i just did the final drive mod on sat and i put on abot 150 miles and let me tell you i am not impressed . by no means do i have alot of mods on my car just the basic bolt ons but this mod i think did the least the car seems to shift smoother and pull a little stronger
but the over all gain in quickness isn't that great and it affects top end on highway although i did walk a honda on the highway:+

your the first i have heard to not like it, anyways to each his own

i wonder if any one who has done this has time slips . i think people who have done this mod are not use to the speedo being off and they see that 6 mph difference and they think it's their actual speed. itdid change the acceleration but not as much as they make it out as
or maybe my car is just that slow? i wonder what my speedos ganna be like when i put my 17's back on

you wanna sell the gears then?

didn't say that is justthat people make the mod out to be alot better then it is . i won't be taking that shit off had some problems with the bottom gear the cup behind it kept coming outta place with the impact

I'm sorry that your butt dyno didn't approve. changing a gear ratio isn't a new idea. old heavy metal have been doing it forever.

Sucks for you. I know I felt a great difference. What mods do you have? Did you get a tranny cooler too?

i don't know what it is maybe my car is just a piece of shit . when i helped my friend chage the gears and put a spooled rear in his cobra that i could really feel when driving . in my car it only chaged a little it does pull better but i geuss i expected more but for 100$
you can't go wrong . as for if i got a trans cooler i thought tat our cars had one and if so why would i need a bigger one i plan on turbo sometime later that would mean even less air flow threw the fmic

my buddy did the final drive mod and put the AFX UDP on his auto and his times dropped from a 17.6 to a 17.3
