Reposting Alex, Traction is a simple function of coefficient of friction between the tire & road multiplied by the weight on the tire. T = CoF x Wt No friction, i.e. ice, no traction. No weight on the wheel, no traction. When the wheel comes down off the bump, it momentarily loses some weight. It may not come completely off the ground but it may only have 1/2 the weight for a split second. 1/2 weight = 1/2 traction. Now why both front wheels go bizzerk into ABS I don't know. If anything, you would think just that one front wheel should activate ABS.

But what you said can also apply to you. Especially after spending all that money on a brand new car. It would be sad if you didn't feel like you did upgrade from your old E36 M3;) Joe -------------------- It seems to me that folks are always the most vocal and opinionated about things that are most closely comparable to what they love. It's like a sibling rivalry thing. I used to have an E36M3. A turbocharged one, even. It was a great car in every way. But, for the last 7 months a 330i has resided in the garage. Sure, the E46 is a bit heavier and not quite as connected as the E36 was. Just as the E36 was to the E30. But, like the E36 at the time, the new car rides better, has a nicer look and interior, better gas milege and is generally a much more advanced and better platform. Not that the E36 was a slouch or a bad car by any means. But to call the E46 330i a "sensory deprivation tank" is a bit ridiculous since it's a lot closer in feel to the E36M3 than any other car ever made, IMO. In fact, that's the thing that struk me when I first drove one - the E46 M3 isn't the successor to the US spec E36 M3. The 330i is. Sure, there are a few things that I think I liked better about the old car but 95% of the new car is better. Sometimes _MUCH_ better. That's just my 0.02. If you prefer the E36M3 then more power to you but let's not be so attached to these things to believe that they are not engineered by man and have room for improvement.. -Matt __________________________________ Do you Yahoo!?

Need it as a template for the bushings. This is the arm that connects the lower diff mount to the bottom of the rear wheel bearing carrier. It is the arm that controls the rear camber and looks like to U-shaped pieces of stamped steel. Thanks, Chris

It indicates that this new coupe will weigh about 3500 lbs. and will initially come with the 4.4-liter V8 with 330 hp. Makes me wonder where the new M3 will slot in. Perhaps, a weight-conscious, performance oriented model ala the e36 LTW with say, 350-hp??? BTW, the article also stated that an M6 is due in 2005 and will come with a 500 to 550-hp V-10!

Lowell, That's all fine and dandy, but ABS sensors do not measure traction. They measure the wheel rotation speed. If a wheel locks up, its rotation speed decreases prompting ABS's intervention. However, when going over a bump/pot hole, the wheel speed should not change much, and if anything slightly INcrease. And that is something that can be accounted for in the ABS brain coding. We are talking about ABS kicking during the mildest of breaking on rough surfaces. I suspect everyone on this list knows what I'm talking about. Even if road imperfections cause momentary decrease of traction, those should not result in lock up. During hard/near-threshold breaking, a bump could reduce traction enough to induce lock up. But assuming a preceding wheel acceleration, it could be coded around in the ABS brain as well. > Now why both front wheels go bizzerk into ABS I don't know. If anything, > you would think just that one front wheel should activate ABS. AFAIK, once triggered, ABS engages all channels (four wheels) regardless of which one was detected locked up. alex f ---------------------------------------------- alex.fadeev@verizon.com writes: > Excellent point the brings up a question that has been on the back of my > mind for a while.

The new 6 will be based on the 5 platform. Traditionally, new platforms weight more than their predecessors for a numbers of reasons, not least of which are all the additional electric/safety toys/gizmos. It would take a miracle for the new 6 to weight at under 3800 #s. > Makes me wonder where the new M3 will slot in. Performance of $$$-wise? Old 6 was anything but budget oriented. > Perhaps, a weight-conscious, performance oriented model ala the e36 > LTW with say, 350-hp??? As long as the 6 costs more than M3 by $10+K, the latter will do just fine. The M5 currently stickers at ~$20K above the M3. > BTW, the article also stated that an M6 is due in 2005 and will come > with a 500 to 550-hp V-10! ....will likely cost three arms and four legs.... alex f

Reposting alex.fadeev@verizon.com writes: > Even if road imperfections cause momentary decrease of traction, those > should not result in lock up. > Why not? This is under braking right? I assume your ABS is not kicking in when you are driving down the road. ;-) You are braking, the brakes are resisting the rotation of the wheel. What is making the wheel rotate? Well.... the ground passing underneath. What happens if there is no more ground, that is, the tire is airborne? Remember the brake is applied - even moderate braking - now you have no more ground to rotate the wheel so it stops due to the brakes. I am arguing it is the coming OFF the bump that trips up the ABS. Going UP the bump, you actually increase traction and it would take more braking to lock up the wheel. Come DOWN off the bump, you reduce traction momentarily. Remember there is less weight on the wheel. If you just happen to be applying more braking force than the new reduced traction can overcome, the wheel locks up and ABS does its thing. Lowell Seaton
