  • GTA-R Reservoir & Feedline Kit – Floor Pedal Boxes Only

Premium quality Alfaholics production! This kit is an adaptation of our hugely successful RHD dual circuit balance box, now designed to fit LHD 105 series cars with floor mounted pedals. As used on all our GTA-R builds. Box CNC machined from billet aircraft grade aluminium, giving a superb look to the kit!

This box replaces the standard Alfa-type brake master cylinder, whether it is a European single circuit or a USA dual circuit system. It bolts to the gearbox cross-member and is a simple installation. As shown in the photos, it fits perfectly and is tucked up neatly out of the way. It can also be used in conjunction with standard exhaust brackets and is compatible with the Alfaholics stainless steel sports exhaust system. This system is perfectly suited for both fast road and track day cars as well as full race cars

It uses a pair of high-quality Girling race brake master cylinders with an adjustable balance bar, allowing the front to rear brake bias to be adjusted. A remote bias adjuster cable can be screwed onto the end of the bar allowing the bias to be fine-tuned from the cockpit.

By using race master cylinders, we have been able to match the bore diameter of the cylinders to the calipers, thereby permitting the servos to be removed while also maintaining excellent braking power. By removing the servos, pedal feel is dramatically improved and it is easier to modulate the brake pressure and therefore minimise wheel locking under heavy braking. The kit is supplied with the optimum sized master cylinders depending on whether the car is fitted with Dunlop, ATE, 4 pot or 6 pot brakes.

A spherical joint is fitted in the front of the box where the pedal rod enters the box to ensure free movement of the actuation rod.

The balance box is supplied complete with master cylinders, banjos for hydraulic fittings, brake rod, balance bar, spherical bearing, lid and bolts.
