    Yay for doing things on the e30

    Yay indeed.  This is one of two things i need to fix at a minimum before i track it.  The other being, why does my tank leak fuel when more than half full, or when i corner hard right...  I've decided that i will have to commit seppuku if i dont track this car this year.

        Genius.  This would allow me to use the current cable like so?

        yup, exactly what i pictured.  be careful on those adapters, though, they may have a different post size which your cable wont clamp to.

          I think i'll try this combo.  JIS post looks small and tapered, but they make shims to adapt to SAE post.

            That is very kind of you.  That would be an epic death.

              looks like that should work!

                This thread confuses me. Why do you need to change the end on the stock battery cable? 
                Or is it not stock.

                  to me, it looks like someone in the past modified the end of the original cable, either because it was damaged/corroded or they used the wrong type of battery.

                    Is this the picture of what is actually on your car?

                    If so I hate previous owners of that vehicle

                      Yes, the end on the cable is NOT stock, which is the source of all my issues.

                      Using the SAE to JIS adapter, i'm able to make a stock size battery fit.  I couldn't orient the adapter the way i wanted, but this orientation doesn't put the cable under much strain.  And now it's held down with the OEM clamp.  It's better now.  Hopefully good enough for a tech inspector.

                        Stuff a 20 under the cable pre-inspection and you will be fine

                          If just a tech inspection for autox or a track day as long as the battery doesn't move with the stock clamp setup when the inspector checks it you'll be fine. I ran mine the same way for years.

                              if you aren't completely happy, those post extenders i original shared are like $5 at advanced auto parts, saw them when I stopped in the other day.
