I have 94 m6 z28 that has cai, 160 stat, madz28 tuning, and cutout. what will give me a greater reduction in et:

1) mac mid-lengths, or
2) a set of 4.10 gears?

im assuming that they are about the same in cost if you factor in installation for the gears (since i can install the headers myself).

when my car only had the cutout, it was running 14.2 @ 99 mph (very crappy 2.4 60 fts -doh)

Gears and TIRES will have more of an impact on your 60' and 1/4 mile times. Headers increase power, which will affect times, but will increase your trap speed more noticably.

IMO, before you start adding more power to your 2.4 60' times, try to get the power you have to the ground (4.10 gears are 'da bomb!).

 

thanks for the advice! i should ditch the 245/50/16 all seasons, and learn how to drive this thing first hehehe.

I will probably do the gears next.

 

Like was said before, gears and some drag radials.

 

As was stated in the other posts, if you just go to 4.11's without getting a set of sticky tires, you won't be able to launch it well unless you are a superb driver.

Headers and gears are a nice compliment. I went 12s on a stock motor with just headers and gears (also with CAI, drag radials, and dual exhaust before someone raises the ). Like was said before, headers will make you faster (more MPH at the big end) and gears will make you quicker (better 60's and ETs if you can hook). But definitely get the drag radials or better before you start modding. It will make things much easier at the track, and you will really be able to see what your mods did for you.

 

Id do the gears and tires first, learn to drive it right, then add LONG TUBE headers.

 

12's is quite an accomplishment with so few mods!!! will the rear end hold up with gears and drag radials?

 

I sure hope so. I bought the gear package from Thunder Racing, which included ARP main studs and the TA rear end girdle with the pre-load studs. I try not to think about the 7.5" or the C-clips when I am racing

 

Mine has held up to numerous 1.7x-1.8x passes without a complaint.

 

Do you think 6-speed cars could hold up just as well?

I'm debating wether I should get gears or save and buy a 12-bolt. Gears are inexpensive, but if I run a sticky tire with them then I'm afraid that they just won't hold up in my M6.
