My rear pads and discs need changing and I was contemplating getting some spiroslots from GT. Thing is, I only have standard pads and discs on the front (for the time being, anyway). Can't afford to both sets this month and rear's need doing for impending MOT. I was just wondering what people think/recommend about OEM front/upgraded rear brake pads and discs. I know if I get spiroslots on the rear, I'll end up getting the for the front too after the summer.
