Any one know the C spanner size for the standard ProTech shocks on the MNR Vortx? 1.9" or 2.25"?

Can't you just measure the spring diameter?

I can't answer your question but I just have a "flappy" one that hinges, does both 1.9 & 2.25 with ease.

Thanks both,

Couldn't measure it as I'm in London and the car is in York, but got through to Chris at MNR who confirmed it is 1.9"

Thanks again!

Watch out. 1.9" is the spring ID not the C spanner size. You'll need a C spanner o suit a spring seat with an OD of 62.5mm.
