How much horsepower is the TZ/B dual friction rated for? I'm going to be in the market for a clutch very soon, what is the recommended flywheel for something like that aswell? Thanks!

All the information is on my website. With the SS series pressure plate it is good up to 450-500tq on the street, and with the SS-X pressure plate it is good up to 600tq safely.

Recommended flywheel would preferably be stock, ACT streetlite as best options, otherwise any other flywheel will work with the ceramic friction material. The Kevlar material and the Feramic material are the only ones that can have issues with glazing (kevlar) or friction welding (feramic) undefined severe abuse.

All clutches that are using a kevlar friction disk or dual friction disk, I have media blasted to help with quick break-in. If using a full kevlar disk then I recommend media blasting the flywheel friction surface as well using an aluminum oxide blast media to increase surface porosity and improve kevlar material bedding process.

I have a act 2600 with a solid 6 puck I dd. I don't hate but i don't love it. I drove my friends cumming and a few hondas let me tell you those felt as light as the gas pedal on my car. One more thing my driving sucks or it is really harsh if you don't get it just right for normal dd. My wife wont get in the my car, thinks I'm crazy.

I had a few 6-pucks in my car over the years. Never liked them too much as I smoked a few race transmissions in less miles than an oil change.

As well, my wife absolutely hated my ACT 2600PP w/ sprung hub 6-puck. One time of driving it and she was done. Never drove the car since and maybe a handful of times even being passenger after that. And that was probably 8 years ago.


The benefits of the clutch choices I discussed above is the fact that you have nearly stock pedal feel out of the SS-series pressure plate (2200# PP) and slightly springier pedal from the SS-X Series pressure plate (2700# PP), but both are substantially softer than using an ACT 2600# pressure plate because the pivot angles are different.

As well, the friction choices I normally recommend are the following:

TZ-Series = Full face Kevlar sprung hub clutch disk (Kevlar on both sides)
OFE-Series = Full face Organic/Feramic dual friction sprung hub clutch disk (Organic on pressure plate side, full face Feramic on flywheel side)
TZ/FE-Series = Full face Kevlar/Feramic dual friction sprung hub clutch disk (Kevlar on pressure plate side, full face Feramic on flywheel side)
TZ/B-Series = Full face Kevlar/Ceramic dual friction sprung hub clutch disk (Kevlar on pressure plate side, 8 segmented Ceramic pads on flywheel side)
B-Series = Full face sprung hub segmented Ceramic clutch disk (8 segmented Ceramic pads on each side of clutch disk)
DXD-F = 6-Puck Feramic sprung hub clutch disk
DXD-B = 6-Puck Ceramic sprung hub clutch disk


Of those choices, I have them listed from most streetable to least streetable; but all of the full face disks are very very smooth to drive with no decel chatter. The B-Series full face disk is a bit springy but not super harsh for a full face disk.

With any of the TZ-Series, TZ/FE-Series or TZ/B-Series disks I media blast the pressure plates automatically. If the TZ-Series disk is being used, then I still recommend the flywheel friction surface to be media blasted; but if the TZ/FE or TZ/B disks are being used there is no issue as both of these materials don't require a break-in procedure like the TZ-series.

With the OFE-Series, TZ/FE-Series, and DXD-F Series, both clutch disks break in very quickly but you will have to be careful not to overheat the clutch from either excessive stop-and-go traffic type driving or excessive launches as the Feramic material requires more time to dissipate heat since it is a full face friction material. It is especially vulnerable to friction welding the Feramic material to the flywheel when either a super-thin flywheel is being used, a flywheel with a high carbon steel content (ACT streetlite) or a flywheel with a carbon steel insert friction surface (Fidanza or equivilant). These are still fantastic clutches for DD use and racing, but you do have to be careful and simply give more cool down time between passes to prevent overheating and friction welding of the Feramic material.

With the TZ/B-Series, B-Series and DXD-B Series, there are no issues with friction welding of material because Ceramic does not have the same characteristics as the Feramic material. You can still overheat and degrade the friction pads, but it takes ALOT of abuse to have this happen.

For heat range vs. durability of the clutch disk friction materials, I would put the list like this:

Lowest Heat / Durability:
OFE-Series
TZ/FE-Series
DXD-F Series
TZ-Series
TZ/B-Series
B-Series
DXD-B Series
Highest Heat/ Durability:

For longevity under normal street use for daily driving, I would put the list like this:

Highest Longevity:
TZ-Series
TZ/B-Series
TZ/FE-Series
B-Series
DXD-B Series
OFE-Series
DXD-F Series
Lowest Longevity:

Yup, they can be harsh. Sprung 6 pucks have a bad tendency to chatter with engine braking too. My wife is exactly the same... She refuses to drive it and doesn't like riding in it very much either. I have become pretty good at making it drive smoothly, but it doesn't forgive you at all for bad shifting. It'll give you whiplash to remind you to pay attention.

I think I'm going with the SS pressure plate and the TZ disc. It'll be a while before I order, but I'll contact you when I'm ready Tim. Thanks!
