When track testing our Project DC2 Acura, the limitations of the stock brakes quickly became an issue. Even though we had originally rebuilt the old worn stock brakes with Stoptech OEM replacement street performance slotted rotors and street performance brake pads, the brakes would fade away in just a few laps of hard track driving with the braking forces that our Nitto NT05 tires could produce. Hard track driving with larger modern tires was asking a bit much from simple stock sized higher performance street parts.
Since OEM replacement parts were not cutting it, we decided to get some serious help in the braking department from Stoptech. Since we decided that we wanted to run our original sized 15″ wheels we were handicapped for the size of the brake system that we could run. Often we run a large brake system so we can get away with a less aggressive brake pad so we won’t have to change pads back and forth for track days. With the 15″ wheel we are going to run as large of a brake as we can in the limited space. Will we be able to get away with a streetable pad on the track? We will see.
The kit used for our Integra is a Stoptech Trophy kit. Trophy kits are differentiated from standard Stoptech brake upgrades by their caliper which is CNC milled after forging to get rid an average of .7 lbs of material and the silver and gold hard anodized finish which is very hard giving good wear and corrosion resistance.
The Aerorotor is 290mm in diameter vs the stock 260mm, a significant size difference of 30mm. The Aerorotor is also lighter at 10.5 lbs vs the stock 10.75 lbs even though it is a much bigger part. The weight difference is due to the two-piece Aerorotors CNC machined 7075 aluminum hat which replaces the iron center of the stock rotor.
The Aerorotors friction ring vane geometry is designed using CFD to optimize their shape for best airflow through the rotor for good cooling. The rotors ID is fully machined for best balance.
