I was looking at all my 12th scales ( 12L4, OD12, and Hyperform H12 v.1) today and examining the chassis and rear pod. What I did noticed was on the 12l4 and the OD12 that the gap between the rear pod and main chassis was different on each side of the t-bar. I took my calipers and measured the OD12 at different points in the gap ( at the three screw holes location on the t-bar). I have found that gap widens from one side to the other significantly by atleast 1.5mm. However on the Hyperform the gap had only widen by .01mm. I have also put all three cars on my setup board to see if I was imagining things, but was not due to the rear pod would not align straight with the lines on the board.The 12l4 has just been recommitioned to race again from its 10 month vacation while during that time I had been running the OD12. The hyperform had seen more action than the 12l4. I was wondering if anybody has seen this with other 12th scales out there from other maufactures even on newer cars?
