I'm about to purchase a set of Japanese rims, 18X8 in the front and 18X9 in the rear with a 30 offset. The gentleman is selling him rims that were for his 300zx, but now has to sell his car. Will these rims fit my car FD3S with a 30 offset all around?

 

NO.

 

I have 16x8s with 32mm offset and 245/45/16 tires. No rubbing at full compression on stock suspension. 30mm offset might work, but it'll probably vary from car to car. Definitely wouldn't work if your car has a modified suspension. If you decide to buy, select a tire size that is slightly smaller than stock height.

My rims also came from a 300zx. Note that the wheel studs on the Z have a different thread and you will need to get new lugs as well as hubcentric rings for the wheels.
