Front-end alignment controls how your kart turns, how the tyres wear, and how much effort is needed at the wheel. Small changes to camber, caster, and toe can transform handling. Using laser aligners is the most accurate way to set this up.

Preparation

Remove front tyres
- Most karts use a 22mm lock nut on the stub axle. Loosen and remove to take the wheels off.
Fit the laser aligners
- Place them directly on the stub axle or on the wheel spacers.
- Make sure the bubble level is centred → lasers point dead straight.
Centralise the steering wheel (⚠️ most important step)
- Methods:
  - Place a ruler under the steering shaft and eyeball both sides.
  - Use a sheet of paper or clear plastic between the lasers → dots must line up in the centre.
- Once centred, lock the wheel (with a locking device or multi-grips).

Adjustments

Loosen Kingpin Assembly
- Use appropriate tools (e.g., 5/6/7mm T-bar + 13/17mm spanner for OTK).
- Just loosen — don’t remove — to allow camber/caster adjustment.
Adjusting Camber
- Negative camber (top tilted inwards) = more grip in corners, sharper turn-in, faster tyre heat.
- Positive camber (top tilted outwards) = more straight speed, cooler tyres, looser front.
- Adjuster direction:
  - Outwards = negative camber.
  - Inwards = positive camber.
- ⚠️ Don’t worry if the adjuster marks aren’t perfectly symmetrical — what matters is that the laser alignment is equal.
Adjusting Toe
- Keep steering wheel locked straight.
- Undo both tie-rod ends (10mm + 13mm spanners).
- Rotate tie rods to set toe:
  - Toe out (wheels outward) = sharper turn-in, better in wet.
  - Toe in (wheels inward) = more straight stability.
  - Neutral toe = least rolling resistance, fastest straights.
- Re-tighten carefully, holding tie rods to avoid “losing” toe when bolts twist.
Adjusting Caster
Caster systems differ by kart brand:
- Kart Republic / Parolin / CRG: Adjust by winding a 10mm bolt to shift kingpin forward/back.
- OTK: Replace with offset adjusters (kingpin must be removed).
- Arrow: Rotate top and bottom adjusters after loosening.
Effects:
- More caster = more front grip, more wheel lift, heavier steering.
- Less caster = lighter steering, more straight speed, less wheel lift.

Key Reminders

Always place aligners the same way on both sides (with or without spacers).
Steering wheel must be centralised → otherwise alignment will be off on track.
Tie rods shift slightly when tightening → hold firmly.
Focus on laser readings, not adjuster marks.

Quick Reference

Camber:
- Increase = more negative → more corner grip, faster tyre heat.
- Decrease = more positive → more straight speed, cooler tyres.
Toe:
- Increase = more toe out → sharper turn-in, tyre wear.
- Decrease = more toe in → straight stability, slower turn-in.
Caster:
- Increase = more front grip + wheel lift, heavy steering.
- Decrease = light steering + straight speed.

✅ Key Takeaway

Front-end alignment is precise work. Centralise the steering first, then adjust one setting at a time. Small changes (1–2mm, one “click” on adjusters) make big handling differences.
