Testing it on the ground we have zero rear steer, on the trail it might be different but I doubt it. we spent alot of time dialing in the geometry to avoid that. I can't wait to get it on the trail and flog it, then I'll be able to post the pics that count!
As far as SAS stuff goes, I prolly don't have nothing worth shiping to you. Marlin makes a great weld in kit for that though, let me know if you need any tech advice when you get started also!
