You cannot use the GSF/RCF dust shields. You can, however, use the RCF Track edition dust shields. However in all honesty - it’s 2 minutes to trim an inch off the shields.

Are the OEM caliper options only orange or blue? Neither is great with Atomic Silver IMO...
They come in black also with Lexus Logo instead of the F. (first year RCF, 2015)
as well as a Candy Redish Orange in the current year RCFs

Silly question…so what is the actual URL to the BBMS site for the brake kit? Google search for BBMS Brakes or similar was useless. thx

Anyone come up with a solution to upgrade our spare to 19” so it will clear the front calipers?
im very close using an RC F from modern spare except for 1 major detail: the lug seat is flat for the RC F lug nut where we need the ball type seat. Ugh… anyone find a workable solution yet?

you have Lexus roadside for the first few years you have your car. Get a AAA membership after that.

Maybe it also fits with a spacer like the Enkei wheels?

You could do a stud conversion on your car and ditch the lug bolts. Keep a set of mag type seat lug nuts in the trunk for your spare, and your 500 wheels obviously will have the ball seat nuts.

Slowly piercing together my BBK. Is $300 a deal I should jump on for a set of used rcf front calipers with 1000 miles? Anything i should look out for a set of user calipers?

For clarity, it's part numbers 47730-0W150 and 47750-0W150 and here's an image pulled from Google.

that's not a bad price for a caliper. there's no way you're getting a set for $300, but if you are, jump on it!

Welp you're right, some scammer on Facebook posing as elvin carbon fiber. Spidey senses were tingling with this one.
