    We can get back to ITB's later - I could use a hand sorting this out:

    Well.... Might have found the culprit for my slight grinding from rear. Not sure:

    Rotated wheel ends from both sides - couldn't hear anything troublesome, only noise was a slight "whine" from diff. So put new pads in passenger side and reassembled - turned over to same results. Put rotor back on drivers side and turned over by hand. "GGRRIIINNDDD"

    Ruh-oh

    Checked to make sure ebrake was fully disengaged, rotated again and got the same sound. Removed rotor and found these on inside of rotor:

    AA5EDD52-B165-40F7-AF57-871A7C033B7B.jpg

    2 separate cracks, about 60 degrees apart. I swapped rotors side-to-side and got same grinding.... So not sure if it's the issue.

    Shoes are seated firmly against backing plate, springs seem to be under good tension, and brake appears to be operating normally. There was some heat cracking on shoes - but not excessive wear.

    Thoughts?

    Don't have a lot of experience replacing shoes/springs, so will have to do some research in the AM.

      New rotors should be the fix=)

        I would agree - except when I swapped rotors the noise stayed the same.... Makes me think something on the shoes needs adjusting or replacing?

          I have a burning hatred of the M20 intake manifold, if I keep that platform it will have to be changed to something (SRI, ITB's, ANYTHING else). I'm open to a lot of ideas... Just not keeping that ugly ass mani.

            does the sound change as you pull up on the handbrake ? 

            My original handbrake shoes had chunks missing from them

              Not while driving.

                  I thought my grinding/noise was a poorly adjusted ebrake shoe until i ran the car on jackstands, put my head under the rear, and heard the sound was coming from the diff.  I have a different diff in the car now, soon i will see if i improved things...

                  I also have a irrationally massive hatred for the stock m20 intake manifold.  I dont care if i mess up any finely tuned Helmholtz resonance that the stock manifold provides, I want it out. It just doesnt look right to me and clutters up what could be a beautifully clean and simple engine bay.  Sign me up for any ITB development prototypes:)  I was also having turbo thoughts just last night to justify a manifold like this

                    That intake manifold is beautiful! Is there any aftermarket companies that them like the one in the picture?

                        I'm LOVING that intake mani above!!!

                        I wonder what the power band would feel like to run a intake mani like that NA, with the intention if running boost in the future? I'm assuming a slight lose of low end torque, but possibly a slight gain at higher end (depending on runner length and size). I'd want internal full bell radius stacks integrated into design....

                          Very easy to do with m20! Especially if you aren't incorporating itbs. But I bet you 50$ that intake manifold won't flow better than stock NA.

                            Stock NA? You're probably right. With some standard bolt-ons tho (cam, chip tuning, bigger injectors, etc...) I wouldn't be as confident.

                              You could make one work for a good NA build before going to a turbo, but it wouldn't be any better than the octopus besides looking better. In that case, I say do it because I am a douche and am all about looks=)

                                I hate the original manifold enough I'd have no issues sacrificing some performance to change the aestethics until I had everything ready for boost. I'd like to pursue the ITB route tho if we can make it cost effective.

                                  A log manifold will have much nicer acoustics/induction sound than the stock M20 manifold. I would do a custom log manifold before ITBs, you will still gain awesome sounds, especially when running MS with a map sensor.

                                    So you believe ITB's with boost wouldn't be really worth it? I could build a regular manifold this weekend... hmmm.

                                      And how long of runners should I build? You should help me design a plenum!

                                        I can swing buying the materials and labor for a good log mani in fall - I don't think ITB's and everything to do it "right" are my budget for this fall. :(

                                        Here's what I would like to see:

                                        -Tapered plenum that clears stock brake booster

                                        -Velocity stacks (preferrably full bell radius that protrude "into" the plenum - but brake booster clearance could be an issue)

                                        The main issue I see is the brake booster - clearing it restricts the runner lengths.
