Aftermarket Clutch Q's

[tmontague]

I have a question for those that have some experience with aftermarket clutches on their Yaris.

I'll be installing a lightweight flywheel and clutch sometime this summer and I'm trying to get an idea of what I should choose out of 2 options.

Option 1: Competition Clutch Lightweight flywheel sold with their stage 1 clutch. Cost: $499 USD

Option 2: Competition Clutch lightweight flywheel and an Exedy OEM Pro-kit clutch purchased separately. Combined cost: $400

I'd love to purchase the first option as they are matched perfectly and I know a stage 1 clutch can handle power/engage better. That said, I don't have money to burn so cost matters quite a bit. My question is, is a stage 1 clutch going to perform better than an Exedy pro-kit oem clutch, on a NA engine with a bunch of bolt ons, and is it worth an extra $100?

I don't ever plan to go boosted in my Yaris but I do like to drive very spiritedly and plan on doing some auto x this summer. I can't tell if I'm experiencing any clutch slip as I haven't built a boosted engine and truly felt it to know what it feels like. I could tell if I had clutch slip of a worn out clutch but this is not the case (my clutch seems to be in fine condition) although I'm not a fan of the Toyota oem clutch with its chatter and soft feel.

I can't help but feel a slight lag (slippage?) when I drop to 3rd gear and go WOT at 100km/h. I'm curious as to if it's worth the extra cash to go with a stage 1 clutch to improve the engagement during hard driving in a NA 1nz pushing a bit more than stock HP due to the bolt ons. Or is a stage 1 clutch a joke for those who are not boosted?

According to some other forums the Exedy oem pro-kit clutch is a bit of an improvement over the oem clutch but I don't believe it grabs any stronger.

FWIW I don't ever nor do I plan on doing clutch dumps.

I've got a stage 3 clutchmasters with my supercharger, and I wouldn't recommend anything less for a boosted application. The pedal feel was "much stiffer" than stock when I first got it, but I'm used to it now and it feels like stock. If you have any notions of adding power in the future, save yourself the hassle of pulling the trans a second time and go stage 3.

That said, I have no experience with stage 1 or 2. =)

Dont spend the $20 on the swaybar bushings and put it towards your clutch - then the good one is only $80 more. :laugh:

hehehe, already scrapped the bushings after your advice, put it towards a sandwich plate for my oil gauges in a couple months.

Is there still a benefit to be had with a stage 1 clutch over oem in a NA engine? I won't be getting any more power out of my engine as I'm not going boosted and I've pretty much done everything I can to gsqueeze out as much power as possible with bolt ons. Other than a camcon down the road I don't think I can do much else. That said I'm happy with the power/reliability balance with this being my DD and a hopefully weekend autox'er

If you have no problem with the feel of the OEM clutch then leave it alone. If you decide to change the clutch install an aftermarket flywheel one time as you drop the gearbox. I personally didn't like the feel of the OEM clutch and I had plans for boost (blitz s/c currently installed) therefore I change the clutch setup.

I won't ever buy anything from Competition Clutch again. They are a shit company. They do not honor their word nor their parts that fail.

Other than clutch masters check out the ACT TS6-SPSS.
