Date: Mon, 8 Jan 2001 20:52:34 EST From: TFRM3@aol.com Subject: Eibach vs. stock spring rates <<With all this talk about suspension for M3, has anyone tried to just swap the front spring w/ relatively mild aftermarket springs like Eibach pro-kit and leave the rear stock since the spring rate of the stock springs are pretty high already?>> A little known fact is that Eibach rear springs are almost exactly the same as the stock European rate, intentionally. The "almost exactly" disclaimer is that the term "European" is a bit dubious when dealing with prototype cars, European cars, etc. So it would be imprudent to quote the rate, because someone would surely question the validity. Suffice to say that testing 7 years ago determined that Joe Tan has a good idea! (no slight intended) The reason this works on the rear is the progressiveness of the geometry still prevents bottoming at the lower ride height. The front suspension is not progressive, so the spring rate is higher than stock to prevent bottoming, about 12%. The Eibach directions show to cut the front bump stops, but not the rear, and only for stock shocks. I recommend cutting all four bump stops. I did a lot of research before I chose springs for my car, I am not completely biased towards Eibach, I just have a lot of info.

Dude, that's some fatty weed you're smoking. :) Admittedly, I came from a much better handling car than the stock M3. (A Miata and an S2000.) With the mods I've done to the car (STBs front and rear, stock sway bars, h&r coilovers, k-mac camber plates, gc rear shock mounts and tc kline trailing arm bushings, the M3 still rides better than either the Miata or the S2000 over most roads (except for really big drop offs) and handles better than either as well, both on the street and on the track. Remember, my M3 isn't my race car... it's what I drive to work everyday... I prefer the ride of the H&Rs to the floaty (admittedly 53K old) stock suspension. -kit, with a comfy butt 97 m3

It is not necessarily caused by putting a stiffer suspension on the car. It is caused by putting a set of springs that are not stiff enough for the thicker aftermarket sway bars. The sway bars then do more work than it needs to and breaks the mounting tabs. Just a thought of mine. Anybody else have an opinion on this? Seth Thomas www.m3ltw.com www.m3power.com

If you're curious go to dsm.org Scott Hemauer '94 325i '98 ML 320 '95 Mitsubishi Eclipse GSX (all wheel drive) '90 Eagle Talon TSI (all wheel drive) >>>>>>>>>> The first part about biasing car brakes so much toward the front that it could pick up the back wheels is plausible I guess since it is done with ease on my bike, but I have to admit I am somewhat confused how the same car (a front wheel drive Eclipse/Talon/Laser) can pick the front wheels up in a launch on tarmac with V700s?!? Light them up maybe, but pick them up? >>>>>>>>>>

I like ABS. :-) I think it is one of the best automotive inventions in the last 30 years. I'll argue that ABS can stop a car quicker than any human every time on any surface. Pretty bold statement I know ;-) Motor Trend Magazine did a test of ABS vs. threshold braking. I wish I could find the issue now! I have it somewhere if you give me time to dig it up. It is the famous one with the 3 Dinan M3's. Motor Trend used a Mercedes Benz S600 and about 40 sets of high performance tires. They tested the S600 on about 8 different surfaces - dry, wet, sand, gravel, deep fresh snow, hard packed snow, scarified snow, and glare ice. They tried 3 different braking techniques - ABS, threshold, and full lock. The drivers were Motor Trend test drivers. Extremely experienced drivers. In every single case, ABS beat both threshold and full lock except for two and one tie. The only time ABS lost by a slight margin was in gravel and on the glare ice. And I think the deep fresh snow was a tie with full lock. Threshold braking never stopped the shortest. I wish I could find the article so I could quote exact figures. I certainly agree that ABS allows you to steer and brake without losing control. That is a huge benefit. However, did you know cars with ABS rear end more vehicles than cars without ABS?? It is almost unbelievable but true. I don't know if anybody has figured out why yet. Maybe people driving ABS equipped cars think they can stop much shorter and get overconfident? Or another theory is people get scared in panic stops when the ABS starts pulsing the brake pedal and they LET OFF the brakes! Bam! Mercedes Benz invented a panic stop feature to ABS. It has a sensor that detects how fast you initially depress the brake pedal. Say in a panic stop, you react and slam on the brakes. That is human nature. But this is where people go wrong and either lift off the brakes when the ABS kicks in or don't continue to press further down on the brakes. The MB feature takes over and continues to apply the brakes harder whether you want to or not. MB assumes you started the panic stop for a reason and had better stop immediately using full ABS. Has anybody driven a late model MB? How does it feel when the brake pedal goes clear to the floor without any effort? I can imagine it must freak you out. OK, enough for now. Anybody have that Motor Trend article handy? Sean? Didn't we debate ABS a couple of years ago? :) You still have your old posts? Lowell Seaton '95 M3 Dallas, Texas
