That sound you hear is more money dropping into the suspension piggy bank. Jon From: Steve Nash <[EMAIL PROTECTED]> To: [EMAIL PROTECTED] Subject: Re: Sachs suspension Message-ID: <[EMAIL PROTECTED]> Yes, it is the sporting set that you keep hearing about. It's firm but not harsh. My E30 M3 with a Bilstein/H&R setup is harsh in comparison. I have been driving over bumps that I avoid in the M3 just to feel the difference and they get soaked right up. This is how the car should have been from the factory. Also, it is lower but doesn't have that "slammed" look. It's tasteful looking. This is my wifes car, but I hope she wants to keep the touring. -Steve __________________________________ Do you Yahoo!? Friends. Fun. Try the all-new Yahoo!

So much for my efforts to keep up with routine maintenance...at least I made Hunter Engineering happy. Anyway, it looks like I'm going to have to rebuild the calipers with new seals and guide pin bushings. It appears to be a pretty simple procedure, but I still have a few questions: - Is there reason to spend extra bucks for the BMW dealer rebuild kits instead of the aftermarket kits? (OEM ATE, I assume) I have some other parts to order, so I'm not about to pay the local dealer $30 for two lousy rubber seals, when that will cover the mail order cost of both seal and pin kits. - Is the brake assembly paste essential? Some say that clean brake fluid is sufficient. Any substitutes for the hard-to-fine ATE brake paste? Opinions seem to be mixed about sil-glide. - Lastly, what is the real world practice with regard to greasing the guide pins? The official line is to keep them dry, but I know that many people ignore this. Thx, Herman ------------------------------ Date: Fri, 28 May 2004 08:33:01 -0400 From: "Gary Derian" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Subject: Re: caliper rebuild questions Message-ID: <[EMAIL PROTECTED]> Call me Queequeg. Any quality kit is good. Grease IS essential for a long lasting rebuild. I use Dow Corning 111 silicone grease on both the piston and seals, and the guide pins. ATE has a special brake grease that is as good or better. You do not want any brake fluid past the o-ring. Brake fluid absorbs moisture and will corrode the metal parts. Pack a reasonable amount of grease on the outside of the square seal and inside the rubber boot as an additional moisture barrier.

Message-ID: <[EMAIL PROTECTED]> Steve Nash <[EMAIL PROTECTED]> asked: >I just finished installing the Sach's suspension on my '95 525i and love >the feel. Now I need to do an alignment and order some new tires. The >two I am considering are the Continental ContiExtremeContact and the >Yoko AVS dB S2, both in 225 60 R15. Anyone have anything good or bad to >say about either of the two? How about another good choice that I missed? I very much like and recommend the Yokohama AVS dB S2 tires. As someone else noted, not too many choices are available in that size. For a pretty comprehensive view of tire availability by size, try tirerack.com's pop-up selectors (tirerack also happens to be my tire supplier of choice.) Our '92 525iA has had 225/60 VR15 Yoko AVS dB tires for the last several years. Car was acquired used with a set of 195/65 P6000 Pirellis which truly sucked in _every_ way. I immediately replaced them with a set of the then-new original dBs and loved 'em. When those got a bit tired (last fall, after a normal milage tho I forget the exact figure) I replaced them with a set of the dB S2. BTW, the car has Bilstein Sports on stock springs. I've been really satisfied with everything about these tires. Dry performance is excellent, very well balanced and quite responsive considering the size and weight of the car. Good turn-in, little understear, pretty much zero oversteer :-/ , great feel and feedback without being overly sensitive. Very confidence inspiring, even pushed as hard as possible (on the street.) I'm the sort of driver who looks forward to hitting those onramp apexs as fast as possible and powering out under full 2.5L steam. The sort of driver who spends more time with the tranny selector in 'S 3' than in 'E D'. :-) The vaunted low-noise aspect is impressive, as is the ride, not soft not harsh, just right for me. As is all too common in this sort of situation, the wife's opinion matters :-), but even she has no complaint of them being too harsh. Wet performance is also excellent: drizzly morning today and (just for fun) I tried the wet braking ability with a full panic test stop from ~40mph and found the result even better than I had expected. We had a snowy winter, and while (as you may know :-) the E34 isn't exactly the ideal winter car, the tires performed as well as anything could be expected short of dedicated snow tires. My biggest (and perhaps only) complaint really relates to both car and tires. The E34 has an excellent, stable chassis and the tires stick so well in all sorts of weather I find it near impossible to break the dangity-dang rear loose. Well, it _is_ possible, on snow or gravel, or on greasy pavement at the first rain in several weeks . . . :-) I miss my old E28 which was far more tossable. FYI, my experience with tires is largly based on the vast and uncounted number of sets I went through on my '85 VW Golf, which I drove from new to now (currently @ 817K miles). Over the last 19 years I tried pretty much every H-rated (or better) tire available in 185/60-14. all time fave - Bridgestone RE71 - Tho I never cared much for any other Bridgestones, the RE71 had a responsiveness and delicacy of feedback unmatched by any other tire I've driven ('cept for perhaps the AVS below.) I almost cried when I discovered they were no longer available. snif, snif close second fave - Yoko AVS (the old original AVS model) Another wonderful and superb tire NLA. snif, snif on the Golf now - Yoko Avid H4 - OK for a budget tire, they stick fine, just don't have the senisityivity and feedback of the best. all time biggest disappointment - Pirelli P6 - yeesh, after all those years with its groundbreaking reputation, I finally decided to try a set and boy what a let down. They're a PIG, really horrible compared to even a modest tire like the Avid H4 above! hth, Dan K (who wrote waaaay more than about this than he had intended :-) --------------------------------------------- Trenton, NJ '92 525iA 178K '85 Golf 818K '76 2002 135K '83 GTI 16v 78K km '96 GTI - :-( smashed front --------------------------------------------- ------------------------------ Date: Fri, 28 May 2004 09:25:27 -0700 From: [EMAIL PROTECTED] To: [EMAIL PROTECTED], [EMAIL PROTECTED] Subject: Anyone Ever Buy From These Companies? Message-ID: <[EMAIL PROTECTED]> I'm shopping for Axxis Ultimate brake pads for my [E30] '90 325i. Several people recommended Rob at mpactmotorsports in Danville, but he has not returned my phone or e-mail messages. So I'm moving on. I've found the pads at these three on-line vendors: M3 Motorwerks, Marietta, GA Street Beat, Phoenix, AZ Cobalt Friction Technologies, FL Anyone have any experience with any of these companies? Good or bad? Any other suggestions for reliable sources?
