Put a set of XXRs I picked up cheap on my new daily 92 Z28. They where a brownish gunmetal color but I stripped the paint off and plasti dipped the centers. Look pretty good for $250.



Dont mind the strech poke tires on the front. Came with the wheels. LOL

Can't really see them in that picture. The front looks way too wide. Almost like an RC car.

You just need a bunch of negative camber and bend the rear axle tubes till the outer lip of the rims touch the fenders

Honestly can't see anything from the dark pic. Would like to see it though.

LOL those tires look hilarious on there.

The wheels seem like they will look decent but Im not sure about the backspacing on teh front. Probably will look a lot better with properly sized tires on it.

So what did you do about the bolt pattern?

iTrader: (5)

I'll try and take some better pics today.

Yes the tires are LOL. Should be fixing that today.

What about the bolt pattern?

yes there are cheap wheels but allows me to drive and save up for better ones and engine in future lol
dont mind exhuast i cut that off hanging to low lol

im running 1in spacer/adapter rear hubcentric and 1.25in front hubcentric 18x10 all around when i upgrade to ls1 brake setup hopfully with cts-v calipers if wife allows lol ill runn 1in spacer/adapter tires size are 285/35/18s all around 295 in rear might fit but it might be to close to fender with 1in spacer you might have to run slip on spacer and extended bolts hopw that helps any i have no issues driving and im lowered quite a bit on freeway or around city

i will get new pics up shortly after fixing some starting gremlins with t56 swap

you whould need tuner style lug nuts also any other questions let me know

and thats a steal for 250 great deal

paul_huryk

Make sure you verify the CTS-V brakes will fit before you buy them. Not all 18" wheels will accommodate them, you may have a problem with caliper face to rear of wheel spoke contact with mesh wheels.

I believe those are 5x120mm wheels?

Our cars are 5x4.75"

Zach/90\irocZ

iTrader: (6)

yes im aware of that no two wheels are the same i will fit measure.. measure fit again measure ..test fit routine lol i will run ls1 brakes "i got for free lol" for now till i can get a caliper to test fit im going to use cts-v 4 piston not the new 6 piston for the 2nd gen cts-v i think widths are about the same unsure tho if it doesnt fit just another exuse i can use to get better new wheels yours are in my top running for next pair of wheels lol
thanks for the heads up paul

Zach/90\irocZ

iTrader: (6)

yes your correct there 120mmx5 bolt pattern you wil have to run hubcentric wheel spacers or adapter or get a adapter that goes to 120mm bolt pattern.... can you bolt the 120mm to the 4.75" yes you can... longevity wise the stress you put on the bolts is debatable..... but some people have issues and alot others dont have issues.... if you run spacer i highly suggest hubcentric to relieve some of the load from bolts if any is relived and to center wheel properly...

87350IROC

iTrader: (2)

I have this setup laying around at home and can take some measurements for you.

87350IROC

iTrader: (2)

If you have to run a spacer anyway, I would get one that adapts the bolt pattern correctly. The stress on the bolts really isn't debatable. What is debatable is whether the additional stress is enough to cause a failure. Obviously, as you point out, many people run 5x120mm wheels without apparent problem. I'm not saying you will have a problem, I'm just saying you have cut into your safety margin. Bolts are not designed to take load in the sideways, shear, direction. They are only designed to take load in the tension, elongation, direction. By bending the bolts you are exposing the valleys of the thread to additional stress. The valleys are sharp and are a perfect place for a crack to propagate.

The popularity of the 5x120mm bolt pattern is why I am working on a hub design that has dual 5x4.75" and 5x120mm bolt patterns.

Finally, hubcentric wheels. The hubcentric feature of some wheels does absolutely nothing to the strength of the connection. It takes none of the load unless the lugs are stupid loose. The load carrying capability of the wheel/hub connection comes from the friction generated between those two surfaces. Friction relies on a clamping force to carry the load. Ff = mu * Fn. Ff is the frictional force, mu is the coefficient of friction between the wheel and rotor, and Fn the normal (clamping) force is due to the lug nuts clamping the components together.

A M12 lug at 80ft-lbs generates about 10,000lbs of clamping force. There are 5 lugs so 50,000lbs of clamping force per wheel. The coefficient of friction between the iron and aluminum is about 0.6. So the friction force is 50000*0.6 = 30000lbs. This is the force that is available to transmit all the loads from the the wheel to the car. Only when the load exceeds 30000lbs would the hub centric fit take any load. This is designed to never happen, as the bolts would also take a side load. Bolts are almost never designed to take a side load. If the hub centric area was taking a load, you would see wear in that area.

I hate to be that guy, always repeating this information. But I feel strongly that at the very least everyone should be aware of the risk and make an informed decision.

Zach/90\irocZ

iTrader: (6)

that would be helpful you can pm me the measurements i know 04-07 CTS-V Calipers are direct bolt on using 06+ Corvette Z06 Rotors on a ls1 brake mounting configuration just need to space caliper alittle to center on rotor i could use Z06 6 pistons but just not economical for daily driving duty with brake pad replacement costs but do look nicer

i have to double check my measurments of but eyeing it look about little over 2"-3" between stock caliper and wheel face and 4"-5" to wheel drum and top of stock caliper but thats just eyeing i could be way off lol

Thanks You

And to OP sorry about the chatting here

here is my thread for anybody interested in buying your wheels should be helpfull has pics of clerance on fornt and rear

Zach/90\irocZ

iTrader: (6)

i agree 100% and couldnt have said it better than you... you can explain it better than me im only a Corpsman in the Navy lol

thats why i got wheel adapters to correct bolt pattern as like you said your on that line some people have failure others dont but it makes me sleep better at night running correct bolt pattern and your running a spacer anyways so why not !

Any information dealing with risk or danger is good info irregardless of how many times its repeated i greatlly appreciate your information greatly as i will accept your word over alot of people here call me a geek but i rather be safe

That sounds like a really interesting job.

Zach/90\irocZ

what tire size your going to use and spacer size you used ?
yea that would be hilarious i seen that to many times in japan its a reall lifstyle out there and in cali the hella flush scene as they say lol
it can be at times epecially when im station with the marines i have some funny stories and cool ones

275s all around.

Running a 1" spacer that adapts to the correct offset. This is the 2nd set of xxr wheels I have ran on a camaro.

Zach/90\irocZ

iTrader: (6)

275 all around should of got 285 lol i didnt like the tire stretch with the 275 on the 18x10 Budnik Wheels i used to have imo.... ive seen the other xxr wheels you had on the blue camaro pretty nice

get some pics up lol

paul_huryk

275 on a 10" is minimal if any tire stretch, actually it's the optimal size...

Zach/90\irocZ

iTrader: (6)

yes your correct .but some reason mines i had look stretch maybe due to tire brand as each tire are not exactly the same from brand to brand and if tire sidewall has rim protector etc it was a 40series tho idk

//<86TA>\\

iTrader: (14)

thats most likely what you saw. every brand of tire is slightly different in width, some are narrower others wider.

white_ghost

Dude, $250 is a great deal for a set of rims with tires mounted. But around me, you would have to pay a minimum $50 per adapter to convert and then you added spacers another $15 each, now you are at another $260. Where others worry about studs holding up over time, this is true. But what I have not seen discussed, is about a more common problem when using not only a adapter, but a spacer on top of it, and that is weight displacement. If you put the wheel weight far enough out away from the axle flange.......you can easily start bending the axle and wearing on bearings fast. If you keep those wheels you will have to look into beefing up your axles.
Good Luck.

The spacer is only on the front and thats so I could put the front wheels on so my neighbors would stop bitching. I've been waiting on my hubs for my C5 brake conversion which will push the wheels out enough that I will not need the spacer. I've run ALOT of diffrent wheels on thirdgens got most backspacings figured out, LOL.

I don't like adapters but it is cheaper as my CCW LM5s on my IROC cost $3300. I have about $350 in this wheel setup bolted to my car.

Damn how many third gen z28s do you have?? Lol. They look good, your old xxrs are on my 4th gen and looking purty. I like those that you have. put up some more pics. Oh ya need to camber that bish out. Thinking like -3, on a solid rear car. Yup!

Rims $250- decent digital camera $99! DUDE, lets see some better pics !

Its my phone camera and the flash isnt worth a **** so all I get is dark pics. Tires got changed to 275/35 in the front as the 225/40 really where not safe. I'll take pics after I install the C5 brakes today.

The front tire appears to be flat or way to narrow for wheel.

iTrader: (3)

The pics are still a bit dim. I'd like to see a footprint from behind or a front view. Doesn't look half bad! How's the turning radius?

Any clue what offset the rears are? Did you need a spacer?

Zach/90\irocZ

iTrader: (6)

what size are the rear looks like 40s in rear and 35s in the front or its just a illusion lol


they +25mm all around they do have 15mm offset now but i think those just been release...

you dont need a spacer for the rear you would need one for the front due to the hub max spacer in the rear that you can use is a 1in imo and you would be close to fender lip depending on how low you are if your stock height then there shouldnt be no issues for front i think a 1.25in max for front and tuck in nicely a 1.5 will probably work also

if anyone knows? what would be the LEAST amount of backspacing i could run on a 18x10" wheel up front without any rubbing issues
