How much are my gears hurting me? The mods are in the sig below. The car used to be an auto and have since swapped over to a m6. I have not been to the track yet with the setup but when the setup was with an a4 it went 13.40's@106. That was with the stock converter and the mods below. I have not sprayed the car yet but will in the very near future. She currently has 3.23's in her right now and feels strong doesnt really bog at all. Are the gears just going to hurt my 60' and 8th mile and then pick up hella mph after that?. Im not really concerend about the et but more or less what I trap. WHat do you guys think?

I took my car to the track earlier this year with the stock 10bolt with 3.23's and only got 87mph in the 1/8th out of it leaving at 1000rpm... and was a little pissed to say the least (I had to shift to 3rd about 100ft before the 1/8th mile mark, so that probably hurt it)
simply swapping from a 10bolt with 3.23's to a 9" with 4.11's I went from 87mph to 89mph same 1000rpm launch... figure in the extra amount of drivetrain loss I'm getting from the 9" and it easily becomes apparent that gears DEFINATELY are worth the money. 6spd or auto, if I had it to do all over again, that'd been the first thing I'd do to one.
