Looking at some used speedline rep. wheels. My car is an '86 therefore, early offset. the wheels in question are as follows:

Front: 18 x 8 ET 52, Tires 225/40/18

Rear: 18 x 9.5 ET 47, Tires 285/30/18

By my calculations, (52-23 & 47-23) I would need 29mm and 24mm spacers.

Is this correct and can anyone verify if this combo would work on my early offset car?

I did try search, but couldn't find info for these exact sizes. Thanks.

I'm running 285/30-18s with 15MM adaptecs in the rear. 6MM in the front. I wouldn't use math to order the spacers. Use large washers on 3 of the studs until the tires fit well. Measure the thickness of the stack and place the order.

Same offsets as yours.

I wish I would have done the type of measurement instead of the math. I did the math and wish i would have gotten 1/4" larger spacers.

Sounds like they will fit then, just need to do the washer trick.

Ted: So, no need to roll the fenders then? The 285's must look awsome on your car! Where did you purchase the adaptec spacers?

Thanks for the replies.

Order the adaptec spacer/adapters from them directly. They are awesome to deal with.

Ditto on adaptec. No fender rolling. When I first installed the wides, I thought it looked a little like a clown car. I have no need for 285 on 10.5s, but they just look right, to me.

Now when I see pictures of it with phonedials, I cant figure out how I liked it so much.

BTW, I did have to move the ebrake cables inboard a hair to clear the backside of the tires.

I am running 245/40 18's on the front and got minor rubbing at a DE 2 weeks ago. Finally decided that rolling the fenders will have to be done or risk slicing a side wall @ 100 mph.

235/40-18 needed no rolling, but 6MM spacers to keep them off the coil springs.
