You guys should really consider these before studs. I ran them with a 1/4 spacer on Buick Regal -T and they were great. IF you find you still don't have enough thread then get studs.

Besides if you do studs aren't you hosed if you go back stock since the factory lugs are closed end?

Yea. When I bought the extended lug nuts I needed to cut them down to fit them under the closed end nuts with the red ends. Well when I had them on the lathe I set what I thought was the right length, and my friend said they were too long, and I ignored him and they are. They are a 1/16 of an inch too long so they punch through and ruined all the red centers just knocking them out. this pissed me off because I loved those red centers. I might paint the end of the studs red for looks.

And I won't have to worry about going back to the original wheels because I'm butting big brakes on which won't fit under any wheels smaller than 17 inch.

It seems strange YO didn't use the lugs they push with the rims.

I threw some 17x9 YO snowflakes on the 67 bird to get some measurements.

I emailed Year One:
"I have recently purchased the Pontiac Rallye 2 17x9 aluminum wheels and I am concerned about the thread engagement of the lug nuts. It seems the wheel is thicker than a standard steel wheel and the thread engagement is much less. Do you know what the corrective action for this is? Do I need to purchase longer wheel studs or extended tip (ET) lug nuts? I was wondering if this issue was encountereed during product development and how it was addressed."

and this is what they said:
"The thread engagement depends on the length of the existing lug studs. When people find less than minimum thread engagement we recommend extended shank lug nuts as this is easier than locating and installing longer stock type studs. We do not usually recommend racing type long studs as they are too long to use with capped lug nuts and require open ended nuts."

So I ordered a set of ET lugs from Summit. I'll let you know if they fit or not.

I put the Billet Specialties ET lugs on and they work fine. Just be aware - they come in 10 packs not 20. So now I have order another.

Exclamation 17x8 now available

Checked Year One's website tonight and found out the 17x8 version is now available with 4.5" backspacing:

I have 1/2 inch diameter studs... Would this be a problem? Just checking.

I will contact YO.... but maybe those with the wheels might have a more objective opinion.

Thanks

I haven't checked with YO since I am a few months away from getting wheels. I checked some shop rollers and they seem to work. But you never know. I would think it should not be a problem. Would like to hear from those who actually have these wheels.

Anyone?

Just pre-ordered two of the 8" rims. If you look earlier in the thread I documented installation of the 9" rims on my 68 Firebird and found an 8" would be perfect. This means I will have (2) excellent condition 9" rims available for sale in October for those looking to save some coin.

I thought it looked great with those 9" wheels in front. I didnt see it as a "low rider" look at all. More like a mean, wide stance road racer look. Its your car, but I thought it looked awesome!

Firebirdmi, I wanted to also compliment your car. My 68 Firebird currently has torq thrusts that were installed by the previous owner, with less than optimal backspacing. After flipflopping between 200S, V45, V40 and the Rally 2 wheels, I've decided to use your car as inspiration and go with the rallys.

My only question is this: you chose 255's for the rears with the 17 x 9 wheels. Had you chosen the 17 x 8 wheels with the same 255 tires, how do you suppose the look or clearance against the rear fender would change?

With the 9" rim and 255/45 tire, the sidewall is essentially square. I believe that tire with an 8" rim would give it a meatier look with about 1/2" bulge per side.

As for clearance to the wheel well opening there would be 1/2" more than what is shown in the pictures. My car has been lowered about 2 inches all around and I rolled the rear fender well lips during construction. I don't have an issue with my existing setup rubbing the qtr. panel and believe if you were to go with the 8" that has a 4.5" backspace it would provide added insurance against rubbing and possibly boardering on overkill. Do note I have not installed the rear axle bump stop yet which would provide additional insurance against rubbing as the suspension bottoms out.

debating on getting these i have a 71 lemans wagon that has coilovers in the rear and coilover conversion kit for the front. ive been told the car is slammed, but to me its not that low. im running 15x8 honeycombs currently but i like the look of the 17x8 new rallyeIIs.

im concerned with rubbing on the liners in the front, i also have a bump steer kit from spohn performance which drops the outer tierods fairly low. is anyone else running a similar set up? my rear quarters are rolled and pulled so i have no worries about that.
