Suspension - where to start?
This weekend I went to my first autocross of the season in my mostly stock 128i - most notably I'm on OEM non-sport suspension. I've had some suspension mods in mind for awhile but am now looking seriously at going forward with some of them to improve the handling and autocross times. This isn't a track focused car but I definitely want to take it to autocross and HPDEs. Which one of these should I attack first, or would give me the biggest bang for my buck?
Current mods:
Thanks in advance! |

Bilstein B12 struts and Eibach lowering springs is a good start. I would also do Dinan upper camber plates too. Replace the rear shock mounts "while you are in there" they will be whipped. Also replacing the sway bar dog bones(or links) is also a good idea. Upgrading the suspension is going down a rabbit hole.
I would also say having some sticky rubber is a good thing too. Then do the M3 control arms front and rear and new HD tie rods. And then sway bars. Also don't forget to replace the rear suspension bushings to the M3 ones. That really firms up the ride and transitions - when changing direction mid corner. Wheel spacers(5mm to 10mm's) are also good for looks and a slight performance upgrade. You are probably gonna want to upgrade your brake rotors and pads too. And brake fluid.

Read the autocross rule book before modifying. Figure out where you want to run the car... if you want to stay in street class, you are limited in what you can do.
Wheels, tires, struts/springs are going to be your biggest gains. Bushings will help but again read the rules. |
