hi i was wondering if there is a era of 120y/coupe disc brake struts i should be getting or are they all the same?
and will this combo change track?

The pbr style struts I think. And, you need the kev Rowley adaptors too.

Won't increase track as much as stanza conversion

is there a way i can tell if they are pbr struts? and are the adaptors for the caliper mounts?

Also depends on ball joints use bj176 if you want smattering track

Track increases only if you use the Stanza balljoint

i would rather less track if i can. my rims sit outside the guards already.
so what do i need to look for in struts?? i can engineer a caliper mount

Depends on engineer

you can use 1200 disc struts or 120y disc struts. the later model 120y struts (that came with pbr calipers) are the better
ones as they have a larger stub axle.

your track will increase by approx 7mm per side (the thickness of the disc mounting face) because the rotors slide
over the hubs. you will need custom caliper bracket and to machine your hubs to accept the s13 rotor

thanks fellas. does anyone have any to get rid of?
