Hello friends,

As part of my e46 M3 Project I'm contemplating replacing my steering rack with something a bit quicker. It's a known fact that the e46 has a not so quick rack, and even my 20d has a faster steering.

With that said, I would like to keep things as OEM as possible, hence I'm thinking about installing a CSL rack on my peasant M3. However, I have no idea of what difference the smaller ratio (15.4 vs 14.5 to 1) will turnout in steering wheel turns.

Can a CSL owner (or someone with a CSL rack) do a short video of the steering going from center to full lock?

That would be great for me.

Thank you so much in advance

Hey mate. I know about the purple tag rack. The reason why I'm avoiding it is because I think, since it's fitted to a non-M BMW, it probably doesn't have as much feel. This is purely based on judgment and not research.

There is a bit of confusion going around... Also some people say that when you replace steering racks you have to do something to the DSC because of the steering angle, and that's not true.

Just trying to get the most accurate information possible

The CS and the CSL run the same rack, maybe that can help you broaden the search.

That's well thought. Didn't remember to do that.

Perhaps post this thread on the normal M section?

I think on the earlier dsc units it can play up but if it's a mk60 dsc unit it would be fine , I've been considering one when I get the engine back in.

I haven't read anything about the version of the doc unit. My car is an 02, with DSC still on the engine bay, where the battery would normally sit. Would there be a straight forward way of knowing which unit I have?

My 53 plate M3 was fitted with a CSL rack, one of the best mods for these cars.

Why don’t you count the number of turns lock to lock that you have now, then use the different rack ratios to work out how many turns there will be with the faster rack? I.e. Multiply by 14.5 divided by 15.4.

I've driven a CS M3, which has the same rack as the CSL and there isn't much in it to be honest. You need to turn a little bit less, that's it.

I had already seen a video, that a member sent me, and compared it to my M3 and decided that it wasn't worth it.
