^^^What about the organic Exedy? I hear they are manufacturers of Toyota's clutches. What about RPS? I'm not promoting. I though it would be easier for everyone to see what the Supra Store says about this RPS clutch without giving a link.
"RPS is one of our favorite clutches for import Performance vehicles and a company that is not only an innovator, but a true enthusiast business.
Rob Smith (owner) or RPS has put together some outstanding clutch packages for the 2000+ Celica owner (both 1ZZ and 2ZZ motors). The first of these if the RPS Street Disc Clutch, which we feel is the best Stage I upgrade for Celica owners. If you have the basic bolt-on Performance mods on your car and just need a better overall clutch than the factory unit, then this is your choice. It offers outstanding drivability and holding power.
You will receive the RPS black pressure plate and a fully organic disc with this package. Torque handling capacity is increased to 230 ft.lbs making this a great street clutch. Pedal pressure increase is 15%."
Even with bolt-ons, the stock clutch provides more than enough power.
Going with a clutch that provides 230 ft lbs of clamping power seems to be overkill to me, considering the Celica is not a torque monster by any means.
Just remember, the stronger the clutch, the faster it will wear.
And they aren't cheap to install.
