My cousin, understandably, cannot let my car be so much faster than his so he will be changing gearing as well. The difference is he would like to stick with 48P gears for some added durability with the target ratio is something in the 4.3 FDR range. I tested 55/33 with some spare gears I had and they did not come close to meshing so I'm thinking something around 60/36 would work. Can anyone give me a 48P recommendation for a 4.3ish FDR that will fit?
