I recently changed my rear gear from a 4.11 to a 3.73 and upped the N20 from a 150 shot to a 200 shot. With the 150 shot and the 4.11 gear I went a best of 9.90@134mph with a 1.35 60ft running out of gear on the big end of the track. I recently went to the track again to test the new changes. Now my car is spinning the tires off the line. I ran the car twice last Saturday. My first pass was a 1.43 60ft 9.90@139.8mph with the car spinning off the line.. The second pass was a 1.47 60ft 9.90@138.9mph spinning even worst off the line.. I have full suspension on the car with strange single adjustable shocks in thefront and rear. My rear shocks are set all the way tight right now. Here is a video of the last pass of the night, Please any help would be great..
Thanks
