Spigot rings needed £5 off ebay cant recall offset but they out more than std but so are the .R wheels 19 x 8.5j fill the arches nice imo mines on cooksport springs, the R888 did rub a tiny bit on track due to the straight sidewalls i think
Yes, they'll be catching on your inner discs/ hubs if you don't. My front came loose whilst driving as I'd used shorter bolts but the standard length locking bolt. Not a fun experience.
I recognise this car from FCS a few years ago. How long did you have the RS wheels for ? I could be mistaken....
