I will be purchasing some JIC coilovers for my 1990 240sx. I have rims as well. I have some Konig's. They are w/ dunlop f901 205/40/17

Do I need spaces?

I think You mean spacers not spaces. Im not being a smart *** but let me explain some stuff to you. Ok, when making sure or wanting to know if a rim will clear you strut and spiring or coil overs one of the biggest key factors you forgot to mention about your rims is the off set. This factor judges how far in or out the rims sits in your wheel well. The higher the offset the closer the rims will be to your coil overs, the lower obviously, means it will sit further away. And you also didnt mention the width of your rims. But anyway to answer your question your gettin full coil overs (JIC) which make more room for the rim, and your running 205/40/17 tires so im assuming your rims are 7inches wide. And most konigs have a +40 offset so they will be fine.

sorry if it a little bit long

you never kn0w until you test fit the wheel. you can make a good guess if you know the wheel size(width and diameter) and its offset, and the tire size you are running....

but theres still no gaurauntees.-chet

I have Konig Verdicts in 17x7.5" with a +40 offset and I have to use spacers...

anyhting over 32-35 off sett with 7.5-8 inch wheel you probaly will have to

I want to know whats the widest i could go in the rear of an s13. Can i install 18*8.5 or 17*8.5 what's the widest size tire i could use and what offset will i need in order for the wheel not to rub against anything. Thank you very much foor any help.

Depends... you can run a 17x9 +30 offset wheel on the S14 w/o any rubbing, from what I know the S13 has less room than the S14.

If those Konigs are 7" wide and have an offset of +40 then you are safe.

I ran 16x7 +40 w/ a 215/45/16

Ok what i wanted to do as get 18x8 with some 235/50 tires in the back, what kind of offset will i need and will these rub or will i need smaler tires, cause i didnt' want to get a whole new set of rims, i wanted to get the ones i have just the two rear ones bigger. thanks
