The idea was to race without resorting to wild tuning, that only distorts the technical merits of the original car. Remove the race numbers, slicks and roll cage, and the cars could easily be once more employed as road cars.
Those SZ Trophy racers have been officially homologized, can be found in the FIA Historic Database.
Strangly there can not be found a homologation form for the RZ !
The cost of a season's racing:
Here is a breakdown of costs involved in the 1993 SZ Trophy. This race series, backed by Zagato and organized by the Montecarlo group Monegasque Representatives, is composed of six races at principle Italian tracks, plus two international events:
1.) Alfa Romeo SZ coupe ( including 25% discount ) 60.000.000 Lires.
2.) Tuning kit: including shock-absorbers, springs, ( the hydraulic lift system used to raise the production car etc. was ditched ) free-flow exhaust,
reinforced clutch, brake system, engine management chip, heavy duty battery, balanced engine ( not lightened ) plus workmanship 25.000.000 Lires.
3.) Safety kit ( including roll-cage, 4-point racing harness, fire extinguisher system,
towing-hook ) 3.000.000 Lires.
4.) 12 16 inch 3 pieces OZ Racing Wheels 3.200.000 Lires.
5.) Pirelli racing slicks for 8 races 15.000.000 Lires.
6.) Mechanic for 8 races 40.000.000 Lires.
So the total of an SZ racing season will be: 146.200.000 Lires, but I think you had lots and lots of fun for that money !!!
The rumor goes that at these cars they have welded the orignal welds over again to make the cars invisibly stiffer.
Lighter windows in some cars would also have been used
Here some more trophy car pics:
Below some photos from SZ 103 ( VIN xxx3000137 ) driven by Sig. Gabriele Folco Zambelli, one of the Trophy race drivers in those days.
Another "special" was the yellow RZ ( roadster ) that was prepared for Montecarlo for Duilio Truffo to race. It was finished in a hurry and there was even not enough time to take off the catalyser and as the engine was brand new and hadn't been run in, it was running just 200 bhp. instead of the 220-230 of the other cars. It also had a distinct weight disadvantage ( of some 100 kg. ), but even so Truffo drove brilliantly to come third. Most of the race he was up the second SZ's exhaust pipe !
The black paint job on the yellow RZ has been designed by Ercole Spada.
It seems in the end 3 yellow RZ's have been produced ?
I hope someone can provide more information about this / those car(s), the races where it has been used, the driver ecc. In 2011 a trophy RZ was offered for sale in Japan.
This ( picture below ) is the Montecarlo car as described above.
This is the MARTIN DAWES version which was only made 2 times.
Modification:
Aragosta Suspension
Brembo 4Pod brake system
Aftermarket CPU chip
Aftermarket piston, cam shafts
Roll cage
Sparco seats
OZ racing alloys
Upgrade fuel tank
Aftermarket exhaust system
Air condition was removed.
