Nope no holes need to be cut in wing, the pipework will fit through the existing holes already there, it might require a wee trim on the inside of your bumper but its nothing major TBH, A/C can stay as well the FM dosent interfere with it at all, ive just ditched mine though but only cause its a dead weight and never used, Hybrid GTII ones from Harvey on scoobynet are very well priced
Brakes either AP or Brembo seem to be the most popular choice but with the AP name comes a heavy price tag
