,


it was one of them questions that came into my head ,


was looking at factory discs and some of them were slightly larger than my planned size

but considerably cheaper ,

hence asking

cant you just take a few mm off the inside of the calliper?

should only need a mm or two for that.

True,although it shouldn't be hard to rebalance them,the only problem could be too deep a cut into the vents plus getting a suitable machine to do it,Icoukd have done this for nothing for you a few years back mate!!!

Machining that much off the od should be ok,it's when you try to narrow them the problems occur,I helped produce millions of discs in ford!

I helped make a lot of scrap as well!!!

afpmsl !!!


hopefully i wont have to ,

just depends on cleances

It's commonly done perfectly safely, very very easy to rebalance, assuming the place has the machine ?, and assuming they need it.

production discs are rearly balanced, higher end stuff is, or mahosive discs (bm 7 series for example)

ive done it before mate with no problems, there only cast iron

kinda mate

the fronts aint a prob , as 18s will take em ,

but there rears are 310 mm , was hoping to get them down to 300 ,

but in reality the 310s wouldnt cause an issue ,


plus with me going granny 5 stud hubs there a bolt on item

just need calipers and bracketry making ,

StephenC

Just checked the pcds myself, granny or galaxy hubs seem to be the same. Ive got some big calipers so Im thinking new hubs and brackets and game on. Im a 17" wheel though so it maybe a case of turning them down til they fit.
