  • [Project] FS BMW M3

    I guess it's time to start this so I can stop spamming the Daily thread with it. The Camaro is slowly coming along but in the mean time this is what I'll be running this season. A very early 2002 M3, built in 8/2001 which was one month too early to get the factory strut tower bar (relevant). I've decided to run this in F Street against all Mustangs, Camarobirds, E9X M3s, and a few other cars.

    E9X M3 - about 150 lbs heavier than an E46 if optioned correctly and can run 18x9 and 18x10 wheels with more camber instead of the E46s with 18x8 and 18x9.5 and -1.0 to -1.5 up front. 70 hp more as well. Downside is it is much bigger
    1LE Camaro - more grip, more weight, more power, but wider
    Mustang GT - good power, weight, and grip, newer cars have IRS

    Last year a full weight E46 coned away a title winning run over a 1LE, so the speed is there. Locally I've been 1.2-1.5 seconds off the fastest cars in class while running worn out old no-name all seasons. The only time I drove on a good tire was an RX-8 I've never sat in before which I put 3rd of 163 cars, running the fastest time with John Heinricy in the car.

    This year I will be going to a real tire, either the BFG Rival-S or Bridgestone RE-71R. I will be going up 20mm in width both front and rear which should be worth around 2 seconds by itself. In addition I've replaced my 100k mile suspension with new Koni Yellows primarily for their adjustability. That process revealed that I've been running with a completely blown left front strut which may have led to the slight mushrooming of that tower. That will be fixed along with a new strut bar which should help minimize camber loss while cornering.

    I am also installing a Ground Control 32mm hollow front sway bar that is infinitely adjustable within it's range for both stiffness and preload. After seeing it in person the cost is 100% justified being a chromoly bar with rod-ended links adjustable for length. If I really want to toy around I can play with the preload to adjust the crossweight of the suspension using the bar, obviously with some side effects you wouldn't normally see just from corner weighting. The last part I'm waiting on is the new exhaust which should be shedding over 60lbs from the car while freeing up some power.

    So this will be the new running diary for my progress.

    First day with it

    The mushroomed tower. The ridge about one bolt diameter outside of the lower left stud should not be there

      Nice project. I've really wanted one for a while but as far as practicality goes I think I'm going to buy a Subaru instead.

      Hopefully going back to med school once I graduate so I won't have time to put in the maintenance an M3 requires.

        That's exactly why I don't daily it any more. It really was the perfect daily for 25k miles, but I couldn't keep up with everything the way I wanted to when I was in and out of it everyday. Maintenance became when I could get a day free and the car was filthy inside and out.

              It's not a European term, it's the SCCA's classing index(as he states F class street). This is a project I'm looking forward to following!

                  It's also the reason they sound like a tired vacuum cleaner stock. It sounds better with the windows up because at least then you can hear the induction noise.

                      Threw the reinforcement plates in yesterday along with the new front sway bar. Along with the strut tower brace I'm having a hard time knocking both of the strut towers in as far as they go. I'll have to experiment with lifting different corners of the car in order to max out camber on the passenger side again. Also finally decided on ordering a set of Bridgestone RE-71R tires since the Rival S is still a month out. Went with a 255/35/18 up front under the theory that lowering the front of the car slightly should help decrease understeer, and the 255 shouldn't be too much of a squeeze on the 8" wheel. I'm trying every trick I know to dial out the understeer including running a bit of toe out up front.

                        Tires are in. Need to find time to get them mounted, set camber and toe at home, change the spark plugs, change the diff fluid, and remove the rear shocks to set rebound. Hopefully I'll have time to wash the car and register it in time too. I'll be testing the data logger in my DD on the way to work so hopefully I'll get that figured out before Sunday.

                          To me FS= For Sale
                          I would guess for your use FS= Factory Stock?
