Looking for suggestions

[DevilsReject97]

I've got a 2011 1SS with a TR6060. The car has 55k on it and is approaching the 5 year mark. It's due for a transmission flush and a brake fluid flush.

Last night the clutch pedal stuck on me for a small bit and I obviously smelled burnt clutch for the ride home (about 2 miles). It sat overnight and I smelled it some more on the ride to work today. I was a little surprised by the smell this morning, but it was at or right below freezing outside this morning.

I've already been preparing to replace the clutch/slave cylinder, so I'm looking for some suggestions for what to buy. The car is roughly stock and I don't really have any serious HP plans with it. Ideally, looking for something to handle roughly 600hp and still be on a budget...

Any additional recommendations are appreciated as well!
