right my rear shock on the mk4 is gone

so thinking jus fookin it and buying a coilover kit instead replacing just the one shock..after a year iv finally decided do it.. maybe thats why my shock went its a sign!

I wana spend £180 max on coilovers.. so thinking getting JOM ones from venom motorsport sport.. what you guys think??
