Dhanj,
Tpms was always an option. If your car has a Tpms reset button by the sunroof controls then it's fitted, if not, no problem. If you do have Tpms fitted, you have to have the sensors all round.
Secondly, they will fit, same bolts, no spacers. Finally tyres are 245/35/ZF20's front and rears are 295/30/ZR20's, do double check this though Dhanj. That's from memory and I'm not home at present so can't go and look at one of the QP's I have in.
