Fastrax 1/10 RC Car 95mm Spring Set Soft Blue Medium Red Hard Black FAST158-S

Overview

The Fastrax 1/10th 95mm Spring Set is an essential suspension tuning component for RC car enthusiasts across the UK who are looking to dial in their vehicle's handling characteristics. Whether you're a weekend basher, a competitive racer, or an RC hobbyist seeking to optimise your car's performance on different terrain, this versatile three-piece spring set gives you the flexibility to adjust your suspension setup precisely. Spring selection is one of the most critical tuning elements in RC car performance, directly affecting how your vehicle rides over bumps, maintains traction through corners, and responds to driver inputs on varied surfaces.

This Fastrax spring set is specifically engineered for 1/10th scale RC vehicles and features a 95mm length specification, making it compatible with a wide range of popular RC platforms and chassis designs. The inclusion of three different spring rates—soft, medium, and hard—means you can experiment with suspension geometry to find the perfect balance for your driving style, track conditions, or terrain preference. For anyone serious about RC car setup and tuning, having access to multiple spring rates is invaluable, allowing you to adapt quickly without needing to purchase individual springs separately.

Key Features

• Three-Piece Spring Set with Colour Coding — The set includes three springs with distinct colour identification: blue for soft, red for medium, and black for hard. This colour-coding system makes it easy to identify and organise your springs, streamlining the setup process and reducing confusion during tuning sessions. Quick identification means less time faffing about with springs and more time driving your RC car.
• 95mm Spring Length — The 95mm specification is a standard size for many 1/10th scale RC vehicles, including popular platforms from brands like Traxxas, Team Associated, Losi, and other manufacturers. This universal sizing ensures broad compatibility across multiple vehicle types and chassis designs, making this set a versatile addition to any RC tuning toolkit.
• Soft/Blue Spring Rate — The soft blue spring provides the lowest spring rate of the three, offering maximum suspension compliance and comfort over rough, bumpy terrain. Soft springs are ideal for bash sessions, off-road racing where absorption of big hits is paramount, or when you need maximum grip on loose surfaces where the chassis needs to follow the ground closely.
• Medium/Red Spring Rate — The medium red spring sits perfectly in the middle, offering a balanced compromise between compliance and support. This is an excellent all-purpose spring rate suitable for general driving, mixed terrain, and situations where you need predictable handling without excessive body roll or loss of control through cornering.
• Hard/Black Spring Rate — The hard black spring provides maximum support and resistance to compression, ideal for smooth tracks, high-speed driving, or situations where you need to minimise suspension travel and maintain a lower, more stable platform. Hard springs are excellent for on-road driving, fast off-road courses, or when running additional weight or larger shells.
• Fastrax Quality Manufacturing — Fastrax is a recognised and respected brand within the RC hobby community, known for producing reliable suspension components and upgrade parts that deliver consistent performance and durability across thousands of driving hours.

Technical Performance

Suspension tuning is where RC car performance truly comes alive, and the quality of your springs directly impacts how your vehicle handles across different driving conditions. The Fastrax 1/10th 95mm Spring Set represents a fundamental upgrade and tuning solution for any serious RC car UK enthusiast. Spring rates are measured in specific weight-per-millimetre compression values, and having access to three different rates allows you to systematically dial in your suspension to match your driving style, vehicle weight distribution, and the specific terrain you're tackling. Softer springs excel at absorbing impacts and maintaining consistent chassis attitude over rough ground, whilst harder springs resist compression more aggressively, keeping your vehicle's platform stable at speed and reducing excessive body roll during aggressive cornering. The engineering behind these springs ensures consistent performance characteristics across extended use, with material quality that withstands the punishment of repeated compression cycles without losing their designed characteristics. These springs are designed to work seamlessly with standard shock towers and suspension geometries found on 1/10th scale RC vehicles, making installation straightforward for anyone with basic RC car maintenance experience.

Frequently Asked Questions

• Which spring rate should I choose for my RC car? — Spring selection depends entirely on your driving style, vehicle setup, and terrain. Start with the medium red spring if you're unsure, as it provides balanced handling suitable for most situations. If your car feels too soft and bouncy, switch to the hard black spring. If it feels stiff and harsh over bumps, try the soft blue spring. The true benefit of this set is that you can experiment and find the perfect rate for your specific needs.
• Are these springs compatible with my 1/10th scale RC car? — The 95mm length specification is a standard size for most 1/10th scale vehicles, including popular platforms from Traxxas, Team Losi, Team Associated, and many others. However, verify your vehicle's current spring length before purchasing to ensure compatibility. If your car currently uses 95mm springs, these Fastrax springs will fit directly as a replacement or upgrade.
• What is the difference between soft, medium, and hard springs? — Soft springs (blue) compress more easily and provide better suspension compliance, making them ideal for rough terrain and bash sessions. Medium springs (red) offer balanced performance suitable for general driving and mixed conditions. Hard springs (black) resist compression more aggressively, keeping your chassis stable at speed and on smooth surfaces, and are preferred for on-road driving and competitive racing on prepared tracks.
• How do I know when to change springs? — If your RC car feels like it's wallowing or bouncing excessively after jumps, try the hard black spring. If the ride feels harsh and the chassis seems to ride high with poor ground contact, switch to the soft blue spring. Spring tuning is a hands-on process of experimentation, and having three rates available means you can quickly dial in the perfect setup for any conditions.
• Is this suitable for beginners? — Absolutely. Whilst suspension tuning might seem technical, changing springs is one of the simplest modifications any RC enthusiast can perform. This three-piece set is perfect for beginners who want to learn about suspension setup without needing to purchase multiple individual spring sets. It's an excellent educational tool for understanding how suspension affects vehicle behaviour.
• Can I use these springs on different vehicles? — If your other 1/10th scale RC vehicles also use 95mm springs, these can be swapped between them. This versatility makes the set even more valuable if you own multiple 1/10th cars or if you're experimenting with different platforms.
