The complete strut assembly and brakes from a Nissan 280zx are a common and easy upgrade for 510s. The entire assembly will bolt in with minor modifications.
a: Replace the 280zx spring perches with the 510 spring perches and upper hat.
b: Install camber plates and lower collar for adjustable coilovers I.E. Ground control coilovers
This will provide several things:
- Larger vented rotors
- Calipers with larger pad surface
- Larger wheel bearings
- 1/2" narrower track for more aggressive wheel sizes
