To the Malibu: First i have to optimize the Suspension. At the Moment i have BRM Springs and Hijackers at the Rear. The Hijacker System is dead, and the Springs are not make for a G Body Wagon. I think i go with Moog 5660 in the front and Cargo Coil 507 Springs in the rear. All around with Bilstein Shocks. I live in the Mountain with a Million of curves on the street . So the car has to handle good around the Corners. I also load the Station wagon often, so i Need a "stiff" Suspension at the rear.
Maybe i optimize the front geometry with taller ball Joints and/ or modified upper control arms. But I don not know, what the best solution is for me, regarding to Price- Performance Ratio.
Next year i will Change the engine to a 350 Vortec and install a 4 Speed Transmission
That is planned for the Moment. i'm sure there will come many different things additional ;-)
