Z4MCJJ · 06-07-2009, 01:06 AM

That would be great, thanks! I'm not planning on doing it myself any time soon, but it's on the list.

who has the best prices on ss headers? The stepped version is outrageously priced on some web sites...

that's a good read! and this is w/o a tune

eunosracr · 10-20-2009, 06:49 PM

Where can you get 4.10's? I read they are no longer available.

I thought they wouldn't work without a tune?
CEL and limp mode would occur?

Look around on forums,
They are always for sale at M3forum,
and contact Turner Motorsport, I hear they have them, and there is the super pricey Dinan option,

I have the 4.10's in my M, While I'll agree it makes a difference I think people hype them up too much

Good info. Thanks!

I had an e46 m3 that I had nearly every bolt on imaginable.

I also had a slew of other mods such as suspension, short shifter, BBS LM's, etc.
The power youre going to get from all those mods is good (and my car was a bit of a freak motor too), but it really isnt going to increase performance to a substantial level that someone who drives well cant make up for, especially on a track.
Far and away the 4.10s were the best mod I had as far as pure performance goes, but loved the sound of the exhaust. I still think my Z4M coupe with supersprint x pipe and powerloop exhaust sound much better though. Very tight, Porsche/Ferrari like tone, and NO RASP! Getting a nice set of coilovers is prob the other mod that will benefit you most.

The article clearly states 24 hp and 11 lb-ft not incl the wheel tire...w/ wheel/tire upgrade it's 37hp and 21 lb ft. And yes that is w/o a tune as stated in the article. I am only restating what was already mentioned in the article....

as for the 4.10 being the most noticeable I'm going to have to agree. I did the poor mans 3.83 by dropping the overall tire diameter size just to see what benefits there would be w/ higher gearing and even this moderate FD increase there was a noticeable amount of more pull

For those wondering I tried a buddies 335i wheel setup w/ 255/35/18, overall diameter was 25" vs 26"

Starscream · 10-24-2009, 10:57 PM

I've been hearing the 4.10 gear supply from BMW is drying up rapidly,

For instance Tischer no longer has them on the site,
Hopefully because of the link I provided in my 4.10 thread lol

But anyone thinking of this mod better hurry up!
After driving a stock M Coupe last week it reminded me just how much pull these gears have!

ga41 · 10-25-2009, 02:13 AM

Starscream, how does it affect daily driving or highway cruising though?

Starscream · 10-25-2009, 11:50 AM

around town there really isn't that much difference,
remember you can always use high gears like 5th and 6th at 30-40 MPH,
Ive even heard of people going up a few MPG by doing the gears,

On the highway 80 MPH is 3.5K dead on, so that went up a little bit,

Of course you can use a higher gear

but how "twitchy" does first gear become? Is it still usable? 90% of my daily driving is in stop-start traffic...

Starscream · 10-25-2009, 12:47 PM

Yes 1st is still totally usable,

You can however launch the car in 2nd with a few thousand revs and it won't bog down and feels great

I read your review and that got me very interested in the 4.10. Is this the same part:
http://www.turnermotorsport.com/html...CT_ID=E46M3-RP

I've also done 2 mods to the car since I started this thread; GruppeM intake and RPI scoop/skidpads. Next on the list are small things, CDV delete, stubby antenna, ZHP knob, and trim swap. I want to do the 4.10, ESS tune, Supersprint powerloop cans, x pipe and headers... but I honestly don't have an extra grand to blow on my car every month so I'm trying to figure out where to start.

Yes same part number,

I am also waiting for the ESS tune myself,
PM Roman and let him know you are interested too, I'm trying to get a group buy list and get the price of the tune down,
I also wanted to try the headers but worried about emissions testing in NJ

With my RPI exhausts i think the lower revs the better for city driving! :P Good to hear that first gear is still usable though. It's a possible future mod.

I'll PM him.

How many hours do you think it'll take to get the 4.10s professionally installed? I don't want take any chances..

Im sure any decent shop can do it in a few hours,
No installation hardware inside the diff is BMW specific, (bearings and shims I'm talking) so any shop specializing in diffs can do it with in stock parts,

Remember to bring, or have the install Castrol SAF-XJ as the oil!
(or SAF-XJ with FM booster)
Don't use/let them use any other oil! and if you buy new gears you will need to perform a 1200 mile break in oil change again,

I just did my change this week with SAF-XJ with FM booster,

and let Roman know your in it with me

Z4MCJJ · 10-25-2009, 03:51 PM

I am considering 4.10 gearing....btw what volume of Castrol SAF-XJ do our diffs take?

tad over 2 liters,
Its sold in 0.5 liter amounts from BMW dealers,
Just bring a empty clean jug and make sure you SEE them pumping the correct fluid in the jug,

you can get away with 2 liters however,
