I think 30 profile is ok too
I run that on other cars without Much problem
I checked out your BBS wheels last week when RS direct posted pics on FB
id like to know your offset as I believe 45 brings wheels out about 12mm from standard so no spacers needed (providing I guess that they don’t catch)
if you’re on 30mm lower too I’m thinking you’ve answered all the questions that tuners couldn’t by just using the FIT which is what I normally do ?
