Author Topic: Z3 rack question (Read 3635 times)

I know this topic has been beaten to death - but I need a quick definitive reference. I am swapping in a Z3 rack. I don't care about the pros and cons of the various e36 racks - anything is better than the stock beast. I have been through 3 racks on my car and I'm hoping to have better luck with something other than stock - you would think I would have learned after the first two.

All I want to know is, do I need to modify anything to make the Z3 rack work or is it just fiddling around?

The best writeup I've found so far is at:

http://www.e30dohc.com/wiki/index.php?title=E36_Steering_Rack_Swap

Does anyone have any experience with this - I've read elsewhere that it is basically a straight bolt-on. Also, if the steering knuck does have to be modified than what is the exact size of the spacer and where do I get one?

Cheers

You will most likely need to modify the firewall

I haven't done it myself yet but its on the list.
(the procedure is different for airbag cars and nonairbag cars)

No, you won't have to cut the firewall. Its plug and play with a few minor adjustments to the steering column and some washers to the mounting bolts.

No airbag. I wasn't sure about the firewall bit - some say it needs to be beaten back other not. Also, the writeup I cited about shows disassembly of the steering knuckle to add spacers - are you suggesting just adding the spacers where the knuckle mounts to the rack.

Anyway thanks for the advice.

Oh I've never seen a 91 car without an airbag. Nevermind. Different story.

Can I get some links for more details?

The first guy to use washers.

My swap in same thread.

The guy that started the thread said to bend the mounting tabs for the rack in order to fit it. DON'T DO THAT! Just unbolt one of the two engine mounts and jack up the engine by the oil pan about 1" or two. That'll give you enough clearance to install the rack.
Good luck

thanks for the info - seems pretty painless.
