Time to replace my clutch and interested to see if there are any personal recommendations. Normally, I would look at an 03/04 clutch or a McLeod. RPM range is a bit higher than stock with peak HP at 7k. 26 spline input.
Clutch recommendation for 500hp N/A motor.

RXT - Light on the pedal, will hold the power and drag launches.

Do the Specs still have a light pedal option? For 500hp I think you'll be fine with a good single disc. How do you use the car?
I don't have personal experience with Spec, but I knew someone with a bad knee that ran one with the light pedal option and he didn't have any issues with it. That car also ended up with a Whipple on it and it held fine.
I'm a fan of the RXT and really like the one I have. It's just that it's $$$ and way overkill for your set up IMO.

if i recall the complaint about the RST was that it wasnt too difficult to glaze it and once you do, it's done for
Interesting. The glazing issue sounds like break in or potentially a user issue however, the organic discs are more prone to glazing than ceramic. No doubt there.
What are thoughts on steel vs AL flywheel? I have AL now, but I believe steel will be more stable, consistent, and possible better for the TQ curve especially if the dual disc being smaller is possible lighter than a single disc PP?
Are these clutches okay with 7500rpm shift point?

Yes - drag launch an RST and it is toast. Stay away. I've also had Aluminum, lightened steel and the reg. Steel flywheel. The Reg. Steel worked best for me.
I have a ram clutch in mine pushing 525 rear wheel torque. It’s the torque more than the hp levels to worry about. So far 5k miles and no issues.
How is the pedal in terms of pressure to accurate the clutch compared to stock?
You could always have your current flywheel resurfaced. Save a few bucks. I'm pretty sure the RXT is the same diameter as the single disc. No real weight savings.
If you have deep pockets you can always look into Mantic.

Just looked up Mantic, looks great but I won't spend that much. The steel flywheel RXT with Ford TO bearing is $1,357 OOD on Summit Racing and the max I would consider. Thinking that's what I'll go with. I like the prospect of a lighter pedal for D2D user comfort even if it is rated well beyond the 5.0's output that is in the engine bay.
It’s about same
Single disc from ProMotion Powertrain has served me well with a regular steel fw. Not as slippable as oem, but nothing like a light switch either. Great balance for a performance street machine. I had to do a few uphill, second gear starts to get the new clutch chatter out of it (per their recommendation), has been no big deal since then. Easier to push than stock also.
really depends on how you are using the car. if you plan on drag racing, clutch dumps or burn outs, then the rst won't hold up, if not tracking then the rst is a great clutch,
let me know if we can help with one
