clutch time..... is RPS worth the extra $$$
So its time for a clutch in my c5Z. I have been reading several threads on this forum and have heard great things on the RPS clutches, the only negative thing I have read about them is on the organic/organic clutch which I will NOT be running.
However I have also heard good things about the SPEC 3+ from people in my power level. (650rwhp-550rwtq)
So my question, is the RPS carbon/organic street twin worth nearly 3 times the cost of the spec?
I'm not someone who has an unlimited budget and $1,500 is a good amount of $$ to me. However I am someone who will spend the money if the more affordable SPEC ($450) is not a viable option.
Thanks!

I doubt that a SPEC 3 + would hould the kind of power you're making.
Remember clutches are rated at the flywheel not Rear Tire Horsepower.
You seem to be at the upper limits of a single disc clutch and should probably look at twin disc.
I have no experience with RPS or SPEC, just the stock and Textralia clutches. I'll be heading down this road later in the year when I do my drive train swap.
I wish you luck.

There are many people on the forum that use the spec 3+ clutches on cars with more power than mine.

HP is irrelevant to a clutches holding power, its all about TQ. The spec 3+ is rated at over 800TQ, as well are some monster clutches. The RPS street twin is also rated at about 800tq. Thats why I ask if the RPS is worth so much more $$ over the spec.

It's all about torque, but I wonder how these other clutches you mention hold up. I have yet to see any long term comparison of how these Monster or SPEC clutches hold-up.
I don't want be changing my clutch every year, etc ... Anybody running one of these clutches ??? Maybe you can post up your mileage and type usage (street, street / strip, etc...)

I have been reading all day on the specs and there are a few guys making more power then me that have been running them for a few years now with many passes on them and still holding. I am starting to lean towards the spec 3+ after the reading I have been doing.

Not trying to hijack.....
I recently converted my TTix C5 Z06 to an RPM A4 and have an Exedy twin disk with honestly less than 1,000 miles on it and 3 passes.
It looks like new.
I don't need it and would like to have it find a nice home....
Don't have a price in mind but i paid $2,200 for it.
It drives like stock. Grandma would love it.
If interested, shoot me a PM. My cell is 425.870.4645
Thank you and please resume normal programming....

I can tell you from experience that the 3+ if properly installed will EASILY and RELIABLY hold over 700ft/lbs with no problems at all and will shift perfectly every time. I highly recommend that you replace the slave/throwout bearing and add a remote bleeder and upgrade to a adjustable master cylinder at the time of install though. And be sure to measure to see if you need to shim it at all. I believe we shimmed about .070" of an inch when we installed the 3+ for a perfect fitment.

I too am looking to upgrade and also have a tight budget. The Monster clutches seem like an almost to good to be true pricing. IIRC, the 800hp/800tq clutch is like $750 or $800? Man, this is so tempting and they look nice and sound like a great engineered piece. However, is there anyone that has drag raced these clutches, is what I would like to know. I am tempted to buy one and find out as my Tex clutch has found it limits, and still works fine as long as we don't get crazy with the torque and spray.
I can vouch for Mark (MMC1) and his clutch, a stand up guy and his word is good.

With the adjustable Master and a well bled slave the pedal feel is great, nice and tight, no slop. You have alot of control with the adjustable master.
This clutch is in my friends car, it had a 3+ in it before hand that was inproperly installed, no shim, stock hydraulics, and the clutch never would fully disengage and only lasted about 500 miles. The new 3+ that we installed correctly with the upgraded parts has been nothing short of phenominal. Has about 5K hard miles on it so far and no sign of it giving up ANY time soon. Its a good clutch IMO.

My Textralia triple holds my power nicely at half the price of a RPS Triple. A Textralia Exoskel twin would hold to 800+ for you. The pedal is stiffer than stock. If you're finished upping the power, the Textralia OZ700 has done well for many at your power level. Even at the track. Although I love my Textralia clutch and have no regrets buying it, I have no doubt the RPS is a more driver friendly clutch. That's what you get for the extra money. If there's any chance you're going to increase power during the life of the clutch, I would recommend a twin regardless of what manufacturer you choose. If you have a billet steel option vs. aluminum, I would choose steel. The inertia makes the car have better manners.
