Both cars are fitted with Tresrey front bulkheads, clamping hexes, preload collars, thumbscrews, RF hinge pin blocks, and red shim kits, as well as Cream F/R towers, battery weight and under servo weight. The car on the left has the 8 Racing +8 CF chassis and the car on the right has the 8 Racing standard length CF chassis.

Here's the +8. Spent some time on the scales earlier too-

Stock chassis - 105.8g
Stock length cf chassis - 52.3g
+8 cf chassis and extensions - 56.3g

Race weight for the +8 chassis is 1682g with cream weight under servo and front battery stop, along with Tresrey front bulkhead, RF hinge pin block, Cream F/R towers. Still have to get Ti turnbuckles for it.
