Wheels and wheel race parts for 105 Series Alfa Romeo

Manufactured exclusively for Alfaholics by the UK’s leading motorsport magnesium wheel manufacturer. This wheel has been manufactured to the very highest standards and designed with meticulous attention to detail, in order to ensure that it is an exact copy of the original 1st series Campagnolo wheel.

Particular attention was paid to the accuracy of the vent hole – the main aesthetic feature. The wheel has been cast using the latest motorsport spec magnesium alloy, developed for Formula 3 racing and as a result weighs a mere 5.3kg, 0.2kg lighter than the original Alfa wheel!
 
The wheels are finished in a protective black chromate coating, ready to be painted in the customer’s choice of colour. They are machined to the correct ET29 offset for 1600 & 1300 GTA and accept our GTA wheel badge and circlip. The wheels feature steel stud inserts (important for magnesium wheels) and are supplied with GTA centre badges and circlips.

Exclusive to Alfaholics and manufactured to the very highest standards, this wheel is an exact copy of the original 1st series Campagnolo wheel.
Particular attention was paid to the accuracy of the vent hole profile – the main aesthetic feature of the wheel. It is the design of the vent hole which is incorrect on all other current reproductions of the 15″ TI Super wheel (including Tecnomagnesio).

The wheel is available in 5″ and 5.5″ versions, we can also special order them in 4.5 as original – all of which are homologated sizes for race TI Supers.

The wheels are finished in a protective black chromate coating, ready to be painted in the customer’s choice of colour.

Following the success of our existing magnesium wheel productions, we have now manufactured these superb 13″ magnesium 1300 GTA/GTAm wheels, available in 3 different widths – 8″, 9″ & 10″. We used new old stock original Campagnolo wheels in each size as patterns to ensure perfect accuracy of detail, paying particular attention to the shape of the holes.  It is the profile of the holes which is incorrect on other reproduction 13″ wheels.

They have been cast using the latest motorsport spec magnesium alloy (developed for Formula 3 racing) and consequently are very light!  They are finished in a protective black chromate coating, ready to be painted.  The wheels also feature steel stud inserts and tyre retaining beads which are an added safety feature not present on original GTAm wheels.

Following the success of our existing magnesium wheel productions, we have now manufactured these superb Tipo 33 Wheels available to order as a full set. They have been cast using the latest motorsport spec magnesium alloy (developed for Formula 3 racing) and consequently are very light!

Cast using our GTAm wheel tooling and specifically machined to Tipo 33 104 PCD & hub centres with ET 15 front offset and ET 0 rear offset, 9×13” front and 10×13” rear. The wheels also feature steel stud inserts and tyre retaining beads which are an added safety feature not present on the original.

The wheels are finished in a protective black chromate coating, ready to be painted in the customer’s choice of colour.

Superb reproduction of the 6 x 14″ GTA Strada wheel with correct period look vent holes. The wheel is incredibly light at 5.8kg and comes complete with a GTA centre cap & clip.

The wheels carry a certificate from German TÜV who is performing the toughest wheel tests in the world.

A new uprated version of our 7×15″ GTA Veloce wheel. Featuring steel racing stud inserts and painted in our unique smoke grey finish.

These wheels allow fitment of modern high performance tyres such as the fantastic Yokohama AD08RS and Michelin Primacy.

The wheel is very light at just 7.0kgs. This has been achieved in part by incorporating small ribs into the back of the wheel, much like the original sixties Campagnolo design.

This allows the wheel to be made thinner in cross-section enhancing the aesthetics of the wheel, by making the holes appear finer and more elegant.

All variants of the wheels are now heat-treated for maximum strength and weight saving.

Our best selling wheel, now improved and even lighter!

The ultimate GTA style aluminium wheel, made exclusively for Alfaholics.

The last few years have seen the withdrawal of performance 14 inch road tyres from the market, with the result that there is little point spending good money upgrading your suspension, engine and brakes if you cannot transmit this improved performance properly to the road! Our GTA Veloce 7×15 inch wheels allow the fitment of modern high performance tyres such as the fantastic Yokohama AD08RS and Michelin Primacy 4, as fitted to Alfaholics works GTA-R builds.

The wheel is very light at just 7.0kgs. This has been achieved in part by incorporating small ribs into the back of the wheel, very much like the original sixties Campagnolo design, which allow the wheel to be made thinner in cross-section. The beauty of this thin cross section is that it has also enhanced the aesthetics of the wheel, by making the holes appear finer and more elegant. All variants of the wheels are now heat-treated for maximum strength and weight saving.

By being 15” diameter, there is adequate clearance for the steering ball joints (even without the use of GTA steering arms), so we have been able to produce the wheel to Alfa’s original design offset of ET29. We have also made an ET35 offset variant of the wheel, in order to clear the tighter rear arches on pre-1968 coupes (with the deeper rear arch) and all Giulia saloons. This means that we can offer a beautiful, lightweight 15 inch GTA style wheel to fit any 105 series Alfa Romeo.

The wheel is supplied with a GTA centre cap and circlip.

Suggested tyre sizes are 185/60, 185/65 or 195/60 for fast road use, 195/55 for high performance road and track day use.

An 8×15” version of the original 13” GTAm wheel.

Alfa Romeo, Ford and other manufacturers racing in the 1970s, made widebody versions of their race cars in order to fit wider tyres in an attempt to improve grip and therefore competitiveness. Tyre designs at the time were very antiquated compared with the compounds and constructions we have today, so the only option in the 70’s was to make tyres ever wider. Race tyres of the period were all huge in diameter which made it necessary to use 13” wheels in order to fit the wheel wells and retain sensible gearing. This inevitably meant compromising on brake disc size and limiting the scope to improve suspension geometry but this was considered secondary to the benefits of using a wider tyre.

Fast forward to the 21st century and vast improvements in tyre design and compounds mean that ultra wide tyres are no longer necessary and, in fact, can often be detrimental if the chassis is unable to work the tyre up to its operating temperature. 13” wheels have also fallen out of fashion with modern car design and consequently good 13” tyres are very hard to find. The only choice in 13” is to use either a modern semi-slick race tyre or a period high profile Dunlop CR65 race tyre. Semi-slicks offer good grip but the small overall wheel/tyre diameter causes serious ground clearance issues for road/trackday use. Increasing the ride height merely results in a ‘skateboard’ appearance. The alternative is to fit period race tyres but they are not legal for road use and their cross-ply construction makes the car vague and track cambers badly, not to mention being terrible in the wet! So, it raises the question; why spend lots of money and effort creating a lovely GTAm look but suffer appalling compromises and difficulties with a 13” wheel & tyre combination?

Well, the perfect solution is now here! You can have a stunning GTAm look wheel but in 15” diameter to suit high performance modern road and race tyres. The larger diameter also allows the use of our 4-pot and 6-pot brake conversions, neither of which are possible with a 13” rim. It also permits the use of the Alfaholics Geometry Kit which gives a significant improvement to the handling characteristics.

We have spent a lot of time and effort with 3D CAD programming perfecting the shape of this wheel, especially the oval hole design, to ensure that it accurately replicates the original wheel, rather than the incorrectly shaped holes of reproduction 13” wheels.

NOTE: These wheels will not fit cars with standard bodywork!

Yokohamas new tyre is based on the carcass of their all conquering AO48 semi slick race tyre, featuring a superb new compound and tread design for fast road and track use. We have tested this new tyre for several thousand miles on Max’s GTA-R and Andrew’s Ti Super-R with outstanding and completely unrivalled results. Tyre grip & traction is superb with beautiful progressive feel to slides, lovely steering feel & response and excellent ride quality. The wet weather performance is just as impressive, easily handling standing water at up to 90mph/145kph! As an added bonus, wear rate is surprisingly low! By far the best tyres we have used for cross-over road & track use; all the performance of a semi-slick, with wet weather practicality and safety of a road tyre!
