Cooling

Bespoke aluminium fabricated cooling system with taper flow top tanks, motorsport grade water and oil cooler cores incorporating ECU controlled cooling fans.

Features

Our philosophy has always been to produce the very best components possible.

Whether the improvements are increased strength, reduced weight or improved geometry, we always use the highest grade raw materials for our Alfaholics-R parts and components, often replacing old fashioned materials with modern equivalents.

Our extensive and ongoing research programme combines modern technology with our heritage knowledge to create improvements in design and innovations in technology. These are installed on our workshop GTA-R 290, track tested at Nurburgring for optimisation and undergo thousands of road miles before sign off.

Suspension

Re-engineered with fully optimised geometry & improved design, our suspension systems deliver the highest level of grip and handling balance, whilst retaining the unique character and feel of a 105 series Alfa Romeo.

Exhaust

A dyno developed exhaust manifold benefiting from decades of experience on the race track to optimise torque and power delivery, paired to a refined 2 silencer system. Silencer design engineered to maximise performance and sound levels both in acceleration and in gentle cruise environment.

Gearbox

From gear ratios, to gear selectors and synchromesh components, we have fully re-engineered the Alfa gearbox to optimise all details; the rev drop between each gear to maximise performance and the quality and feel of the shift.

AXle

Alfa’s famous live axle, completely re-engineered. Featuring an advanced limited slip diff to maximise traction and feel at the limit of traction, titanium axle tubes to minimise weight and optimise tyre camber & toe geometry, billet diff sump for improved oil capacity & cooling.

Titanium front wishbones

Lower wishbones CNC machined from billet titanium featuring spherical bearings for superior accuracy of geometry under high cornering loadings. Upper wishbones fabricated from tubular titanium resulting in a further 6kg weight reduction.

Titanium uprights and hubs

CNC machined billet uprights with modified pick up positions to optimise dynamic geometry and uprated spindle design to eradicate pad “knock back”. Together with titanium wheel hubs and titanium wheel studs and nuts, a considerable saving of 3kg of unsprung and rotational weight.

Aluminium T-bar

Aluminium T-bar features redesigned chassis mount bushes and spherical bearing axle location for improved traction and further weight saving.

Double adjustable aluminium gas dampers

Developed by Alfaholics at the Nurburgring, these aluminium bodied double adjustable dampers provide exceptional body control and ride refinement with separate bump and rebound adjustment for the perfect setup on both road and track.

Titanium rear trailing arms

Significant reduction in unsprung weight and to increase rigidity improving rear axle location and damper control.

Brakes

Billet aerospace grade aluminium calipers. 6 piston front with 300mm vented carbon ceramic rotors, 2 piston rear with 280mm carbon ceramic rotors.

Aluminium dual circuit non-assisted pedal box for maximum pedal feel and adjustable bias front to rear.

Interior

Bespoke hand crafted leather interior. Fully insulated using Dynamat for optimum heat protection and noise damping.

Dashboard

Finished in the finest quality woven Italian leather and Alcantara for unparalleled aesthetics and anti glare properties.

Steering wheel

360mm Momo Prototipo steering wheel, Alcantara trimmed with petrol blue feature stitch.

custom weave & stitch detail

Leather and linen weave seat centres, Blu Benzina feature stitched rollcage and seats.

Carpets

Tailored in the finest English Wilton wool and bound in leather for the ultimate in luxury.

wheels & Tyres

Alfaholics designed lightweight alloy 8×15″ wheels, fitted with Yokohama high performance classic tyres and retained with titanium wheel nuts and studs.
