シムレーシング用ペダルアクセサリー：スプリング・エラストマー・プレート解説

Quick Answer

Buy pedal accessories in this order: a stiffer brake elastomer or spring first, then a wider or grippier face plate, then fine-tuning hardware like travel limiters and dead-zone spacers. Match the accessory to your pedal's actual mechanism — load cell, Hall effect, or potentiometer — because a spring kit meant for a load cell brake can feel wrong on a travel-based pedal. If you are still on a basic two-pedal set, put the money toward a proper three-pedal set before buying tuning parts.

Most sim racers upgrade their pedals by replacing the whole set. That is expensive and often unnecessary. Springs, elastomers, and face plates are the three accessories that change how a pedal feels, and they cost far less than a new pedal set. The trick is knowing which one your pedals actually need.

This guide explains what each accessory does, how to tell whether your pedals will accept it, and when the money is better spent elsewhere. It covers load cell pedal accessories, pedal tuning accessories, and the fit questions that decide whether a part works on your rig at all.

What Each Pedal Accessory Actually Changes

Springs set the initial resistance and return speed. A softer spring makes the first part of the travel easier to modulate; a stiffer spring gives more resistance early but can make trail braking harder if your leg is not used to it. Springs are cheap and reversible, which makes them the safest first experiment on a throttle or clutch pedal.

Elastomers are the compressible bushings used on load cell brakes. They change how the pedal firms up as you press. A harder elastomer compresses less for the same force, so you reach your brake pressure sooner and with less travel. A softer one gives more travel and a more progressive build. Neither is better — it depends on whether you want a short, firm brake or a longer, more gradual one.

Face plates change the contact surface. A wider plate spreads pressure across more of your foot, which helps with consistency during long stints. A narrower or curved plate can suit heel-and-toe work. Grip material matters too: smooth metal is fine with shoes, but barefoot or sock drivers usually want a textured or rubberized surface.

• Change one thing at a time so you can feel what actually helped.
• Keep the original springs and elastomers in a labeled bag — you will want them back.

Match the Accessory to Your Pedal Mechanism

Load cell pedals measure force, not travel. On these, elastomers and spring preload are the main tuning tools, and a stiffer stack usually gives more repeatable braking because your leg learns one pressure point instead of a moving position. If your pedals use a load cell, prioritize elastomer kits and brake-face plates over throttle springs.

Hall effect and potentiometer pedals measure position. On these, springs and travel limiters matter more, because the pedal's output is tied to how far it moves. A stiffer spring on a position-based brake can make the pedal feel firm without changing the actual braking curve much, which is why some drivers are disappointed after fitting one.

If you are unsure which type you have, check the product page or the pedal's manual. If the manufacturer does not state the sensor type, treat that as a limitation and avoid buying mechanism-specific tuning parts until you confirm it.

• Load cell brake: elastomers first, springs second.
• Hall effect or potentiometer pedals: springs and travel limiters first.

Fit Guidance: Will It Actually Bolt On?

Pedal accessories are not universal. Spring diameter, free length, and wire thickness vary between brands, and an elastomer that is a few millimeters too wide will bind inside the housing. Before buying, measure the old part with calipers — outer diameter, inner diameter, and length — and compare those numbers to the listing. If the listing does not give dimensions, ask before ordering.

Face plates mount differently across pedal sets. Some use two bolts, some use four, and bolt spacing is rarely listed in a standard format. The safest approach is to buy plates made for your specific pedal model, or plates that use a slotted mounting pattern wide enough to cover your existing holes.

For pedal sets sold as complete bundles, tuning parts are usually model-specific. That is one advantage of buying a matched set: the manufacturer has already done the fit work, and accessories are listed for that exact model.

• Measure the old spring or elastomer before ordering a replacement.
• Slotted face plates fit more pedal models than fixed-hole plates.

Where Pedal Accessories Fit in Your Upgrade Order

If your rig still flexes under braking, fix that first. A stiffer pedal plate on a flexing mount will not feel stiffer — the movement just moves to the mount. Sort out the mounting and the seat position before spending on tuning parts, because both change how much force you can apply consistently.

After that, the highest-value pedal upgrade is usually a better brake mechanism, not a spring. A load cell brake gives you a repeatable pressure reference that springs alone cannot. Once you have that, elastomers and face plates are the cheap refinements that make it comfortable.

For drivers on a basic two-pedal set, a three-pedal set with a load cell brake is a bigger step than any accessory. Bundles that pair pedals with a shifter are worth considering if you also want manual gear control, because they often cost less than buying the parts separately.

• Fix mount flex before buying tuning parts.
• Load cell brake first, then elastomers, then face plates.

Decision Rules for Buying Pedal Accessories

• If your brake is a load cell: Buy an elastomer kit before springs. Choose a harder elastomer if you want a shorter, firmer brake, and a softer one if you want more travel and a more gradual build. One elastomer change is usually enough to find your preferred feel.
• If your pedals use Hall effect or potentiometer sensors: Focus on springs and travel limiters, because output is tied to pedal position. A stiffer spring changes resistance more than it changes the braking curve. Do not expect a spring swap to transform a position-based brake.
• If you cannot find dimensions for the part: Measure your existing spring or elastomer with calipers and compare. If the listing still does not confirm fit, do not order — a binding elastomer can damage the pedal housing. No dimensions means no purchase until you confirm.
• If your rig flexes under braking: Fix the mount, pedal plate, or seat position first. Tuning parts cannot compensate for a cockpit that moves when you press the brake. Rigidity before refinement.
• If you are still on a two-pedal set: Put the budget toward a three-pedal set with a load cell brake instead of accessories. The mechanism change matters more than any spring or plate. Upgrade the pedal, then tune it.

Products That Show These Principles

• Simagic P1000-3 Pedal Set & DS-8X Shifter Bundle: The P1000-3 is a three-pedal set with a 100kg load cell on the brake and Hall effect sensors on the throttle and clutch, with adjustable layout, height, stroke, travel, angle, resistance, and dead zones. The bundle also includes the DS-8X dual-mode shifter. A load cell brake plus built-in adjustability means you can tune feel with the pedal's own settings before buying separate springs or elastomers. The Hall effect throttle and clutch respond to travel, so spring changes there have a predictable effect.
• VNM Simulation Complete Control Bundle – Shifter, Handbrake V1.5 & 3-Pedal Set: The bundle combines the VNM Shifter with H-pattern manual or sequential modes, the VNM Handbrake V1.5, and the VNM Sim Racing 3-Pedal Set. Buying a matched pedal, shifter, and handbrake set removes the fit guesswork that comes with mixing brands. It also gives you one system to tune rather than three separate mounting and accessory puzzles.
• TR-One V3 Front-Mount Wheel Kit for Asetek Direct Drive Wheelbases: The TR One V3 2-Way Base Kit is a patent-pending front-mount wheel mount for Asetek direct drive wheelbases, designed for cockpit ergonomics and long-term flexibility. Pedal feel depends on the whole rig staying still. A rigid front-mount wheelbase setup keeps your upper body stable, so the force you apply to the pedals is consistent instead of being absorbed by flex elsewhere.

Who Should Buy Pedal Accessories

Best for

• Drivers who already have a load cell or Hall effect pedal set and want to fine-tune brake feel
• Sim racers who want a grippier or wider face plate for consistency during long stints
• Anyone who wants to experiment with pedal feel without replacing the whole pedal set

Not for

• Drivers on a basic two-pedal set with no load cell brake — a three-pedal set is the better first purchase
• Anyone whose rig still flexes under braking — fix the mount and seat position first
• Buyers who cannot confirm spring or elastomer dimensions for their specific pedal model

Start with the one accessory that matches your pedal mechanism, measure before you buy, and change one thing at a time. Springs, elastomers, and plates are cheap ways to make good pedals feel right — but they work best on a rig that is already stiff and a pedal set that already has a proper brake.
