Suspension issues...MOT, Suspension arms, FK coilies

[Rogeball]

So, passed my MOT, eventually. Once they'd charged me for a new rear door lock. Seems to be one thing after another at the moment.

Anyway, somehow my very dark tint covered lights got through unscathed!

I did however have some advisories on suspension arms and my rear springs being corroded too! Only had FK Street coilies on for about 18 months, so bit annoyed showing up on MOT already!

So what's peoples thoughts and experiences?

Worth getting a good suspension arm kit, if so which one and what to look for?

Also, what to do on springs, get new ones, or get lowering springs and lob the old standard set up on? Don't want to throw loads at it, but only 50k on clock so hoping to get few yrs out of motor at least tbh!
