Whiteline told me that the front suspension of the micra doesn't have a lot of travel to play with. And once you lower it only 42mm its pushing on the bumpstops quite a bit.
There are probably a million different opinions though depending on what other cars they are comparing to.
My suspension goes down to a maximum of 70mm lowered theoretically. That's lower than I need it to be. When I had it on that setting, I still had the same travel (because it has both adjustable travel/preload and adjustable height offset - I was only changing the height/offset or effective length of the strut). BUT the real problem is how much going that low mucks up your geometry. Terrible bump steer and the lower control arms are pointing upwards. So as you hit a bump, the geometry gets much worse. The rear end isn't a problem because its just a solid axle, so it was reasonably happy sitting on its arse.
So I raised it up approx 20mm from that setting (Which I'm sure still leaves it looking lower than 50mm lowered springs), and the results were awesome. At this height, bump steer went away, the arms are pretty much flat instead of pointing upwards, and everything is happy. It never bottoms out badly, the control is awesome and the ride height looks beautiful.
The secret to this suspension is the huge controlling dampers. They are so thick they look like they're off an F150 pickup truck or something. The control is amazing. Even though I have a limited amount of travel, it seems to handle anything you throw at it, these dampers are crazily good. I couldn't go back. But I still enjoy the whiteline equipped white super s. The whiteline gear is just great. Car sways around more, but on the street its to a very acceptable level and realistically they stay pretty stiff with all the gear installed.
One reason the micra sways even with swaybars is due to the stiffness of the springs. With coilovers and stiffer springs the car hardly sways at all. And I agree that the settings on the konis are a bit annoying. My shocks have about 15 clicks of adjustment, so you can equally and exactly measure out each setting to get it spot on.
I don't reckon the high roof makes all that much of a difference to the car swaying. There's not a lot of weight in the roof really. There's a bit, but I reckon the swaying is mostly due to the springs. It definately is a high/narrow car though.
Yeah Geoff, I thought of that the other day actually. Its a great idea. I don't want to pay for 2 legal documents. So I might postpone the appointment and wait until I have installed the battery. (Or just ensure I install the battery this weekend! hah.) Thanks.
