Hi All,
I have some doubts if a car was hit / bent in the past ... so I would like to have some dimensions to measure.
I got to this site:
http://cargeometry.com/body-dimensions/ ... 72003.html
but .. honestly .. $20 for this .. and honestly I dont know if they will send all the files ..
Anyone got this ?
Chassis dimesions data
Re: Chassis dimesions data
Personally I'd compare side by side with another Z3. And or by offering up known good parts like the chassis brace to see if they fit. Eg the chassis brace on the car may have been squeezed in by 1-2mm with the chassis rails at the time of an accident so just because it appears to fit... In fact that's exactly how I knew the chassis was damaged once.
If you look on Youtube for Arthur Tussik you will see the tool he uses and how he checks for alignment in a fairly low tech way.

2001 Z3 2.2 Topaz Blue (Trudy) - Keeper rebuilt from a write-off
2002 Z3 2.2 Titan Silver (Cookies) - Keeper rebuilt having been bought with a seized engine
2002 Z3 3.0 Sapphire Black (Peanut) - Keeper awaiting rebuilding having been bought as an abandoned project
Plus Willy, Kodak & Maycee - All 2.2 Sport projects. Yes, 6 is a lot of Z3s
Always happy to try and help with spares

Those files do look interesting for geeks like me though

Re: Chassis dimesions data
Yea.. I will start with the initial idea - to measure diagonals...
so if the two diagonals do not match - the car is bent ...

Re: Chassis dimesions data
Yes that's how Arthur measures. With a big bar across matching diagonals. I think it's called a tram gauge.

Re: Chassis dimesions data
Why don't you simply have a full geometry check at a good tyre dealer? That will show up any problems such as bent trailing arms or rear cross member, not to mention distortion of the front cross member, chassis rails, or wishbone mountings.
A Z3 is not just for Christmas - it's for life!
Re: Chassis dimesions data
Diagonals are fine. The chassis looks good. When measuring the longest diagonal - from front cross member to the big bolt holding rear cross member - the difference is 1-2mm. Which is inside the measuring mistake
I will go to a alignment machine because I have to setup the suspension and we will see the data there.
Thanks for the input!
