Kid, I believe a squeak is common on coilies, but a knocking just doesn't sound right...

As an update I took off the rear wheels today, and discovered the preload on the coils was a little loose, so the springs could be rattled on the collar. Tightened that and ensured it was equal on both sides, but turns out that wasn't the issue.

Also thought it could have been the tension bars for the boot hinge mechanism (not sure what their proper name is), but again that was a negative. It's looking like the pillow balls more and more Only had the shocks a few months!

If the spring preload isn't correct ie not tight enough, it can unload the pillow balls and create knocking over bumps.

That's what I thought, I tightened it by 3mm so they were level on both sides but definitely not cured it. Might give it another few mm tomorrow morning and see if that cures it. If not I'll take it back to Evo R and see if they have any ideas.

If it were both sides, or all 4 corners I could accept it as just standard coilover rattle, but it bugs me that it's just the one.

And for the record, the title of the thread isn't having a go at the quality of the coilovers, I'm very happy with them, it's referring to how something so simple can be so irritating!
