Message-ID: <[EMAIL PROTECTED]> Ahhh, this story brings back memories..... One comment I will make is that this stretch of highway is, IMO, a tad too urban for these speeds. Clarence West Bend, WI *************************************** Heartland man accused of driving 145 mph on I-94 By TOM KERTSCHER [EMAIL PROTECTED] Posted: Jan. 3, 2005 Caledonia - A 25-year-old Waukesha County man tore into the new year - at 80 mph over the speed limit - and wracked up a possible $1,230 in traffic tickets, the Racine County Sheriff's Department said Monday. Timothy M. Knick of Hartland was pulled over while driving a turbo-charged Subaru WRX on northbound I-94 near Highway K for driving 145 mph in a 65 mph zone, Sgt. Brian Londre said Monday. That ticket was for $863, and another for reckless driving added $367, for a total of $1,230, Londre said. The new year was barely five hours old at that point. There was no evidence that Knick had been drinking. "That's a good thing," Londre said. Tickets have been issued to many people for exceeding 120 mph, Londre said, but he hadn't heard of anyone reaching 145. Court records show Knick was found guilty of speeding in Milwaukee County in 1999 and twice in Waukesha County in 1997. His record at the state Department of Motor Vehicles, which clears citations after five years, is clean. Knick will have an opportunity to contest the new tickets in Racine County Circuit Court. He could not be reached for comment.

Rich: no bumpstops on the fronts, bumpstops on the rear. 2. James Clay from Bimmerworld (from whom I bought the shocks): no bumpstops anywhere, and that's how he runs his car. 3. Bilstein USA: bumpstops everywhere, because the Bilstein shocks for this car has no bumpstops. I confirmed the part numbers and my car with the Bilstein tech (Steve) --- he even offered "E46" when I told him my model year. 4. This one's still open: any takers for front bumpstops, and no rear bumpstops? :-) I guess I get to experiment now, and perhaps use my spring compressors more than a couple of times. What's the safest thing to try first? I assume bumpstops everywhere first, and see if I hit them prematurely? Then there's this other thing I read on the H&R site which says that their springs are designed with bumpstops in mind, since their effective spring rate takes into account the presence of bumpstops. I didn't know bumpstops were produced with any kind of consistent spring rate. --Andre ------------------------------ Date: Tue, 4 Jan 2005 10:27:29 -0800 (PST) From: Andre Yew <[EMAIL PROTECTED]> To: [email protected] Subject: Re: Bilstein bumpstops ...

One more datapoint. I called up Turner Motorsports, and asked them about this, and they also recommend #2: no bumpstops front or rear. --Andre ------------------------------ Date: Tue, 4 Jan 2005 13:04:55 -0600 From: "Dave Miller" <[EMAIL PROTECTED]> To: "'Andre Yew'" <[EMAIL PROTECTED]>, [email protected] Subject: Re: Bilstein bumpstops ... Message-ID: <[EMAIL PROTECTED]> It sounds like you have your answer - no bump stops. Turner usually has good advice. The way to tell if you need them is to put nylon cable ties tightly around the stem about three inches from the top. After a hard run, see where they have moved. If they are not at the top, then you don't need bump stops. If they have moved to the top, you need bump stops. I ran Bilstein Sports on my E36 for about 5 years, with Eibach springs. No bump stops on the front and bump stops on the rear. I cannot speak for E46 Bilsteins.

Message-ID: <[EMAIL PROTECTED]> I believe Turner and Bimmerworld both know what they are talking about, and Dave offers very good advice below, but going with bump stops in the rear almost "can't hurt" (aside from added weight and an increase in spring rate) and potentially could "really help" avoid major problems. Also, some of the BMW bump stops also are integrated with holding the dust shield in place so that is another issue. But, do what Dave says if you want to know for certain, but be careful testing. You don't want to punch through a rear shock tower or something similar. Also, in the front, you aren't "going without bumpstops". The front Bilstein strut inserts have the bumpstop built into it internally. You are simply not reusing the OE bumpstop as it wouldn't fit nor is it necessary to be duplicative.

Message-ID: <[EMAIL PROTECTED]> Bilstein strut inserts are usually built upside down with the piston up near the strut mount. That design has no room for an external bump stop and has its own built in to the bottom of the insert. This style is easily identifiable by the large diameter tube that fits inside the spring. Bilstein rear shocks are usually built the normal way and have room for bump stops. Removing the factory stops is OK as long as something limits wheel travel before the suspension joints bind or the oil pan hits the ground. Tall bump stops known as packers are useful for achieving variable rate springing, and to raise effective spring rates with stock springs.

My shocks definitely do not look like a monotube design (ie. two tubes, with one tube slightly smaller than the other telescoping out). Instead, the Bilstein front strut looks like a bigger version of the rear shock. There's the big strut cylinder, with a long, thin, metal rod with a threaded end that comes out from the middle. The Bilstein tech also mentioned that it was a "high-pressure twin-tube" design for this car. I'm not sure if that makes sense. Their own app note for this shock doesn't require a bumpstop front or rear, however (while it does require it for certain other BMWs, like the rears of an E30). I think I'll try no bumpstops with the zip-tie markers, and let everyone know how things are going in a month or so, or whenever a I hear a loud bang ... whichever one occurs first! --Andre ------------------------------ Date: Tue, 4 Jan 2005 15:50:21 -0500 From: "Gary Derian" <[EMAIL PROTECTED]> To: "Andre Yew" <[EMAIL PROTECTED]>, <[email protected]> Subject: Re: Bilstein bumpstops ... Message-ID: <[EMAIL PROTECTED]> Collapse the strut by hand and see if it mushes to a stop or goes clunk. Mush means there is an internal stop. Clunk means no stop. There should be something soft making first contact at the end of the suspension travel.

That's such an obvious thing to try out, I should have thought of that! --Andre ------------------------------ Date: Tue, 04 Jan 2005 21:57:03 +0000 From: "Gregory Bradbury" <[EMAIL PROTECTED]> To: [email protected] Subject: 1972 BMW turbo prototype Message-ID: <[EMAIL PROTECTED]> OK, to those with great memories of older BMW's and other cars, I need someones expert help.
