Yeah, There won't be any issues replacing just the rotors.
I've got the Tarox F2000 rear discs on my Bora alongside the Tarox Strada rear pads and they compliment my Tarox 6 pot kit up front perfectly!
The rear discs and pads are in stock at tarox so could be with you within a week, As for the front discs and pads, These would have to be ordered across from Italy, to you by 20th June!
hope this helps chief,
Taa, Al.
