Bummer.  Who did you order them from?

The seller said he’s sold hundreds of sets . I asked on FB and heard back from several that they are running them with good results . I wanted to make sure I didn’t get the wrong part . I think they are too small in diameter for the perch’s , but I guess they seat good enough to run. They need to be at least 1/4” bigger . 

Took a photo. They are a bit smaller diameter but work. Most buyers likely never noticed.

Vogtland really did not do a good job of making them the correct OEM diameter.

Yep - kind of disappointing they didn’t get that right . My ST ‘s are a better fit , but they are not progressive. 

Has anyone had experience with the vogtland and eibach springs as a comparison on lowering a 280? Huge bumpers removed therefore riding even higher than stock. Any advice would be greatly appreciated!

Are the Vogtlands even available anymore?  Seems like they faded away.  I Googled around and can't find a place to buy them for a 280Z.

I found a set on eBay that are supposed to fit the 280 series. Another member here just put a set on his car. I assume you would want a progressive spring right?

The Vogtlands are not progressive if that is what you want.

 Eibachs are.

Mainly looking for advice on which direction to go.
