Professional Wiring Solutions
At Spec Motorsport Wiring, we refuse to compromise. Every harness is constructed using Tefzel M22759/32 wire. This cross-linked ETFE insulation offers superior abrasion resistance, flame retardation, and handles extreme temperatures while remaining lighter and thinner than standard automotive wire.
We protect our looms with Raychem DR-25 heat shrink. Originally designed for military defense, it provides the ultimate resistance against fuels, brake fluids, and high heat, ensuring your electronics survive the track.
