Make two piece rotors for a car, offer several different discs for it, and even just replacing the disc part when its worn and manafacturer wise its cheaper! Trust me...im a DJ...!
It's not...
You have twice the machining to do...
Discs (single pc) cost very little to churn out.
Cast them, machine them, heat treat them, hone them...sell them.
You have that twice on 2pc.
If I may be permitted to talk about another brand on YOUR beloved Audi forum, you will find that, for example, Porsche (who were one of the few makers to use 2pc discs - and whose callipers we were discussing in a previous post) charge much less for a complete disc swap on a 996 TT than they did on a 993 TT.
The 993 rotors alone are about the same price as complete 996 discs.
And this from a maker not known to do the customer any favours with their pricing.
PS. bolts are made on such a massive scale that they cost sod all!
Lets say 8 high tensile bolts per rotor/hat.
4 assemplies per car.
32 bolts...as say £1 each plus VAT.
Then the labour...about 1 hour per rotor/hat to strip, clean the corrosion off the faces, emery, re-assemble with new bolts, torque the bolts correctly then put the callipers & wheels back on.
...at £100+ VAT per hour.
Sure...bolts cost nothing.
But fitting these 'free' bolts could cost you £400.
So that's you paid £400 more for no braking advantage. Great.
I'll vote for that waste of money. Not.
