GMG WC-GT Roll Bar = Leg Room? False. Suggestions?
I picked up a 997 GMG World Challenge bar as it offered (quoting from GMG's site) - "Designed to work standard reclining seats or GT3 fixed back seats offering drivers the ability to move the seat all the way back (Not possible with the factory Tequipment Rollbar) " Perhaps "standard" means non-sport adaptive, which could be the issue here? However, I am not sure if the standard seats have a thinner base & backing in comparison.
While I am familiar with the limitations of the tequipment bar, this statement as I interpreted it is false.
The factory seat is unable to move all the way back, in fact, I've lost a good 4-5" of movement, forcing my knees to touch the steering wheel unless i move it as close as possible to myself and in the highest upright position.
I am 6'3" and I do not have a problem fitting in factory sport seats without the bar, in fact, it'm quote comfortable in the car without it. However, after going through the torture of installing it myself, it's really ruined the ride for me as I am not even comfortable in the car and safety is compromised because if my foot is on the clutch (depressed) during a turn, my hands hit my knees, making it difficult to turn.
I also tried a Recaro SPG-XL on Brey Krause sliders and had EVEN LESS ROOM!
My next option is to try a Brey Krause floor mount and see if that makes any difference with a Recaro Seat. If this doesn't fit it, I'll be removing the bar as it's made the ride unsafe and uncomfortable.
Has anyone experience something similar with the GMG WC / WC-GT bars?
Happy Holidays!

I installed the GMG LMS Harness roll bar instead of World Challenge for concern of seat movement. I can tell you the Harness roll bar does allow full seat movement. Obviously not the same roll bar, but may offer you the additional protection you desire. I chronicled by roll bar installation experience several months ago on the forum, it was murder, but great finished product.

I have the RSS 930 bar and its the same thing. The top inset of the bar is only good for thugging it as the lower brace mount stops the seat from sliding to its back limit.
Maybe the Brey Krause top strut mount bar would be best.

Yeah I am going to call up GMG tomorrow and pitch a fit. I'll likely just drive out to their facility and have them install the LMS bar, though I prefer the look of the WCGT, the lack of leg room is a bummer.

Looks like the mounting point on factory seat would still cause the same seat travel limitation. I'll get clarification next week.

It's still a roll bar:

Your statement about seat belt mount is not correct. As noted above, the Harness bar allows COMPLETE movement of stock electric seat, fully rearward. It is bent is such a manner that it does not interfere. As for not helping in rollover, don't agree with that comment. the geometry of the x-brace compared to two front legs is substantial and IMO would offer substantial additional rollover protection if needed above and beyond car's hard top.

as for the seat belt mounts, heres every bar omg makes. it appears (and i could be wrong ) that they all share the same front geometry but differ in front bracing that can be added and /or the mounting point off the rear mounts either shock tower mount or seat belt mount hole.
the angle of each front downtime appears to be the same regardless of the bar. to much angle it will collapse to little angle to won't meet up with the hole

i had a gmg world challenge bar in randys old 996 turbo and it would not allow full seat slide either. i have a a/p racing rear cage with removable front horizontal and diagonal braces and its the same thing. bottom edge of the seat will hit the bar before full rearward movement

I stand corrected upon further inspection. The stock seats lower plastic trim actually touches the lower front bar mount for the last 1/4" of seat travel only - slight rub, but does not inhibit movement. I would highly recommend getting GMG to install as very difficult and does require small amount of trimming contrary to website description. See attached photos.
