Hey guys, dunno if anyone opened this thread, but I did not find any.

I am currently on stock rims and OEM Sized winters on my car. But summer is almost here and I would like to explore some options. The OEM wheels are way too tucked in for my taste. I would like to get some aftermarket rims with some lower offsets to push the wheel out a little. Preferably stick to OEM Tire Size in the process.

Does anyone know the OEM Wheel Specs?

I think they are 8.5" F and 9.5" R. No idea what the offset would be like but for the 2021 IS350 it was +45ET F and +60ET R.

Looking forward to get this thread going a bit. I was thinking of doing the Titan 7 TD-6 for these car. Keep them 19" to retain ride comfort though.

 

We have the same specs as the IS350

19x8.5 +45
19x9.5 +60

So all fitments for the 300/350 will do. We got plenty options in 19"

 

On the Grecian Water IS 500 fitted with BBS CC-R the specs are:
20x9 +32
20X10.5 +45

Lowered on either RSR springs or coils

I have also seen similar 20"fitment work:
20x9 +35
20x10 +40

19":
19 x8.5 +32
19x10 +45

There are online wheel fitment calculators available online which help with visualizing fitment.
OEM:
F: 19 x 8.5 +45
R: 19 x 9.5 +60

 

Anyone have an idea of the widest tire we can fit on the front and rear? Assume stock ride height.

And will 18-inch wheels fit over the brakes?

 

Some 18s certainly fit.

 

18s do fit as long as the offset and spoke design clear the caliper, same stuff as with a 19 or 20.

 

Hi all, this may be a silly question - but does anyone know if the 19in OEM F sport wheels will fit the IS500? They have the same dimensions 19x8.5 et 45 and 19x9.5 et 60. My concern is if the calipers will clear. Thanks in advance for any help.

 

Yeah I'm pretty sure there is a poster here who has these on his white 500. So they do fit.

Another question though does anyone know the weight of the Enkei wheels? The BBS wheels?

 

@wthrman2 has them on his!!!

 

Yep, they fit perfectly...




if you dont like the chrome finish, try and order them from Canada, they are painted instead and less prone to show scratch etc

 

Any idea if 18x9.5 et 40 will fit the front?

Looking to do a square setup.

 

Anyone have thoughts on the 18 x 9.5 et 40? They are the Titan7 T-CS5 or T-S5, so I assume they will clear the brakes. Main concern is rubbing on the fronts.

Need to figure this out because I need new tires (14k miles).

 

From the searching I've done, +40 will probably not clear the upright in the front but I'll depend on the specific wheel. Sounds like +38 is generally safe. But a 265 up front with that offset also probably won't fit without a lot of rubbing unless you add a decent amount of camber. I'm also currently trying to figure this out and will be ordering some spacers to test fitment of some different offset options. I'll post pics when I do.

 

I found a set of 18"s that fit well, it was tricky to find a set to clear the front calipers.

My winter setup is:
Konig Hypergram 18"x8.5" +35mm front, +45mm rear
Michelin X-Ice Snow 235/45R18 front, 255/45R18 rear

The +45mm offsets do not clear the front calipers, but the +35mm leave a few mm to spare.

 

Question -- would this wheel set of a 2019 (pre-facelift) F sport still work no problems? Or not because our cars have lugbolts?
