When doing your clutch you might aswell do everything you can because it's a PITA to take the trans out, especially for something little like a slave cylinder. LUK clutches (E0 SVT factory clutch) come with the pressure plate, clutch disc, alignment tool, and slave cylinder. The only other thing you NEED to do is atleast get your flywheel resurfaced. If you can afford the extra $350+ get a lite weight flywheel from SHO Shop or Fidanza.....
