I have a set for my 2004.5 sedan and was wondering if anyone knows anything about them. I have the ones for the 350z.

I'd stay away from them....I thought I had done a lot of "research" and got a set for my ricer civic. Damn things sagged so bad that it was a wast of money. They were supposed to give me a 1.35" drop and I ended up with about a 4" drop in the front and 3" in the rear. I would not want anyone to risk their G or Z. Could have been a fluke but you never know. On a semipositive note, I had no bounce on the car; even with the sag they handled pretty well if I can say that.

It's all about da G.......

 

Wow, I am very surprised to hear that as the company I bought them from highly recommended the Vogtland springs over the Teins they sold. They said they will stand behind the Vogtland but not behind Teins(in short, for my appliciation). I had done alot of research on springs for a friend's Avolon and I really liked what I read and loved the drop(as it is a little more than most springs). I hope I didn't make a bad choice. My big worry is, it that springs I have are supposed to drop the 350z 30mm(a little over a inch) and the factory 350z suspension drops the sedan 1" from what I have read, so does that mean I will see over 2" of drop?????

 

Dropped 3/4 in rear and 1 1/4 in front.
These aren't the easiest to get anymore but I love them. I have them on a 04 coupe 6m. I pulled them off an 03 sedan at the picknpull. This car had the engine swapped with other updates, Noticed colored springs when walking by and did some research to find out what they were.

Dropped vehicle about 3/4 front and back which was perfect for me. The difference from stock is these make the car feel dead in a good way. I feel nothing... no slop, no bounce, not stiff. Takes hard turns and bumps like a trophy truck with no bounce or movement. Maybe not the best analogy but I'm happy with the change.
