The HPI RS4 Sport 3 is back again, this time in the iconic BMW E30 with the Warsteiner livery, a tribute to Roberto Ravaglia's World Touring Car Championship triumph of 1987. This 1/10th scale replica captures the spirit of a champion, riding on the renowned Sport 3 chassis. Full-time 4WD, a sealed drivetrain, and waterproof electronics ensure unstoppable performance on any surface. Double wishbone suspension and adjustable shocks fine-tune your handling, while iconic BBS RS Mesh wheels clad in SPEC-GRIP tyres let you dominate corners and conquer straights.

The RS4 Sport 3's suspension boasts a race-proven double-wishbone design, mirroring the setup of modern race cars. Fine-tune anti-squat and anti-dive using standard pivot blocks, while optional parts offer control over sweep and toe angles. Achieve precise roll centre adjustments front and rear with vertical ball stud mounting on both inner and outer camber links. Multiple shock mounting positions ensure adaptability to various road conditions with a comprehensive range of shock suspension angles.

The RS4 Sport 3 boasts adjustable-height body mounts, allowing you to install any 1/10th scale touring car body from HPI Racing onto the chassis. Simply adjust the front and rear mounts to ensure proper clearance for the wheels and chassis components beneath the body. Body pins secure the mounts in place, while multiple mounting hole positions provide fine-tuned body fitment for a personalised look.

The rear hub features a vertical ball stud adjustment, enabling effortless rear roll centre customisation. Adjusting the ball stud height with optional spacers directly influences rear-end traction as the car navigates corners. Additionally, the suspension arm offers three distinct shock mounting holes for convenient shock angle fine-tuning.

HPI achieved exceptional handling in the RS4 Sport 3 by strategically positioning components as low as possible in the chassis. This design results in an ultra-low centre of gravity, significantly enhancing cornering performance.

In contrast to multipart plastic tub chassis prone to flex, the RS4 Sport 3's one-piece moulded chassis delivers exceptional rigidity and torsional stability. This translates to enhanced handling precision and responsiveness, giving you a competitive edge on the track.
