Add 273's, 340's & 360's to the "318 Race" ?

One question I had as well is with an AX-15 5 speed, if I’m running 2.76 gears my first three gears are nearly identical to the gears of a car with same sized tires, a 904 and 4.10 gears. So should I be honest and deduct .7 from my et to match a 904/4.10 car or take no deductions since technically I have do have 2.76s? :lol:
