I think the new "large" wind-restrictor one does the same, but I've not seen one first hand, only the first generation ones that did not. I also don't see this as "available" on their website, so maybe it never made it to market.
I use the OEM, and it satisfies me in looks and functionality. I think I'd give the Wind Restrictor a shot if I didn't have one..
Just installed a windrestricter on my 350 slk. Drove it to Big Bear with top down to test it out. Somewhat dissapointed. Cold air rifles thru the roll hoops hitting the back of my neck. With no air scarf I have to sport a real scarf even when teperatures are in the high 50's. In my Bmw Z3 the plexiglass windblocker extends from roll hoop to roll hoop, solving the problem of cold air draft from the rear. Someone needs to design and sell a roll hoop block even its a rubber condom!
I can get the A1718600174 and the A1718600274. I don't have pictures so I'm not sure what these look like or how they fit. We can get a discount on a group buy. The retail on the '174' is $886.50 for the pair and the '274' is $261.00 for the pair. Based on participation, I think we can get as much as $150 - $200 off the '174' part number.
From that price, I'm guessing the the 274 is the mesh cloth screen. I think that's the one included with the cars, and is strung between the roll bars like a tennis net. I actually use mine (I know, it's ugly, don't start...), and it works really well. I was waiting until I decided which one I wanted to replace it, and as it is so functional, I've stuck with it...
Thanks for the picture. I spoke with our site sponsor Windrestrictor and they don't have this product. I wonder if there is a market for something like a plexiglass piece that go inside the rollbar to block the wind?
