sorry about taking so long to reply mate! been swamped with endless **** this month 
if you haven't done it already the cupra r splitter is easy fit with the right tools, gonna need to trim the edges of a little, slide under your car, measure up the holes, i used a 5mm drill bit and put id say about 6/8 holes in the bottom of my bumper then used 6mm screws to make sure it was a tight fit.....month or so down the line it hasnt moved since!
springs finally arrived as well boys, fitted rear springs yesterday, not a dramatic change but noticeable. hoping with the front in it'll look better, but handling has improved incredibly!
