Yea.. from now on i'll pay to have my tires mounted. I had a hard enough time mounting my 225/45/17's on my car. I even used a tire machine and wheel balancer. (my bosses shop rocks)

About the 16x9 wheel and tires
My Conquest has 16x8 and 16x9 wheels stock and I have 255/50/16 and it doesn't look that bad. Gives the car a tough look
I'll get some pics if you guys want

By going with a 265 rear, 225 front, you will only be increasing your car's tendency to understeer. The stock tires on your 951 were 205-55/16 front, 225-50/16 rear. That's a 20mm difference in tread width. Porsche did this in oder to have understeer built into our cars. Why? The perception is that an understeering car is easier to get back in control given an average driver. (Car understeers, driver slows down, car stops understeering).
With your requested setup, you are now going to have a 40mm difference, making the understeer even worse. While understeer is good thing for the average driver, if you are an enthusiast, and are invovled with autocross, Driver's Ed, Club Racing...etc, then you will want to dial out as much of that understeer as possible, with the goal of making your car more neutral in handling. (Ok, maybe with a hint of oversteer!
) That said, you can fit a 245/45-16 on your front 8-inch rims. Even if your car has been lowered, you shouldn't have any clearance issues, provided you have the proper offset wheels and a good alignment.

I love all things turbo cup.
But the wheels are not practical. At this point they are museum pieces or great conversation pieces...yeah my coffee table is made from a turbo cup wheel....there was this race series in the later part of the 80's.....
But it is just too easy on wheels to go faux.
White powder coat and you are done.

I agree but...I was told 225 is the largest size I could fit with stock suspension.

"The rears are WAY too tall. If someone buys them you will want a 245/45R16 in the rear and a 225/50R16 in the front. Cool find though."
Why would you want a taller tire on the front than the rear?
225/50s are .1" taller than 245/45s.

"Ahh yes, bad thing about having a 9x16 rim. Even thou you can put wider tires on it than 245, good luck finding them."
Just buy a set of 255/45/16s.
They're 10mm wider than 245s.
Bridgestone makes that size, probably others as well.

9fifty1 is using 18" wheels NOT 16" wheels. While it would tend to make the car understeer a little more he is making more than enough power to overpower the rears
Because with an 8 and 9" wheel it is the best setup. That is .1" trust me you will never know it.
No, we dont and neither does anyone else with a brand name. Please, show me what you have. We havent made that size in about 8 years, if not longer.

Nope, they aren't simply 10mm wider. That measurement is around the tire from outer lip to inner lip bead. So they are a little wider, and a little taller.
For example:
205/50R16 is shorter than
225/50R16 which is shorter than
245/50R16 which is shorter than
265/50R16
etc.
