Yeah, I was looking at it today and I realized to make it an 8" rotor it ould only need to ass 1 inch all around to create a 8" rotor because it extends both sides. And I thik there would be enough room to fit some nice 8's. But the 6's work just fine.

PS I just built my first jump today. I like how it look (haven't riden it yet I wanted it to sorta harden overnight) But I'm not gonna post pics because it doesn't look big YET!
