well i finally found a 323 parts car, got the whole car for 80 bucks, good deal huh? anyways my first project will be converting my 320 to the rear disc brakes. are there any writeups out there that cover this? what all will i need to change to make this work? and is it pretty straightforward? also i want t o put in new bushings in the trailing arms, which ones will i need? thanks guys!

Hey, not sure about the rear conversion, I'm still looking to do it myself, But did the car come with euro bumpers? would you be willing to sell them? if so, how much? Thanx.

unbolt old trailing arms, undo the emergency brake cables and the brake lines, unbolt half shafts. Bolt in 323i trailing arms, reattach brake lines, (not sure how the ebrake thing works), reattach half shafts. Never done it, but it seems pretty straight forward. I've also heard that you will need to remove the brake biasing valve near the firewall on the drivers side. This biasing valve makes sure that the drums get less fluid than the calipers. But since you have calipers all around it needs to be removed. do a quick search on google, you're bound to find a 2002 guy who has done it.

you have to change the rear brake lines to the ones from the 323, the ones from the320 won't reach the calipers, but is an easy remove and replace affair. better have an impact gun to make easy work of the trailing arm bolts, and the axles retaining nuts
