991.1 Porsche Roof Bars with Thule Ski System? - Page 2 - 911/Carrera GT - PistonHeads UK

Does anyone know please if the OEM porsche roof transport system (the two bars) will take the standard Thule Ski fittings (that slides into the bars)? I already have the Thule ski system and over the years have moved it across to various vehicles / on top of trailers using a variety of Thule bars (usually the aero ones) but this is the first time I have considered taking the Pork skiing and am hoping I only need to buy the roof transport system if the Thule ski racks fit? I imagine the Porsche roof transport system is in fact a Thule item anyway. Do all 991s have the brackets built into the roof channels or was it an option when the car was new and I need to also check into that? Thanks in advance.

The ski rack fits. However, you may need different screws to attach the rack to the bars depending on what screws came with your ski rack. Can buy the screws online though.

The thule rack had some square / rectangular headed bolts which from memory slid along the channel of the bars and then did up from the top with wing nuts

That's right. However, there are different size heads and shapes for the bolts depending on the bars.

Well my dealer advised me on the phone that my car was not showing on OPC system as having the roof fixings .. which apparently have to be specced at factory But I have 4 little rubber strips in roof on the corners that come off and there are metal brackets underneath. so I think I have them??

You do. I had the same issue and I believe dealers think the brackets mean the roof bars themselves, which are eternally out of stock...

Yep - thanks I agree. Physically took it to OPC today and they confirmed I have them. Bars ordered from Germany (on a 7 - 10 day delivery apparently) just in time for my ski trip early December (fingers crossed for both the bars themselves turning up and indeed more snow low down (Corchevel).

Cor am going around in circles on this one. My Porsche bars land tomorrow and I am leaving Thursday night on the boat to France and nobody can clarify which fixings I need - my Thule 726 is actually at my French place so I need to take the right T Track adapter bolts with me before I leave!! Anyone know the size of them? There are multiple options available on the web at a place called roofracks.co.uk I assume it is the size of the head to fit the track on the Porsche bars and then the length of the bolt itself to pick up the Thule Ski system. I'm minded to actually go to the Tunbridge Wells offices of the roofracks.co.uk place where they have multiple options in stock once I have fitted my bars tomorrow but as I don't have my 726 ski system in the country I can't take that with me and they don;t have one in stock as apparently it is discontinued.. FFS!!!

Does this help?

oooooh that looks very helpful - so what we are saying is the width of the track in the porsche roof system is 20mm???

Yep I put a Thule box on my bars and bike racks and canoe racks and ski snowboard racks. All fit with these bars

Have you got the 726 ski / snowboard system? Any chance of measuring the head width of one of the t-track bolts please and also the length of it? Don't suppose you are in Hampshire??

Not in Hamps Bucks I’m back home early afternoon Will look at my attachments for you

legend. I think my older system is a threaded bolt with a plastic wing nut type thing on the top that drops down through my ski rack fittings and then there is a profiled little rectangular 'nut' that picks it up from the bottom which slides along inside the track of the roof bar. the newer systems are a T-Track nut that has a square head that slots along the track of the roof bar and then there is some sort of nut / fixing that goes on the top.

Here’s some photos of my bike rack with the square t bolt, the other side is just a plastic wedge that slides on top of the bar. My ski rack is in Switzerland My roof box has a u shape clamp that just goes under the bar, as does my canoe rack. I think you’ll be fine Take a hacksaw if you need to trim the t bolt down !!!

superstar - thank you. will report back!!

Well success of sorts The Thule ski carrier fits on the Porsche roof bars but leave the bindings of the skis very close to the roof (worst on my powder skis). I have been out for a blast up to 150kph which is the max I would do on autoroute (normally safe not to get nicked) and they didn’t move / flex too much and hit the roof. I’ve stuck a little pad on the roof under the worst culprit just in case. However am forced to carry the skis forward facing with tips into the wind which I have read somewhere is a bad idea. Thoughts welcome !!! T

If your brakes allow (bindings, not car!) split your skis up. Have the shallowest binding stack on the bottom. Also mounting the ski holder closer to the edge gives more room/easier to get on and off. I have a full width version of the holder you have and found it possible to squeeze the Mrs and my quivers on. When carrying ski tips forward, I taped up the ends and put a sock over them to prevent road grime getting on the bases. This was actually the main reason I got a box... I see on the internet its "good for 200kph" but I've not tested!

Great success

Just an update on this - second ski trip of the year just gone and both the roof system and the 911 in snow in general are mega!!!

Good thread! I used to do this with my 997 when it stayed in Europe, some great trips. Bars and ski holder tested to 200kph+ with no issues apart from increased noise and consumption . Mind you, I found the main issue / limitation with snow on the 911 was clearance. Just check every so often you don't have snow blocking your air ducts at the front otherwise risk of overheating. Small tip, if you ever get stuck in snow switch off traction control for a minute to get you going (then switch on again). Great snow this week on the Dolomites (just returned).

200! I have only been brave enough to get to circa 170 for a short while exiting a Peage. I think they are costing me about 3mpg, I'm getting about 27 on a long run with them on, I usually get 30 if i am being gentle in 7th to eeek out the max range. Interestingly the wind noise is less with the skis in the holders than not - I assume as they break the wind up a bit before it hits the flat vertical section of the Thule ski rack. I found this out as last time I put the skis in a mates car on the way back thinking it would make the return journey quieter with just the bars and ski rack on but it turned out to be the opposite!
