#2. Wheel Balancing and Weight Placement - from Monty Baugh
Top
Date: Thu, 12 Oct 2000 13:50:36 -0500 From: Monty Baugh <mbaugh@telecom-management.com> Subject: Wheel Balancing and Weight Placement If a tech/mechanic tells you it doesn't matter where you put the weights (inner or outer), he doesn't know what he is doing. To be dynamically (spin) balanced, adjustments must be made both relative to the wheel's rotating axis and relative to the distance from its mounting point. I.e. consider a wheel that is perfectly balanced in a static situation (lying flat on a bubble balancer). Add equal weights to the wheel at opposite sides, but one on the front wheel face, and one on the rear. The wheel will still be in static balance, but when the wheel spins, there will be a angular moment between the wheel's rotating axis and a line (axis) between the two added weights. This will make the wheel try to wobble. A good digital spin balance machine will show locations for inside and outside weights after the uncompensated spin. MBaugh

My mechanic uses these, but he also takes some aluminum tape (this is like foil with adhesive on it) and covers the weights with the tape to keep them from going anywhere. Actually I believe it was Jon Van Houten who gave him the idea to do it. Anyway, I have no problem with weights falling off as a result. As for looking over the tech's shoulders, I don't know about that, but my mechanic enlists me help him change the things !! Goes faster with two sets of hands.

#4. Wheel/Tire Survey - from Heckendorf, David

Date: Thu, 12 Oct 2000 14:54:42 -0400 From: "Heckendorf, David" <DHeckendorf@broadband.att.com> Subject: Wheel/Tire Survey Since I'm now looking at new tires for the '98 E36 M3/4 (presently stock suspension, save sways, and stock wheels/tires, 7.5x17F & 8.5X17R M-Contour IIs), and I'm tired of burning $1,000+ worth of tires at the track and not being able to rotate, I'm looking to get both track wheels/tires and potentially upgrade/replace my street wheels/tires. For street: 1) I know that some of you run 8.5x17 stock rims front and rear, does this require any spacers or rolling of fenders? Since I've already had one of the 7.5x17s bend on me, do we have any idea if the 8.5x17s are less prone to bending?? 2) What tire Manufacturers/Models/Sizes are you running on stock rims (either 7.5 or 8.5) and did any of it require rolling/spacers.? 3) For street, I would prefer to avoid spacers (rolling I can live with as it's only once), what stock/after-market options/sizes/offsets/etc... fit this parameter. 4) I've been looking at the following (including some lower performance ones because of getting track wheels/tires) opinions on these or others??): (Ultra-High Performance) Manufacturer Model Size Price(Tire Rack) Kumho ECSTA Supra 712 245/40-17 $109 Bridgestone Potenza RE730 245/40-17 $141 Dunlop SP Sport 8080E 245/40-17 $208 Yokohama A022 H0 245/40-17 $215 (Max Performance) Yokohama AVS-Sport 245/40-17 $171 Pirelli PZero Asimmetrico 245/40-17 $219 Dunlop SP Sport 9000 245/40-17 $226 Bridgestone Potenza S-02 Pole Position 245/40-17 $235 BF Goodrich g-Force T/A KD 245/40-17 $245 Pirelli PZero Rosso Asimmetrico 245/40-17 $249 Michelin Pilot Sport 245/40-17 $257 For track: 1) I've been limiting my scope to Forged options and since they're only track rims, they don't have to be fancy, just strong and light and the side benefit is that they are less expensive than the fancy ones. This has led me to IFG A5s and SSR Integrals: IFGs: PCD Size Offset Hub Cost 5 x 120 17 x 8 F 41 F 72.5 $430 17 x 9 R 42.5 R 72.5 $440 SSR Integrals Size Offset Hub Cost 17 x 8 ?? ?? $309 (Tire Rack) ??Others?? 2) Aside from repairability, any advantage to the more-expensive multi-piece wheels (Fikse, Forgeline, Kinesis, etc...) are there others that I'm missing? 3) It's my understanding that Fikse Wheels can have the spacers attached to the back, nice feature, can/is this available on other brands (or can it be done)? 4) Since this is my first set of R tires what would be a good first R tire choice (I'm thinking Kumho or Yoko)?: Manufacturer Model Kumho Victoracer v700 Yokohama A032R Hoosier A3S03/R3S03 BFG g-Force T/A R1 BFG Comp T/A R1 Goodyear GSCS Thx!!, Dave

They were my (& several friend's) first R-tire, and I still run them. Not as sticky as the Kumhos & Hoosiers, but then I'm not looking to get that few tenths. The Toyos wear well, and are fairly predictable. Currently, they are only available in 235/45/17, but by next year should be available in 235/40/17, and in 255 & 215(?) sizes as well (I have an email from a Toyo rep at home I can double check. > Yokohama A032R Although I've not driven these, several of my friends have and like them as well. I believe they make a good first R-tire as well. Performance & wear are similar to the Toyos, form what I hear. Cheers, Jim Bassett 1998 M3/4

I run 17x8.5 double spoke II's all around with 245/40-17 BFG G-force KDs. They rub the front strut just enough that I need spacers. No fender rolling required in the rear, though. > 4) I've been looking at the following (including some lower > performance > ones because of getting track wheels/tires) opinions on these > or others??): I *love* the KDs, but they wear fast and are very noisy at certain speeds. After about 9,000 miles and maybe 80 autocross runs, they're pretty worn. Another two autocrosses and the rest of the fall's driving should finish them off. Unbelievable grip and terrific predictability with these tires. A friend has the Yokohama AVS Sports and is extremely happy with them. They're probably the next tires to go on my car. > 4) Since this is my first set of R tires what would be a > good first R tire > choice (I'm thinking Kumho or Yoko)?: I will probably go for a set of Kumhos next year myself. I rode in Wayne Miller's car for an autocross run and was blown away by the difference in grip. (He did have some suspension mods, though.) Dave

David: I went through the same process about 2 years ago. My selection - Fikse Mach 5 wheels. 17 x 8.5" on all corners. I got mine anodized. These wheels are easy to clean up after track sessions, and the spokes are even large enough that you can get at the brake calipers and check pad wear. Their biggest advantage is low unsprung weight. For tires I really like the Kumho V700s. They grip amazingly well all the way to the limit, and will let you know when they're about to let go. They really like to be heat cycled, and you *can* overdrive them. If you let them get REALLY hot you can scrub off the rubber quickly (ie short life span). Once you learn their limit they last about as long as the BFGs and much longer than the Hoosiers (on my car anyway). With this wheel tire combo you'll have to lightly roll the rear fenders, but once that's done you have a killer combo. Amazing grip and virtually no understeer......

Since I've already had one of > the 7.5x17s bend on me, do we have any idea if the 8.5x17s are less prone to > bending?? Depends on whether the 17x8.5 rims are forged or cast. Cast rims are more prone to bending, forged rims are more expensive. Pick your method of wallet-drainage. > 2) What tire Manufacturers/Models/Sizes are you running on stock rims > (either 7.5 or 8.5) and did any of it require rolling/spacers.? My '97 M3 rides on 4 245/40/17 Toyo Proxes T1-S tires. Around $180/per, I'm fairly happy with them. Good grip, good wear. The shoulders have worn down a bit faster than the rest of the tire, but that has more to do with 2 of us autocrossing the same car all season long. > 3) For street, I would prefer to avoid spacers (rolling I can live with as > it's only once), what stock/after-market options/sizes/offsets/etc... fit > this parameter. I chose to go forged, and have 4 Fikse FM/10's in 17x8.5 offset 37.5mm. No fitment issues, no rubbing, no fender rolling, no spacers. Bolt 'em on and drive away (just not mine!). No track tires or rims, so I won't be able to help much there. Andrej '97 M3

I would like to share my experience with the UUC Tubular Sways. I replaced the Dinan sways on a Dinan stage 3 suspension system. Road test has minimal to no sway, very flat handling at speed. A major improvement over the Dinan sways......WOW WEE! Excellent build and finish quality with trick adjustable rear links. My service guy called Rob at UUC with linkage adjustment questions, he was a big help in a very nice way and the rear links were correctly adjusted with no contact and no noise. Be sure to Call Rob at UUC if you need assistance with adjusting the rear links. The UUC Tubular Sways, UUC Short Shifter and Tranny Mount are all happy together in my little 97 M3/4.
