Using our world championship winning T4 platform blended with our latest complete re-engineered T4'20 concept with central drivetrain, we worked with the XRAY R&D team on further improvements of our FWD concept. Based on the experiences gained in the previous racing season with the T4F we have built the all-new T4F'21 based on the all-new T4'20 platform making the T4F the highest-performing FWD electric touring car sharing the XRAY's commitment to engineering perfection, design, performance and support; all made possible by state-of-the-art in-house manufacturing.
- All-new FWD platform based on the T4’20
- All-new drivetrain layout with centralized motor position
- Central layshaft location for more consistent on-power/off-power balance
- All-new motor position in front of the layshaft for the improved weight balance for FWD class
- Super narrow top shaft utilizes new 20T pulleys and pressed-in ball bearings to minimize space requirements
- Narrow suspension holders and longer arms improve traction and corner speed
- All-new 7mm longer suspension arms feature two shock mounting locations; the lower position combined with ULP shock towers reduce chassis roll and improve stability in high traction conditions
- All-new super low anti-roll bar mounts and new compact linkage components helps lower the vehicle CG
- All-new redesigned anti-roll bar system features new front bars, smaller bushings and shorter ball joints designed for the new low CG mounting locations
- All-new symmetrical top deck shape provides clearance around new central drivetrain pieces while maintaining even side to side chassis flex characteristics
- All-new central motor mount positioned directly on chassis centerline for consistent chassis flex
- All-new black anodized lower bulkheads are moved 1mm inward to increase clearance for new long arm suspension geometry
- All-new narrowed upper clamps to match lower bulkheads and integrate with new shock towers
- All-new lighter graphite floating servo holder and taller servo posts redesigned to work with new suspension and driveline geometry
- Compatible with most T4’20 spares and option parts
