Before a rear end, after Hooker cat-back, Pacesetter Headers, Lid, K&N, SSRA, would it be worth any gains, or should I wait until I can buy a rear end? I know it's not horsepower gains, but how much does it change gear top speeds, and the overall top speed (which really doesn't matter since I never plan on seeing it ) Thanks in advance

umm you will be at around 2000rpms @70mph...it will make your rear-end weaker...but with your mods it doesn't look like you have an overwhelming need for a new rear-end...i doubt you will break it with those mods even ith the 4.10s..and the gains are quite a bit...i could be wrong but i would guess a few tenths in the quarter mile

I see, I heard that it improves gas mileage also, but I know really that depends on the driving I guess. About how much do they run and what brands? I ran a search for 4.10's and wierdly got a bunch of wierd random posts maybe because of 4.10's being in the sig. I think a rear-end for this car is pretty far off (at least a year)... so maybe I should get the gears OR maybe I should just go for other mods.

4.10s wont increase gas mileage...atleast thats what ive been told....i believe if anything itll make it worse?

top end can go to whatever you get it tuned to do....its all in the tune...however i think its better to have a 12 bolt or atleast the T/A girdle for your 10 bolt if your gonna go for a higher gear ratio...so far it seems like no othermods will show you much gain unless you through on a power adder (blower, turbo, spray?)...or mayb heads and cam.....they go pretty far with stock rears...and obviously some tires...i would say nitttos is the safest route...since M6's were known for breaking rears with harder hooking like BFG's or Mickey T's but the T/A girlde will help with that....my buddy BackInBlack has heads and cam with 4.10's in the stock 10 bolt with the T/A girdle....told me no problems jsut would prolly feel safer with a 12 bolt...

hey,i just put in richmond 410 gears a little while back & i love them!!!!!! my car ran a 13.66 before the gears, & after gear install with nittos i ran a 13.01 on really bad 60 foot times!!!

What other mods did ya have??

probably nothing...but those nittos helped a lot too...so that is not all in the gearing...however i would expect similar gains

personally, i wish a rear end with 4.30's and a stage 4 clutch would of been my first mods. those with big and lils will give you more gains than even spray can and still be a perfect daily driver that won't blow up from a lean shot

I expect with Nitto's the gears, and my mods I might could break into 12's.... although I am sure it would take multiple passes.

formula99SD

Which Nitto's are we talking about??

Nm I think its the 555R

i have a slp lid & k-n filter, & that is it except for the new 410 gears & nitto drag radials. i had way to much air in my nittos !!!!!!!!! so yes i know i will get a 12 second slip next time i go to the track if i let some air out,i had them at 35lbs & just found out i should go down to 18lbs at the track so you live & learn!!!! but yes the 410 gears are awesome but they use more gas!!!!!!!! you have a m6 right???? if so DO IT!!!!!!!

I looked in the sponsor area and stuff, and didn't see any 4.10 GP's, so what kinda prices am I looking at?
