GTA-R Parts Packages

Full set of Alfaholics production super lightweight carbon fibre bonnet, bootlid and doors, as used on all Alfaholics GTA-R 290 car builds. Bonnet versions available for both step-front and late GT, please select correct version for your application from drop down list.

Please note that the doors are made to the later improved wire lifter mechanism design to save further weight over the heavy and inefficient early scissor lifters. If your car has early scissor lifters then you need our parts number GLA020 x2 and GLA155 x4 to convert your car to late lifter mechanisms to be compatible with these doors.

We recommend converting away from traditional GT door seals to a knock on door seal (similar to Saloon/Spider), the lightweight doors do not have the required inertia to shut a stiff factory type door seal. Moving to a knock on door seal will result in Spider (and dare we say Porsche!) quality door shut. We have bespoke made a special extrusion to get exactly the profile size and foam construction we want for our GTA-R builds and have this available to purchase as an add on to your door order.

Following on from the huge success of our billet GTA-R uprights for narrow body 105 Alfa, we have developed a new set designed specifically to address the significant front steering geometry issues that widebody 105 series cars suffer from. We all love the look of a widebody GTAm type car, but the driving experience never lived up to the looks, with nasty tramlining and excessive kickback in the steering. This issue is caused by the excessive scrub radius of the steering/suspension geometry that results from the heavily offset wheels being used with standard factory KPI which was of course never designed for wide offset wheels. With the recent commissioning of a widebody GTA-R build for a customer, we chose this time to address this well-known issue with a redesign on our GTA-R upright, adjusting the KPI to significantly reduce scrub radius down to narrow body levels. Road testing this first GTA-R has proven a remarkable change in the characteristics of the steering; for the first time a widebody car drives precisely, with razor sharp steering response and an ability to carry speed with total confidence over heavily cambered and rutted surfaces, exactly as well as a narrow body GTA-R.

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 titanium 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 must also be fitted with our 6-pot brake kit.

Naturally to make these widebody geometry changes, we have had to make certain components of the titanium geometry kit and the 6-pot brake kit to a different design than our ‘normal’ parts to be compatible with the new upright geometry. If buying these uprights as a standalone item and not as a full GTA-R 290 Ultraleggera Titanium Suspension package, we will need to add additional components on top of this upright kit dependant on what Alfaholics suspension parts you might already have – in this case email us with what you already have and we will work a custom package for your individual application.

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 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 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).
