If I do a twin it'll be the McLeod since theirs allows you to use your flywheel, no reason to throw away my perfrctly good Fidanza. Now if I had a completely stock setup I'd go with the Zoom, I've heard good things about it even though I hate my ZVT

Anybody have any recommendations on a good setup for the mods in my sig? I'm gonna have the shop install the clutch since they'll have the motor and tranny out. I just want something that's good with 600+hp on daily driving with up to 750+hp at the track.

My personal experience with the Ram Twin w/900 series discs has been very good. It's smooth as can be and doesn't chatter at all. I've never beat the crap out of it because my car isn't tuned but if it does as well as it's doing now once I'm making power then I'll be very happy. I've seen others struggle with them though. Racerat being one of them. She had a great experience with the 300 Series twin and beat the hell out of it. Once that clutch died she tried the 900 series twin and had troubles with it that just never went away. As she mentioned above she went with the Zoom twin which I've seen several others in the community give excellent feedback on. The same goes for Fidanza's twin as it's the Zoom twin just painted and boxed under Fidanza's name. We've sold a few spec P-trim twins to some GT500 and S197 guys who love them. They say that the car drives real well without any chatter and it's rated at some crazy hp numbers.

The newest twin to our lineup is the Mcleod which has been getting amazing feedback from everyone. It can be used with any aftermarket flywheel and has been reported to have no chatter. They've got an 800hp and 100hp version. Both are priced very nice.

Whats good is that we have options.

LOL.. Sorry bout the typo. You know what I meant. :bash:

Lates, Jared

:beer:

Jared,

Can you cut the friction plate off the factory flywheel and put a new one on it? That is what I want to do instead of buying a whole new flywheel. I've heard where you could, but I have also heard where you couldn't.

EDIT: Cut it off isn't really a good description. Can you drill out the rivits holding the factory plate and remove it from the flywheel?

Does anyone know what flywheels what kits come with (steel or aluminum):

Fidanza/Zoom - ?
Ram - ?
Spec - ?


The Zoom/Fidanza Twins use Fidanza flywheels. Ram uses their own and Spec uses their own. I've heard but have never confirmed this but supposedly Spec uses Fidanza flywheels as well.

So are all those fly wheels aluminum or steel? I noticed, like on Lethal's website, that there is no choice on the flywheel material and it doesn't denote what metal the flywheel is.

I'm not sure if that can be done or not with the stock flywheel. With that said I highly suggest as Mcleod does the same that you go with an aftermarket flywheel when using their new RST or RXT twin disc clutch. Reason being is that the friction surface on the aftermarket flywheel mates with a larger percentage of the disc on their setup then it would with a stock flywheel. More surface area= better holding power and performance.

On most of the twin disc setups we sell they come with aluminum flywheels. The only twin kit I know of that doesn't come with a flywheel is the Mcleod RST, RXT which gives the customer the choice to run whatever flywheel they like.


Hope that helps. Jared

Does anyone have any feed back on the spec twins. I see that there are a few people that have them, what i am wondering about the most is how it will do as a DD, and is the the floater plate strapped so it doesnt rattle like the ram.

Thanks

Here's some feedback from a customer of ours. Ron has a pretty sick S197 and needed a clutch to hold the power as well as treat him good on the street.


I was a bit worried when ordering this clutch as any clutch with a torque capacity of 1395 is pretty extreme. I expected it to be completely on/off, no room for slip, and fully expected it to not be streetable. But with my power, and the fact that i blew through a GT500 OEM Clutch i figured i needed something, especially something i can use when i eventually switch to the race and race/NOS tunes.

I can not post the price I paid but Jared @ Lethal is the F*cking MAN. That's all I have to say about the price. Jared got it drop shipped straight from spec and it was here ASAP. I can't thank Jared enough for his input and for also talking to a few of his customers for their experiences with this clutch which definately helped to sway my decision to go with it

Its been about 800 miles of mixed city/highway and it is donig great. When it was first installed i was positive it was the wrong clutch. Pedal is stock feeling with no more or less resistance than i had with the GT500 or my old Spec Stage 3+. This clutch is completely slippable. It is NOT on/off like my spec stage 3+ was. During breakin i had a few instances, all stopped going uphill, where i chattered a bit but i havent had it in a while. I would dare to say this clutch is definately more streetable than my stage 3+ Spec was, easier to slip and get started from a dead stop and it grips like a MOFO.

I loved my spec stage 3+ but this is superior in every single way, shape, and fashion. Anyone with a 26 spline input shaft should have this clutch at the top of your list when thinking of swapping or replacing. Now that the breakin is complete and my shifting is back to normal i will be beating on this bitch at my track rental on the 17th.

Thanks for the info, i am stuck between the spec and the ram I would rather go with the spec for ease of installation but if it wont treat me well on the street then i will have to suck it up and get the ram.

Thanks again.

Holding hp and the type of streetability the clutch will give you mainly depends on the material the disk is made of. Before you buy the clutch find out 2 things. The material the disc(s) are made of and the clamping force of the pressure plate. I belive that alot of the twin disks come standard with organic disks. Organic disks are the lowest grade in terms of holding hp. Great for daily driving and ease of engagement but don't hold power. See if you can get any of the above companies to sell you a twin disk in either a kevlar, semi-metallic, or carbon disk. Granted they would be a little more harsh on the street but it'll hold what you want to throw at it. My $.02.

I have the mcleod twin I think its the 800hp version. My car is right at 600rwhp on the juice and have not had any signs of slipping. Clutch is a little hard to push in but it grabs HARD. Little chatter at first but seems to be going away :banana:

I've been running the RAM Dual Disc since Feb and it has it good and bad characteristics:

Good:
Cheaper than the Spec Dual Disc
Pedal effort is less than stock
Rated at 900 HP
Does great as a daily driver with no chirping or chattering during engagement

Bad:
Installation requires modification of the clutch fork and installation of an aftermarket pivot ball (and be prepared to install the tranny multiple times to get the fork engagement angle correct).
When the clutch pedal is pushed down, the floater plate makes a noise similar to rattling marbles

If I had it to do all over again, I believe I would save $$$ a little longer and go with the Spec clutch...

My 02 cents... :beer:
