Blue 90 RS

I used 2.25" adapters in front and 2" in rear. Any less on the front and things would rub/interfere. Front adapters are hub-centric. Rear adapters are hub- and wheel-centric. I made no modifications to the car itself, and I'm running Eibach Pro Kit springs which lower the car 1".

Ive been looking at those Centerline Split Spokes myself. What bs are they? Are you happy with them? Is your car lowered? BTW your car looks awesome!

mene0013

What rims are those, really nice.

Thanks, The car is running Eibach Pro-kit springs. It was a bit lower in the rear until the Koni "yellow" were installed.

I've been a long time fan of centerline wheels. I love the "split spokes", I am running 17"x9.5" with a 5.5" BS on the rear and a 17"x8" with a 4.5" BS on the front. If I had it do do again I would run 6.0 and 5.0 BS since my aftermarket brakes bumped the wheels out about 1/4".

I've attached the Centerline box labels if you want more info.

*EDIT
The car has since settled from the photos above, see last thumbnail below.

Chaz-Man

Thanks for the info, very helpful. I'm thinking of going 17x9.5 all around but not sure yet. Really like how your looks

They're not as nice as some of the wheels I seen here but I got a decent set of American Racing outlaw II wheels on mine.

I believe they're 15"s I'm looking to replace them since every jeep has these exact wheels

ziggy89

H town those wheels look awesome. Did you order from summit or find a place with a deal?

H-TownMinion

iTrader: (1)

Thanks Ziggy, I ordered direct from Centerline via telephone. I wanted to make sure there was no confusion regarding size and back spacing since there were none on the shelf at the time and they had to make them. I believe I waited a little over a week for delivery.

Waiting a week for a wheel that had to be made isn't bad.

Woah, I realized that I had not replied to this post. I thought I had, but after checking the last few pages.. looks like I never did.

I'm quite partial to these wheels I put on the car in June:

Boze ZE Forged INJECTED

Front are 18"x8" with a 5" backspace and a Nitto 555 245/40/18 tire
Rear are 18"x10" with a 5.875" backspace and a Nitto 555 285/40/18 tire

Damn, I love this car! I would like to run a 255/40 front and 315/35 rear. Will the 315 fit on these cars and is so, what backspacing? Not sure yet if I'm going with 17 or 18's. I have a 4th gen rearend (Strange S60) and Wilwood brakes on all 4 corners. Running 275/40/17's all around right now. Any help will be greatly appreciated. Thank you in advance.

SirHarley

Awsome setup. I have been follwing this thread for a while now. Has any body any pictures of a Third Gen Firebird/TA with the New 10" wide Rally 2 rims. I have been looking but there is not much out there. I know that up until 1986 Pontiac sold base Firebirds with these in 7" wide form. They were usually color modded with a black plastic center cap. I would like to see a 10" wide Rally rim with some bigger meat on there.

claus290373, do you have any better pictures? Some outdoor shots perhaps? What color is the car?

nhgator

I have 8" rally's from summit with 235/60's,I didn't see the 10's when I got them but that was a while back.

SirHarley

That looks really nice Gator' In fact they look like they belong there. Are those 15 x 8 or the larger diameters?

claus290373

hello
The color i purple not my color but there are only a few trans am gta i denmark so i just had to buy the car. It is stored for the winter,but i will do some outdoor shoots for u next weekend(21-22 feb).

CharcoalBird

iTrader: (4)

Thank you. Honestly, the shade of purple used looks fantastic. Do not feel the color takes away from the car as it is unique and compliments it well. At least it isn't a bright purple or the like. Good buy.

nhgator

Those are 15"x8" but they are dished deeper than factory 15"x8"'s,I wasn't sure when I ordered them but I really like them,I think they look better without the trim rings.

SirHarley

Hey' dont knock it, if no trim rings are good enough for "The Judge" who are we to say anything. Remember, if it doesnt make it go any faster throw if off for weight...

Danny_VXH

IMO the best looking rims for the Pontiac's will always be the good old honeycomb rims. Big rims just don't look right on a muscle car if you ask me.

Just made mine shine again.

Before:


After:

With some nice 245 wide tires:


PS, just wondering. When i look around on the interwebz, most 3rd gen honeycomb rims look like this:


Which looks like the ones i got, but they are not. Just wondering if anybody knows why?

SirHarley

I always thought those were Snowflake wheels. The Honeycomb wheels came on the mid 70's TA's. They had a 5 sided pentagon shape to the web. Your wheels came on a 3rd Gen GTA I think. The Formula wheels (WS6) were dished a bit differently because of the backspacing. Does anyone know if the GTA line of wheels had a similar wheel design becxause they all had the WS6 package anyways.

okfoz

Danny, Are those 15" or 16" wheels, I cannot tell.. I can make out 225/60R and it stops there...

There were two different style wheels, the early 86 & 87 Wheel, and the 88-92 Wheel. The later wheel have the dimples, the early ones do not. Your wheels look similar, but there is something amiss. The spokes do not meet at the rim which is really throwing me off... I wonder if what you have is some sort of aftermarket wheel that just looks like the other wheel...

okfoz

Have you ever noticed that there is almost a Pontiac symbol in the cross laced rims?

Bob88GTA

iTrader: (2)

Oh my......How long did you stare at that to come up with that????
Is THAT cool or what!!!!
Good eye!

SirHarley

Okay...those arent snowflake wheels. But GTA's did carry a similar wheel. There is a lot of great wheel info on "Hitmans Trans AM website...heres a link

Makes me what to run out and look at em!

I'll do that when I get home. Show the wife what I discovered!!!!!

okfoz

I want royalties...

Actually it is really close, but not quite exact... the side lines are not quite straight, they do bow out a little... But if you look at Danny_VXH's pictures of his wheels that are not the GTA wheels I spotted it, but you have to extend the lines to the points... For some reason the pattern just jumped out at me. So I started looking at the typical GTA wheel and I could still see it...

Danny_VXH

They are 16'' and all four of them have an small offset on the back on the rim it self.
The previous owner had put on some 225/60/16 tires on it, i however now added some 245/50/16's on it. The old tires just didn't seem right and on the inside of the doors the labels said correct tire size was 245/50/16 i believe.

At that point i didn't know much at all about 3rd gens.

Its a 1986 Trans Am, this is a picture of the car when i just bought it and took it for a spin for the first time after changing some things 'had been standing still for 15 years in a dry place with these rims in the old dirty condition':



Here are some larger pictures of the wheel it self:



Maybe its just that its the 1986 Trans Am like you said, but then again, something about the rims just look a bit different from what i'm seeing on other Trans Ams.

PS has anybody noticed these Trans Am/GTA rims also look exactly the same as the rims on the 1982 Dodge PPG M4S Turbo Interceptor? Also seen in that old 80's movie ''Wraith''
