Z4M roadster coilover and rear adjustment

Hi all,

I am planning to upgrade my stock suspension for track use. I do about 5~7 trackday events. I would like to know how easy to access the rear shock setting knob. Last time I looked, it looks like the soft-top sits right on the rear shock mount making it pain in the butt to change the shock setting. If you know an easy way, please let me know. Thank you.

hey Chun! Get Rogue Engineering RSMs. They invert the rear shock towers so you can access from the bottom side. Also, get coilovers that have adjustment elsewhere

Most likely I will get the TC Kline DA system that comes with inverted RSM. My main concern is being able to adjust the rear shock without removing the soft-top everytime. I see a lot roadster ppl with coilovers, I would like see if they have any trick to do it without spending hours taking soft-top components out.

I wasn't aware that the TCK D/As came inverted? Or is this only for their newer designs?

I don't recall if mine were inverted. Totally forget lol. I don't tweak mine as you can obviously tell

He lives in the South SF Bay Area up in NorCal. He tracks with me
In the SF Bay Area, we've got a good small group of Z4Ms:
myself (Lon) - titanium silver coupe
runnerx (Chun) - imola red roadster
me & Chun's friend Andy - alpine white coupe
me & Chun's friend Shawn - silver gray coupe
dorifto88 (Mike) - interlagos blue coupe
gferil (Gernard) - silver gray coupe
jd1plt (John) - interlagos blue coupe
iPhoneEngineer (Scott) - silver gray coupe

and others that I can't think of off the top of my head at the moment (perhaps because we haven't met in person, or they're not as active of forum members/buddies ).

Only a handful of us track our cars, but more and more want to join in eventually

Trick is to do like above, except only cut a Slit in the shock cover carpet and remove a bit of the foam so you can get to the knobs.

[ <--- something like this, so that it folds over, when you're adjustment is made the carpet flops back over in place and isn't as unsightly.

Wow that's a lot cheaper than I expected. I hear prices ranging from 400-800 a day. This is good news I look forward to meeting you guys there too!

The carpet on roadsters come that way. There are plastic covers that you gotta remove to expose the shock towers. It's a pain in the ass to remove so it's not something you will want to do every time. I tried to cut a "C" so that it can be folded out of the way but it ended up kinda jagged. I blame the blade

Yeah I say FUCK THAT!!!

It's expensive enough to maintain our cars lol!

NCRC is the absolute best group I've been with. NASA puts on good events too, but they charge a lot so they can hire a bunch of instructors etc.
I'd go with NASA if I were a beginner and wanted to get up to speed as soon as possible.
But for just open track days with no hassle, and good people? NCRC all the way!

Trackmasters is kinda like NCRC, but @ NASA prices

At the bottom of each knob there is a small strut which runs to the side of the knob and is connected with a push pin rivet.
Pull pin out of rivet and remove. This frees the strut.
Now pull straight back on the knob. It is connected to a thin rod which attaches the bottom of the shelf hinge to the plastic piece which sits atop the rear shock mount. The bottom of the hinge is now free.
The top of the hinge clips into the bottom sides of the shelf. Carefully "pop" the hinge out of these clips.
The hinge carrier(plastic piece which sits atop shock mount) has a 10mm bolt at it's front(by front I mean towards the front of car). It is held at rear by a torx bolt(27 or 30?) and a push pin rivet on top.
Once all fasteners have been removed hinge carrier can be removed by pulling in and back and up. It's kind of a pain and needs to be finnaggled up over the shock mount and the other plastic dome that caps it.

I ended up removing both plastic "domes" with a dremel and snips so I am able to access the adjustment knobs on my new shocks from the interior with top up and the shelf reassembled.
Just took my time, lots of light, try not to break anything, and make sure front tab on shelf is in it's slot so it hits the micro switch.
