Hi Spec 300mm R114-4 Conversion kits

HI Spec R114-4 300mm 2 piece racing brake conversion kits are a fantastic way of increasing your braking performance at an affordable price. The R114-4 caliper has proved itsself to be a caliper of outstanding performance. This is combined with the ability to fit a massive 280mm disc in a 13" wheel. Hi Spec brakes are manufacturered in the UK and are hand made for each customer to your exact specification. We can provide this with a vast range of colours, disc styles and pad types. HI Spec Motorsport have been established for years and have won many engineering awards for their products.

All the Hi Spec racing brake kits in this section feature:

1 Piece 300mm/32mm discs
R114-4 anodised black racing calipers
Hardware and brackets for specific vehicles

We strongly recommend upgrade the front brakes on your vehicle before looking at other braking solutions or rear kits. A high percentage of the stopping power is achieved through the front brakes and should be more powerful than the the rear brakes. The size of the caliper requiered will also depend on the size and the weight of the vehicle they are being fitted to.
