Had my Rotas for 30K miles or so, never had a problem. Not much autocrossing, but the autocross courses been on and seen don't have many potholes either.

Sure, your CL-S wheels probably won't bend as easy, but they are also heavier than my wheels that are larger and wider.

 

Like people are saying: Stay away from the high watt bulbs.

And for the person who asked how you can use 9005 bulbs with 9006 concectors....simply remove the middle piece through shaving it off or melting it with a solder iron.
