Safelight used a Pilkington windshield and their standard gasket on my boxster and I actually like it better than the factory gasket... plus, the factory gasket I ordered from Sunset was all bent up by UPS and couldn't be used, so I didn't have much of a choice.
$425 installed. I'm betting the sekurit one is at least 150% of this or more. Let us know what you pay.
BTW, all the closed courses around here are crawling with LEOs
