I'm gonna be that guy and say a OE clutch. I think for the price, with close to stock power, you're wasting money buying aftermarket.

EXEDY clutch’s are pretty popular with track guys. They have various stages depending on what you are after. I use an exedy dual disc, but for daily driving it might be a little to grabby for some.

What is our spline count? 23?

Any opinions on this kit?

for the price its not that much more than buying all new OEM stuff

Definitely not a waste of money to replace the clutch if you're going to be tracking the car and shifting at high rpm. The MT82 is known for high rpm lockout, with the OEM clutch & shifter to blame.

Correct, the spline count is 23. I ran that clutch, I ended up removing it because it wasn't disengaging completely at low speeds, and I know I'm not the first one it's happened to. Besides that, it held everything I threw at it and never locked me out of gear as long as the car was moving.

I replaced it with an Exedy Twin disc and have been very happy with it, but once it grabs it's not letting go so it takes some getting accustomed to on the street.

Not trying to bash Exedy, as I know they've replaced a few clutches already and the clutch replacements they've sent out have worked perfectly. I've driven several other mustangs (s197 & s550) with the same clutch and it disengaged freely, so it seems like an isolated issue.

Anyone tried this? Pricey but might be worth it?

The ACT organic disc will be much more street-able, and should feel similar to the OE clutch. The exedy is a 6 puck cerametallic, so it's pretty grabby and likes a bit more rpm + quicker engagement than stock, but will take much more abuse than OE or the ACT clutch you linked.

And what is the spline diameter?
There are a few options for the 2017.

I don't daily drive this car, therefore don't have to deal with traffic, would a grabby clutch be so bad? I drive it to the track and rip on it up in the hills.

What about the pressure plates, its presumed right now I killed the pressure plate fingers (overheated them), but won't know for sure till i pull the trans, are these aftermarket pressure plates stronger/more heat resistant

I don't know, but there shouldn't be any differences in spline count or diameter for 15-17 coyotes. Pretty sure it's the same from 11-19 but don't quote me on that.

If you don't have to daily it then go with the Exedy hands down.

Both pressure plates have a greater clamp load than OE, and are more heat resistant. The Exedy has a forged aluminum pressure plate with cooling vanes whereas the ACT is stamped steel, very similar to the OE design.

Some clutch kits are advertised as 23 spline with either 1" or 1 1/16" diameter splines.

Completely agree. There are a lot of higher priority things to spend your money on if you are tracking the car.

The OP doesn't daily drive his car and seems to have thrashed his O.E. clutch - overheating and etc. I think an upgrade based on how he uses the car would be a wise choice.

I blew my OE clutch on a high rpm heel toe downshift at 120mph. Replaced it with an Exedy Mach 500 and their lightened steel flywheel and haven't had a problem since. I have put the clutch through over a 100 20 minute HPDE sessions and drive the car at the limit so the clutch experiences a high amount of stress and heat.

Highly recommend the Exedy setup for close to stockish power level. It takes the abuse just fine, doesn't make much NVH after it wears in, and shifts quite a bit smoother than the factory setup.

Note: Don't forget to upgrade fluid as well. I'm a fan of Castrol SRF.
