Question

I did a search, but really didn't find what I needed to know.

I am looking at either putting 17x8 with 4.5 bs, or 17x8 with 5.5 bs on my 67 model. It has Hotchkis springs (2" drop on front, will have the 1.5" drop on rear). Will either of these rims fit my car front/rear? If so, what tire size do I need to get f/r? I am getting a good deal on the rims if they fit.

Thanks,

Gary

I have the same suspension set up as you do Gary. I put 17X8 on the rear of my car with 255/45/17 and 4.75" backspacing, then 17X7 on the front with 235/45/17 and 4.5" backspacing. The fit is perfect! The tires just clear the inner edge of the fender lip both front and rear, no rubbing anywhere!

The 17X8 will fit on the front of your car but I would opt for at least 4.75" or 5" backspacing there. With 8" rims I would not go wider than 255 on the rear and 245 on the front or you might have rubbing issues. Some people have had slight rubbing issues with 8"s and 245s on the front which is why I opted for the 7"s and 235s instead.

Thanks for the reply. I think I am just going to try to get them to change the backspacing/width to 17x8 (5" bs) front and 17x9.5 (5.5" bs) rear.

That sounds just about perfect [img]graemlins/thumbsup.gif[/img] ! With the 9.5" rims you can fit up to 275/45/17 but it might be pretty close to the inner wheelwell (you could always massage the well a bit if it rubs any). If you have minitubbed you could go even wider!

I have 5.5BS and 4.75BS with a slight rub on the inner whell well over big bumps. I have drums all round with 1/4" spacers. Just picked up another spacer to make it 1/2" until i get stiffer leafs. Keep in mind that if you put disc brakes it will change your backspacing by about 1/4 - 1/2"

Question

So I need spacers to use the 5.5" backspacing on 17x9.5 rears (drum brakes)?
I have discs up front so I think that the 5" bs on the 17x8's will work.

That is one sweet ride. Why did you put the 1" spacers on the front?

Because an 8" wheel in the front, with only 4" backspacing is not enough. That's why I got mine with 5.25" bs.

I thought that if you had a 1" spacer on 4" offset wheels, the effective offset was only 3"?

I think he really means a 'spring spacer'.

Were the Hotchkis springs too low?

Sorry my bad [img]graemlins/clonk.gif[/img] My rears are 8" but my fronts are7" wide. I put 1" coil spring spacers to raise the front up a bit. Got some rubbing on dips at freeway speeds with passengers in the car.Ray

Ray, what is the measurement from the center of the rim to the fender lip on both the front and rear?
