I've fitted some new bits to my 1200 ute b122

I fitted up Maddat 22mm castor rods
120y swaybar and a set of techno toy rca spacers ..... After doing all this I fitted the wheels and the steering arms are hitting the rims !!

My front end set up is standard 120y struts no camber tops with lowered king springs and s13 front calipers and rotors.... Body is empty no motor

Has anyone had this problem before ?

Wheel size? Putting steering arms on above or below spacer?

14x6 inch rims and putting the steering arms below spacer ... The calipers are close to the arm aswell but still has around 5mm gap !

Sounds like your wheels are wrong offset. A 5 mm or 10 mm spacer should do it (but not legal in some states).

I've only seen RCA designed to go between the steering arm and the strut:

Yea that's how my set up is ..... I might have to try the spacers but first ask the engineer !! And hopefully they don't push the wheels out to far from the guards !! Do you think I need the RCA if I'm lowering the front by 25mm ?

Also could I change the steering arms ? I assume it still has the standard ones ...

That's a pretty normal problem after fitting RCAs.
They're not needed for 25mm lowering.
