Sub 4s 0-60 M3?

It's not a stat I care about but with practice and better conditions I could have produced some consistent 3.7- 3.9's easily.

On my 335 (tune, meth, LSD) I did it a few times and started in the 4.2 to 4.3 range starting in 2nd gear (6AT) and after lots of practice got consistent 3.8's with a best of 3.5 (also slightly uphill).

All tests with the M3 and 335 were done on factory tires at normal PSI on desolate city streets.

So you're saying the 335 with the right tunes is the same as M3? Why even get M3 then? A 335is owner told me "it's basically an M3 for much cheaper."

If I can save 30k on a 335is and still hit 3.5's I'd be happy with that. Main reason is I hate the simple interior of the M3, doesn't look luxurious at all, cheap bastards.

If 0-60 is all that you are after, then the M3 is not the car for you.

And you won't be able to replicate 0-60 in 3.5 seconds with a 335is. Yes I did it with a 335i, but I had the auto tranny which is not an option in the 335is. You only have the 6speed manual and the DCT. You will never be able to launch those as easily as the 6AT. Maybe 4.0 (with it spinning in 1st) if you get an LSD (which could be as much as $3K) and the correct tune...which is about where a stock M3 is at. And the 335is is priced very close to the M3.

My M3 serves as my track car and airstrip car. 0-60 is irrelevent for both. What is relevant to me is 40-160mph. And how fast I can get around a track. A 335 (whether 335i, 335is or 335xi) is not comparable at all. Even my 335i that had coil overs, wheels/tires, a limited slip diff, Procede and meth injection couldn't compare against a stock M3 at the track. Yes it was quick off the line, and in a straight line, but not at the track.

And the owner who said his 335is is "basically an M3 for much cheaper"...well...

Good luck with your decision.

Sounds like the M3 isnt the car for you then. I suggest you find another car with a faster 0-60 time (seeing as how thats the only important metric for measuring performance) and a nicer interior considering the M3's interior is cheap by your standards.

Damn that probably hurts your neck. Any results on street tires?

The is has a 7 DCT.. what are you talking about?

Those mods must be pretty good to get 335 at 3.5s up hill. Never heard of that kind of performance from a 300hp car.

Read my post closer because that's what I said. The 335is has the option of a 6 speed manual or a DCT. It doesn't have the auto transmission option.

The auto transmission is what allowed my car to do a 3.5 0-60 as I could start in 2nd gear and let the torque converter slip. I wasn't at 300 HP. I was at 412/446 RWHP/TQ with tune/meth AND I had a Wavetrack LSD with Michelin PSS 275 30 19 rears.

The fastest RWD n54's measured on the VBOX were Terry Burger's 135 and Warren's (hotrod182) 335 and both were auto transmissions. Both did something like 3.1 second 0-60 times on street tires.

A DCT trans car just wont do that unless you've got DRs or slicks and then good luck with it holding up. The M3's aren't as hard on the DCT since they make a lot less torque. Mine makes 572 RWHP and only 370 RWTQ. Guys with upgraded turbo 335is cars with the DCT are already seeing problems from too much torque.

Best I've done 4.4 (vbox) and this was w/o launch control; easing the throttle until clutch engaged (to avoid damaging the clutch). Limiting factor: traction/tires. No grip at all with launch control. With better tires I can probably do it (sub 4).

Thanks for the info. My knowledge is well under served on all the mods you can get so I'm trying to research more to figure out what kind of car I really want to upgrade from 328i. My goal is driving pleasure and sexy car.

So for your 0-60 you kept in 2nd the whole time to avoid gear change and since you've got plenty of torque you're good to go. Makes sense. Now I don't understand why you're saying you can't do this with DCT? Couldn't you also set it to 2nd gear and gas it? Or isn't DCT so fast at shifting that 1st to 2nd will help?

It seems like the 335 offers the simplest and most flexibility for ridiculous increases in power with the JB4 and some simple add ons from BMW. I noticed the JB4 is also available for the 335is, seems like that should be better, no?

As others have already said, if all you're after is 0-60 speed, the M3 is not the car for you.

Yes and no. The DCT and 6AT are completely different transmissions with different capabilities and tolerances. If you put slicks and a tune on a 335is and try launching in 2nd gear with the DCT, it will break very soon. It is very fragile compared with the 6AT. You can start in 1st gear all day long, but because your numerically high gearing (in 1st gear) and high torque at low RPMs, launching effectively becomes problematic on the street.

I've driven a 335is and it was exactly the same as any n54 335i on 19" wheels. It looks good but the price is outrageous in my opinion for what you get.

You really want a fast 0-60 in all conditions (rain or shine)? Get an n54 335xi 6AT and tune it and get downpipes an intake and a water/meth system. You will be doing 3.2 to 3.5 second 0-60 times and quarter mile times of high 11's @ 118-120 mph.

Kinda wish M3 could hit 4.0 for the price as I want to buy and know I'm faster than most.

It can be done with a stock DCT M3 on Apex wheels running slicks.

0-60 is really a traction game and crossing your fingers nothing breaks.

Trap Speed is where it's at to find out what is the faster straight line car

Don't get so wrapped up in trivial stats.

Just to see how she ran, based on my P3, last summer I hit 3.71 in my M3 e93 w/ ESS 600. With the added weight of the e93 (450 Lbs +) the car would hook in no problem. I now have the 650 but the weather is too cool so no traction yet. Besides the extra power over the 600 just breaks the wheels lose. Warmer weather approaches and maybe bigger tires (running 275/35/19 now, going to 295/30's).

Motor Trend managed a 4.9s 0-60 in an S2000 and no one else has gotten much closer than mid 5s. It makes you wonder if the equipment glitched (I can't imagine that a car magazine would just mess up reading the numbers by that much?) or if it was just that once in a lifetime run?
