Yes this is the sort of racer I'm trying to build. so far I have ordered. Roll Design +2.5"/+1" front arms with 4:1 front hipers, Elka system 3 damper, Houser +1" anti-vibe stem and PEP PB1's for the front and the Sonic +1"/+1" rear with PEP ZPS ARC with piggy back rezzies and Sonic anti-roll system. I am looking at using 20" front tyres and 18" maxxis (10" rim) on the rear.
I'm worried whether these wheels will actually fit the Sonic arms. It all looks correct on paper, should give me 2" extra length, 4" wider and 4" lower with the smaller tyres and PEP ZPS system. Extra 2" of travel allround for the big jumps.
This means it should be good for rough MX tracks, or at least thats what i'm hoping!
