Hi guys, new the forum!

was looking to drop my vehicle and wanting to stay with the 19s because I want to avoid using spacers.

would this set up work?

19×9.0 +35mm / 19×10.0 +35mm 5×114.3

I see that its a 35mm offset all around. How would this look in the front and rear if I were to drop my RCF on coilovers?

Depends on tires but it's a very conservative setup. Double check with the company who makes the wheel because some of the multi-piece 19in wheels won't fit the RC-F because of how big the calipers are.*

Could you help me understand offsets a little better? Would a +35 offset poke out further than a +50 offset?

I've seen a picture floating around of an RCF on velgen wheels with a +20 offset up front and +25 rear.

if I were to run a +25 up front and +35 in the rear, would I sit flush or would I still need to use spacers? Finding a wheel with the correct offsets is hard

I don't think you would need spacers with 20" wheels?

I believe that RC-F was running 20s no?

Stock sizes are 19x9 +50 and 19x10 +41. You can do the calculations as the lower the offset, the more poke you get (if getting wider wheels, each inch will be 25.4mm). From personal experience, I usually tell people to run a higher offset up front to compensate for turn radius and such things when lowering your car - with the rears you have less to worry about. Higher offsets in front because I used to be super low with aggressive fitment and it tore through my fenders and I was lacking a fair amount of turn radius. There's also natural camber when you lower the car so that'll help you fit wheels.

The only time you'll NEED spacers is if the face of the wheel doesn't have clearance against the brakes (more common with flat faced step lip wheels) or your tire rubs against the strut - otherwise spacers are just a temporary solution for proper fitting wheels. The diameter of the wheel just has to clear the BBK and usually has nothing to do with spacers.

No I'm running the stock 19s and want to stay with 19s because from what I read they offer better performance, just want a different wheel because as you said, once I lower the stock wheels will tuck in.

would 19x9 +35 in the front and 19x10 +25 in the rear fit flush or nearly flush with each other and the fender?

I'm assuming they would, since the stock offsets are basically 10 millimeters difference from each other, once lowered wouldn't they be the same as a +35 in the front and +25 in the rear?


what was the offset you were using when your wheels rubbed?

Theoretically, it should fit fine but not sure if there will be caliper clearance issues...you could try running a spacer. Only one way to find out

Yes, you will need TPMS sensors to utilize the in-car monitoring and not have errors.

Fronts will look OK, if they clear the brakes. - The outer edge will be will be a bit over ¼" out from stock.

Rears will look same as stock - The outer edge will be in almost the exact same position as stock.
