Thanks for the reply’s guys, I was told to get the purple mca and they look nice but it might be too long of a build ship time, stance looks like they have them ready to ship everywhere if I didn’t want to go 14/8 or even 14/6. I live in Utah and the fourtune autos dont hold up in our salty weather. My friends springs after 2 years turned to rust

Not sure if that's a fair indictment without understanding the details. I don't see how any other brand mentioned will hold up in salt coated condition for an extended time without proper care.

I'd love to hear more about these. This thread is my first time hearing about MCA and I couldn't find much on them for 370Zs.

They are from Australia, seems to have a strong following. If I recall correctly, I think BGTV8 had a little experience with it before.

I’ve had teins,Bc racing, c-one and Nitron coil overs and the MCA coil overs out perform all of them in my opinion. I rang up MCA and told them what I use the car for and they then worked out what package would best suit me. They also do totally bespoke set ups to suit those with deep pockets. If you are not happy with the spring rates that you receive then they will change them free of charge. Excellent customer service and a genuine pride in their product.

Powered By Max makes a true set as well. Anyone had experience with them?

I use JRZ Rs Pros (1000F/450R)
I was considering at Motion Control Suspension (MCS) and Moton Suspension as well. I would stick with companies that have a presence in your country for any servicing needs would be difficult if you had to deal with international shipping.
