GT3 top mounts with H&R coilovers - 986 Forum - The Community for Porsche Boxster & Cayman Owners

The H&R kits (available in Road and Clubsport variants) are actually rather popular over here as a mid-range option.

Although the picture I attached above is not my pair, you're quite right regarding the missing piece. It's the nut/washer on top (997 343 561 90, item no 2 on the diagram linked above). As my top mounts are spotless I don't believe they have ever been installed on a car. I need to get a hold of a couple of those as well.

Just found a picture of a PSS9 installed with the stock top mount:

I guess that means that at least the MODE part would fit my coilovers since they and the PSS9's seem to have the same inner diameter as stock.

The *nut* part number is: 996.343.561.91

USA retail is 18.42x2

Yes.. I run metric SWIFT springs on everything.. all of our BoxsterSpec race cars run on the PSS9 and I'm not a fan of having to machine/buy the alum bits needed to run a "standard" 2.25in or 2.5in spring.

Buy the mode pieces and be done with it.

Thanks, I appreciate you sharing your knowledge!

I tried to order the perch kit via ******************************************** but it was "no longer available". Other merchant quoted me outrageous ($200+) shipping fees - obviuosly nobody wants my business!

Also, nobody on my side of the pond seem to sell this.

On top of that it seems that the GT3 perches I thought was an option really wasn't since they run 60 mm ID springs. Go figure.

Back to square one, then!
