WRX/Porsche Karmann cabrio 1303

The shock mount on the steel arm is definitely better for higher loads being double shear. No real weight difference. I wanted the narrowest track possible. IIRC there are 2 or 3 different aluminium arm types/widths, the only reason I'd go Al is if I wanted a wider track which avoids use of spacers and gives less axle angles as they are longer.
