Hi All

Have just put on my MY02. It has also come with 2 more different coloured spring. Does anyone know which is which. ie tension wise.
And how does this effect the way it dumps. I am running std boost.
The springs in the box are a red and blue. Also it has an extra 3
discs in there. What are these for ?
Cheers in advance (This muppet hasn't a clue)

If I remember correctly, the red is the harder of those two springs. What colour is the one in it?
The discs are spacer shims for putting beneath the spring to give a little more adjustment on the operating pressure. For example on my car the blue is too soft for my liking and the red is too hard, therefor I use the blue spring with 2 shims.

If you need any more advice contact Forge directly they are very informative.

I reckon u have either a Green or Yellow Spring in there at the mo.
