i need a new set of gears for my camaro i think i have some 2.73 and there killing me. i went to the track the other day and didnt do so well my 60" suck 2.15. i can acually go threw the finish at 6200rpm in second. the trans shifted by itself to second at 5000rpm but the other day i put some lighter weights in the trans govoner and took it out on the road and it shifted at 6600rpm and it was still pulling so i got the set up havent had it to the track yet. the fastest time i pulled of was 13.75 at 104.65mph how much more do you think i can get out of it from the shift point i have made. also i have 26" tall tires do you think i should go for 4.11 or 4.56. this is a race only car. looking to get in the 12's thanks

4.10s with the 26''ers will work if you can pull 6400 thru the traps. Unless your converter is real loose at high rpms.
