spring questions?

[3VoL]

so I currently have a 90 240sx and I ordered Koni 8610-1436 for the front and 8041-1208 for the rear. I was thinking of just getting GC coils but I'v also come by a decient price for hyper coils and I'm just wondering if having a 18x8 front and 18x9 rear is possible with a 7" 2.5" ID springs? I'v spent a lot of time looking on this site but I'm a little confused abou fitment. I haven't bought the springs or the rims yet, but have everything else.

The offsets of the wheels and tire sizes effect how much clearance you're going to have so you should post those up too.

Yes, you should easily be able to fit even a 9" wide wheel up front, and the rear has tons of room - a 10" is easy back there with a roll.

sorry +15 offset with 255/40r18 in the rear and 235/40r18 in the front... so this will work with the 7" springs... and I need 2.5"ID springs?

That should work fine. Spring ID is dictated by collar/perches you are using, but most are 2.5" ID.
