Comprehensive Steering Information Thread

Not enough to not trip up DSC. It's very mild difference - M to non M (pivot point to steering tie rod leverage point. About 5-10% IIRC)

Does the coupe have the M3 or non-m e46 steering ratio in the knuckles? M3 slower might be better in this case.

From the data on this thread, the M coupe has the same knuckle ratio. The distance between the CA ball joint to the tie rod is 130mm on both.

Yeah I’m confused as most literature seems to have the m coupe at 13.7:1 (same as non-m ratio with 150mm/rotation rack) which is 126mm ball joint to tie rod from my scans. M3 is 130 as you’ve posted above. About 3% quicker on center

I just bought the black tag for my coupe. It will be interesting to see how it fares for road use with a more normal stocking wheel & tire setup

Did your original rack have a problem, or you just wanted something quicker? I noticed my roadster has a silver tag rack vs green on the coupe, which I guess they all do? All the pics of the part number 32137836844 have a silver tag.

Hi Chris, nothing wrong with my rack at 53k miles, I just want the quicker rack. The MCoupe is not bad, but I have a Tesla Model 3 which has much faster steering and I find it better for my liking, the M requires way more lock in the winding roads I go to.

people say it can get twitchy, but I don’t buy it. I used to race karts with 1:1 ratio.
