Bare with me here, this makes sense in my head. I wasn't sure if this is a suspension or a brake question, but I'm starting here. lol
On my wagon, Eileen, I still have the 325 trailing arms but have swapped to 330 brakes. The downside to this is I do not have a functional parking brake at the moment. My goal in this project is 2 fold:
- I want to have a parking brake.
- I want to swap everything to M3 brakes (front and rear, booster, ABS, etc) as well as the complete front suspension.
The reason for keeping the non-m diff is that I have a 4.44 out of an X3 in the car with a Wavetrac, to get something comparable in the 210 diff would be a $3-4000k minimum adventure. I would rather spend that money on a BBK for the car.
SO my question is can I put M3 trailing arms on the car and keep the 325 subframe and diff. I would use 330 cv shafts (and obviously flanges on the diff).
This is why I think it is possible:
- The upper and lower control arms are the same for both cars.
- The 330 and M3 CV shafts use the same axle nut and it appears the splines are the same od.
- The 330 and M3 have the same rear track width.
You would think I would know the answer to this but I do not and searching is surprisingly difficult consider all the threads about putting M3 brakes on these cars (usually complete subframes). I have all of these parts but they are assembled in various systems and cars and it would require disassembly. Does anyone know?
Thanks, George
