One of my first mods, when I get round to it will be to sharpen up the steering on my oil tanker spec car ;) . I have heard that the E36 rack is a replacement. Is this a direct replacement and if so from which car specifically? Are there different specs, what should I look for and what should I avoid?

Try here mate.

Article on it.

I never did it to mine, but from what I've heard it's a good conversion.

Try searching for e36 AND rack for more ideas!

I think an M-Tec 2 steering wheel also assists with feel. I had one on my M3 :thumb:

like this:

I totally agree with Andy.

Make sure you get the smaller Tech II wheel though, the E34 one also fits and is 'boat sized'.

The one Andy shows a picture of is the ultra-rare suede Tech II.... :loser:

Yeah it's worth putting E46 Cabriolet rear shock top mounts on too, they'll probably be fu**ed unless they've been done, the E46 ones are a bit stronger apparently.

Looks nice Andy, I had those seats in my Touring. :thumb:

Make sure it's the smaller one!

Having a bigger one makes alot of difference. It being worse in this case. :whistle:

are they all a straight fit?

They are indeed.

E34 and E30 are the same. E36 is different. You can spot them because they are slightly curvier a la Kelly Brook.

E34 one is big though, try to avoid. :thumb:

One tip though. Don't try to fit it with the steering lock on, it does not work :shame: :shame:

There was me thinking I was the only one. I fu*ked my steering lock trying to yank the wheel off. :(

yeah apparently the e36 rack is a fairly simple swap, but it can cause clearance issues with any manifolds fitted....

aparently , according to "Pookey" on e36coupe.com

As there has been a lot of hearsay going around about the various steering rack ratios fitted to the E36 and the M3s I have spent some time doing some measurements (and have used some of M3 Compact's measurements) plus confirmed the data direct with ZF (I know someone who works there who can access drawings on their system).

The standard way ZF quote on-centre (straight ahead) ratio is in mm/rev, which is the travel in mm of the rack bar per revolution of the hand wheel. The higher the mm/rev the faster the rack.

M3 3.0 - 39 mm/rev- the slowest available rack. This is a variable ratio but it is slower than standard until 200 deg hand wheel angle

M3 3.2 and standard E36 - 45.5 mm/rev- the M3 3.2 rack has restricted lock.

Z3 rack - 53.5 mm/rev- by far the quickest rack you can fit.

E46 compact rack - 50 mm/rev- apparently this also fits the E36

Because the M3 3.0 has a variable rack it has the smallest lock to lock at 3.0 turns but donít be fooled it is the slowest by a country mile. A worthwhile upgrade for any 3.0 M3 would be to fit a standard E36 rack which is what I did a year ago with a noticeable improvement.
