Hey everyone!
I've come across a set of SSR D5Rs in excellent condition and I'm seriously considering getting them for my 2016 370z base model with base brakes. The specs for the wheels are Front: 18x9.5 +25 and Rear: 18x10 +27. I currently have 235/40 tires upfront and 275/35 in the rear, and I'm running on BC coilovers. Can someone please confirm if these specifications will fit my car without any issues? Can anyone give suggestions for me.
Thank you!

I can’t be certain they will clear the calipers , but probably will. I would suggest you will want a set of 10mm spacers.

I also suggest a 245/40 front and 275/40 rear tire

Thanks for the reply! I'm happy you mentioned that the wheels might clear the calipers, but using 10mm spacers could help if needed. Also, your suggestion of using 245/40 front and 275/40 rear tires is really helpful! Make sure your mobile, PC, or tablet has a reliable internet connection through browsers like Google Chrome, Safari, or Firefox to access the NJMCDirect, especially during specific payment hours.

Careful with sizing. Z34 tire setups are NOT the same as Z33 (which terrasmak quoted).

Front tire on Z34 is actually taller than the rear tire (opposite the Z33 F/R stagger) and almost equal diameter so the age old "Z33 3% stagger ratio" does not carry over to the Z34. Z34's VDC/TCS system is tuned for less than 1% delta F-R and wheel speeds are slightly LOWER on the front end of the 34.

Stock Z34 18's are:

225/50-18 26.86" (diameter) Front
245/45-18 26.68" Rear

And 19s (Sport Pkg) are:

245/40-19 26.72" Front
275/35-19 26.58" Rear

To match up a set, better/closest 18" sizes (to keep to stagger correct) would be:

245/45-18 Front 26.68"
275/40-18 Rear 26.66"

This sizing maintains the OE diameters +/- little/insignificant amount - which is key because of the standard VDC across the trim lines. It also illustrates why most wheel upsize/upgrades on Z34 are +1 or 19" wheels. (Sport and Nismo Pkgs have 19" standard.) This gives more sizing options whilst keeping the wheel speed sensors happy.
