Suspension Specification & Development
Correct suspension specification is not about choosing from a catalogue. It is about understanding the chassis, the driver, the tyre and the application — then building a system around that reality.
Why Specification Matters More Than Product
The suspension market is full of quality products. What is far less common is the knowledge to specify those products correctly for a given vehicle, driver and application. Spring rate, damper valving, motion ratio, tyre construction and chassis geometry all interact — and getting that interaction right is what separates a suspension system that genuinely works from one that simply fits.
Too Fast To Race approaches suspension from an engineering and chassis development perspective rather than a sales perspective. The starting point is always the application — what the vehicle is, how it will be used, what the driver expects, and what the chassis is actually capable of. The product follows from that analysis, not the other way around.
A consistent theme across every application we work on is the value of compliance and driveability over stiffness and aggression. A car that maintains tyre contact, rewards the driver with honest feedback and remains composed under real-world conditions — road or track — is faster than one that simply feels firm. Suspension that impresses in the car park frequently disappoints where it matters. We specify for performance that is real and measurable, not for a feeling that sounds right at a standstill.
Suspension Expertise & Applications
Fast Road Suspension
Road suspension demands a different philosophy to track suspension. Compliance, ride quality, tyre contact and real-world usability all matter. We specify fast road systems that genuinely improve chassis behaviour without sacrificing daily drivability.
Fast Road Suspension →Track Day Suspension
Track day use introduces G-loading, sustained cornering and thermal demands that expose the limitations of standard suspension quickly. Correct specification for track day use is about balance, consistency and predictability — not simply stiffness.
Track Day Suspension →Nürburgring Setup
The Nürburgring Nordschleife demands a suspension philosophy of its own. The combination of high-speed compression events, elevation changes and surface variation means a dedicated Nürburgring setup rarely resembles a conventional circuit setup.
Nürburgring Suspension →Nitron Suspension Systems
Nitron produce some of the finest road and track suspension systems available at their price point. We specify Nitron systems with bespoke spring rates and damping characteristics developed around real chassis testing rather than generic catalogue settings. Understanding the difference between Nitron R1 and R3 is the first step in choosing the right platform for your application.
Nitron Suspension →Penske Racing Shocks
Penske Racing Shocks represent a step into genuine motorsport-level damper technology. For applications demanding the highest levels of damping consistency, adjustability and data-supported development, Penske remains the benchmark.
Penske Racing Shocks →Nitron elec-TRON
Active electronic damping technology that adjusts continuously in real time. The elec-TRON system integrates with BMW EDC and Porsche PASM or runs standalone — resolving the compromise that every passive damper setup requires.
Nitron elec-TRON →Hillclimb Suspension
Hillclimb and sprint demand suspension that works from the first corner of the first run. Venue-specific specification, cold-lap consistency and mechanical grip — the disciplines that define fast hillclimb setup.
Hillclimb Suspension →Caterham Suspension
The Caterham chassis is one of the most rewarding platforms to develop suspension around — and one of the most commonly misspecified. We have extensive experience developing Caterham suspension across fast road, track day and race applications.
Caterham Expertise →The Specification Process
Every suspension enquiry begins with understanding the vehicle and the application in detail. Generic suspension recommendations — even from experienced sources — frequently miss the nuance that makes the difference between a system that works and one that genuinely transforms how a car behaves.
We consider chassis weight distribution, existing geometry, tyre package, intended usage frequency, driver feedback style and budget as part of the specification process. Where appropriate, spring rates and damping characteristics are specified to bespoke requirements rather than defaulting to standard catalogue configurations.
The result is a suspension system that has been thought through for the specific application — not one that has simply been selected from a fitment database.
Discuss Your ApplicationUnderstand the Application
Vehicle, driver, usage, tyre and chassis characteristics assessed before any product discussion.
Specify Around Reality
Spring rates and damping calibrated for real-world compliance and tyre contact — not for maximum stiffness. Performance comes from contact, not aggression.
Select the Right System
Product selected to suit the application — not the application forced to suit the product.
Refine Through Feedback
Driver feedback interpreted and translated into meaningful setup direction where ongoing development is required.
Chassis & Vehicle Expertise
Suspension specification applied to specific platforms — understanding the chassis characteristics that shape how each car should be set up.
Caterham
One of the most rewarding and most commonly misspecified lightweight platforms. Extensive Caterham development experience across fast road, track day and race applications.
Caterham Suspension →BMW
3 Series, M3 and M car platforms across all generations — E30 through G80. Rear-wheel drive chassis that reward correct specification and punish incorrect spring rate balance.
BMW Suspension →Porsche
911, Cayman, Boxster and GT platform variants. Rear-engined and mid-engined dynamics that demand platform-specific specification thinking.
Porsche Suspension →Lotus
Elise, Exige, Evora and Emira. Lightweight platforms where over-springing is endemic and correct specification produces transformative results.
Lotus Suspension →Mazda MX-5
All generations — NA through ND. Natural balance and light weight that rewards correct specification and suffers visibly from incorrect spring rates.
MX-5 Suspension →Toyota GR Yaris
Rally-derived AWD platform with genuine engineering intent. Suspension specification that accounts for GR-FOUR dynamics rather than applying rear-wheel drive thinking.
GR Yaris Suspension →Alpine A110
Lightweight mid-engined clarity of purpose. One of the most naturally gifted fast road and track day platforms — and one that responds beautifully to correct suspension development.
Alpine Suspension →TVR
Griffith, Chimaera, Cerbera, Tuscan and T350. Lightweight British sports cars that are substantially more capable than their reputation suggests when suspension is correctly set up.
