Default Sanity Check... Mixing Clutch Parts...

OK, so I've read nearly every thread out there about mixing clutch disks and pressure plates. Many say don't do it, many say it's fine.

I completely understand not mixing a 3-puck pressure plate with an OEM rep friction disk.

I just bought a trans, (yay RA gears ) and it came with an Exedy OEM pressure plate (pn AA630 info from THIS THREAD) and a nearly new
ACT 300502ACT 300502
disk. It was installed very briefly before the PO replaced it in conjunction with a dog box. The ACT logo paint isn't even worn off the face.

The ACT disk measures out the same as the worn Exedy disk, the PO ran the combo and said it worked fine, both are OEMish parts, and other threads say it ought to work together just fine. (Although I couldn't find any WRX specific ones.)

Have I missed anything? Am I about to do something stupid? Any thoughts?

Theres no difference in the pressure plate between a full ring and a 3puc, its the disk thats different there...

The big difference in PPs is the clamp pressure, otherwise its a rimg of steel...

The big difference comes in the disc.. weather 3 puck, 6 puck, hybrid, or full ring..

I can tell you, without a shadow of a doubt, that the discs are different thicknesses, that's the biggest issue


Not a great idea, but if it worked before..

Biggest things to be concerned about is disc thickness and diameter

Well, update straight from the horses mouth. Or as they're otherwise known, ACT tech support.

I asked them and their tech guy said there's absolutely no problem running their street sprung disc with an OEM pressure plate.

Will update again once I get it installed.

Please let us know why you keep making useless one line posts without any data or evidence to back them up. Have you tried it? Have you any experience in drive train engineering? Do you even have any anecdotal evidence that would contradict the both the PO and the manufacturer, who both say it did and will work fine?

WTF? I wanted to know if it chatters any different with the stock pressure plate vs the ACT.

P.S. I'm 100% positive you have none of the above experience or information you are asking me for. You asked the opinion of people on a forum. I stated my opinion that it was a poor idea. I still would not do it. You say the manufacturer said it would work no problem. Well then if I were you I would take their advice over anyone on the internet. Now all I wanted to know is if you would post up the results on how much it chatters. Don't get your panties in a bunch kid.

I have an EXEDY lightened fly, with an ACT HD clutch kit, and everything works fine... there is more NVH during engine braking, but otherwise I love it.
