I was just curious which (if either) is better and or easier to work with? I am considering a new gear ratio for my 2006 S2000 and would like to plan accordingly for the speedometer correction.

Is either one easier to install, more accurate, or just plain better in anyway? Advantages/disadvantages to either/

Thanks.

I have one but would get the other one if I had to do it all over again...

I used the yellow box that came with my gears. I was very nervous about cutting wires but it turned out to take about 10 minutes. I used the wires under the dash. I figured it would have less chance of corroding there. Calibrated it with my wife

YELLOW JACKET WILL NOT WORK WITH 06+ years.

I learned the hard way, get the box.

I agree

I used the yellow box when I put in my gears. Works great!

Thanks everyone, looks like the yellow box!

Any of you AP2 owners care to comment on what the 2004 through 2006 S2000 is like with 4.56 gears? I ran a complete analysis with a $240.00 dollar program called Drag Race Pro V2, which gives very accurate results, and the 4.56 gears definitely gave the best results out of all the possible gear combinations (4.10, 4.33, 4.44, 4.56, 4.77). Surprisingly even slightly better than the 4.77, at least in the AP2.

Just curious what the day-to-day driving is like? Do you miss the top speed? Do you mind the higher rpm while cruising at 75 mph on the free way?

I guess I should post this in a new topic.

Thanks.
