240SX Wheel Fitment Guide (S13 & S14) – Offset, Spacers & Fender Rolling Explained

Fitting the right wheels on a Nissan 240SX is part science, part art. Whether you’re aiming for aggressive stance, functional grip, or drift style, the key is understanding wheel offset, tire sizing, and how your suspension setup impacts fitment. This guide breaks down what works on both S13 and S14 chassis — with and without fender rolling or spacers.

Understanding Wheel Fitment Basics

• Width: Measured in inches (e.g., 8″, 9.5″)
• Offset (ET): The distance from hub to wheel centerline. Lower ET = more poke.
• Bolt Pattern: 4×114.3 (stock S13/S14) or 5×114.3 (after conversion)
• Hub Bore: 66.1mm (stock)

Stock Suspension Clearance – No Fender Rolling

S13 Fitment (No Roll, Stock Ride Height)

• 15×7 +20 to +25 – OEM fitment, zero issues
• 16×7 +25 – Flush with fender
• 17×8 +30 – Slightly tucked, great daily fit
• 17×9 +35 – May rub front on full lock

S14 Fitment (No Roll, Stock Ride Height)

• 16×7 +30 – Stock SE wheels
• 17×8 +35 – Perfect street setup
• 17×9 +38 – Needs 5mm spacer in front to clear strut

Fitment with Fender Rolling – Lowered Suspension

Lowering your 240SX changes everything. Most coils add camber and reduce inner clearance. Rolled fenders help avoid rubbing with wider setups.

S13 Aggressive Fitment (Rolled Front & Rear)

• 17×9 +20 – Ideal drift spec with 215/45
• 17×9.5 +12 – Needs stretched tire & camber (~-3 deg)
• 18×9.5 +15 – Flush/slight poke, tight fit

S14 Aggressive Fitment (Rolled Fenders)

• 17×9 +22 – Flush look, no rubbing with 225/45
• 18×9.5 +15 – Slight poke, needs -2 to -3 camber
• 18×10.5 +18 – Needs roll/pull, stretch, camber

When to Use Wheel Spacers

Wheel spacers help push wheels outward if offset is too high (ET+35 or more). They’re often used to avoid rubbing on coilovers or to match front and rear stance.

Recommended Spacer Sizes

• 5mm: Minor clearance gains for brake or coilover fitment
• 10mm: Levels out flushness, popular on front wheels
• 15-20mm: Use when running high offset wheels like +40 or OEM G35/350Z wheels

Important: Use extended studs with any spacer over 5mm.

Fender Rolling – When and Why

Rolling your fenders gives you extra clearance by flattening the inner lip of your fender. It’s a must if your tire is close to the edge, especially when lowering the car.

Signs You Need Fender Rolling

• Tire rubs under hard turns or bumps
• You’re running wide wheels with low offset
• You’re tucking tire and want full compression clearance

Tire Sizing Tips

Matching your tires to your wheels is key. Too wide = rub. Too stretched = unsafe. Here’s what works for daily/street setups:

• 17×9 = 215/45 or 225/45
• 18×9.5 = 225/40 or 235/40
• 18×10.5 = 245/35 (aggressive)

Conclusion – Choose Fitment That Matches Your Goal

The perfect 240SX wheel setup depends on your suspension, fender work, and intended use. Whether you’re building a clean daily, a slammed show car, or a track-ready drift machine — knowing your offsets and fitment options ensures no surprises (or fender rub!).

Helpful tools:

• Fender roller kit
• Wheel spacers (5mm to 20mm)
• Extended wheel studs
