Industry Focus
When development cycles run in hours not weeks, ISG delivers ultra-lightweight wire, sealed connectors and fire-protection sleeving under race-day lead times.
Motorsport operates at the absolute limits of interconnect engineering — and at a pace that most suppliers cannot match.
Formula 1, WEC, IndyCar and rally programmes build and rebuild harnesses on timescales measured in hours. Wire must be the lightest available. Connectors must be sealed against water, fuel and oil ingress. Fire protection must meet FIA requirements. And every component must be available from stock, today.
ISG has supplied the motorsport paddock for years. Our stock is aligned to what race engineers actually need: ultra-lightweight TXL and GXL wire, sealed circular connectors, fibre glass sleeving, self-amalgamating tape, heat-shrink boots and the full range of accessories that harness builders consume at race events.
Same-day despatch is not a premium option at ISG — it is our standard. When a team is building a new loom overnight before qualifying, we need to have it on their workbench as quickly as possible.
TXL and cross-linked ETFE wire constructions delivering the lowest possible harness weight without compromising current rating or flexibility.
Race-day and test-day emergencies serviced from in-depth UK stock — same-day despatch on all standard motorsport product lines.
IP67-rated sealed connectors with vibration-resistant terminal contacts for the extreme mechanical environment of racing powertrain and chassis systems.
FIA-compliant fire sleeving, ceramic-coated fibreglass and self-amalgamating tape protecting harnesses in proximity to exhaust and braking systems.
