Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Does anyone have hard data with regard to how much lower (if any) the GT3 seats are (with or without B-K rails) versus the electric OEM seats?
I need to sit about 2" lower in the car...will a GT3 seat provide that kind of lowering?
I've never sat in gt3 seats, but here is some input. I'm 6 4" (long torso, relatively short legs), and my head came pretty close to the roof in my 1999 C2 (stock motorized seats). I have the non-motorized sports seats in my turbo, and I would guess I sit about 2 inches lower in them.
Yes, GT3 seats on their OEM rails will provide just about 2" lower. No actual measurements or data, more of my experience. I had power seats on the C4S. Lowered max, the top of my helmet would just touch the alcantara headliner. With the GT3 seats, there is about a 2" clearance. Push came to shove, you could get the BK rails with adjustable placement.
I would not recommend GT3 seats for the DD with multiple in-outs in a day, though.
I'm also in the "long torso" group...with my OEM electric seat full down the top of my head brushes the headliner...without a helmet.
With the seat full down it looks like the back of my seat is not that high off the floor...not an exact measurement but it measures about 4 inches. The seat cushion obviously ramps up at an angle as you move to the front...it measures about 6 inches where my butt actually contacts the seat.
Does anyone have any idea how the GT3 seats match up with these measurements? If the GT3 seats provide a lower sitting position, it must be because their ramp-up angle is smaller than the OEM seat. I find it hard to believe that the GT3 seat is much lower in the back than 4 inches, but maybe it is.
My reference is only to the stock, electric Boxster S seats. I like a fairly upright driving position which is probably different than most. I think the seatback angle is perfect on the GT3 seats, so somewhat apples-to-apples. I picked up about an inch. Maybe a hair more once the seat cushions settle in. If you want more, like 2", you might need to go the BK brackets route.
As I'm trying to resist, I'll admit that I don't have hard data, but the standard mounting of the GT3 seats yields a lower seating position. Remove the velcro attached seat bottoms, and you're even lower. Without the cushions, you have an enhanced feel for what's happening with the car. I'm not sure if you perceive a lower seating position as a positive or a negative, but I'm just stating (what I believe are) the facts.
that's why I got sunroof delete! The dealer thought he had a headcase on the hands when I showed up to check out the cars w/ my helmet before my purchase.
The GT3 seats with stock side mount will seat you pretty much at same height. To lower once at the track with helmet on, remove bottom cushion and you will fell like sitting on the floor and get better feel of car/suspension.
Dock, I didn't read all of the posts, but realize the bottom cushions on the GT3 seats are simply velcroed in. You can remove them and restuff them. I used some memory foam...so you can easily drop the height. It goes great with the 340mm steering wheel.
I also found that the GT3 seat with stock mount was about the same as the standard electric seat. The GT3 actually is a bit more reclined than I normally sat in my stock seats.
So, I bought the Brey-Krause rails and mounted the seat in the lowest mounting holes. That dropped me about an inch, maybe 1 1/4"; it was quite noticable. Now my helmet clears the sunroof and short people have to sit on pillows. But, if you normally sit with the seat back tilted further back than the fixed angle of the GT3 seat, you could lose all of that height.
Could someone with GT3 seats take a measurement for me?
With the seat full aft, measure from the center of the seat vertically to the headliner.
If someone has the GT3 seat with B-K rails, I'd appreciate the same measurement.
Thanks
