Bravo wheels for sale

as I mentioned it before, the ratio of the holes to the bolt circle and the distance from the end of each of the 5 holes to the edge of the lip would be longer, thus the look would be off. Or if you enlarge the holes itself to compensate for the plus 2 fitmet, it would also be off. Thus having an exact look of the original in a bigger size is impossible. However, if you are okay with having some differences, but with a general simiarity,then it is possible.

Why dont u gys call mht and get them the make u gys copys in billet. expensive but the best choice for strength. then once they get the wheel diamaters in the cad computer they can make u exact replicas any size u want.

Do you know how much it is to machine a complete wheel out of billet?? Apart from the cost of billet itself, the machine time all cost. So instead of 2600 a set, you are looking at 8000 a piece.. or more. Only prototypes are made in billet by auto manufacturer for show cars. usually they get billed 20-30g a set of wheels... Not to mention, why would I need MHT, when there are many machine shops who can do it? MHT buys the hoops, buys from others the centers and cnc out the patterns, slaps on its name and sells the wheel. Besides, we are talking about a one piece wheel, not a hot rod wheel with a billet center and spun outers. Totally different ball game. So, for the sake of argument, to build a exact replica of the wheel, if using a solid billet, you would need a solid billet piece with 15.5 height, 12.75 in width so that you can have the machinist spend a couple of days working it down to the shape of the wheel? That is why cast wheels still exist in the market today. Because it is cheaper to build. But, with such a low production, even a set of cast wheel would end up to be around 2-3000. So, my guess is that the wheels will be cast instead of the forged mentioned for the replicas....

I totally under stand about price just a sugestion,.. cast wheels if not done properly usually slowly leak air. u seem to know your stuff but there is many factors in casting wheels that can go wrong to make them weak. on my countach i will be going to a bigger wheel when finished body work i used to race cars so ive seen some wierd things happen to cast wheels at high speed its your life. i would never by a set of cast wheels unless they were original lamborghini peices. casting is old technology they can come apart at high speeds if not properly done. i personaly will spend the extra and get them done out of billet. there is manafactures all over the country that can copy the wheels and make them any size u want. mht was just a generic sugestion. its worth the extra flow.

herck, there are various forms of casting. Depending on the type of casting, yields different results. Cast wheels usually if done by sand casting which is what low volume manufacturers use is cheapest and the least reliable. Usually those are the wheels that leak that crack and break. In the case of the bravo wheels, it will be a hell of alot of added expense to get all the contours that the wheel has. While I understand as the alternative, you would only buy o.e lamborghini pieces, keep in mind that the original bravo wheels were sandcasted as well and prone to cracking. That is why there is even this thread... So, the notion that only o.e casting is good is absolutely not true. It really depends on what type of casting is done and what type of quality control is done to ensure the absence of the situations you mentioned. Besides, the casting you mentioned would probably leak is usually the sandcasting method, which honestly is the most antiquated mehtod of casting....Keep in mind that majority of the cars utilize cast wheels. So, if your theory that they come apart are true, then surely we should be seeing wheel failure based accidents all over the place... But apparently, that is not the case. The reason being that casting wheel technology has come so far from the unreliable sandcasting days that even murcielagos still use cast wheels... Gallardos use cast wheels, porsche uses cast wheels, Ferrari uses cast wheels... Notable tuners like Brabus, AMG, Alpina all use cast wheels. These wheels are no more special in casting technology than casting for vw or toyota vehicles now... virtually all cast manufacturing throughout the world is now quality controlled by computers and monitored extensively. The cast wheels are runned through non stop fatigue testing, as well front impact and side impact testing. The wheels are also xrayed to ensure the lack of hairline cracks that can lead to leakage. All these process regardless of "brand" are virtually identical to each other. The problem with billet apart from the fact you'd be hard pressed to allocate such a big chunk of billet is the fact that being billet doesnt not guarantee the wheel wouldnt fail. The grain from a billet wheel is jsut as prone to leakage as regular cast material. But, the reason why you dont see that is because most billet wheels are two piece variety with spun rim sections that have been heat treated and additonally pressure formed to eliminate and minimize possibility of leaks. That is why you dont see one piec billet wheels all over the place, too expensive and simlar in strength vs. modern casting technology. So, hopefully this information would shed some light on why one piece full billet wheels might not necessarily be the economical / performance practical or even the failsafe way to go. When you do have the billet wheels machined out though please show us pics of it as I am sure countach owners would want an alternative somwhat replica of stock wheels that also can be bigger sized and at an astronomical price and not necessarily tested out to o.e standards like modern casted wheels. =D> :partyman:

I totaly undertsand your point all manafacturers have cast wheel made from usually a outside manafacturer that specialise in that field.

my friend works in the plant in quensburough new westminister canada. that makes honda wheels. we had talks about failure rates that come from castings they throw wheel back into the foundry becuase of poroseness all the time. they have specialised equipment for checking runout and a bunch of other flaws that can happen in the casting process all my point was if u wanted to make different sizes of wheels in that style getting a couple of the original wheels maped and installed in a cad u could manafacture different size wheels that are exact.and a lot of wheel customiser today have tripple axise machine out there that can do anything u want out of a solid chunk or slice of aluminum. if u gys decide to purchase wheels i hope they are full checked before u run them at high speeds thats all. i personally like billet better for strength i have had aftermarket cast wheels that i have sent back rims becuase of the inner air leaking slowly through the porouse material. i dont know who the company u gys will be buying from but hoppfully he has all the machinery to check for flaws thats all. the best to all. :heart:

herck, I understand your point completely on the potential problems of casting and to take heed on who is doing the wheels. My personal opinion of the billet wheels is that the aluminum blocks are also essentially somewhat extruded , but at the same time still has issues of porosity. That is why 2 piece billet wheels are more popular and you see less of one piece billet wheels. it is easier to make and cheaper to make and more reliable. To spend extra on billet thinking it is added strength is not correct. It is only when you want something uniquely different from others that you would resort to milling out billet. The benefits of billet are minimal over a well casted product. The wheels in question here they mentioned are forged pieces. And if it is indeed true at 2600 dollars is a steal. But, my best guess is that the wheels are just cast pieces. It doesnt make sense to make a forged wheel when the weight savings is very little in the sizes for the countach. And indeed if it is a cast wheel, then yes you need to make sure all testing are done and proven and shown to consumers before they purchase. The typical wheel standards are JWL, TUV, or DOT standards. However, the most prevalent and satisfactory standard that is sufficient for wheels is JWL. Which is japan's wheel standard. They are minimal cost to certify yet are close enough in areas critical in relation to structural integrity of th wheel.

My 2 cents:

 

1- IMO there is NO F_CKING WAY they can make forged wheels for $2600 with such low production numbers.

 

2- Why do we keep beating a dead horse here? Forged or Cast you cant build a set of wheels for $2600 (anyone want to bet?) with such a small production run.

 

3- Here is the most realistic and economically feasable way to solve the CT wheel problem, build a 3 piece wheel (with hidden bolts/studs to preserve the original look) with off the shelf halves using a billet center that duplicates the original 15" Countach wheel. Considering that the center will be billet and rather easy to build it could be done for a reasonable price and you could give people the option of the later wheel look or the bravo wheel look.

 

If someone else had stated this before then my appologies, it just makes SENSE!

abolfaz, cast wheels can be made at 2600 per set. no problem. I know of people who can do it for me If they got the originals within a week, they can have wheels by August. :mrgreen: I just never wanted to deal with the trouble of trying to get bravo samples. I just want to see if the forged wheel thing can be done because I know it is just impossible. But cast? YES! very possible.

With any level of quality? Good enough for you to put on your car or Kit Car quality? The cast replica wheels that I've seen need an additional 8 to 10 hours of work each to get the finish right.

Better quality than the originals. We know the cast quality of the original bravos are BAD. It is porous and rough. The new cast ones can have great quality. Usually, once a sample is made, the quality determination and tolerances can be decided. But, usually there are no issues. The wheels are all xrayed to double check. If it was built, I have no issues with putting them on my countach.... So, in answering your question. Way better than kit car. Most kit car wheels are really really half**s in my opinion... I am talking about similar to modern o.e quality here.... But, its too much trouble to hunt down originals to work with ....

Okay, but what would be the point in producing a replica 15" wheel? What about my modular idea?

its already been done... the cost for casting a center piece vs. a full cast wheel are very minimal. The only reason a modular is if you want to fit that center on various cars and that is done already. The thing would be to produce an identical wheel that is better but with the authenticity of the original. Going with a modular doesnt make the car look original... Notice that a modular you are going to have a lip section versus no lip section from the original. Most ct owners probably dont want that.... I myself like the concave feature from the original wheels better.

Okay, then what size do you suggest making? Do you have pics of the modular wheel using centers that look like the originals?

Its on lamborghini registry under the for sale section. but unfortunately it is only 17-18 inch sizes. I would rather do the stock 15 bravos... identical to the originals. Any three piece or modular wheels tend to make the wheels smaller than it is. Look at the 25th wheels that were 15s, dont they look smaller than the later type bravos?

Those are $hit kit car wheels! I'm talking about an exact copy of the 15" center with hidden studs/bolts with halves painted to match the centers. They would look stock.

NO EXACT REPOS

 

 

Stand in line, and wait for the real thing

Abolfaz, not possible to have the contour of the original and have it as a modular. Unless ralph wants to lend his rims for about two months, then it is possible to replicate exactly....

No problem lending out the 89 rims

I honeslty don't care for the look of the bravo wheels, I was refering to using the centers from the later wheels.

if so, why not just make an exact replica of the later wheels. cost is same...Why do a modular set up?

I thought what we were talking about was something other than a 15" wheel?

yes. we are. 17 inch one piece. No need to do modular...

Check this out . I know its a Jalpa, but look at the wheels, the rears don't seem to fit right, could he be using countch wheels?

 

Nice wing huh? :vom:

No those are Silhouette wheels, they are only 1 inch smaller than the Countach.

 

Countach wheels have different off sets and wont fit the car.

 

That wing is :vom:
