If the tire is rolling, there is a static friction at the tire contact patch and a dynamic friction at the brake pad surface. 2. If the wheel is locked, there is dynamic friction at the tire contact patch and static friction at the brake pad surface. Ok, static friction > dynamic friction. But this still doesn't explain why rolling tires stop better. I think you need to add that the dynamic friction of brakes is bigger then the dynamic friction of the tires. Slipping brakes are able to have more friction then skidding tires. Otherwise, I thought that threshold braking stops faster then ABS braking?

The intercoolers were designed (sized) knowing that they would not have 100% direct air flow into them (The intercooler on the Porshe turbo is designed in much the same way). The intercoolers are made quite large because of this problem of space behind the front bumper. and work perfectly for street use and for "normal" track use. Under extreme conditions the intercoolers cannot keep up and the power will fall off a bit. this is a problem with many turbocharged engines. >These cars suffer >from very high fuel consumption in a country with costly fuel. I'm getting 24mpg combined city and highway from a car that is not totally broken in yet (mileage should improve). > Lastly, the >turbos are apparently undersized and modifications are barely able to >generate 270-280hp...nowhere near the 300+ that many tuners are claiming. That's completely untrue. The turbos are K03 units which are the same units as used on the 1.8t. Maximum boost from the K03 exceeds 1.0 Bar. The 1.8t can easily reach 205 hp using 1 bar boost. that's a 55hp increase from a 4 cylinder using one turbocharger and one intercooler. You don't believe that twin K03's acting on 3 cylinders each can produce a 55hp increase at 1 Bar? I have seen German dyno results of these cars to prove it can and more results that prove they can hit 325hp with exhaust tuning. One tuner has an S4 making close to 400hp with slightly larger turbos and intercoolers. >Guido said he would take an M3 anyday over these Audi's.

FWIW, BMW is working on a rear spoiler for the Z8 for precisely the same reason. I saw them testing it at the Nurbergring. The curved design of the rear end happens to create lift at high speed. From what I have read (I've read a lot) the accidents were due to lifting off the throttle abruptly in high speed sweepers. Steve, why don't you try that in your 911 turbo and tell us if the same thing happens to you. Lawsuits like this are exactly why Porshe has had to sanitize its cars. >(6/99- SportAuto did a comparative test of stock vs Movit brakes on >an Audi 1.8TT.

Now this really doesn't mean much here in the states as there's >little chance these cars will be driven at drivers schools where you'd be >doing this kind of high speed braking. It is significant in Germany.) It's not even significant in Germany. Who makes consecutive stops from 124mph time after time ANYWHERE? Five stops from 124mph without a chance for any cool down time, you don't even have those extremes on the track (at least any track I've been to). Big brake kits are great for the track but a total waste on the street unless the motive is to look cool. I've yet to see anyone use up stock brakes while out for a drive on public roads, if so, they should be locked up. The brakes on both my '95 M3 and my S4 are both fantastic on the street with the edge going to the S4's twin piston 4 pad units. They are fantastic. On the track I'm sure they both need upgrading with Pads at a minimum and possibly a big brake kit to get the last little bit of performance. >Now, before I get accused of bashing Audi, let me say that they make a fine >road car with excellent value.

What about the BMW control arms that snap? What about the 50+ cases of the body pulling through at the rear subframe mount in the E36s? The Z3 fuel pump fix that requires the dealer to slice the carpet and Velcro it back in place? Our 3 Audis have a combined 60,000 with not one problem and never having been to the dealer except for oil service. Our E36 325 spent over 30 days at the dealer for problems the first year of ownership. Our Z3 had the cylinder head off 3 times to fix an idle problem that was never corrected. Audi quality has come a long way and I actually get treated like a human being at the dealership to boot. Nothing like having them appreciate your business.

I have realized how much fun the E30 M3 is in the snow. Now I want to do ice racing since I am in the Boston Chapter. Anyone who does it have any opinions on tires? It would be 205/55-15's. The 190's seem great. I looked at Tire Rack and they have The Dunlop Graspic HS-2 for $62 each, which are $20 less than the next cheapest tire, yet rated one of the highest for snow traction.

How about a rent to own deal? I wouldn't put many miles on it. Just to a few trips a year to a place near an apple orchard in West Virginia and maybe to a horse track in Maryland several times a year. And it would be only on weekends. Well except for one week in Oct. I would need to go to South Carolina for a little vacation. And there is a week at the end of July that I'd like to drive to Quebec for a jazz festival. Nothing special. Then there's a little trip to Waterville next year. And maybe a trip somewhere in Mid-Ohio. I haven't been to Connecticut in a while. I'm sure I can find a place to spend the weekend there. I haven't visited NY in several months. There must be a place where the car would feel comfortable at. But that's it. Really. ...steven ------------------------------ Date: Thu, 27 Jan 2000 00:04:35 -0500 From: Jacob Steijn <[EMAIL PROTECTED]> Subject: [uuc] Re:E30 Dash Light Problem I disagree. My E28 has been doing this since I got it in October '96. No battery problems yet. I think it's a sign of a less than perfect ground at the instrument panel or between the alternator and the chassis or engine. When I last replaced my passenger-side motor mount I cleaned the engine/chassis ground lug, and now my warning lights go out when I release the parking brake or when I rev the engine, whichever comes first. Others have testified that cleaning up the alternator case ground lug fixed this problem. Don't blow money on a battery unless it tests bad.
