I have H&R spacers all four on my 18 sport and planning on putting some rims. They are 20mm and to make them work with sport stock wheels i had to cut the studs about 5mm. Im planning on putting a set of 20s without the spacers but im not sure if its still safe to mount it with less thread. Im on tein coilovers with one finger gap. If i leave the spacers on what width and offset i can go for?
