Why these discs are 330mm ?

Why these discs are 330mm ?

I think the owner has mistaken these for a front kit when it looks like the VTTR rear kit! which is 6 pot 330mm.

Proper front kit should be 355mm, unless he's just got muddled up on disc size on his ad.

Price is a bit steep as it's encroaching into AP territory at his asking price.

The discs look 330mm to be honest.
Check the clearance between caliper and wheel.

Edit : the advantage clearly is lighter discs (rotating mass).
It's just a bit odd removing 345mm OEM discs to put 330mm.
