You are better to use focus mk1 track rods, if you do manage to source FRP ones, youll pay a fortune for them, but i think the focus ones are only a few mm different. Speak to D170sam, i think he is using focus track rod's and has converted his puma to FRP spec. Just remember if you use FRP hubs, you will need to use FRP suspension, or get hub adapters as the struts are 4mm wider then standard shocks.
