My old e92 m3 vs current e46 m3 - corner balance sheet weights

[Billj747]

Stock seats/full interior in both?

What's the muffler weight difference from OEM to Dinan? I know the cats are pretty heavy.

BTW It will be tons faster if you ditch the interior and drop all that dead weight....like 300-500 lbs.

Yes stock seats full interior.

E92 had
Apex wheels 18s w: 275 rs4 tires
KW CS
Dinan muffler which prob doesn't save much weight. And 2nd cat delete
Stoptech trophy front and rear

E46
Stock 19s ZCP
KW CS
No cats, headers and borla exhaust but an added center muffler

So how much fuel should one corner balance with? I've always done it with full tank...corner balance and align.

If its just the rear section, I believe its 30lbs.

Would make more sense to use half tank because it's statistically closer to where it will be all the time.

Rear section is lot heavier than 30lbs. E46?

[Richbot]

As in the Dinan is 20 or 30 lb lighter than stock.

The Trophy brakes are also worth about 15lb total weight loss from stock, my fronts were 5,5lb per corner but the rears only lose about 2lb because of the big caliper and thicker, larger rotor

Car ran great at WSIR...managed a 1:35:5 w/full exhaust, KW CS and NT01. Weather was very hot...looking to car my non aero time of 1:32:8 in the E92 w/ KW CS, Stoptech Trophy (before I added aero) on Rs3 tires which was done in winter weather. E46 hit about 120mph on straight and e92 hit 134mph... ;(

I was talking about the weight savings.

I've heard 1/4 tank, full tank, and don't matter. Now I can add 1/2 tank

Someone told me that I should do it at 1/4 tank because it gets better as you go...not sure I buy that.

But I think you have a good idea...but I'd say corner balance at 5/8 to 3/4 of a tank since you'll be between a 1/4 tank and full.

Yeah that makes sense. You want it to be as close to ideal set up and weight all day. Remember to take the weiners and beer out of the trunk before you go on track also.

[Richbot]

you also want the car to use the tires most efficiently when it's heaviest because a compromised setup with a full fuel load will wear the tires faster than a setup which isn't ideal at lighter fuel. But our cars weigh 3600ish or more with driver and only carry 100lb of fuel, and it's low and centrally located so it affects cross weight very little. Not going to make much difference IMO. Now on a 2000lb racecar yeah then you want to think about when you want to be fastest and set up with the expected fuel load in mind

Great info...makes sense!

You want to corner balance it with the driver weight in it.

Agreed, 1/2 tank is probably the best, but as long as you have the same fuel load each time you corner weight it, it does not really matter.

Thanks billy. Think James was correct 3/4 would be best since never run below 1/4. Get fuel starvation.

Fuel starvation? Ah that's right with the stock gas tank (e46 M3) and why I spent all that money on a fuel cell with dual pick ups, surge tank and BMW motorsports fuel pump. No issues here

Hey but I have an extra 100k for keeping the tank full.

Ok, so here's the million-dollar question: which car feels more fun on the track? Clearly, the E92 is faster/quicker, but which one is more fun?

I went from an E36 M3 to an E46 M3 and I'm now considering an E92 M3. I can't say that the E46 is more fun than the E36. My E36 was supercharged and on coilovers and the E46 is stock, so it's not really a fair comparison, but still... it feels heavy. I can't help but think that the E92 will feel even heavier and kind of take out a big part of the fun factor. For the record, the most fun car I've ever driven was a Lotus Elise 1.8, which had WAY less power than any of these M3s we're talking about.

In stock form...the E9X is WAAAAYYYY more fun. I think a lot of people who complain about the weight and its handling still drive late apexes and straight line brake. You'll notice the weight then.

You drive the E9X M3 with throttle. The E9X throttle steers and corners under throttle way better than the E36/46. The E9X turns, the E46 just pushes. Some people don't like it because they feel like they'll spin.

[J. Dub]

Is there no benefit to this for us daily drivers?

[1MOREMOD]

Not much but a bit.

[roastbeef]

so when an e9x m3 gets corner balanced, do you add ballasts to balance it out or do you remove weight from that specific corner?

[1MOREMOD]

Neither you adjust the coilovers.

[roastbeef]

maybe i had the wrong interpretation of what corner balancing is- i thought it was evenly distributing the weight of the car over the four wheels.

is it actually adjusting coilovers to compensate for uneven weight?
