Sourcing Custom Brake Rotors

Update by Per Schroeder to the LeGrand Mk 18 project car

The new rotors are dimensionally identical to the old pieces except for thickness.

With everything buttoned back up, there's not a lot of room between the inside edges of the caliper and the rotor.

The differential conversion on the rear of our LeGrand included a fresh single rear brake rotor, Carbotech pads and a new Wilwood caliper. That means that we needed to check over our two front rotors and change out the brake pads to match the rear.

At first glance, it appeared that everything was okay, but we soon realized that the rotors actually had a slight warp. This wasn’t just an uneven transfer layer—the rotors had been turned down at least four times and were quite thin. We searched around for replacements but came up empty-handed.

Enter Coleman Racing Products. They can reproduce unusual or custom rotors for very reasonable prices. We received a quote of around $65 apiece to recreate our rotors at their original thickness. While we were at it, we also had Coleman Racing cross drill the rotors to save some weight.

We topped off the new front rotors with a set of Carbotech AX6 pads to match the rear.

We’re on the home stretch of all of this work. We’re hoping—fingers crossed—that we’ll see the final uprights and axles by next week.

solid. 800lb autocrosser = not much heat.

Yeah but how much does the care weigh? Sorry man, couldn't resist.

Coleman Racing Products! Awesome. We've bought numberous things from them over the years. They can custom machine just about anything. The original owner (Gene) is a super nice guy.
