Helper springs like on some of the tein's and so on should fix this as far as I can tell.

I'll be mailing Mania about this soonish but if anyone already has the answer already, it would be fantastic if you could let me know!

You might just have the shocks too stiff and the rear is skipping over undulations. Soften the rears (relative to the fronts) and see if the rear bounce goes away.

As the height adjustment is not on the spring perch, then they should be captive at all times, as the shock stroke shouldn't change when the height does.

Probably should have mentioned that I've exhausted the full height adjustment from the lower perch but the car was sitting a little too high in the rear so I further adjusted it from the spring. Hence looking for helper springs to keep them captive.
So will softening the damper help now?

Depends, why did you raise them?

Understood.

Dobinsons sell helper springs for $65 a pair. Give them a call.

If you have increased preload, then you have increased springrate, so you need to increase damping (rebound if you can) unless the damper wont be powerful enough to control the more powerful spring. Softening is a common misconception.

Just had the Yellowspeed dynamic sport installed on Monday. They are my first set of coilovers and they are excellent! I took it for a drive though Wisemans afterwards

...
I'm currently set on 20 Front and 12 Rear, clicks from soft.

nice. I love the look of a lowered NC

I just thought I'd add my 2c. Having just bought a set of the street ones with the group buy, and installed them this weekend, the recommended settings are way underdamped (NA).

Also, I'm not one for a lowered car (I drive over speed humps at walking pace) so the height adjustment in the bottom mounts is heaps. (32cm from hub center to edge of guard at all wheels)

After the install, I went for a National Park run at the recommended 12clicks front, 8clicks rear. Too bouncy. I then increased it to 16front, 12 rear. Still a bit bouncy, so I've settled at 20 front, 16 rear. This seems to work well for the majority of roads, but on severe dips, the rear still bounces a bit. I'm considering upping the rears to 20 clicks, but I'll wait till they've fully settled.

Incidentally, increasing the damping to a moderate level significantly improves the ride (as others have eluded to) by stopping the rear end from oscillating with the springs as much on severe dips and bumps on our roads.

I'm very happy with the ride though, as now (the shocks are set better) it isn't too harsh, and is quite similar in feel to konis/kings with heavy front and rear sways attached (my dad's car), but you do feel the bumps a little bit more. Balance is very neutral, with a slight tendency to understeer at very low speed corners (partially due to lots of rear camber) and grip is significantly improved over the stock set up (even on poor quality roads with lots of repairs on corners).

Hope this helps anyone considering buying.

Anyone?

Aren't Mania the distributors for Oz?

Yes - but when they dont return emails, Pms or provide you with the correct information about a product they sell, then you wanna go spend you hard earnt money elsewhere. Hence the original question.

Not to mention the exorbitant prices on most other items.

I just saved about $350 by buying r-package lip spoilers from the US instead of mania.

Whinging bastards.
They've always done their best for me.
Sometimes they are really busy, cut them some slack.
If you cut out the middle man, you can always save money. If that's OK with you, then do it, just don't whinge and give their business a bad name.
