I wouldn't get a full clutch kit unless your current pressure plate is wore out.
Otherwise, you just order a new clutch disc (get the right diameter) for a T5 since it has a ten spline input shaft.
Oh, and have your flywheel resurfaced before you install all that together. It makes the clutch disc last longer after properly broken in.
When the flywheel is broken in, it's really smooth and shiny, but with a new (rough) clutch disc against the super smooth flywheel... It won't ever grip like it should because both disc and flywheel should be broken in together.
