4.10's in a M6 practical?
 

I am thinking of changing the gearing, from stock to 4.10's. This car is my daily driver, so i need to know about the gears. Do you find yourself shifting an assload more, and what are the RPM at 70mph in 6th? How much of a difference do they make, and are thye worth it?

Re: 4.10's in a M6 practical?
 

Absolutley! Probably my best mod to date. Driveabilty is no different. Yeah, you shift a bit more, but its no big deal. You get used to them really quick. At 70mph the rpms are only like 1800 or so.

Re: 4.10's in a M6 practical?
 

Still very drivable on the freeway. You don't actually shift "more", you just shift sooner in 1st-2nd. As the other guy stated, you are only around 1800 rpm at 70 mph.

Great Mod. I loved mine. No difference to me while on the highway.

4.10's in a six speed are way cool... <img border="0" title="" alt="[Cool]" src="gr_images/icons/cool.gif" />

Now 4.56's in a six speed are just Bad Ass! <img border="0" title="" alt="[Razz]" src="gr_tounge.gif" />

Okay,As lame as this sounds,how about gas mileage?
Is there an appreciable differnce in e.t. between 3.73 & 4.10?,OR even a 3.42?The reason I'm asking is I want to do a gear change & have this notion that 4.10's would be overkill.
Seem's that if the motor makes good power that the car's gonna be fast regardless of final drive.I've seen 2.73/A4 equipped cars do quite well.

Re: 4.10's in a M6 practical?
 

I plan on adding 4.10s next and the RPMs are around 2000

Re: 4.10's in a M6 practical?
 

Gas mileage doesn't really suffer much. 4.10s are NOT overkill for an M6. 3.73s are not worth it. I'd say 4.10s (with a good tire) are woth 2-3 tenths over 3.42s.

Can a 4.10 equipped car pull 6th on the highway? In other words,whats the top end with a 6200 RPM rev limit with 4.10's?3.73's

Re: 4.10's in a M6 practical?
 

HAH, ask fireball about his 4.71's.

Re: 4.10's in a M6 practical?
 

Yes that is fine, but put in a 12 bolt, with 4.10 gears you will kill your stock axle. That is not! reccomended.

Re: 4.10's in a M6 practical?
 

with Nittos you should be ok. Just race from a roll and if you do run from a stop just feather the launch and your rear should last with the TA girdle. My buddies rear lasted 2.5 years..

Re: 4.10's in a M6 practical?
 

How will stock axles hold up with the 4:10s after the addition of a T/A girdle & stud kit? This is assuming driving with street tires.

Re: 4.10's in a M6 practical?
 

If you have Nitto's yes but otherwise you won't be able to maximize your traction and take advantage of the lower gear ratio.

Re: 4.10's in a M6 practical?
 

My 4.10's in the stock rear end did not last long at all. About 1 launch at HRP at 4,000rpms on slicks. Here is the real kicker, I broke my brand new Moser 12 bolt with 4.56 gears on the 1st launch at HRP, broke the posi, now I have a spool. No prob. now.

Best of Luck.

Coach that sucks.. HRP must be an awesome track.. Sounds like people hook during launching..
