Wheel Sizes

Newbe here. I have a CC2 kit I am finishing for a customer.
He wants to run 16" front and 17" rear wheels & tires.
What off-sets are recommended? What width front and rear? What tire diameter?
I don't want any clearance issues for this customer? We intend to run traditional Cobra wheel style.

Sorry guys. Correction. Its not a CC2. I am finishing up a Classic Roadster 2 that was purchased in about 1993-1994. This was one of the last complete kits sold before Classic Roadsters filed chapter 11 back then. I am at the paint stage and will be finishing the car in about 8 weeks. I need some help with max wheel width front and rear as well as back spacing along with max tire width so I can advise the customer and he can purchase wheels..
Need some help from those of you have that have CR2's on what your able to fit to the body. I was told this was the best forum. All of you are the experts wilth lots of experience with this kit.
Thanks. Robert.

Don Scott built my CR I in 1999, he used:

Front: 8" wheels , 4" backspace, 245X60X15

Rear: 9" wheels, 4.6" backspace. 275X60X15

Above using Compomotive HB wheels

....not implying this is or is not correct for your application, but just one example.

Check with Vintage wheels they advertise on this site. They have some good wheel dimension info here http://www.vintagewheelsus.com/tech.php
One of the best things to do in my opinion is to bolt a wheel onto the hubs and start measuring how wide and how far in or out you want it.

Don / Mickmate. Thanks very much ! That gives me somewhere to start regarding 8" front and 9" rear and backspacing. It's also close to the tire sizes I thought would work with the basic measurements I took off the car. I can take those typical tire diameters and convert to metric 16 & 17" sizes..

If anyone else can contribute to what tires they have on there CR2's it would help to make the correct decision first time. I found a picture when the car was deilvered and the grill opening had a number #259 written on it. I suspect is was kit # 259? The owner did get a manufactures certificate so hopefully in 8-10 weeks he will be driving this thing.

Sorry to you true Ford guys, this car has all aluminum bow-tie 400 CI small block, 10-1 compression, .550" lift hydralic roller cam, phase 6 bow-tie ported heads, alum pan, 750 holley, aprox 550HP. Dual disc clutch, 6 speed T56 overdrive trans, Moser 9" ford, aluminum center section, 3.90 gears. Aluminum radiator. 1 3/4" hand built tuned headers. A Leathal combination.

Robert,
I'm running 245/45 R17's on front and 275/40 R17's on the rear all on Cobra R wheels. There's room for more with the right backspacing. Goodyear Billboards go on as soon as everything is sorted out. 26-10/15 and 26-12/15 respectively.

Oh yeah, I like that motor combination!
