Alfaholics GTA-R Billet Front Upright Set

GTA-R/UPRS

We have developed these new CNC machined billet uprights to tackle the final remaining engineering flaw in the design of 105/115 series front suspension when used in a high performance application. What started off as a project to eliminate brake pad knock-back, has resulted in one of the single biggest improvements for performance 105 series driving…!Alfa designed the uprights with relatively small diameter spindles for mounting the front hub/disc assembly, which suited the standard wheel/tyre package the factory used. However, when these original uprights are used with modern tyres, the cars suffer from a long brake pedal after going through a series of corners (either on the 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 as “pad knock-back”. This occurs when the spindle flexes in the upright due to the loadings from the wheel/tyre, resulting in the disc being able move beyong its normal axis, thereby forcing 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 interface the upright in order to significantly increase rigidity.While redesigning the uprights, we also took the opportunity to address the pickup geometry of the upper and lower ball joints. With careful analysis and computer simulation of the KPI, scrub radius with our 7×15” 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 benefits of this redesign 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. The result you experience when you drive with these uprights is without doubt the single biggest improvement to the suspension of any performance 105 series car! Steering weight is transformed, making sticky trackday Yokahama AD08 tyres feel like 185 section road tyres at parking speeds, whilst there is less torque in the steering during oversteer corrections. The front of the car is now even more precise and better conveys the limit of adhesion through the steering to the driver.These uprights are designed in conjunction with our top specification GTA-R front suspension components in order to extract the very best out of the cars. That means they need to be fitted with our geometry kit and our titanium top wishbones. Due to the modified upper and lower pickup positions, these uprights must be used in conjunction with our steel angled quick steering arms (not our billet aluminium straight versions) in order to retain the correct bumpsteer geometry. These uprights have been optimised to fit with our 6-pot brake kit and have 1750/2000 (89mm) caliper bolt spacing. They can be used with other brakes that are compatible with 1750/2000 uprights although you may need to modify the disc offset.Supplied as a pair with a matching set of wheel bearings and hub oil seals to work with the 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 optimise your bumpsteer which are designed to be used with our steel quick steering arms and rose jointed track rod kit (available separately).

Alfaholics Billet Titanium Lower Wishbone Set

£5,995.00 GBP (ex vat)

GTAR/TI/WISH

CNC machined billet titanium wishbone arms with titanium 4-bolt version cross pins and titanium nyloc nuts – save an incredible 5kg over factory parts! We have designed these arms for direct fitment to all 105 series cars with 4-bolt version engine cross members. Cars with 2 bolt cross members can retro-fit these arms by modifying the cross member to later spec, as per the period Alfa technical bulletin. Dependant on your race series regulations, they can be used in conjunction with our lightweight spring pans or our fully adjustable 2 1/4″ conversion and with either a factory bottom ball joint or our geometry kit lower pickup. The arms use race type spherical bearings rather than the factory metallastic bush to ensure greater geometry precision. As fitted to all top specification Alfaholics GTA-R builds.
