New Guy with a quick question

[Rz3]

Hey guys I've got a quick question I already have a 1998 Z3 2.8 and Im going to be looking for a 318Ti over the next couple months to add to the garage and I was wondering if the Ti has the same rear end problems as the Z3? and If so is it known to be specific to some years and not others?

Sorry I searched rear end problems and couldnt find anything

What problems does the Z3 have with its rear end? Ive never heard of any in either the Z3 or ti

The trunk floor welds come apart due to the way the single ear diff is mounted, so that requires obviously a lot of work to fix and a special reinforcement kit and a dual ear diff cover so it doesnt happen again.

Im gonna go out on a limb and say thats probably only an issue with the 6cyl Z3s, because the Z3 and ti have a near identical rear suspension and thats not a issue on the ti. Granted a lot of people upgrade the rear subframe to handle more power but the trunk floor welds aren't really an issue on these cars.

There are a few cases of this happening on tis but they are usually making more than stock power. No specific years that I can recall.

Bluebimma worked with Randy Forbes to reinforce the floor of his LS swapped ti and Bubela has a turbo M52 ti that he had to reinforce the floor of.

Since you know what to look for it can't hurt to inspect the trunk floor the cars you are considering.

I also had a few spot welds blew out on mine. I also had a Randy Forbes kit put in, I made a thread about it in here if you would like to check it out. Keep in mind this is also a swapped car.

I don't think you'll run into any issues with a stock ti but it you swap the motor it's something you should keep an eye on.

Thank you guys! that will definitely help me decide on what to do because if i went out and bought a ti i would definitely want to swap it and most likely track it.
