I've got 288MM discs on my Astra at the moment but am unimpressed with their peformance so i'm thinking of getting the 308MM conversion kit from Courtneys.
Has anyone had an experience with this kit? What's the difference in peformance compared from the 288 discs? Is it worth the money or is the difference not substantial enough? Also, how easy were they to fit? They kit looks pretty DIY friendly.
