If its to be a 3.0rs darren,get some one to tap/beat in the flat part in the front arch wheel profile as per originals,hard to see from pics if its there.Are they bens arches.
Great project,especially the rear tail!
I have found better grip from the 3.0 tail over the ducktail,but lost 2mph over the line at shelsly walsh,thinking of trying the bigger rsr rear tail if you find one on your travels.My theory on the rubber lip tails,is that the rubber deflects flat at high speed,ie over 100mph,which could lose the drag created and get my 2mph back,dont sound alot but critticle for me.
