When tuning high-performance go karts and parts for optimal front-end geometry, the Righetti Ridolfi 4mm Metric Wheel Spacer (17mm ID) delivers the exact track width adjustment needed for razor-sharp turn-in and unyielding reliability. Engineered to withstand the extreme lateral loads of competitive racing, this spacer (measuring an actual 5mm in width) provides a rock-solid mating surface between your wheel hub and spindle. It eliminates the vague handling and wheel deflection that plague inferior setups, allowing you to attack high-speed apexes with absolute confidence.
Precision Tuning Beyond the Engine Carburettor
A winning chassis setup demands the same meticulous attention to detail as tuning your engine carburettor or installing comprehensive engine rebuilding kits. Every millimeter of track width directly impacts your kart's scrub radius, jacking effect, and overall grip levels. By utilizing this 17mm ID metric spacer, racers can execute micro-adjustments to the front track, shifting the weight transfer characteristics to cure mid-corner understeer or stabilize corner-entry oversteer. Constructed from high-density, crush-resistant materials, it guarantees that your wheel fitment remains perfectly square, lap after grueling lap.
Durability That Matches Your Brake Calliper Parts
Just as you rely on premium brake calliper parts to haul your chassis down from top speed, your wheel spacers must endure immense compressive forces without deforming. This 4mm/5mm metric spacer is machined to exacting tolerances, ensuring a seamless slide over 17mm international stub axles. Whether you are fine-tuning a high-horsepower shifter kart or maximizing the momentum of a spec class setup running a fresh lo206 carburetor kit, this spacer maintains structural integrity under heavy braking and aggressive curb strikes. It simplifies pit lane adjustments, allowing mechanics to rapidly swap widths during frantic practice sessions.

Frequently Asked Questions
Q: Why is this listed as a 4mm spacer if it measures 5mm?
A: While commonly referred to as a 4mm spacer in karting terminology, the actual physical width is 5mm. This is a standard industry naming convention, but please account for the 5mm measurement when calculating your total front-end track width.
Q: Is this spacer compatible with all kart stub axles?
A: Yes, this spacer features a 17mm inner diameter, which is the standard size for international karting stub axles. It is designed to slide on easily without binding.
Q: How do I use these spacers to tune my kart's handling?
A: You can use these spacers to adjust your front track width. Increasing the track width generally increases front-end grip and can help reduce mid-corner understeer, while decreasing the width can help stabilize the kart if it feels too aggressive or "darty" on corner entry.
Q: Do I need to replace these spacers frequently?
A: These are constructed from high-density, crush-resistant material designed to withstand extreme lateral loads. However, you should inspect them periodically for signs of cracking or deformation, especially after heavy curb strikes or if you notice your wheel fitment is no longer square.
Q: Can I stack multiple spacers on one side?
A: Yes, you can stack spacers to achieve your desired track width. Ensure that you have enough thread engagement on your stub axle to safely secure the wheel nut after adding additional spacers.
