So I'm collecting my 172 rep tonight which is sitting on 182 cup alloys, lowered all round, just wondering what spacers are best as the wheels are sitting in the archaic at the moment. I've had a good look about and have so many different answers from just 5mm on back to just 25mm on front to 8mm all round lol! So confused, can someone let me know please just want them to sit more flush to the arch
