Default Is it normal for Sachs Pressure Plate to have gouges and indentations on outer edge?

Just received Sachs clutch replacement kit with LuK flywheel from ECS tuning, as my clutch is on the way out. Box arrived quite beat up but I see no physical damage to parts. Upon close inspection of the pressure plate I noticed outer edge has gouges and indentations which appear as a factory defect. Is it defective? ECS tuning stock picture on their website appears to show a pressure plate with similar gouges. Pictures below show the biggest one. There are two more smaller ones next to mounting ears.

I would say that looks very defective - any picture I've ever seen is completely circular.

Totally defective. Go to http://murenae.com/cars-porsche-2/ and compare the picture I had when I changed mine.

Wow, thats crazy. Never seen one like that. Sometimes there are little holes or something from when they balance them, but never seen an edge like that on a brand new one.

Agree, looks like an incomplete cast. I would request exchange part.

ECS tuning is shipping a replacement kit. Let's see.

@ yvesvidal, great write up on the website. I will be sure to have it open when I work on my car.

Well, replacement part arrived and it is marginally better. I wonder maybe those indentations are by design, a method by which the inside core gets balanced, similar to how weights get placed on the rim to balance it.

On picture below new part on top.

Really weird. Almost makes you think they're there for clearance of the mating component, but then you look around the rest of the pressure plate where the same clearances would also need to be and it's smooth.

Wonder if they have a way to see if both pressure plates you received were from the same Sachs manufacturing run.

Those indentations look random to me. Bad casting. Really bad quality control with that company.

Immediately return it for refund. And never buy anything from Sachs again

I'm a PDK guy but have driven many manuals in my day. That casting is ****e. Refund, go somewhere else. If you installed it the imbalance would probably trash your bearings over time.

Agreed, but even as someone who's happy with his ECS spacers, this raises questions for me regarding ECS.

I grew up in Retail...my father would never, ever knowingly sell a defective product (clothes, not car stuff)...it's his reputation, too.

So why the hell is @ECS Tuning doing this?

Not a good look.

both my Sachs PP's looked like this and also had balancing marks. I mean its not pretty but it also wont hurt any thing. A mouse killed my first one. A travel style SAC isnt naturally balanced so in the end you are only losing that little bit of surface area on the pp/clutch interface.

When I build the motor one day I will go with a LuK clutch kit but I got a smoking deal on the sachs for $400 for the whole set brand new (PP, disk, TOB) so Im not complaining.

I don't doubt you @rtl5009, but I just don't get it. A disk, to me, should be balanced should have symmetry.

Can't wrap my head around this one.
