What is the OEM spring heighs and perch IDs?
 

Looking to go custom on some things, and I dont wanna have to take my stuff apart to measure oem spring heights, and perch IDs.

Thanks!

I'll try to get the info soon if nobody else posts it, as I recall the upper and lower perches are not the same ID tho ...

Thanks..much appreciated.

Hi all,
I'm a 2007 MX-5 owner. I'm very interested in the detail dimensions of the stock rx8 springs. The new MX5 are blessed with some floppy soft springs from the factory and the aftermarket spring doesn't offer enough competitive spring choices. Me and my friend are looking into possibility of utilizing rx8 stock or aftermarket springs since MX5 and RX8 share many suspension components.

We will need the ID, free length, and perhaps photos showing the shape of the taper design would be very helpful.

Thanks

i've got stock springs and shocks in a box. i'll try to take some measurements and photos for you guys in the next couple of days.

Thanks. That will be great! Me and my friends are eagerly waiting :) If only simple modifications is needed, it will be a break through for NC community!

feel free to remind me if i don't get it done this weekend. ;)

i took pics of the rear springs and perches. the shock nut on the fronts was apparently zipped on with an air gun because i can't break it with a 3/8" ratchet. ;) mebbe teamrx8 can snap some pics of the fronts with measurements if he has the stock bits handy. otherwise a few more days and i'll have the fronts too.

rear spring free length: 13.5"
rear spring top perch ID: ~3 5/8"
rear spring bottom perch ID: ~2 3/8"

If no one does it by tomorrow, then I'll get the measurments for the fronts. I have them sitting in a box in the garage, I just don't feel like going out there tonight.

Not to bring back a thread from the dead...but did anyone ever figure out the front spring free length and diameter info?

Man, I dropped the ball on that one!

Year and a half and I still haven't gone out to the garage to measure the springs! Man I'm lazy.

Seriously though, I wish I could measure them, but I traded the car in. I'm sure someone knows or has a set thats just sitting around.

No worries....hopefully someone has it. I don't wanna have to take the stupid things off to get the measurements. Sooo.......anyone?
