No you don't. They can be mounted flat also the insert are a thing with K2 and they are suppose to be stronger but I'm mounting flat and taking my chances!
I'm getting the new P14s put on mine as we speak (I don't like high DINs). They are SO sick, I'm so glad the shop hooked me up with them!
And Ralf - they retail at about $339 for the 14s, $439 for 18s, they're not cheap.
Haha, yea theyre 169s. And my room is actually clean now. Pics if you would like. But I think that I had just got home from the mountain, and thrown all my crap on the ground, shelves, ect.
yeah, but totally worth it - they are cheaper than the retail on that site too. I know that in shop they're having a 20% off sale this weekend (Friday - Sunday), not sure if they'll be on sale online of not, but 20% off of those is a sick deal.
