i try search for this, and i fond it, i read it, but i have not idea what it means
hope u guys could help me
thx

I would say a 15-20mm spacer would be good depending on how flush you want it to look. As for tires a 225 up front and 235 out back should look fine. You may have to roll the fenders. Unless you got a real amazing deal on these you may want to sell them and buy rims with offsets that are better suited to our cars.

Is this on an s13 or s14?

its for an s14
but for 235 rear will that cut the tire when i am on the bumply road

just leave it.

Gram lights should clear the Z brakes and your stock rims are 16 x 6.5 +40 i believe.

an 8 inch wide rim will be 18mm street-side compared to the stocker

8 - 6.5 = 1.5" = 36mm / 2 = 18mm

i think that is about right seeing how the offset is the same.

run a 5mm plate up front if you want to make it slightly mroe flush without dealing with the fiasco of spacers and studs.

235s should be fine. I’m running larger tires with a similar offset wheel and haven’t had any problems yet.
