I want to hear from all Autos in the 12's Natural Aspirated (no Nos)
Mods you have and what you like or wish you did different.

I am trying to make a desision on what Mods will get me in to the 12's

Right Now I have
JLT II CAI, UDP, FRPP 4.10 and MAC Axle-Back
I also use the stock rims with BFG 275/40 17 Drag Radials
my best so far in the 1/4 is
13.31 @ 103.31 1.98 60' ALt 600ft Temp 82 Deg

my best 1/8 was 8.42. My concern is that my 1/4 mile trap speed is so low
and my tranny is shifting into 4th before the trap..
My tune is from Evolution.

I don't have an auto and I'm not in the 12's (we'll see tomorrow night how close i am) but I don't see any suspension mods on your list. I'd at least go with LCA's and relocation brackets so you can change your instant center and get better traction off the start. You'll reduce your 60', 1/8th mi etc....that should get you really close.

Right now traction is not my problem, I am not spinning off the line, my Drag Radials hook well, my 60' ft times are 1.9 not good but not bad.
I am worried about my trap speed being so low. and that my tune is shipting into 4th before the trap.
I race with under a 1/4 tank and remove the trunk contents. I personaly weight 220 this is not helping

4000 stall torque converter. Maybe a tranny brake or line locks.
