How do I know these kits fit my HPI Racing RS4 Pro 4 & Hara Edition 1/10 Touring Car (#185, #187)?
Each kit on this page is made specifically for the HPI Racing RS4 Pro 4 & Hara Edition 1/10 Touring Car (#185, #187). We cross-check scale, chassis layout and hardware locations against the factory manual so you get the right stainless screws and bearings for this exact RC model—no measuring or guessing.
What's included in the stainless screw kit for HPI Racing RS4 Pro 4 & Hara Edition 1/10 Touring Car (#185, #187)?
Every RCScrewZ stainless steel screw kit for HPI Racing RS4 Pro 4 & Hara Edition 1/10 Touring Car (#185, #187) includes a model-specific mix of socket head, button head, flat head and set screws, plus matching nuts and washers—with extras of the most commonly used sizes. Each kit also comes with Bondhus short arm hex wrenches in the sizes used on your kit and a durable plastic pit case you can reuse for storage and organizing hardware. Exact counts and sizes vary by model. The kit does not include electronics, shocks, motors or engines, or plastic parts.
Which bearings are best for on-road use with HPI Racing RS4 Pro 4 & Hara Edition 1/10 Touring Car (#185, #187)?
If you run your HPI Racing RS4 Pro 4 & Hara Edition 1/10 Touring Car (#185, #187) mostly on clean pavement or prepared on-road tracks, metal-shielded bearings are usually the best choice. They roll with lower drag for more speed and longer run times. Rubber-Shielded sealed bearings add extra protection against dust and splash but have slightly more drag, so they are better if you see mixed or light off-road use instead of pure on-road racing.
