Will 18x9.5+30 square fit i am currently on stock suspension?? I do plan on lowering in a couple months will the rsr superdowns work?

 

The wheels are going to stick out with those offsets. If you install the Superdowns there will definitely be issues.

 

So what about 19x 8.5 + 30 front and rear 19x8.5 + 25 will this ones work?

 

I'm not sure why you want to use the same size rims, but with different offsets...i don't think anyone has done that before.
If you plan on doing Superdowns later, you'll want to make sure you have enough offset so the top of the wheel will tuck in under the fender when the suspension compresses.
You should be okay with a 19x8.5 +30 square setup with a 225/35/19 tire.
If you are able to get a 19x8.5 +35 square setup, then you could run a 235/35/19 without clearance issues.

You can have a look at the wheels thread to see a wide variety of styles, sizes, fitments, etc.: https://www.clublexus.com/forums/is-...exclusive.html

 

I have 18x8.5 +30 and I rub when the suspension fully compresses, mainly if I hit a good size dip when I'm going too fast.

I have stock suspension.

 

Great feedback.
What size/brand of tires are you using?
I'm assuming the rubbing is in the rear.

 

Stock size tires. I honestly can't tell if it's only the rear or both. It happens very rarely, sometimes when I expect it to rub, it doesn't. Just depends on how fast I'm going and how deep the dip is.

Just to be clear, I'm talking about dips in the road like where a new patch of asphalt meets an old patch.

 

So you're running a 225/40 18 on the front and 255/35/18 on the rear? Those are stock F Sport tire sizes.
If you have 18x8.5 square setup, then the front tire would be stretched, so I doubt the front is rubbing.
I'm guessing the tires are maybe Michelins...that have wide Tread Widths and square sidewalls.

 

Guys i know this is a lil off topic but can i save this tires jus bought them like 7months ago they are michelins sport 4s but the inner thread has lots of wear the rest is fine please help if i need new tires

 

Those tires are done! Like beyond done!
Once the cord is showing it's now a safety issue.

 

I’m guessing it’s the tires as well if it’s the rear. I have the same size rims (50 stock rim offset with a 20mm spacer which equals to 30) and tires with stock suspension. No rubs at all with Bridgestone Potenzas.

 

Some have reported rubbing in the rear with 20mm spacers.
Usually it seems people install 20mm in the front and 15mm in the rear...which would put you at 18x8.5 +35 in the rear...which would be fine.

 

Yup, I have seen those who are rubbing at rear with 20mm at the rear. Turns out fine for me due to the slimmer side wall of the Bridgestones...I guess I wouldn't consider myself stock height though, somehow my car lowered itself on stock suspension for about an inch after the spacers are installed(25mm front and 20mm rear). My wheels are now flush with the fender and each of them has a 2 fingers gap.
