it was for me as i needed new discs and pads so therefore it was worth spending that little bit extra. it depends if you intend using the car on track. If so then I'd go for something beefier, but for everyday normal and spirited driving they are good. Tis only my opinion though
Very easy to swap over - I paid my mechanic £20 to do the job for me
if you have the cars listed it's literally just swapping the discs and carriers over so in theory its very easy!
