    I'm a new owner of a 365 GT 2+2 with BORRANI wheels with many questions, probably some of them pretty stupid. One of which is, are the spokes in these wheels chrome, steel, aluminum or something else? The reason I'm asking is I want to get the proper cleaner. Thanks. Gary

    If the wheels are original and have not been rebuilt, the spokes are chromed steel. Wheels can be rebuilt with either chromed steel spokes or stainless steel spokes. Check the spokes with a magnet to see what you have.

    Hi

    Borrani wheel need to be rebuilt by an official Borrani agent. We are the UK agent and we send the wheels back to Borrani in Milan Borrani

    The Spokes are either painted steel for the racing wheels or Chrome Steel. They are catagorically NOT stainless steel spokes.

    What year is the car. i think they should be RW 3812 7.00"X15 fitted with 205VR15 Pirelli Cinturato ™

    Regards

    As Dougal says, my 2008/2009/2014 wheels have steel chromed spokes.

    While Dougal works very hard to sell tires, unfortunately, his information is not always accurate. The correct Borrani wheel for the 365 GT 2+2 is a RW 4075 7 1/2 x 15. If you are located in the US, there are a number of private firms that rebuild the wheels with either chrome or stainless spokes.

    Stainless spokes are dangerous as they work harden! They should never be used with an alloy rim!

    Chroming the spokes makes them more brittle and therefore not suitable for the stresses placed on them from racing.

    Painted wheels are slightly lighter.

    Kare: It depends on the metalurgy of the stainless steel used in the spokes. Over the years, I have seen lots of broken spokes, and for street driving, stainless is usually OK. However, for race usage, we only use "bare" metal spokes and painted wheels. We have our spokes custom made and use a larger diameter spoke and nipple. Cork Adams does all our rebuilding.

    Curing hydrogen embrittlement is very easy to cure, but it is impossible to visually inspect the spoke if it is covered with a layer of chrome.

    Paint can hide cracks also. Some of the methods used to cure hydrogen embrittlement can actually weaken the steel itself.

    Austenitic stainless will work harden, no matter which grade you use. I think stainless might be OK for display or low miles but every 1000 miles will put the spokes through 800000 stress cycles, so very soon the spokes are something else that you opted for. Therefore I don't see much point in using stainless. For me that use of it just shows that the people involved don't really know their stuff.

    Larger diameter spokes might be a good solution if you want a stiffer rim. With modern tyres that sounds like the way to go.

    I had my wheels redone with chrome plated spokes and nipples, as original. This would be the correct treatment for a show car. For a driver, I'd prefer stainless spokes, stainless nipples. Aside from being maintenance free, the thing I like most about SS is that yellowish patina SS gets with age, it looks great.

    A negative about chrome is the unseen flaws that develop during assembly and tightening of the spokes, and this is something I learned from Cork. Over time, moisture can creep under hairline cracks and result in blemishes in the plating.

    OK it is not always 100% clear to me which model is which. I would suggest mixing one Ferrari Model up for another doesn't make you stupid or deserving of catty remarks

    However the correct Ferrari 365 GT 2+2 Wheel is RW3812 and the correct Ferrari 365 GT4 2+2 Wheels is RW4075


    Maybe i got my models mixed up, it could happen to anyone. the question is: is the car a 365GT 2+2 or a 365 GT4 2+2. The think the original request is for 365 GT 2+2.

    which; correct me if i'm wrong, fitted 205VR15 Pirelli Cinturato ™ CN72

    There is more imformation on my Borrani web site.

    Borrani wheels must not be rebuilt with stainless steel spokes. Personally i wouldn't buy any classic car wire wheels with stainless steel spokes, they worry me almost as much as tubeless wire wheels.

    Borrani wheels should be rebuilt by a Borrani agent. the Classiche Authenticity is in jeopardy without the correct wheels. weather Classiche authenticity is important to you or not is another question. but if you need to have your wheels rebuilt why not do it properly. here are some pictures of the Borrani Factory in action. I went there when Longstone first became their UK distributors. the build quality, particularly now, is excellent.

    is the car in question a 365 GT 2+2 or a 365 GT4 2+2?

    what year is the car in question?

    This is off the official Borrani web site:-

    CLASSIC WHEELS - Ruote Borrani
    Applications list
    Size Mounting Hub Spokes Type Wheel code
    FERRARI 365 GT 2+2 1968-1971
    7.0x15" Front-Rear 42 RC 72 Record RW3812
    If the wheel type you are searching for is not listed, please contact us. Many designs were specially developed for one-off or racing applications, and are guarded in the Borrani database of 8000 different applications.



    Borrani say the RW4075 is for the 365 GT4 2+2

    CLASSIC WHEELS - Ruote Borrani
    Applications list
    Size Mounting Hub Spokes Type Wheel code
    FERRARI 365 GT4 2+2 400 1972-1985

    If the wheel type you are searching for is not listed, please contact us. Many designs were specially developed for one-off or racing applications, and are guarded in the Borrani database of 8000 different applications.




    I will however fire the coment accross to Borrani in Milan and ask if there is any confusion with the wheel recomendation for this car

    Also on this Borrani web site they will show you your correct Borrani distributor DISTRIBUTORS - Ruote Borrani This is a link to the official Borrani agent in the US Borrani Americas is the north and south American dealer
