Definitely go with a sprung clutch. The unsprung chatter and are much harder on drivetrain parts and not needed for that power level.

thanks.i was thinking sprung but this was after I bought a solid center cause last clutch I had one of the springs fell out an got stuck in between the pressure plate. But if i install the solid centre will it do any damage over time on a daily driver?

solid [unsprung] clutch discs are FOR RACE USE ONLY. This does NOT mean a street car that gets raced occasionally, it means TRACK ONLY cars that only use wrinklewall tires at all times.
Street cars require sprung clutch discs.
Sure, some people use solid discs on the street. sometimes it works, sometimes it doesn't. fact of the matter is, using an unsprung clutch on the street WILL damage your gears, axles, bearings, etc etc.

A spring popping out of the disc is the result of a faulty disc and/or doing high rpm clutch dumps. which are ridiculously stupid and accomplish absolutely nothing.

Also to note, clutches are rated by torque, not HP. And they are rated by crankshaft torque, not torque measured at the wheels on a dyno. Meaning if your car makes 300ft/lbs of tq on a dyno, it's making closer to 350 at the crank, and you will want a clutch rated for 350+tq.

Lastly, don't let anyone tell you that sprung clutches can't hold torque. I daily my car, and abuse it several times every day. Currently making 420tq at the wheels (460-500 tq at the crank). Sprung clutch, zero issues ever. I am not kind to my car.
