New Magnesium wheels for Pantera GR4 and GT4
For all those who, like myself, race(d) De Tomaso Pantera
GR4 factory cars or replicas, or even GR4/GT4 tribute street cars,
it has been an nightmare to find the original Campagnolo rims that
were used in period for the factory cars (1972) . As a solution,
many of us use 13’’ rear wheels ( from street GT5 or GT5-S) at the
rear but those also are almost impossible to find, and are one inch
too small compared to the real factory 14-inch magnesium GR4 wheels.
The 14’’ wheels also do a better job filling out the fenders without
requiring spacers. Additionally, being in magnesium alloy, if they
were not cared for properly, those original wheels may have become
porous or even dangerous : they might crack and break because of
oxidation, magnesium wheels’ worst enemy.
bankrupt a long time ago. The only remaining solution was to buy
original wheels from people who wanted to get rid of them, or,
alternatively, BBS, Gotti or other non factory wheels. Those wheels
also, are very scarce, and expensive, and don’t come on the market
I have investigated for many years, the possibility
of having new magnesium wheels reproduced without any success, up to
very recently. I have now been able to identify a foundry in Italy,
Marvic Wheels SRL (http://www.marvic.it/en ) which has agreed to
reproduce the original Gr4 wheels ! This foundry has been producing
race wheels since 1954. They also produce and sell high-quality
castings for companies like BBS ( magnesium centers) , Dallara (
Formula Indy, Formula 3000 and GP2) and Oak Racing (2013 WEC , LMP2
The moulds are being created
at present, and the first batch will be released early march 2014, i.e. a little less than two months from now, just before the racing
Technical characteristics : Dimensions
are the exact reproduction of the original wheels, used on factory
group 4 cars in period : in fact, the foundry has had access to the
original Campagnolo drawings, and double-checked with my « Candy
car » original wheels . For the front : 10x 15, and for the rear
14x15. These wheels will fit factory GR4 or GT4, factory GR4
tributes, GT5 and GT5-S Panteras. Sand cast in AZ91 magnesium alloy
– the best there is for racing - and using same original
dimensions/thickness and so on . They come complete, ready to bolt
on, completely heat treated for strength, with a surface treatment
against oxidation, quality checks, machining, steel bushings inserts
for the wheel lugs and painted original silver or gold. Weight per
wheel is expected to be as follows : front 6.9 kilos ( 15.18 Lbs) ,
and rear 7.8 kilos ( 17.16 Lbs). There will be one major improvement
compared to period wheels : they will have, inside the rim, a slight
marking to prevent tyres to rotate on the rim when cold and at a low
tyre pressure ( a thing I have experienced with my own wheels at Le
Mans Classic, destroying a brand new slick tyre in the free practice
The wheels carry no « Campagnolo » marking.
They will carry the foundry’s mark, but on the inside of the rim,
making it therefore very hard to identify from the outside of the
car, whether it is a « Campagnolo » period rim, or a new rim.
Technical data of the batch production shall be engraved in each
wheel for further control if need be.
The pricing ex-factory
(Italy) is as follows : Euro 1500 per front wheel, and Euro 1800 per
rear wheel, i. e. a complete set for Euro 6600 + VAT (where
applicable) . Buyers outside of Europe do not pay VAT in Europe, but
they will be liable to import duties and local taxes in their home
countries. Shipping costs are on top of above mentioned prices.
Delivery will start in March 2014. After that, subsequent batches
will be per 10 wheels only, at the same price. Wheels can be ordered
separately, front and/or rear
Down payment invoicing and balance
shall be done directly by the foundry to the final customers. I am
in charge of the marketing and follow up, on an exclusive basis.
Payment conditions are as follows : 40 % upon ordering, with the
balance due when the wheels are ready for shipment. In agreement
with the foundry, I will coordinate the whole process and keep all
buyers informed in a timely manner.
See you soon, with state of
the art, brand new magnesium tribute wheels !
