GTA-R Titanium Wheel Hub – Pair
£1,895.00 GBP (ex vat)
Set of beautifully CNC machined billet titanium wheel hubs for all cars with ‘late’ ATE brakes 1968 and onwards. They feature additional pocketing and a reduced diameter to save even further weight and represent an amazing 2.4kg weight saving per pair.

We have developed these new CNC machined billet uprights to tackle the last remaining engineering flaw in the design of 105/115 series front suspension when used in a high performance application. Alfa designed the uprights with relatively small diameter spindles for mounting the front hub/disc assemblies, which suited the standard wheel/tyre package the factory used. However, when these factory uprights are used with modern high grip tyres, owners all suffer from a long brake pedal after going through a series of corners (either on road or track) that require the brake pedal being pumped once to get the bite point back to the correct pedal height – this effect is known by performance drivers as “pad knock back”. This is caused by the thin spindle flexing in the upright from the loading and that causes the discs move and push the brake pads away from the discs, causing the long brake pedal. To tackle this issue we have completely redesigned the uprights using a larger diameter spindle and a more robust fitment area where they into the upright to give them additional support. Whilst redesigning the uprights and knowing we going to be machining from billet, it also gave us a blank canvas with regard to the pickup geometry of the upper and lower ball joints. With careful analysis and computer simulation of the KPI, scrub radius with our 7x15” GTA wheels, roll camber correction factor and roll centre height, we have modified the upper and lower ball joint locations to optimise all these important suspension kinematic factors. The nett result is handling with a faster transient response times in direction change, improved tyre temperature distribution across the tyre face, reduced tyre wear, reduced steering effort and reduced kick back from the steering in oversteer condition. These uprights are designed to be used with all our ultimate specification GTA-R front suspension components to get the very most out of the cars, so need to be used in conjunction with our geometry kit and our titanium top wishbones. Because of the modified upper and lower pickup positions, to retain correct bumpsteer geometry, these uprights must be used in conjunction with our steel angled quick steering arms, not our straight billet aluminium quick steering arms. These uprights have been optimised to fit with our 6-pot brake kit and have 1750/2000 (89mm) caliper bolt spacing, but can be used with other brakes that are compatible with 2000 uprights, however, you might have to make modifications for disc offset in the caliper. Supplied as a pair with a machining set of wheel bearings and hub oil seals to work in conjunction with your factory wheel hubs. Also supplied with a pair of short outer track rod taper pins and a range of spacer shims to allow you to measure & optimise your bumpsteer which are designed to be used with our steel quick steering arms and rose jointed track rod kit (available separately)

The outer front wheel bearing on 105 series cars is very small in design for its job. It is exposed to extreme temperatures and forces and usually needs re-packing every race. Until now, the wheel bearings available have not been good enough quality to last more than a couple of races. These premium branded kits, sourced by Alfaholics, are extremely high quality, thereby increasing the life of the bearings under race & track day conditions. Kit includes 1 inner, 1 outer bearing and a dust seal. As used in the Alfaholics 2.0 Sprint GT racer and Max’s GTA-R
