Good luck with your plans. I have been down the route you are heading with regard to modifications on a MK2 Leon Cupra (and a lot more on top) and you can end up with a proper quick car with the correct parts. One piece of advice I would give however is not to swallow every single mod that is commonly thrown up as some of them are a complete waste of money in my opinon.
I wouldn't pay that much for a Cupra 'R'!
Had stage 1 Revo on my Cupra for a while now (Been really happy with it), was gonna sell it on but circumstances have changed and now looking to up the horses. Please do let on as to your experience of getting a proper quick car, with the correct parts and what mods are a waste of money?!
Was thinking of full tbe - Milly or blueflame?
Do i need a CAI - ITG or Evoms
HPFP - ?
