These ones were on my 240Z when I bought it.
I have recently swapped them out to put another set in that I had made as these ones could give me a lower front height. I was planning on grinding off the weld holding the sleeve on and welding it on a little lower, but since I'm going to sell them I thought I would ask first to see if anyone is interested in them as is, or if you'd like to buy them after they've been lowered a little more. Some may even want to section them if installing shorter strut inserts.
As is, the front can still be lowered a lot more than factory ride height. My opinion is that there is just a bit of wasted space on the threaded sleeve which reduces how much you can lower it by.
The springs that come these are 225lb or 4kg and they take factory length strut inserts (not included).
They will come as in pic (ones on the left) but with the blue top hat obviously.
Price will be dependant on if I modify them or not so let me know if you are interested.
cheers
