I've just purchased BDR RT2 #358, the car is great, handles well but I have issues with parking it. My garage is very tight and I've recently injured my shoulder so getting it in is kind of PIA with the current steering rack.
So I'm thinking to upgrade it to power steering that can be turned on and off. I want to keep the same feel while driving the car.
I've tried to find kits online but it seems nobody offers anything for RT2, so I need some help to point me in the right direction.
I've read somewhere that BMW Z3's power steering rack is compatible with my car, they are pretty cheap to get here in Europe.
Any tips are appreciated.
Thanks
