I have started on the control arms, just measured everything and thinking about what I need. Basically I want each arm to be adjustable and I want to remove all rubber bushings so all the joints are either rod ends or spherical bearings. I will modify some of the factory arms and possibly build some from scratch. I may buy some toe arms straight off the shelf.
In other news I was doing a bit of work on my WRX this weekend as I want to resume racing it next year after taking this year off. After my last race I took all the brake system apart, deleted the booster and ABS. Installed a dual master cylinder and balance bar with hydraulic handbrake.
I also removed the airbags and air conditioning which left a big mess of wires where my center console used to be, the car now weighs around 1210kg (2660 lbs).
So today I made a small panel to house my engine oil temp gauge, water temp gauge, intercooler waterspray switch and adjustment dial for the balance bar which changes the brake bias. I also added a phone mount.
