C5 Twin Disk Clutches
After doing more research after my "Single disk" thread, it seems that it's only a couple hundred more for some of the twin disks. After doing some preliminary searching, I found most of these clutches to be in the $1000-1200 range.
I'm interested to hear feedback on the following clutches and any other clutches that I may have missed (that fall in that price range).
Spec
McLeod
Fidanza
Ram
ACT
RPS
Zoom
There seems to be some speculation that Zoom and Fidanza are the same. Spec seems to be working well... and breaking driveline parts. RPS seems to have a great reputation but is also much more expensive if you include the flywheel.
What does CF think?

I like my RAM Dual Street. IIRC - it's rated to 900RWT. It's rebuildable for about $400 which I just had done. Smooth and clamps hard. I drive my car in DC rush hour traffic and never even think about the clutch.
Just my $.02

We have used McLeod, Exedy, RPS, and Tilton clutches here.
In that price range the McLeod RST twin has been a very nice unit to work with. Drives good, lightweight, and has held behind a 650 rwhp TT Firebird now with out failure.
Exedy makes a good clutch as well, although engagement is a bit quick.
RPS has a number of twin units that we have used in different applications and have held up to 600 rwhp so far without issue.
Tilton of course has been the be all bad boy of the big HP world, supporting well over 1200 wheel HP.

Have u checked the new RPS twin disk with light weight Flywheel or whole setup is light weight, but its a organic material and ron from vengeance was running sale 995, might check that also, but expect heavy clutch pedal though.

I agree. The RPS Organic twin is a VERY nice unit. Give me a call if you need one. I can sell them for 1k shipped.

I didn't think the Vengeance offer included a flywheel. I thought it had an adapter plate in the picture?
The McLeod is $689 shipped. I'm literally waiting with my finger over the trigger for the McLeod. The vendor is getting back to me on availability.

Well... the vendor was out of stock. I know of another one that has them in stock... but while I was waiting... I did more searching and now I'm back on the fence.
It seems the McLeod, Fidanza, Zoom and RPS are the front runners.

To use an analogy... it's sorta like asking... What's the difference between LG Pros and LG Streets? They are both an upgrade over stock. One just makes a little more power. Does a street car need Pros? No way. Is there _some_ benefit? Sure. The aluminum flywheels take less energy to rotate. This makes for faster reving engines, more fuel efficient (measurable? iunno?) and higher dyno numbers due to less drivetrain loss. However, the heavier flywheels retain energy (inertia) better. This is better for launching and shifting.

When I was supercharged I was running the Exedy twin and loved it, it was a stiffer pedal feel but I liked that. It is very streetable and handled whatever i threw at it. I also ran nitrous with it before the supercharger.

Thanks for the description. I have LG Pro's by the way...

get the light weight flywheel...no one can get into your car and say...it has a regular or a light weight fly wheel or not...impossible to tell the difference...zero difference on the shift..bunch of nonsense...
btw every honda, toyota, subaru etc... has an aluminum fly wheel look at they do on a road course or drag strip when set up.....

So for my car that just street driven, and no racing (drag or auto x) would I be better with an Aluminum flywheel ?
