I’ve used PCCBs and iron rotors on the same car/same day at Mid-Ohio. I found no appreciable difference. However, PCCBs do result in cleaner wheels. A pro may well be a different story. Just my 2 cents which will stay in my pocket.🤣

Everyone has their cutoff. I’ve always had iron brakes on my GT cars because I track them.

My SRS won’t be tracked regularly and it’s all about being lightweight, so PCCBs on my incoming SRS.

But I couldn’t stomach mag wheels particularly as my ADM is a percentage of total cost of the car, and I can always get some later aftermarket if I choose to.

You did the right thing. The mag wheels don't fit the 4RS. All mag wheels will eventually get scratched up due to lack of clearance.
