I can highly recommend Eibach springs, they are great. Mine are -30 to 40mm which is a very good drop, low without being impractical. I wouldn't lower 60mm where I live cause the roads are very bumpy and lots of speedbumps - it'd be a nightmare.
Best to get new shocks too, Koni ones are awesome. But I don't think you'd get this setup for under £220, unless you can find a second hand one.
I could also recommend my koni -30 to 40mm springs, which are in the for sale section. Make me an offer hahaha!
