Recently, my wife Lea and I just acquired a 2001 BMW E46 M3.  This has been forever Lea’s dream car and I have always been a fond BMW fan. 

Back around 1999-2000 before I had FD’s, I owned an ’88 E30 M3 that I loved, truly a BMW motorsport classic. So we decided to give up our trusty S14 240sx that we had for over 6 years and move on to something a bit more mature and classy.

Soon after we got the M3, I find out that there was going to be a local Hot Import Night Drift Demo in Pleasanton, CA the week after the Sonoma Formula D event. I was initially going to use my FD to demo with, but my car needed to go back down to Gardena, CA to Garage Boso to get race prepped and retuned for more power for the final Irwindale round next month.  So I decided to drift our new M3 that we just got at the demo.

To prepare for the event, I hit up KW Suspension for their Clubsport coilovers that features separately adjustable compression and rebound external reservoir shocks and front camber plates. Got some Falken RT-615 tires to burn up and added a set of H&R spacers all around to get that “Hella Flush” wheel fitment. I then had the car aligned at Mach III in San Francisco and put some graphics on to promote some of my sponsors from Graphtech Graphics in Daly City, CA.



When I got to the venue at HIN, there was a film crew from Speed Channel making a show on Hot Import Nights that was waiting to interview me and to get some drift footage. They asked me to explain about some drifting techniques and the car itself. I told them that I never drifted an E46 M3 before so I had no idea how it would drift, so we’ll see how it goes. I wasn’t even sure if the suspension was even setup properly. But I figured it should be fine, so I just went for it.



To my surprise, the M3 drifted awesome! The car was very predictable and stable. A little bit heavy in full stock street trim, but was still able to transition smoothly and could carry some pretty decent angle with aggressive throttle input. The stock power was decent for the small lot we had to work with. The traction control and ABS surprisingly did not interfere as long as the DSC button was disengaged.

The stock LSD was even able to spin both tires okay. The e-brake was able to lock the rear tires up fine in drift, which allowed me to skim the k-walls and put on a show for the crowd.



Overall I was very pleased with how the car drifted. With some lightening and some added power, this chassis can be a pretty good competition drift car. Hmmm… tempting, but don’t think the wifey will appreciate me turning another street car into a track whore. Maybe after my current S-Chassis drift project…

Your e30 m3 had a nice drop, what suspension were you running?

On my E30 M3 I had Eibach Race Springs. But I ended up cutting a couple of coils off of the front spring because it had such a big rearward rake. I felt really bad at the time cutting such a high end race spring kit, but I had to get the stance right. If I were to do it again I would get front coilovers though.

Good stuff!!!  Can I test drive your new car?  :P

John said:

Yeah when I saw the stance it didn't look like you had springs because I haven't seen springs take the height that low. I'm looking at buying a set of ground control coil-overs for my e30 m3 sometime soon.

Interesting...  the s54 motor is very very torquey above 4k rpm, the car s just heavy in stock trim.  the 50/50 weight though has got to help.  Interesting you are on the stock 18 stagger setup, I would assume for drifting getting 2 front 18's in the back may help.  They are pretty easy to source as a lot of the track guys use 4 rears all around to dial out the understeer in the car.  Also M cars can turn off everything but the abs...  which is nice...  take that AMG!

If I was going to drift the e46...  carbon fiber roof and csl decklid to lighten up the car esp in back and help remove some polar inertia, as well getting some lightwieght rims.  That would remove about 250 pounds from the car not including the rims and the unsprung weight.  Then place a 4:10 rear diff in.  These are all easy to source.

Ok those are pricey but some cheaper mods would be to do a csl battery swap (get a mini battery they are the same thing) and remove about 20 pounds over the rear wheels, as well as  4 oem front 18's all around to reduce the contact patch in the back a little.

Unfortunately there is really no good way to tune a s54 motor for more power.  While the internals will take up to about 450hp with no big reliability hit, new exhaust, headers, intake and professional tuning will only really net you about 15 hp, and most of that is the new headers and tuning. If you can get your hands on a csl airbox or if vorstiener ever makes a replica you may get another 10 there.  Other wise intakes do nothing, new exhausts gain 5hp on top but lose 5 hp down low.  SO spend 15k and get a TT or CS kit that will get you about 110hp more.  Take that 335 owners!  your stock internals cannot take more then 70hp before things start breaking, then again it costs only about $700 to get that 70hp....

Bst bmw drifter...  I would take a e36 M3 and place the s54 in it...  better chassis and lighter....

FYI I am a e46 M3 owner....
