which clutch kit?

Was looking at the stage 1 exedy clutch kit for £277 which ive got in my other car and I have had it to slip once about 2 years ago, and with the new car having more power not sure if its the right clutch or not. maybe have to go for exedy paddle? what do you lot think? also car will be running between 300-320bhp

Iv got a act non paddle in mine, holds 370/370 bhp & lb ft fine, and they got higher power rating than most

ive go that one in mine, decent clutch i think dunno about the power rating i was also wanting to know if it would hold the 1 bar loop mod
