I think if they do hang lower I would have to go OEM anyway, barely clear the speed bumps where I live at stock height anyway. Jords I think that might be exactly what he had done, thanks for the comment Ill also keep in mind the other braces if i need to get those sorted. So far Ive had the U bends on my calipers sorted luckily nothing else needed changing on my brake system, Although my pedal is now a lot less sensitive, way more travel before any braking happens im guessing maybe low fluid or trapped air? The parts for the brace should show up tomorrow and ill get them on. I had a leaking balljoint on my front right but thats been sealed and I think im leaking gearbox oil so ill need to get that sealed or at the very least my oil topped up. I think I just assumed the worst when nissan told me to fix everything it would be £3500 in just labour, no parts included.
Thanks for all the comments helped me calm down a bit, turns out im already really attached to my zed, didnt want to see it die a horrible rusty death.
