Fiat – MTS Technik Suspension Kits

Fiat Cinquecento/Seicento – compact cars with big character on MTS Technik kits

Fiat – MTS Technik Suspension Kits provide full sport suspension solutions tailored to the lightweight Cinquecento and Seicento platforms. MTS Technik Suspension Lowering Kits pair lowering springs with sport shock absorbers so that reduced ride height translates directly into sharper handling, not just a more aggressive stance. Available drop ranges of 20–40/20–40, 50–70/30–50 and 60/40 mm can transform these city cars into genuine “go-kart feel” machines while still remaining road-legal and practical when configured sensibly.

Compared with stock suspensions, MTS Technik assemblies deliver a much firmer, more controlled ride, helping the Cinquecento and Seicento bodies roll far less in corners and under hard braking. As the manufacturer notes, the sport suspension is intended to reduce unsightly ground clearance and arch gap while keeping a workable compromise between stiffness and comfort. A 2-year warranty with no mileage limit and detailed application data confirm that each kit is developed for specific engine and year combinations rather than being a generic “cut spring” solution.

Technical Basics

MTS Technik sport suspension kits use high-quality chromium–silicon steel springs, cold-wound and protected by chemical treatments and durable powder-coat finishes. These springs are designed to maintain their rate and appearance over time despite exposure to road grime and weather. Shortened sport dampers are tuned specifically for the reduced travel and higher spring rates, providing firm yet controlled behaviour instead of the harsh, crashy feel often associated with mismatched lowering springs on OE shocks.

For the Cinquecento and Seicento, MTS offers several lowering ranges: moderate 20–40/20–40 mm drops aimed at fast-road use and more radical 50–70/30–50 and 60/40 mm options for a very low stance. Product descriptions emphasise that cooperation between springs and dampers dramatically improves the quality of the setup, reducing body roll from braking, acceleration and tight turns while keeping the car responsive and predictable. This is especially noticeable on short-wheelbase cars like these, which react strongly to any change in chassis behaviour.

Engine choice and axle loads are also important. A light 0.7 engine imposes very different demands compared with a 1.1 Sporting model, so MTS application tables list compatible engines, years and load limits alongside each part number. This ensures that spring and damper rates suit the actual weight on each axle, keeping the final ride height and handling within the intended window and avoiding under- or over-sprung setups.

Selection Criteria

To choose the right MTS Technik suspension kit for a Cinquecento or Seicento, start by identifying the car precisely: model, engine size and production year. Always select part numbers according to the manufacturer’s application list, because different engines and trims can produce significantly different axle loads. Incorrect selection can result in the car sitting too high or too low and in damping behaviour that does not match the published specifications.

Next, decide how much lowering you really need. A 20–40/20–40 mm drop tends to be ideal for daily-driven cars, giving a clearly sportier look and firmer feel while preserving usable travel for rougher roads. The more extreme 50–70/30–50 and 60/40 mm options deliver a very low stance and a noticeably sharper, “track-style” character, but also increase the risk of bottoming out, rubbing and underbody contact on poor surfaces. Consider your local road conditions, speed bumps and driveways honestly before opting for the most dramatic drop.

Wheel and tyre setup can make or break a project on these small Fiats. Wider tyres, lower offsets or spacers all push the wheel closer to fender lips and liners, especially when combined with large drops. When fine-tuning ride height, check clearance at full steering lock and through full suspension travel with realistic loads – driver, passengers and luggage. For a road car, it is usually safer to leave a few extra millimetres of clearance than to sit extremely low and risk constant rubbing and damage.

Installation & Maintenance

Even on small Fiats, installing MTS Technik suspension kits demands proper tools and experience, so using a professional workshop is strongly recommended. Replacing springs and dampers requires safe use of spring compressors, correct support of suspension components and torqueing all fasteners to manufacturer specifications. During installation it is prudent to inspect top mounts, bearings, dust boots and bump stops, replacing worn items so that new components operate in a refreshed environment.

After fitting the kit, a four-wheel alignment is mandatory, as even modest lowering alters toe and camber. For the first few hundred kilometres, it is sensible to drive a little more gently while springs and bushings settle, then re-check bolt torques and alignment. Long-term maintenance involves regular visual checks for damper oil leaks, chipped spring paint, cracked dust boots and wear in ball joints or bushings. Hard driving and occasional track use increase the load on the chassis, so periodic inspections are essential to keep the car safe and enjoyable.

FAQ

How much will an MTS Technik kit lower my Fiat?
Depending on the chosen application, Cinquecento/Seicento Suspension Lowering Kits offer ranges such as 20–40/20–40, 50–70/30–50 and 60/40 mm. Always check the specific product page for the exact drop figures for your engine and year.

Is the ride too harsh for daily driving?
MTS Technik sport suspension is firmer than stock but is designed around a stiffness/comfort compromise. For everyday use, the milder 20–40 mm drops are generally comfortable enough, while the more aggressive kits are better suited to owners who prioritise stance and handling over refinement.

Do I really need the full kit or just springs?
While springs alone can work for very small drops, MTS clearly recommends pairing lowering springs with shortened sport dampers for best results. The complete kit provides superior control, safety and durability compared with using lowering springs on standard shocks.

Is a wheel alignment necessary after installation?
Yes. Any significant lowering changes toe and camber, so a four-wheel alignment is essential following installation. Skipping this step can cause unstable handling and very rapid, uneven tyre wear.

How often should I inspect my MTS Technik suspension?
It is wise to have the full suspension system inspected at least annually, or more often if you drive hard or attend track days. Watch for new noises, oil traces on dampers or changes in ride behaviour and have issues checked without delay.
