Here is something I have been looking into myself.

I have some Serious Mods in the "Planning-Stage" and this looks GREAT IMHO.

Unless they've REALLY been working on the "grabbiness" of 'em in the last few years, you should be-aware that the "puck"-style clutch discs have a particularly bad reputation as "tranny-smashers".

From the tone of this article (GRAB and GO!!), I can't say it appears to have changed.

Great for racing, terrible for anything else. Hard on transmissions and drivelines. Especially good at finding were all the "flaws" are, and locating your weakest link.......

I would only consider the new dual plate clutches from SPEC if it's a DD.

That's to bad they have a bad rep. I had a 87 GT with a dual friction and didn't have any problems with that. Maybe someone can come up with some more info from centerforce when addressing this issue

I'm not sayin' that THIS particular disc will do that - merely the reputation of these types of disc. The puck-type typically don't have much "give" to them - the friction material is really "sticky", and usually has a very-narrow slip-zone; acts just like a lightswitch.

I will note that this disc DOES have damper-springs (I have seen puck-discs without them), but they are rather large and appear to be quite stiff.

It is probably a very good disc for racing in a Stock or mildy-warmed car. But, if you're having troubles with shifting already (internal to the trans), or have a really high-HP car, this might be only a temporary install.............

I would think "characteristic" might be a better word than reputation. The DFX is known for being more of an on/off style clutch because it is designed that way. I have the Dual Friction in my '01 and love it. The pedal is as easy as the stock clutch and holds great. You can slip it slightly.

Any clutch that grabs quickly and very hard will "shocK" the driveline. This isn't a bad characteristic if that's what you want. Hard launches with an on/off type clutch will expose any weak links. The 3650 is that wink link.

Keep in mind that Double J and and Kaylan1521 made numerous high HP 1/4 mile runs before they had any tranny problems.

CENTERFORCE® DUAL FRICTION Clutch:

I think this one might just be the Better Choice for a "Slightly Modded" Bullitt.

:: CENTERFORCE® DUAL FRICTION
> click image to enlarge
The Centerforce Dual-Friction clutch set is a performance matched pressure plate & disc combination. Centerforce Dual-Friction pressure plates feature their patented centrifugal weight system (where applicable) and specialized machining processes to provide a performance clutch that offers exceptional street characteristics, while offering outstanding holding-capacity and durability. Furthermore, the Centerforce Dual-Friction disc has a full facing on the pressure plate side for drivability and longevity, while a carbon composite puc style (segmented) facing is used on the flywheel side for a positive engagement and increased holding-capacity. Dual Friction is engineered for those who are looking for the ultimate in street/strip holding power and performance without sacrificing pedal effort and driver control. While the Dual Friction has been engineered primarily as a street clutch it can be used in mild competition applications.

I used the CFDF in a Plymouth Laser AWD - good clutch, nice delivery, nice slip-ability (important in an AWD "launch"). Dusted a LOT, and didn't last as long as I'd have hoped, but was fun while it lasted.

Didn't realize they were still making them.

It looks like Centerforce I might be the one I would get as a replacement for my stock clutch.

Unless I suddenly take up racing as a full-time thing for the Bullitt, I'll be sticking with a stock clutch...

I tried an AP Racing clutch in my old Escort Cosworth (back in the day) and while it was fantastic on the track, it was almost unbearable under normal road conditions - the passengers (if there were any) were severely jolted with every gear change...
