Question:
I am not sure if my wheel is 17”inch 501 or 510.
Answer:
It looks like you have the LA Wheel Cosmos Spoke 499 - 17". 
The best we can tell, your wheels will not clear the sport brakes. It is "possible" that you can use spacers to fit these wheels, but we have no way to know if this will work, and what size to use.
Our recommendation is to get one of the wheels listed in the description.

Question:
I have a 2014 Mini Cooper S Hardtop. Im also upgrading my rims with Oz Racing Veloce GT. Do You think this will fit without spacers? Thank You so much
Answer:
We have not tested this brake kit with those specific wheels, only the wheels we have listed in the product description.  If the wheels you are upgrading are 17+" they should fit around the caliper but depending on backspacing and the spoke design they may require spacers.

Question:
Hi! Hope everyone at Mini Minia is doing well! I'd just like to ask - would this kit fit a LCI F54 Clubman S? It's the 2020 model. I'm trying to locate a set of JCW brakes for my vehicle and really appreciate the help. Thank you. Best Regards,
Answer:
The G3NMB2420 will not fit your LCI F54 Clubman S, however there is another kit that will fit the F54 LCI here.

While the factory JCW front rotors 360 x 30 mm, this kit is 335 x 30 mm and the factory JCW rear rotors are 330 x 20 mm, this kit is 300 x 20 mm.

But, this is the factory 'retrofit' JCW sports brakes for your F54. It also includes an uprated brake servo and some other additional parts.
