 The Nitrac rear discs I purchased in September ’08 for my Focus RS have performed brilliantly. They have managed a trip to the Nurburgring, a track day at Donington this new set will see a bit less ‘Hard’ use, but I’m sure will perform with the same dependability.

 I purchased a set in July last year - they have lasted extremely well covering 60,000miles - twice the life of the standard discs with better braking performance with a more aggressive pad!

 I drive a Toyota 4x4 and the nature of my job is that I do at least 50,000 miles per year. I had always used OEM Toyota discs and got around 30,000 miles out of them. I stumbled across Nitrac discs and have been delighted with the performance– I have now driven over 100,000 miles in the discs and they still do not require replacement, I cannot recommend Nitrac discs highly enough!

 I'm much pleased with NITRAC discs, so much I will send you a video as soon as I get the new set, they already have 50 000km and still very good condition.

 I bought a set of your discs and Yellowstuff pads for my Toyota Celica around eighteen months ago and have been very pleased with them, after some very hard driving the front disc grooves are nearly gone especially on the rear face, so may have to replace them soon, but the pads are less than a quarter worn! Thank-you for introducing me to Nitrac.

A key part of our series is endurance races – 2 hour non-stop races. We have never had a set of brake discs last an entire race, until we tried Nitrac – now we can last an entire race and have a clear edge.

Welcome to our website!
We strongly believe that NITRAC brake discs are the best standard fit discs on the European market. Each disc is is custom made to our stringent specifications in ISO 9001 certified European production facilities. Only top quality close grained pearlitic grey cast iron to BS EN 1561:1997 is used with rigorous quality control of all aspects of production (see Technical Information for more detail) . The finished discs are then put through a unique 4 day Deep Cryogenic Treatment (DCT) process developed through many years of race experience by Frozen Solid , Europe's leading Cryogenic Treatment specialists. DCT is an extension of normal heat treatment which alters the crystalline structure of the metal itself to produce a finer and more consistent grain structure throughout the component. This has many benefits including:
  • Vastly increased resistance to warping, cracking, scoring and flaking
  • Improved thermo dynamic properties delivering better braking performance and the virtual elimination of fade
  • Improved wear characteristics giving up to 3 times longer operational life and a very low cost per mile.
NITRAC discs are tough enough to withstand track day or even full competition use and to back these claims each set of NITRAC cryo-treated discs comes with a lifetime guarantee against all defects, which is not invalidated by track or competition use. ( Terms and conditions apply )

For the best in performance and safety, low costs and total peace of mind on both road and track, the choice has to be NITRAC.

Deep Cryogenic Treatment
Brake discs, as with all metal components, have to be heat treated to give them the strength and hardness required. Conventional heat treatments cycle components from room temperature to about 900ºC, but “room temperature” has no metallurgical significance. NITRAC uses processes at cryogenic temperatures (-195ºC) to give enormous improvements in strength and performance. For more detail see Technical information
