#1. Spare Tire question: part 2 - from Newman, Christopher
Top
Date: Wed, 31 Mar 2004 12:37:18 -0500 From: "Newman, Christopher" <CNewman@LSAC.org> Subject: Spare Tire question: part 2 Thanks to everyone who responded to my initial question (personal thank you messages also sent). This leads to a few follow-up questions: If you put a 17 X 7.5 wheel (with either a 225/45-17 or a 245/40-17) on one rear side, and a 17 X 8.5 (with a 245/40-17) on the other rear side, is the car going to handle poorly because of the different rim widths and/or tire sizes ? Did BMW make the spare the same size as the front to save space and weight, and because they figured if you got a flat in the rear, the spare would only be a temporary fix ? Has anyone out there used their spare on the rear and kept it that way for a prolonged period of time ? If so, any ill effects ? As always, thanks for any feedback.

Date: Wed, 31 Mar 2004 12:44:10 EST From: AVUSM3@aol.com Subject: re: Cordless wrench for wheel bolts Marc - Once you go cordless you'll never go back! I've been using a Milwaukee for about 2 years and I love it. http://www.minutemantool.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=MTR &Product_Code=mi9079-22 It's pretty torquey and comes with two batteries which is enough to change the wheels on quite a few cars over the course of a weekend. I've also been using a torque stick for a few years and find it very handy. If you get a stick with an 80 lb rating then you will typically find that it actually torques the lugs to about 65 lbs. This is perfect because it allows you to torque them to 65 lbs while the car is in the air, then drop it down and do your final tightening with a torque wrench with the car on the ground. http://www.procutinternational.com/html/torqstik/tq_list.html http://buy1.snapon.com/catalog/pro_det.asp?search=true&item_ID=68728&PartNo=ts kt4580&group_id=2219&store=snapon-store&tool=all Of the two sticks I like the snap-on one better because you can use different sized sockets (for friends with non-BMWs), and you can also use thin wall silver sockets for wheels with small opening like SSR Comps. John Date: Wed, 31 Mar 2004 02:05:21 EST From: Msebmwman@aol.com Subject: Cordless wrench for wheel bolts Okay; I'm ready to make the jump. I'd like to buy a cordless impact wrench to take my wheel bolts off and also put them on. In addition, I'd like to find a socket for it that will limit torque that is applied to the bolts before the 80 or so lbs-ft that I use to torque my lugs. I'd like to be able to use this at home as well as take it along to the track to change the wheels prior to and after a track day. Any recommendations out there please including online places to buy? Also for the "torque stick" or a set of them? Thanks very much Marc 95M3 and itching for cordless relief!

The 225/45-17 and 245/40-17 tires have virtually the same diameter, so putting the spare on the rear shouldn't cause any negative driveline issues. Handling obviously won't be ideal since the contact patches will be different.

I honestly don't think in some cases you have time to include the reaction time of your brain recognizing a piece of tape to correct - isn't that supposed to be 0.400 seconds Jimmy P? I don't think you can drive only one way and I don't think shuffle steering can't work. In a perfect world you are thinking well enough ahead and anticipating your problems so you can act instead of react. But in really hairy situations I know I snap the wheel to straight and back into the turn without thinking about it and faster than I could process something visually - this is a quick correction that doesn't lead to a tank slapper because it was imprecise or held for too long. I don't have the skill to know where straight is around VIR with 17 turns and 17 prepositioned or an infinite number of shuffle-steering hand positions. I don't auto-X more than once a year (and never seriously or successfully), don't intentionally drive rally style but I can usually get the job done in the gravel, and the seating position, steering wheel height and reach, and leg position in my car is set exactly the way I want it. Other situations require a different bag of tricks, but even in cramped quarters of some other cars I have driven I think I tend to leave one hand fixed, even if it is the only one on the wheel at times. I am not good at letting go of the wheel and I don't think I have ever done it - 2 broken thumbs later I still go down fighting for the most part - NOT a good thing. Thanks for everyone's input (wrong or right ;-)) and perspective. I just thought the article was perfect and worth the discussion at the beginning of the race year - even if all it does is make you think a little. And of course you can do whatever you prefer as long as you are not my student. 5 out of 10 as Blake said...

Bruce Leggett just pointed out that there seems to be some defintion lapses here. Shuffle steering that I think James was referring to, and which is also a huge peeve of mine, is when the hands never find the same place on the wheel twice (or at least close to that). I described a form of Shuffle steering in my last email, but I cringe when I call it that. One hand is always in the right place, giving you a feel for what is or isn't straight ahead. I sure hope that the BMW Performance center doesn't teach the former (hands always moving), if so, I will have lost a large amount of respect for the program, simply because it is dangerous. Rally drivers aside (since they are ALWAYS sideways), keep at least one hand in the 3 or 9 o'clock position, and you will be faster and more confident on the track.

First, if the pinging is at 4 krpm, which is likely, then you are not even close to maxing out the stock injectors. Next, be aware that many '95 M3s are "ping sensitive". There was a survey done a few years back, and over half the '95s reported pinging. Be aware that JC has an "anti-knock" version of your chip available for use with the Euro-HFM. My car pinged pretty badly with the "standard" software, but is ping-free with the anti-knock chip, and I picked up 10 hp and a broad-band torque increase on the dyno with it. Alas, there is no anti-knock version of the chip available with up-sized injectors. So, if you upgrade injectors, and still have pinging...you're screwed. You might want to sit tight for a bit...check for vacuum leaks...and see if the pinging goes away. If that fails, you may want to consider the anti-knock version of the chip.

Instructors Beware: In the course of my experience in driver's ed, I was consistently using a fixed hand position. I found it easier to be consistent at turn in and didn't realize the advantage for spin recovery. I had one instructor comment negatively on this technique and encourage me to practice shuffle steering on the street. He made it sound like an advanced technique. So, I fiddled with shuffle steering on the street until I could do it smoothly. You can imagine the next instructor's reaction, can't you? "DON'T LET GO OF THE WHEEL!" I was a little surprised at his reaction. Naturally, I went back to a fixed hand position with him. Bet you can guess what my next instructor told me about shuffle steering? At this point, I use a mix. I normally do not move my hands on the wheel. However, on some corners, I reposition them just prior to corner entry. An example of this is Oak Tree at VIR. If I could get enough rotation with less steering input, perhaps this would not be necessary? Tim 95 M3

From my years of BMWCCA DE attendance I found that the opinion of shuffle steering rests with the individual instructor, not the sponsoring chapter. Even within the same event have I heard differing opinions! Generally, the skidpad instructors have been opponents of shuffle steering ("you lose your reference point when things get too busy"), while the track instructors have varying opinions. It's tough for beginner/intermediate students when the skidpad instructor chastises them for using shuffle steering, after they've been spending each track session with an instructor who is telling them that unless they shuffle steer, BAD things will happen. Advanced students normally get more leniency from the instructors. Regardless of what technique you use, don't wait for track time to practice it. Practice your technique every day that you drive, so that it becomes a natural thing. If you're a one-armed wrist steering driver on the street, how can you expect to transform into a two-handed, 9-and-3 (or 10-and-2) driver on the track?

I would heavily pad the front of your helmet with high quality roll bar padding available from HMS and TMS among other vendors. If it's your street car I would avoid wearing the helmet on the public highways as I have done this in my street legal IP car and it gets more attention than most anyone ever wanted... that said your forearms will really, really hurt your face and your forehead may be enough to crack your forearm.
