Luk vs Valeo 03-04 Cobra clutch?

I've decided on a stock replacement 03-04 Cobra clutch for my 04 GT, N/A car with 330rwhp. Looking around, Rock Auto has the cheapest kits. $110 for the Luk, and $190 for the Valeo. Is one actually better than the other? Is the Valeo worth $80 more?

Ive used both and dont see any difference. I pulled a stock clutch out of a 98 gt and it ended up being a Valeo clutch. When I blew my old clutch up, I went back in with a stock LUK pressure plate and it felt great and held well.


Side note, I saw your comment a little while ago that you got your dyno tune done. How did everything turn out? What did you make? How does it drive? The questions go on and on lol.

Made 330rwhp, 310rwtq. Drove great, except my out of balance driveshaft decided to crack my tailshaft housing when I got on it to make it into traffic on the highway. I found that going to 4.10s dropped the vibration from 90+mph to 70ish mph. A new aluminum driveshaft fixed the issue, but I noticed the crack when I was putting it in.

Hopefully swapping the trans this weekend.

Man, 330 is a pretty good number! Do you have a dyno graph to share? Im real curious to see the torque curve, the compression should keep the torque up.

I wish I would have known you needed that housing. Ive got a 3650 transmission sitting in my shed collecting spiders right now.

Maaaaan, I had a post about where to get a housing a couple few weeks ago. No big deal though. Bought a new used tranny. Came with a Steeda Tri-Ax that I sold for $120. And keeping my cracked trans for parts.

Can't see the graph very well in pics. Not sure if this really shows the hp/torque curve like a normal dyno sheet at all. X axis is time, not RPM

Hola!
New guy here, I have been out of the building loop for a few years and just picked up a 2002 GT project car.
So it's yellow, it has 4 tires (yes 4, I know crazy right!). It starts and pours water out of the bottom of the trans bell housing (although it doesn't need to run to make potty). So I think I might need some plumbers putty or something.


Was looking over post for tips, for some reason this one caught my eye.

Pssst...... don't tell but I just so happen to work in the powertrain department for a clutch manufacture.
