Any tips on what steering wheels/shift knobs/ebrakes from different models work in the E30?
I'd like to replace everything with leather like this.
Lets see, I'm not sure about steering wheel fitment from other BMW models but there will be issues with spline count and column diameter. You would probably be able to make any steering wheel fit with the correct adapter, but I'm not sure how that works.
As for the shift knobs I'm pretty sure any model BMW shift knob will fit any other, I think they all use the pressure fitting with the two notches for alignment.
For the ebrake handle, I can't remember what model the seller said mine was from, but you'll have to research that to be sure anyways. I think the main fitment issue is length since the e30 handle is long and the boot won't meet up with a shorty handle. You could just get whoever makes the custom ebrake boots to customize it for whatever length of handle you end up with.
I definitely prefer the all leather feel. And was really glad to get rid of the accordion ebrake boot. Plus the mtechII wheel makes me happy(er) every time I get in the car.
