One hun is a TON in 60', just saying We do ok at 1.14, but still feel we can find more. Still working on converter getting it happy. We jumpded o a billet A1 7" this year and as with anything else its a learning curve. On the wheelie bars there seems to be about a 50/50 split in our class with sprung and unsprung bars. We have ours sprung but the springs are inboard not at the wheel. We tried unspring and it upset the car to much. As I am sure you have seen we have a very short wheelbase car that tends to hit the cars hard and just worked best for us. Also we have had our shocks back three times to be revlaved. Finally have them happy and working well. This stuff just takes time, money and parts.
