Free UK mainland shipping on all orders over £200. All price includes VAT


New from SiCo-Developments is our new range of high quality performance brake discs - SD Performance! The aim is to maximise the performance of the discs but also keep them realistically priced to offer good value for money.

J Hook Discs are the latest disc face design by AP Racing. SD Performance have adapted the initial design onto OEM discs for the following reasons:
1.They give improved bite
2. For high temperature track day use they give better debris clearance and reduces distortion / vibration.

For road use we decided to opt for the version where the outer grooves do not run out to outside diameter but stay within the confines of the disc face. For road applications they also generate less noise than straight or curved groove discs and don’t suffer the fatigue cracking that drilled disc users can experience after many heat cycles. So win win for J hook.

We also take a non handed OEM casting and Left/Right the J Hook pattern to ensure temperature stability and an appropriately designed disc face for either the nearside or offside of the car to give a good gas path despite not using a handed casting. Where they really come into their own though is when theyre combined with a more capable set of brake pads - this is a real track day enabler and we find customers finding other weaker areas of their car such as tyres and suspension now that their car stops reliably again and again. J hook is the homologated disc face for BTCC and has been for three years.
