Currently I have a stock 2001 GS 300. I'm planning on upgrading the front brakes to LS400 BBK with 30mm RCA. While doing research, some say with RCA, you can fit a 18 inch rims but when I talked to a person in FitmentIndustries, they said that my rims would not fit with the LS400 BBK. Do you guys have the backspace needed to have clearance for the LS400 BBK? Any tips or suggestions?

I was going to get 18x8.5 for the front
DS01 18x8.5 +35 (https://www.aodhanwheels.com/collect...43676163637507)
or
WORK S1 3P 18x8.5 +35 (https://www.fitmentindustries.com/bu...s&setup=Square)

^ Would these rims fit the front brakes?

 

Backspace is irrelevant. Spoke design and hub thickness are what matters.
