Title: Trans am rims on a s12???
Post by: ka-tgazelle on 12:57:33 AM / 05-May-11
A  early 90's late 80's trans am lug pattern is 5x115 or 5x4.53.... Just a tiny bit different than an s12 but you can make it work with little to no modification.

I think they  would look sick on an se........  They have a little more of a lip than the crown vics.....

Considering they are alot easier to find than crown vic rims any ways considering most people who own these cars put cragars on them anyways.

it will fit 5x4.5 and 5x4.53 are   millimeters difference your quick to shoot down any idea i have.

Post Merge: 01:37:29 AM / 05-May-11
get a tape measure and see the difference its enough to just drill out the holes to bit a tiny bit bigger

Post by: Jay on 02:06:15 AM / 05-May-11
Millimeters?!?!
5x114.3 vs 5x115
it's .7 of 1 mm....

Either way. I wouldn't touch it with a 10 foot pole. Drilling/opening the holes a little will do zero good when the taper for the lug nuts center on the original hole.

go for it if you want your rim to start wobbling a week later. my stock turbo rim had one hole that was off by about 1 mm and it wobbled so bad that after only a week of driving on it, tightening it every day, until i got a new rim that it ate through all the mounting points for all 4 lugs. just something to think about.

You guys do realize they make adapters right???...... THe one thing i dont like about this site is NO ONE is open minded and to affraid to try to things...... Its not enough to make a difference.... you ever had non hub centric rims on your car??? I have on my 240 and my s12.......

Looking in to it THEY WILL work you need hub center rings...... ohhh now hub centric rings.... Yay for me you guys and say im wrong all day Im running  non hub centric rims on my car now and dont have an issue, so is my buddy and his g35 and a girl i knoq on her 98 impreza 2.5 rs and both run centering rings. Ever wonder why universal rims holes are a tad bit bigger than normally and not hub centering....... Thats the reason ive been reading in to it.... The crown vic rims are getting old and could big wider and have more of a dish.

putting wheels that don't match a bolt pattern isn't a "New idea".
Filling in, and redrilling wheels is not a "New Idea". and that would be the proper way of going about it.

What you are doing, is trying something. Nothing more
Will it work? Maybe. Maybe not. I'm just personally not willing to have a wheel be .35 mm off on it's mount. That, while it may not be to you, is a fucking HUGE difference when it comes to a wheel, with weight on it, that turns at decent RPM... With hubcentric spacers, you STILL have the lug nut taper that points to the center of the hole, which is not center to the vehicles hub, even with the spacer. It will always be that little bit off, and possibly not tighten fully. This is basically the same principle as a wheel being "Out of round"...

and, of course you have no hub centric wheels on your car and right now, and are fine. Because you have LUG centric wheels..... That's what they're made to be...

Do whatever you want to do. You asked our opinion, we voiced our voice calmly (What you ASKED for) and then you go and attack us by saying "We're not open to new ideas"???

If your so hell bent on "Trying a new idea", then do it. and leave the "everyone on here doesnt like any  new ideas" ideology at the door.

As my opinion, I wouldn't do it.
Because for safety reasons it's like destroying the integrity of the wheel and / or balance of the car, re-drilling the wheel or different offsets changes what was already been set for the wheel in itself kinda upsets the balance already in place for your safety, last thing you need to do is use a spacer that snaps while driving or a drilled wheel breaks under pressure and causing you to wipe out.

plus Trans-Am messes look best on Trans-Am cars.
They already make tons of good rim styles for the s12/s13/s14/z31/z32/z33 etc... 4 and 5 lugs.  14 - 18's

but that is my opinion tho.
Have fun with the wheel mod if you do, make sure it's going to be safe. I don't mean to offset this as a negativity, but as an opinion.
everyone is free to do what they want to do. I just say cool, hopefully they don't forget the safety of others and themselves in the process.

Post by: Athens on 04:56:42 AM / 05-May-11
ok one thing im not getting here.
You come on here posting about using a rim that doesnt normally fit on an s12 by boring out the mounting holes and ask for opinions on this. Then, when you get opinions that are negative, you immediately dismiss them as not being open minded/hating new ideas instead of thinking that, maybe, they just might be onto something and weighing it against your own opinion.
Realistically, its not opinion, its a fact that if you bore out the holes with a drill it wont work. Eventually the rim will wobble off center on one lug and will start moving, boring out the mounting holes until eventually it wont even hold on anymore. That was exactly what happened with my rim, except it wasnt drilled, the previous owner used a lug nut that didnt work with the lug style the turbo s12 rims use on one lug and eventually it came loose. The same thing would happen with drilling it out too, except it would be much faster because it would be off on all 5 instead of just one. With a spacer it would be a different story because you could just get one that has s12 on input and trans am on output, so if you are dead set on using a trans am rim instead of just getting a meshie that already fits on the s12, then go on ebay and get a spacer adapter and be done with it.

been done on an s12.
check visual mods(i think thats where they put it)
someone did foxbody stang wheels as well.

there was no wobble...for all you nay sayers........

you can also change the wheel studs....

so: not a new idea, not impossible, should listen to people,all should lighten up....good day.

I own a Trans Am. Thats 5 x 4.75 not 5 x 4.5whatever.

GM runs a 4.75 and Ford, Chrysler, Nissan run a 4.5. There are uni-lug wheels that fit both of thse bolt patterns. It's been done, but I just don't like it.

Ive done 135ish with my rims i have now WHICH btw are american racing wheels and with no tires wiegh 16lbs.......  Wieghed them bitches last night.   I think the trans am rims are much easier to find and are a bolt on rim. I found DOZENs of older guys running  newer crown vic steelies on there old dodge darts on this certain forum and the old darts use 5x4.53... Its   not a big enough difference to change anything. 

Post Merge: [time]04:44:25 PM / 05-May-11 [/time]
The newer trans am's use 4.75 but the ones i am talking about are 5x115 which converts to 5x4.53... Its literally not a big enough difference to change anything the studs on a trans am are bigger than mine as well. Im running my rims i have now  but was thinking maybe some where down the road  i could use them .... Its just a thought  . Imo its to small of a difference to make it dangerous otherwise non hub centric rims would cause this problem to.... EVERYONE READ my above posts before thinking  for them to work you have to drill them out...

Ok, but I have a second Gen T/A and I'm using third Gen 1LE 12" rotors and I know those are 5 x 4.75. Different than Ford or Chrysler. I can also tell you that those GM 16x8 Meshes have different offset from the front to the back - zero offset fronts, 16mm offset rears.

I'm not detering you. I like those wheels. I'm just telling you what I know.
Title: Re: Trans am rims on a s12???
Post by: Taris Blue on 05:47:42 PM / 05-May-11
The wheels you are talking about are 5x120...they just are, and they won't fit on an s12.  Now putting a 5x115 (grand prix/grand am) on an s12 will work just fine as long as you are running hub centric rings...I've run 5x115 on a z31 for many years without any issues and also run 5x114.3 on my brother's grand prix without any issues...we are talking about a difference of .35mm total radius of difference here...machining tolerances for many aftermarket wheel's are not much better than that in any case...it's somewhat a mute point on your original question however because no year Trans Am wheels will fit on an S12 without adapters.
Title: Re: Trans am rims on a s12???
Post by: Arro on 03:25:51 PM / 17-May-11
Let me summarize all this crap...

Those wheels you want to run are 5x120, and yes, I agree, they look great. You would need a hubcentric spacer to go from 5x114.3 to 5x120. You can't get those spacers in 4x114.3 to 5x120. I looked into this two years ago for these exact same wheels, from a Formula Firebird.

What is more, when you use spacers that change the bolt pattern, there is a minimum thickness that will work for them. Usually the minimum is THICKER than the minimum for a hubcentric spacer that goes from same pattern to same pattern. This is because it needs to maintain metallurgic integrity between the bores for the studs. So what you are left with is a low offset wheel, which will portrude from your front, and adding to that a 3/4" spacer (approx.) thus shoving the wheel even further outward.

This doesn't take into account that you will have to switch to SE five lug hubs on the front and back, because as I said, I wasn't able to locate 4x114.3 to 5x120... only 5x114.3 to 5x120. So there's a lot of work just to stick out vato-style, for wheels that, while they look nice, they also happen to look like literally a dozen various  mesh knock-off wheels available in both four and five lug 114.3 and in offsets more palatable to our cars.

So the spacer idea is a flop.

Slotting wheels is fucking retarded, and I won't even consider the notion worthy of more comment than this one sentence.

Filling and drilling wheels is largely limited by the design of the wheel, of which MOST (not all) mesh styles do not provide adequate space to do so. This will also sometimes lead to cracking of a wheel, again depending on the style. And again, mesh wheels are not very tolerant to redrilling. Most wheels that get redrilled have a more solid construction to them. Even then, it's a total waste of time and money to make a wheel bolt up that will poke, when there are (again) many mesh knockoff options that look similar (or even the same) as these Firebird wheels.

Further discussion of this is, much like the idea of slotting, retarded.

That's a sure way to snap the studs right off the hub. If any one statement in this thread is heeded, it should be this: Don't fuck with incorrect bolt patterns in a dumbass attempt to make them fit. Wheels are a serious safety topic, possibly the most important safety topic on a car. DO IT RIGHT.

My opinion, and I would have done this with all four corners of my car if it werent sra, is just convert to se 5lugs.  Better brake options for the front and rear and you wont have to rely on spacer/adapters to hold your wheels on and to make them poke more than they already would.  I had to use adapters in the rear but sra guys are kind of sol when it comes to 5 lug conversions. 

Also if you go with the 5x114.3 and you are looking for low offset wheels, the majority of wheels sold for jeeps are the same bolt patter and can be had for cheep cheep cheep!

You can also go Z31 NA four lug, if you want to stick with four lug... the brakes and disc rotors are the same as the SE i.e. bigger than four lug.

But regardless, these trans am wheels won't work.

I don't have anything against you personally, I just think it doesn't look good. If you're going to fill in and taper the lip, then when you're done I'll revise judgement. I haven't seen what David has done recently, so that doesn't apply to me.
