Lightbulb New AP Racing FORGED Radi-Cal Brake Systems!



AP Racing, the leading manufacturer of performance braking and clutch systems, for road and race use, has created a new range of Radi-CAL™ brake calipers, which incorporate race technology into high-performance road products. AP Racing's Radi-CAL racing calipers have taken the racing world by storm, dominating the highest level racing series on every continent.

The pressure forging process results in a strong, stiff caliper that is 20% lighter than similar cast calipers. Each caliper has been tested with over 500,000 cycles of pressure and torque to meet AP's stringent quality standard. The non-symmetric design is the result of Finite Element Analysis testing to determine where weight saving can be achieved without compromising strength and stiffness. Radi-CAL calipers are double sealed for durability. Hard anodized aluminum pistons are differentially sized to maximize pad life. A removable forged Bridge allows for easy pad changes. Anti-rattle springs prevent pad movement and knock back.

Available as six and four-pot front calipers, as well as a four-pot rear caliper, the new range of Radi-CAL™ products distil the company’s expertise in producing brake systems for race and OEM installations, into calipers suitable for the aftermarket. As a result Radi-CAL™ delivers an advanced brake upgrade for the owners of high performance and sportscars.

Featuring a two-piece aluminium body and h-piece, the forged non-symmetrical calipers offer a significant reduction in mass compared to conventional designs, and improved efficiency when resisting the torque generated by braking. This not only lowers a vehicle’s un-sprung weight, but also ensures continued high performance in demanding applications.

AP Racing’s advanced design process allows the concept to minimise structure and weight, while improving caliper cooling surface area, without sacrificing rigidity. This provides improved brake caliper cooling and reduces disc temperatures during high performance driving.

The Radi-CAL(tm) calipers feature a highly durable paint finish featuring the distinctive new Radi-CAL(tm) logo, and available separately or with matching performance road-car discs and pads for specific customer requests. The Radi-CAL(tm) Factory Big Brake kits incorporate floating two-piece disc assemblies, and include bespoke mounting bracket and bolts, a braided hose kit and DOT 5.1 high temperature brake fluid.




Includes
D701 Ferodo DS2500 Brake Pads
AP J Hook Rotors
Custom Goodridge SS Line
Optional AP Racing, Street, Semi Track, Track brake fluid.

I had heard about this from Stilen while working on my AP's. There may be a chance the new rotors will fit the older calipers, do data to confirm that. When are these brakes released for sale? They look awesome!

I can see how these would save weight with that design but look kind of ugly. Function before form though is best.

Has anyone test fitted these with Apex 18s? I doubt the 390 kit will fit under 18s, but just curious.

So what is the primary advantage over the standard kit? Would you even notice the difference over the standard kit?

Looks like a quality product from a quality brand but that name... Radi-cal? Very odd name that I don't associate with a quality product. It reminds me of an info-mercial name brand. Sham wow!

After seeing this at Sema and having AP explain everything the kit is better than the standard.

For those that are interested, we have the brake template for the 390 kit.
PM your email, and I can send it to you.

We are in the finalizing phase for the template of the 370, just need to confirm few things.

A good shot of the pads and caliper from another angle.
