Hello Everyone,

I have not found any good threads discussing the best clutch for High Performance Driving Schools and Daily Driving. I have 44k miles on the Evo now with the stock clutch and flywheel and the clutch is fried.

I know it depends on the amount of HP and drag racing. I don't drag race except for the occansional stop light. As far as HP, I will probably just get UTEC and exhaust so nothing crazy there.

What clutch/flywheel should I go with that will give me the longest life for the money? ACT/Clutch Master/Exidy/Cusco/RMR? Single/Dual/Triple Plate? 6-puck/4-puck/Street?

So many choices and they really only talk about HP for the right fit.

What are the advantages for multi-plate/multi-puck combinations?

Would changing from the stock flywheel really make a difference with the few HP mods I plan to do? Would the lightweight flywheel be COMPLETELY annoying on a daily driver?

Thanks for any info,
smanders

You asked specifically about clutch life. With our design we don't do anything to compromise clutch life. The pressure plate's diaphragm spring has a longer working range. We eliminate the stops that are built onto the stock pressure plate. Our friction materials are durable and long lasting. We do not drastically alter the pressure plate's proper geometry. The tradeoff with this method is an moderate increase in pedal effort. I could get even deeper into the subject, but that is a good start.

 

Exedy twin disk works great for me....

 

If your looking for a daily driven clutch and flywheel combo definatly look at the this setup.

ACT - MB7 - HDSS - Heavy duty pressure plate, street disk.

ACT - Streetlite flywheel.

That should be all you need as far as power and torque withstanding without sacrificing your daily driving capabilities.

The Exedy Stage 2 Cerametallic is also another good choice.

I'll quote myself from another thread:

Stock clutch (i.e. single disk) will hold up to about 380 whp on a dynojet (mine did). When I was at Dyno4mance, getting my car tuned, they said that usually the stock clutch would give out around 360ish or so on their Dyno Dynamics dyno (read: ~420whp on a Dynojet).

I now have the heavy duty Exedy Twin Metallic clutch, which, IMO, would be overkill for what you are looking to do. One of the biggest things you should pay attention to is whether or not the pedal effort will be increased with your choice of aftermarket clutch. That is probably where 80% of your driveability will come from (read: too heavy = no fun at all in a traffic jam). The Exedy Twin also has a lighter flywheel, and yes, it can become annoying in traffic.

If you can, see if you can find someone local to you (check the regional forums) with an aftermarket clutch and see if they are willing to let you drive their car.

For track days, I'd be looking for the lightest combination with the best shifting qualities and lightest pedal feel. When you are out on the track, every time you have to slow down your shifting or short-shift, you lose time. When you are talking about a dozen or more shifts per lap and several laps per session, it really adds up.

Of course, you also have to figure in daily drivability for your application (which is very subjective) and overall cost of ownership (which will involve clutch and flywheel life, replacement or rebuild costs, how often you have to pay someone to do the clutch swap if applicable, etc).

Good luck with your decision.

 

Stock clutch hands down! Have you ever been locked out of a shift on the OEM clutch? Has it slipped b/c of your HP level? Has the pedal engagement been difficult.? No I didn't think so. When driven by a skilled driver the stock clutch is unbeatable especially for the price. I have 370 WHP and 23K miles and many trips down the drag strip and it is still holding up. I also participate in HPDE and it has been great. Don't fix it if it aint broke!
