Will this fit? (width, offset and tire size Qs)

here's how i calculated it.

to keep things simple, i converted both wheels to mm.

OEM 7 in. = 177.8mm
CE28N 7.5 in. = 190.5mm

the two wheels are 7.5 in. + 50mm and 7 in. + 48mm.

center lines of both wheels:
OEM = 88.9mm
CE28N = 95.25mm

add the offsets (mounting location):
OEM = 88.9mm + 48mm = 136.9mm
CE28N = 95.25 + 50mm = 145.mm

we now know where the hub is in relation to the wheel per the above calculation.

take the total width subtracted by the mount locations to get the distance from the mount location to the outside wheel.

OEM = 177.8mm - 136.9mm = 40.9mm
CE28N = 190.5mm - 145.25mm = 45.25mm

the difference between the two numbers will tell you how much wider the ce28n is when it's mounted to the hub.

correct me if i'm calculating this completely wrong.

No no, your math is correct. The point I was trying to make to you is that a 48mm offset on a 7" wheel and the same offset on a 7.5" wheel will not equal the same distance from hub mounting surface to edge of the wheel

+44 will fill the gap better, with 50+ the wheel goes more inside, you can do +33 with no issues

Will a 18x9 +42mm offset. With a 245/35 tire rub at full lock with a 1inch drop???

I plan on puttin spacers to make them flush.
Also add some camber.

[TheSlickOne17]

It's actually 18x9 +35mm offset not 42mm

You should be fine. Mine are 17x9 +28. They stick out like a bitch in front, but no rubbing on turns or anything. I'm not dropped, but if anything you'd want camber bolts up front.

With +35, I don't think you'll need spacers.

Will 17x8 ±53 with 225 45 r17s fit up front?

Wouldn't be my choice. May rub the strut up front.

They were free, so a spacer would probably be needed?

Ah, gotcha. Yeah spacer (25mm) would work. Don't buy junk though.
It *may* fit without. But you're getting real close to the strut before mounting the tire..

I would say 15mm to make it plus 38 on the front, 15mm is probably the widest spacer I'd feel comfortable with.

Never ran spacers before, do I do all four or just thr front two?

[JoeBoxer]

All 4 maybe even a bigger one in the rear

There's little to be concerned with using a 25mm spacer if the quality is good. I've used some from Rays Engineering, BORA, Spydertrax and H&R springs, on track and off-road with great success.

Whether or not he wants 10, 15, 20 or 25mm is irrelevant to me. He must choose his own spec. 10mm is hardly going to make or break it, as long as he moves the wheel away from the strut.

That said- I would only recommend ones that come with their own pressed studs. Some people call these wheel adapters even though the p.c.d. doesnt necessarily have to change.

In addition to the studs, "wheel adapters" will be hub or lug centric. They can also be both hub and lug centric if designed for a specific wheel. This reduces any chance of vibration.

I woud not run a "spacer" (plate, no studs) thicker than 8mm without replacing with longer studs.
