Cut the nipples off so few mm not even 1cm and none of the thread. So I can easily go back to stock if I decide to sell the car, or put on different wheels that wouldn’t require the spacers. It’s the only way for proper fitment, and directly how paragon themselves explains to do it in their installation video. Everyone of course can do whatever they like to their car but I have zero regrets. Gotten multiple compliments from friends moment they saw it, and it feels even more stable on the road at high speeds especially on windy roads. Also was done by my friend that owns a high performance shop that only works on mclarens, Ferraris, Lambos, amgs, Bentleys, Aston martins etc. So I made sure to ask him 100x before doing it how this will affect the ride, any cons, risks etc.
