even then its a toss up. On PPBB a guy wrote about how he ordered a Turbo style bumper for his Boxster and got the run around from Brandywine when a Fiberglass part arrived instead of polyurethane one. It may not have been a smooth transaction but at least the buyer has some recourse in dealing with a dealer vs. "some guy".
p.s.
I don't want to sound like a buzzkill, but if you live in an urban area as I do, Litronics are not that big of an improvement over the Halogens. Even on the highways which are always very well lit around here in NY/NJ I don't see a vast improvement.
Rural/Suburban Boxser owners might have a different experience.
In retrospect I would have made this a bottom of the list upgrade, well below performance tires/wheels/radar and my all time favourite thing I have ever spent an aftermarket penny on: Recaro GT3 seats.
