The 280ZX strut swap into a B110 is popular in America. What you gain is large, vented rotors that won't overheat while racing. The 280ZX is model years 1979-1982 (Nissan chassis code S30).
For more overview, see main article: Strut swaps.
Features:
- 10" vented rotors
- solid, single-piston caliper
- shorter strut height
- will clear certain 13" wheels. Note that Z-car (240Z, 260Z, 280Z) struts/brakes require 14" wheels
- decrease in track allows wider wheels/tires
Whitesedan is looking into Toyota Hilux 4-piston calipers for this swap. Hilux 4-piston calipers have greater clamping force than the ZX calipers, but are considerably heavier cast iron units. Most say stick with the ZX calipers or upgrade to the MK63 FIA brakes.
B110 strut housing is 45 mm diameter. B210/B310 is 51 mm. What is 280ZX?

Coil Springs & Strut Top
Now the spring of the ZX strut is too large diameter for the B110 strut tower bodywork. So you need do one of the following:
- Use the B110 coil spring (110 mm diameter), spring cup and strut top hat, and fit it to the ZX strut.
Or
- Remove the spring perch and use a weld-on Coilover Springs kit
Also drilling may be necessary for the insert to fit into the strut top. Whitesedan used noltec camber/castor adjustable strut tops.
If using TRD inserts, use the TRD strut top.
Balljoints and Lower Suspension
The spacing where the strut bolts to the steering arm is the same as a A10 (1978-1982 Stanza aka 510), 610 (180B), 810 (Maxima, 200B), etc. This is different from the B110/B210 spacing. So, use A10 or B310 (Sunny, 210) parts:
- lower control arm
- steering arm (knuckle)
- balljoints
- outer tie rod ends
Tension Rods
The B110 and B210 Caster rods (aka tc, radius, tension rods) can be used. The length is correct, but bolt spacing needs to be wider for the A10 balljoint and tapped to M10. This means drilling one new hole in the tension rod.
For more details, see Caster Rods.
Instructions
Use at your own risk.
- Disassemble strut, including removing cartridge or guts
- Cut spring cup off the strut
- Cut length of strut down
- Reweld cup at new lower position
- example
- Fit new, shorter inserts
- re-assemble using stock B110 spring and top hat
Optional:
- Fit quick-ratio 280ZX steering knuckle
