I've made 3 adjustments to my seat and my regular daily commute (1+ hrs each way) has become much more comfortable in the un-modified seat. After reading around I did the following:
- raised the seat as high as I could - a fist worth of space between my head and the headliner
- tilted the seat back more upright
- reduced the lumbar support adjustment
- also pulled the steering wheel closer to my body so I wasn't reaching for the top of the wheel.
Although it now feels like I'm a tad close to the wheel compared to what I'm used to I am now much more comfortable both upper and lower body. The only downside is my left arm no longer reaches the armrest on the door even when fully relaxed (I have short T-Rex arms). However left elbow on the window edge and hand-to wheel is much more comfortable.
At this point I actually haven't touched the seat controls since before the drive home Monday afternoon, whereas prior to that I was fiddling with them at least once a day.
With all that said I still intend to install that electric air bladder lumbar support I ordered - I can't cancel it anyways as it's already been shipped. Although I am now much more comfortable than before I feel the OEM lumbar adjustment just isn't in the exact right spot for me and if this kit offers me greater flexibility and customization it can only be a good thing for me.
Having the seat foam modified was not an option for me. I want it adjustable in case my needs change down the road or my wife needs to drive the car so she can make it comfortable for herself.
It took me about 3 months to get comfortable in my car whereas it normally only takes about 1 month for me in a new car.
What I eventually figured out by getting out of the car and kneeling down right next to the seat and then adjusting it and closely watching the seat movement as I made different adjustments was that the seat height adjuster also moves you incrementally closer to the steering wheel as you raise the height. So if you get the fore/aft distance right and then adjust the height after that it changes the fore/aft distance slightly, just enough to throw you off as you think the fore/aft is set right and then as you drive it feels off because the height has changed this distance. I've never seen this before but I think this may be the reason some people find it hard to get comfortable in these seats.
Once you are aware of this behaviour it makes it easier to adjust accordingly. In a roundabout way this is actually a benefit as it allows you to make smaller fore/aft adjustments by using the height adjuster, raise it one or two settings to move closer and lower to move further away without having to use the seat slider adjustment.
