1998 (ST215?) Caldina Clutch questions

Postby cat007 » Wed Jun 04, 2008 10:03 am

Hi all,
My partner has a GTT Caldina.
The car's done 150km's and the clutch is shot. I'm guessing its the original. We drive the car to work each day while stuck in northern motorway traffic so cant have on/off clutch however Gabi wants to race it at Meremere (she's caught the bug after taking my Supra down the track on Sunday) so we don't want to go stock.
The car has exhaust and air filter. No real mods

What would people suggest for a usable but decent clutch? I was thinking, full face organic clutch with heavy pressure plate and then getting the clutch plate re-rivited and some of the meat taken off, turning it into about a 6 paddle clutch plate. That way we wont really loose too much driveablity but we'll have less surface area so good grip.

Thoughts?

If you go with a paddle/puck clutch you can use a lighter pressure plate, I won't be able to explain it very well but its something to do with force vs surface area, and same amount of force for less surface area = more friction.

Probably the best option is go for a factory full face clutch plate and a slightly uprated cover, the car isn't heavily modified so no real need for an extreme clutch and puck clutches are quite bitey and a little annoying for use in a street car.

The heavier pressure plate will give you a firmer pedal, but its way more comfortable/nicer to drive on the street, I've had both in my car and if I wasn't taking it off the road to make it a track only car, I'd be really disappointed in my choice of clutch (puck).

In saying that, a 6 puck like you're talking about is probably available off the shelf and might be cheaper/easier to get than having one modified. The guys at tradeparts in wairau park are pretty good at mixing and matching stuff from various cars to find a solution for you so perhaps a chat to them could prove worthwhile.
