ACT HDSS or Exedy Stage 1 HD?

Gents, I'd like your opinions on these two clutches. The cost is about the same, the ACT being about $50 more than the Exedy.

My intended usage may include a couple trips to the drag strip per year, and maybe a couple of trips to a road course each year, but mostly street driving.

I intend to stay stock turbo and tune it for E85, and might, just might, consider porting the stocker or getting an HTA Green in a year or two, but no big turbo madness. More likely to do cams and other things, like heads, than going with a bigger turbo. I want to keep the spool like stock, and make over 400whp/tq, and use the car for road racing.

So with that in mind, what are your thoughts on these two clutches?

ACT HDSS
Exedy Stage 1 HD

Both would go in with the stock flywheel, I'm not interested in a lightened flywheel.

Single disc = ACT
Twin or Triple = Exedy

On point, I've had my HDSS installed for over 30K on the stock flywheel and love it. Never had the Exedy but just like is stated above I have heard the single disc don't measure up to the ACT singles. Just my 0.02

Good feedback, curious if anyone has more experience on why the Exedy single disc HD is worse?

Leaning heavily towards the HDSS for now, pending a little more info.

Thanks for all the feedback so far gents!

That happens when the pedal is not adjusted properly.

I actually had the xtss for almost 10,000 miles with great results.

Then I moved the a QM twin when I had the big turbo.

Now that I am stock turbomagain, guess what... Xtss again!!!

Excellent unit, and it holds power.... Currently at 408/445 to the tires the clutch is just fine

Can't believe nobody has suggested Clutchmasters. What's your $$$ range?
