I have a 99 Z28 A4 2.73 Gear with the following mods and wondering what stall and str to get. It is daily driven and track driven.

.581 224 112 Comp Cam, Springs, Custom Tune
Mac Mids w true duals
Chromoly LCA's and Panhard, SFC's, Comp Drag Shocks, Strut Brace
Poly Trans and Torque Arm Mounts
Lid and Filter, Ported TB, 85mm ZO6 MAF

Thanks in advance for any input.

 

SS3600 would be good for a daily driver. For max performance the SS4000 would be great but loose. You have decent tires?

TCI 3500 2.5 would work if you want something cheaper.

 

like i always say....go big! if you dont you will regreat it!

 

We have about the same mods... I was told to go with a PT4000 or PT4400 for N/A by Yank.

 

Thanks for input guys.
I've been told to go big because you will always want the next size bigger once you have one.

DEEZ98Z,
Just curious since set-up are close, what you run in 1/4.
My current best is 13.12 @ 109.33 with 2.084 60'(street tires)

 

My best so far has been a 11.98 @ 113 1.69 60'this was with my stock motor. I have since changed motors and alot of other things that I need to tweek... my car should be good for some 11.8's atleast once I work out the bugs. Oh and that is at 3600lbs
