my opinion is that the 3.73s are a very significant difference. 4.10's should probably be considered a huge difference. absolutely depends on driving styles and future plans.

 

it voids the warrenty on the rear end

and you need 3 heat cycles to break them in (cold to normal op temp, let it cool down completely, do it again)

 

Yeah and I did that by driving to work and back.

 

yeah...i work 10 mins away, i drove home for lunch so 4 heat cycles....gonna try not sliding the car sideways in the rain.....lol

i feel the improvement in acceleration through the first 3 gears.....now time for d/s and X

 

....and headers.
