ZCP seats are comfortable. Not sofa seats but they are comfortable enough to drive for hours straight without aches for me. I’m a thin person though.

I love my ZCP seats but did feel lack of lumbar support within an hour of driving the car. The simple fix was getting that black Samsonite lumbar pillow from Costco and it's all good now.

I will say I like the headrest support on these seats really well too.

Love them! I go on 1hr+ drives regularly and don't have any issues or complaints with competition seats. The lack of lumbar support is not a problem for me since I usually take it away as much as possible when it is there.

I love the look of the seats, and they are comfortable for the most part. Like others have said, lacking the lumbar support is the only drawback, or maybe i'm just getting old!

Competition Package seat adjustment tips?

I just bought a "new to me" 2018 M3 ZCP.

After a few trips over an hour, I'm realizing that something about the way I have these seats set up is bothering my tailbone area and lumbar area. I think the way I had them set up was causing a lot of pressure right on my tailbone with no lumbar support.

I'm curious how you guys have your seats set up to give you the most support.

One thing I did tonight that seems like it might help was to raise the front of the seat as high as it would go relative to the back of the seat (the portion you sit on). This seems to allow my thighs to actually rest on the seat (instead of hover above it) and takes some pressure off my tailbone because it is distributed along my legs and allow my lumbar area of my back to relax. Seems like that might do the trick, but haven't had much ride time with it like that yet.

Already had one back surgery on my lower back so I'm pretty conscious and particular about proper posture and seating these days. Hoping to find a good way to situate these seats that fits me. Any tips on adjustment process are appreciated.

As someone with a serious history of back pain...

1. Tilt bottom so it is as flat (parallel to ground) as possible. That way your hips and knees are more aligned and not your knees higher than your hip.

2. Order a custom small cushion ( 10" by 2") with a zipper and add filling to your liking as a replacement of lack of lumbar support. Put the cushion around L3-4 (hollow of back), not your tailbone like most people erroneously do.

3. Squat at home and see whether your hips are naturally open. If so, make sure you don't sit with your legs too close to each other while driving since that puts more pressure on your back ( refer to Stuart McGill).

Your item #1 is key to what I was playing with today. Given that my spine is a certain length (I'm 6'0"), the rear of the seat (where the base of my spine is) has to be set at a certain height so that my head is at a reasonable spot in the cabin (not too close to the ceiling like that video linked above talks about).

When my ass is in that spot, my knees are bent and above my hips. So that sort of kills that first point about keeping knees flat relative to hips (at least for my body). So my thought was to raise the front of the seat so they support my thighs in that position instead of having a gap there. It feels like I'm sitting back into a wedge, but I do feel more support this way. Not all the pressure is on my tailbone and is distributed along my legs more.

Do you have any recommendations for the lumbar cushion? I will probably also opt for one of these. I have always maxed out my adjustable lumbar in previous cars, so the lack of this type of adjustment on this one is a bit disappointing.

It's tricky since we are all different so you have to try what works for you.

My seating position: seat lowered almost all the way down; bottom at the flattest angle; backrest fairly upright (if it's too reclined, your arms extend and your back arches more - Not good). I'm 6'1"

As for the cushion, I order them in my home country (Colombia) where labor is reasonable. See picture attached. I'm sure a tailor or someone with knowledge of a sewing machine can help you. The zipper is important so you can adjust to your liking. As my back has improved, I've removed some of the filling material. I order several of these and have one in the F80, Mini S, take with me to the movies, etc.

When I first got the car (comp package also), my back was killing me after my morning commute to work (45 min). I also did the same with my seat as you. Brought my butt all the way down and raised my knees as much as possible. This eliminated 2 problems for me. Back feels better and my right knee don’t get sore. The one thing I have to make sure I do, is not to slouch on the seat. Have to make sure my lower back is at the most rear position as posible.

Yes, it does feel a bit like I'm slouching more. Tucking my butt into the wedge of the seat gives me a bit of lumbar support when I do that. Also had to extend the steering wheel out more because this new position I think is tilting me back a bit more as well. Will need to tweak a little more and get some solid time with the seat this way to see how it goes.

That other post @zorrro listed showed someone used this thing for extra lumbar: https://www.amazon.com/Original-McKe.../dp/B000GPS7NG

I have the same company's roll-shaped support for my office chair and really like it, so that might be a better option that a homemade pillow for me since it is something I can buy instead of make.

I bought that thing on amazon and gave up on it after a few weeks. Partly because I found it awkward and partly because I seem to have found a seating position that is mostly pain free.

Good luck, I hope this helps!
@jmg,

Question for you about this comment. I have been playing with the seating positions trying to get comfortable, finding some pain in tailbone area and low back. You specifically mention lowering the front of the seat. I find when I do that, there is a gap between my thighs and the seat and all the pressure is on my tailbone. But if I raise the front of the seat to support my thighs, the pressure is more evenly distributed along my legs and seems to take pressure off my tailbone and let my lower back relax. What is your opinion on the proper way the seat should support your thighs given your PT experience?

Support should be evenly distributed though your thighs. If you find your knees lifted too much from the seat you can either tilt the bottom seat back or move the entire seat back to allow for the straightening of your knee to reach the pedals. Hope this helps! Im not a PT anymore so YMMV

you know what's great for sore stiff back on a drive? (or any other time)

heated seats. even if it's hot out. crank the AC and top the heat out. I do it all the time my back is a mess.

if it's too hot for your ass, get one of the memory foam seat cushions off amazon.

my $.02

I use a small pillow as well for any drive over 15 minutes. I love my my CS seats otherwise, but M5 style seats with massage feature would be nice in the G80

Used that Amazon McKenzie Super Roll today on a 1-hr drive. Having lumbar support totally changed everything for me. These seats are totally comfortable enough if you have lumbar support. However, it's almost too much stuffing, pushing on my back too much. Can probably get used to this more than the seats without any support, but might try to fill this with a different stuffing or find a somewhat softer/smaller lumbar roll to use. I think having something extra there for your lower back is the key for me though.

That thing is too big. It's actually bad for you on firm seats since the vibration will create jerk movements in your back. Plush, small cushion. See my post above.
