Wheel & tire combo's

[CheeseSnake]

Don,

My kit is a 1991, with the standard M2 front suspension and 8.8" rear. I bought the following from you a couple of months ago, and want to make sure everything will fit before I order new wheels and tires for the rear;

Front;

Bought from CR;
- Tubular upper and lower control arms, lowers eliminate the radius rod.
- Power brake master, booster and adjustable prop valve.
- Coilovers with Pro-shocks.

Already has M2 disc brakes in front, which will probably get changed out to Wilwood 10-3/4" in future. Current wheels and tires are 8x15 with (I believe) 3-3/4" backspace with P235-60-15. I want to keep the wheels and put P245-60-15 tires on them.


Rear;

Bought from CR;
- Rear coilovers with Pro-shocks.
- Disc brake conversion.

Car has an 8.8" rear, already removed the screw adjuster, boxed the upper and lower arms, and removed the coil perches from the lower arms. Current wheel/tire combo is 8x15 with I believe 3-3/4" backspace and P255-60-15's. I want to order 9-1/2x15 wheels and mount P295-50-15 tires. Will these fit, and do I have to complete the rear disc conversion b4 they will fit? Car currently has the standard Ford drums.

I am getting ready to put the rear back together today, then on to the front suspension. I want to make sure the wheel/tire combo's will fit before I order new front tires and rear wheels and tires.

That wheel and tire combo will fit the rear. Order the 9.5" rear wheels with a 4 1/2 backspace. I would stay with the 8" wheels for the front and don't go any larger than a 245x60x15 or the equivalent in a 50 series.

Don,
I have Team III 10" wheels with 5" backspace with 295x50x15, they stick out 2" past the wheel opening. Is the new 8.8 rear ends wider? Thanks.

Hey Don,
Why didn't my tubular a-arms eliminate the radius rod?

The 8.8 with the Ford rear disc setup is 1 1/2" wider than the older drum rear ends. They are setup for the antilock system. The 10" wheel that you have shouldn't stick out that far. With the 5" backspace and the wider rear they may stick out a little. The lower arms you have use the strut rod setup. The other arm is the strutless type and a frame modification is necessary to use them.

I checked the backspace before I had the tires mounted and they are correct. I don't want the tires to hit the body and I don't want to jack the car way up. Don't know what I'm going to do. Thanks for the response Don. Let me know when I can expect the wheel covers and the rest of my parts. MSO? Have a good day.
