    ..also helps to start with the lightest chassis E30. Suppose you started with an '84 316 that you just happened to find already caged and stripped on Craigslist over the weekend.

    Stock form already 2345.
    Now, stupid light.
    Target - sub 2100.

        ..and actually it's lighter then I quoted. Starting 2100-ish, which would explain when one of my buddies was able to lift a corner off the ground while removing a lug nut..

              Smelzer I love the pic with the back wheel off the ground. That thing is a tank for what it weighs.

                How much weight would it take off to remove the power steering/swap out the rack for an E36 steering rack? What about a manual window conversion?
                '93 E30 325ic - CURRENT | '99 E36 M3 - SOLD | '94 E34 530i - SOLD

                  I weighed my power steering set up and it was pretty close to 5kg. Pump, lines, belt, reservoir and fluid. That was from a 323i/M20B23.

                  If you delete AC and PS you can also delete the accessories pulley off the crank which would have to weigh at least 1lb.

                      As stated before, you definitely need to be aware of what chassis you start with. There is huge differences in base weight through the years. The 84-early 85 are by far the lightest US spec cars, while the plastic bumper cars were way heavier by the end of production.

                      If you are wanting to go light, your best bet is finding a diving board car and then put it on a diet.

                      My own PRO3 car started as an early 85, and has always had trouble meeting the minimum weight requirement in the class (2650), and that is with ALL the stock sound deadening on the floors in the passenger compartment and trunk.. Unless I add over 100# of steel, I won't pass at the end of a race.

                          yeah you're definitely right.

                          but for me its not about having the lightest e30 possible, its about how light I can get MY e30 specifically. otherwise I wouldn't have gotten a vert, or an e30 in general for that matter.
                          it all comes back to just having fun, not trying to win any trophys or anything like that.

                            tracking it because my buddy got me addicted the day he invited me to an open track at willow. I was hooked instantly.

                            gutting it because a) weight reduction for the days at the track obviously, and b) a fully gutted and painted interior looks nicer to me than a reupholstered oem interior. "not every show car is a race car, but every race car is a show car".

                            I know some people might think it's silly to track your daily (especially when your daily is a vert) but theres nice weather every day in SoCal and willow springs is an hour away... so when you think about it, a track ready DD vert is actually perfect. at least for me anyway.

                              thats the great thing about willow. the open track days are basically "do you have a helmet? is your car leaking oil? okay you're good".

                              now i'm not saying i'm gonna half ass all the safety aspects of a track car, but when you're just showing up for open track days, you don't have to worry about all kind of rules and regulations. if I get any more hooked though, I can definitely see myself building some sort of competitive track car in the future.

                                My 2/87 eta, sitting next to an 84, last weekeend, is #200 heavier. Kevin's #120 under weight, I'm nearly #100 over, and from looking at them, there is no difference whatsoever. Well, except for my beer belly...
