Looking for some help on this. Will I have any rubbing/fitment issues running RC 350 Fsport 19' Rims on my 2014 IS350 RWD Fsport?
Wheels are 19x8 and 19x9. Factory tires are 235/40R19 and 265/35R19. I know the Bolt Pattern will carry over, but have no clue on the Offsets and if they'll translate.
I've done a lot of research and couldn't find a definite answer.
will the rear have any inside clearance issues? due to the rear wheels being wider AND higher offset, the rear wheel will be 22.7mm closer to any suspension components.

our cars can handle up to 10.5 (maybe even 11) inches wide in the back with the proper offsets
I'm doing this very upgrade right now. I purchased a set of 2015 RC350 F Sport 19" wheels for a great price on eBay - less than 100 miles on them. I got them yesterday and they are pristine!
I'm not going to use the factory RC350 tire sizes, however - I ordered Michelin Pilot Super Sports in 225/35R19 for the front, and 265/30R19 for the rear. This combination produces a tire diameter 0.1" larger in the front, and 0.3" larger in the rear. Speedometer error is less than 1% (59.45 mph at 60).
The front inset and poke change is negligible, but the rear inset is 16.4 mm closer to the struts - shouldn't be a problem. I purchased a set of 20mm spacers for the rear just in case - I'll try them with and without the spacers to see which I like better - they should look more flush. I'm stock height so keeping the same tire diameter, I'm not expecting any rubbing issues whatsoever.
Using the stock RC350 tires would have made only 0.6" less gap, so at stock height these would have probably worked okay, but I didn't want to deal with the speedometer error.
My upgrade to 2015 RC350 F Sport 19" wheels is done! I must say I'm *very* happy with the final results.
I'm at stock height with no spacers, but with smaller tires to match stock wheel diameter for a speedometer error less than 1%. No fitment problems at all - front inset and poke are almost identical - rear inset about 16mm closer in, but no issues there. I put in all new TPMS sensors so I can offer my stock 18" wheels/tires all ready to go - they would be a nice upgrade to a base IS250 or IS350 for sure.
The wheels came with satin silver center caps instead of the normal black ones - I think I like these better than the black ones.
Tires: Michelin Pilot Super Sport. Front: 225 35 19, Rear: 265 30 19
