    Furthermore, servicing such as bleeding the slave cylinder in place is nearly impossible. Removing and replacing it is a total pain. There just is very little room in the 02 transmission tunnel.

    LOL!  that was a deep dig to find that quote!

     

    hmm... never had an issue bleeding slave on 245 with it in place.  why is it nearly impossible?  and why would you remove it?

    help on trailer hitch

    in BMW 2002 and other '02

    for square tail cars, there is another option for a trailer hitch.  repurpose the center bumper shock mount.  weld a plate and mount for hitch ball to end of it.  hangs right below bumper and could be made so it does not stick out to grab shins.  I used this concept for a towing eye on my track car.  see page 48  in build thread.

    Depends upon how long the straight is on the track you are driving on at that speed. 

     

    It isn't about aero, it is about the suspension.  I could get to 125+ before T1 brake zone at Summit Point in my 02.  No real aero aids.  Rock solid.

    How to bend strut tubes for more camber

    I know you want to be right, especially since you get your information from the internet, but gather a thousand passenger car owners and ask them all, "Raise your hand if you have coil overs". Unless they are enthusiasts that have added aftermarket coil overs to their cars, you will get zero hands raised. Case closed.

    hilariously bad analogy.  you could ask those same passenger car owners anything about their cars besides "where do i plug my phone in?"  and you will get the same blank stares.....  case wide open.

     

    so you are saying if enough people say something that is wrong, that makes it right?  

     

    kinda like using the abbreviation FLCA or LCA in reference to an E30.  there is no Rear control arm.  there is no Upper control arm  there is just a control arm.   it is a CA.  the "F" and "L" are not correct.

     

    or.....calling a 2002 an E10  (rim shot....)

    🙂🤣

     

    back back on topic.....replace the bent strut or buy suspension parts with a smaller diameter spring so the top of the strut can move closer to the strut tower.

    Maybe it’s just me, but I have to press Activity, then all Activity to see stuff.  Prior to the recent change, I simply pressed one thing after logging in. See highlighted screen shot.  Yes, there are the row of icons on the bottom with words, but you have to look there.

    instead of relying on buttons or menu choices each time, go to the page you want, then save it in your browser as a favorite.  that is what I do.  the "unread content" page is my default FAQ page.  when i go to my FAQ page bookmark, first thing i get is all the new content on the site.

     

    PS - i don't bother with the mobile app.  the smart phone browser works just fine.

    Recommended motor oil

    in BMW 2002 and other '02

    Posted

    LOL....it has been a while since there was a "what is the best oil" thread.

     

    and the answer is, like every other time this comes up, there isn't one.  everyone has anecdotal experiences which point to the one they use....and they are all different.

     

    the manual calls for specific grades and viscosities for different usages.    use that.   does not matter dino or synth.  or what brand.   just change it regularly and it will all be fine.

    Engine Hoists

    2ton HF FTW.

     

    And please do not leave an engine hanging on the lift.   The hydraulic rams can fail.   Slowly or suddenly causing the engine to drop.   Very dangerous if you are working on it or nearby.  Have seen this happen. 

     

    Buy an engine stand. 

     

    You don't work on a car with just a jack under it right?  Why would you trust the same technology with an engine hanging on it?

    Diff ratio for a close-ratio transmission

    in BMW 2002 and other '02

    Posted · Edited by M3M3M3

    Since it is for a track car,  the ratio should be defined by what track you drive on most.   You want to be close to redline at the end of the fastest straight.    Then adjust if that puts a shift in a bad place somewhere on track.   

     

    There is no right answer.  It depends on what track. 

     

    Eg... a 4.41 diff was the best ratio behind an s14 and a 245 at summit point.  Over 125 top speed and kept the engine away from the bad ratio gap between 2 and 3 in the 245.  The zf you are considering has an even worse gap between 2&3.  1st and 2cnd gears are useless on track.    Maximize use of 3/4/5.

     

    Rpm at 80mph irrelevant.  Its a track car.   

     

    Tire Pressure: 185 70 x 13

    as you can see there is no right answer.

     

    the tires will be fine over a wide range of pressures.  and will not wear badly in that range.  anything in  27-38psi will be fine.

     

    however...it depends on how you want the car to drive.  want soft , heavy and compliant?  27psi.  want crisp handling and lighter steering? 38psi.

     

    set it where you like it.
