i found a set of works cr kawami 18x7.5 offset 47. if i use a 7mm spacer will i be fine?

 

Yes, you will be fine, but you're probably going to need extended studs.

 

do you think ill be fine without extended studs? what offset should i like for in 18inche wheels?

 

I wouldn't chance it.... remember, your wheels are held on by your lugnuts, and if your lugs aren't grabbing enough meat from the threads, just imagine what could happen.
Although... I do know some people using 5mm spacers with no problems, but personally I wouldn't chance it.

Regarding offset, what kind of look are you going for? If you're wanting to be flush, even with a 7mm spacer it won't get you there.

 

I heard the max size spacers u can get without extended studs is 6mm. I have 5mm just to be on the safe side.

 

If you're going for a semi-flush look, you'd probably want a 15mm in front, and a 25mm in back. Get something hubcentric like H&R or Ichiba.

 

thanks i appreciate the help. as for the offset im just lookin for anything that fits without rollin or pullin the fender. the look doesnt have to be aggresive at all.

 

I think you'd be OK with 215/40/18 tires, 10mm up front, and 15mm in back. Also, those wheels should work fine without any spacers. The front should clear the suspension by a few millimeters, but a 5mm will be all you need if you need anything at all.
