Thanks for the advice, I just want the Z to look similar when it had the 18x8.5 Super Advan SAR3 wheels with spacers. I sold those wheels and now I regret it.

that Advan set up is garbage. There's like three feet of wheel gap. You can stick your head in that gap. There's a reason why nobody should run 18's on a Z except for track - it looks like poop

buy real wheels in 19/20
buy coilovers and the SPL setup
take your car to a good alignment shop
enjoy your awesome looking car

New 19" wheels are on the way :)

Currently looking for tires... Suspension setup after that!

I have;
FR 19x9.5 +25 (Work M8R) on 265/40 (Goodyear Eagle F1)

RR 19x10.5 +12 (Work M8R) on 295/35 (Goodyear Eagle F1, 12 inch tread width)

The front tyres rub when I hit bumps or pot holes or even wavy roads.... my car is the Nismo 370Z MY17 so the front fender wheel well trim has an attachment point for the wheel arc garnish that bulges out... this bulge rubs my tyres.

I confirmed it by seeing the "hole" on the bulge's edge created by the tyre rub...

Your tire sizes are off. They are taller than stock. You should have gone 265/35 front and 305/30.

Also, I assume you did not get front camber arms

Lastly, take those ******* nismo fender flares off, they hurt clearance

Option Zero VS Fender Flares 4 life

I got the same rim specs as you in the front. I have 285/30-19 with no rubbing.

FWIW, I am also running 265/35 fronts on the factory Nismo wheels, no rubbing at all. I did notice a big improvement in turn-in and front end responsiveness over the stock 245/40's. Only drawback that I can see is that the car "tracks/tramlines" more when driving on roads with tire grooves from heavy trucks. (2010 Nismo, no suspension mods)

your nismo doesn't have those damned clip ons

295/45zr 18 in rear-Speedometer issues
 

I put 275/40zr 18 in the front and 295/45zr 18 in the rear of my 2012 Z. After install the speedometer stopped working and dash lights are all on, ABS, traction control; service engine. Anyone else experience this issue??? It gave me speed sensor code, I was told calibrate then reprogram speed sensors, then go with 305/35/18 in rear...I need helllppp!!!!

Have to keep the tire diameter within 3% front and rear.

I'm thinking of going with 305/35/18 in the rear and keeping the 275/40/18 in the front, hopefully this resolves the issues. Thanks!

That is within the acceptable range (26.7 vs 26.4 inches)
for future reference use this free calculator:

275/40zr 18 in the front and 295/45zr 18 give you a 6.8% difference. :eek:

275/40-18 and 305/35-18 gives you a 0.8% difference. Much better. :tup:

I read so many threads and keep seeing some conflicting info.

Will I rub?

F 9.5 +15 stock size MPSS
R 10 -5 stock size MPSS

I just bought some SWIFTs on Black Friday and want to make sure I won’t rub since the wheels are fairly aggressive.
