Dimension wise 67-69 and 70-81 Camaro leaf springs are identical. The only difference is the 2nd gen normally uses a little stiffer spring rate. I just called Global west to confirm.

According to Global West, 67-69 and 70-73 use the same spring and 74-81 uses a little stiffer rate.

Hotchkis has one rate for the 67-69 and another rate for 70-81.

Matt, hopefully you get yours done soon. You can be the guinnea pig. LOL.

That's OK with me. If I bust a spring I'm sure I'll let you know!

Seriously, I've heard such good things about them I'm pretty excited.

Let me know how they work. I’m interested in those as well.

Me too. Is your car together what is the ride height for these springs? Got a measurement?

The car us up on jackstands at the moment, but the free arch is the same as Hotchkis...but keep in mind the spring rate is higher. Hotchkis springs vary from 160 to 180 lbs/in.

Thanks Matt. What is the free arch? Please lemme know installed height when you know.

Free arch is 4.5". Stock is usually 6 to 6.5".

BTW, the springs weigh 10.6lbs each.

I've been using the FAF springs for a while now. However, the as-supplied bushings were replaced with spherical bushings.

I also looked at the Hyperco, and liked the spring, but was disappointed at the spring eye. It was stamped steel and split horizontally at the end. The FAF's are a beefy aluminum extrusion.

Overall I like them. On the track there is more lateral deflection. If the car is max turning and hits a really hard bump the inside of the loaded tire will occasionally touch the inner fenderwell.

I too have thought about a locating device, but am hesitant to add complexity. If there was something that was easy to install and try I'd do it. Putting in a delrin bushing and creating a fixed spring end would also help.

There's some info on my website. http://www.geocities.com/casanoc

Carl,
What is your rear ride height with the composite springs? Did ride quality improve?
