Shelby Alcoa's offsets for upgrading from stock brakes
So, I put alcoa's on my GT some years ago (its a 2006). I am looking to upgrade the stock brakes and want to make sure that the new caliper will have enough space to not interfere with either my +24 mm offset shelby razors, nor my Alcoa's.
My problem is that I've had my Alcoa's so long, I dont remember the offsets. I have 20X10 wheels on the rears, and 20X9's on the front. At the moment, the wheels are up on a tire wall rack, but before I go grabbing one of each down, I was curious if there actually is any markings on the wheels saying the offsets, or if they were sold with only one offset, and if so, what is it?
Anyone know? I'm looking into wilwood as my likely choice, but would like to get my order right the first time and avoid problems with the clearance.
I'd appreciate the help. Thank you
