I have OEM 19's and thinking about getting new tires (Falken Fk452's) in this size:

Front: 245/35R19
Rear: 255/40R19

Now if i want to get spacers would 15mm front and 20mm rear be nice? Keep in mind, i don't wanna have to roll my fenders so i just want my wheels to be as close to being flushed w/o more work and money spent. Also, should i go for Project Kics, H&R or Eibach spacers??

tire sizes are good... is your G lowerd? id go with 20mm front and 25mm rear H&R

no it's not lowered, but i am planning on lowering it with the eibach pro-kit in the near future. would 20mm front and 25mm rear require me to roll my fenders?

you should be fine but im not 100% sure... PM redlude97 to make sure

I ran 15mm F and 20mm R on stock rims, car is lowered with 350Z H-Techs and no issues what so ever.
