ok basically for months my car has been shaking with no clue to what is causing it but on the weekend it got worse and found out it was my driveshafts, but fortunatly my mates breaking his paseo st, so yesterday i come to swap my driveshaft and it fitted perfectly in the gearbox using his cup! but it didnt fit my hub so im gonna swap all his hubs discs and callipers now am i right in saying they are the gt spec ones as there bigger than mine his are 255mm compared to my 238mm ones now will this just be a straight swap or is there complications? also will my brake lines bolt straight into his callipers as they look the same? any info welcome also will i see a difference in breaking cuz i have uprated discs and pads currently! thanks Dean
