- 1st Gen (2001-2005). This section is focused on IS300 / Altezza-style chassis buyers
with the strongest drivetrain catalog coverage. Manual-transmission IS300 owners
should pay close attention to clutch, flywheel, shifter, and differential bushing options.

Quick Drivetrain & Transmission Buying Guide

Clutch Kits: Best for manual-transmission cars that need more holding power, a
replacement clutch, or a setup matched to engine upgrades.

Flywheels: Best for manual cars when refreshing the clutch system or improving
engine response. Lightweight flywheels can make the car feel more responsive but may
add drivability tradeoffs.

Limited Slip Differentials / LSD: Best for rear-wheel-drive performance builds that
need better traction, more predictable rotation, and stronger corner-exit grip.

Differential Bushings & Mounts: Best for reducing drivetrain movement, rear-end
clunk, and vague power delivery. These are strong add-ons for older chassis and
performance cars.

Differential Drop Kits: Best for lifted GX/LX/off-road platforms where front
driveline angles need correction.

Shifters & Transmission Accessories: Best for improving manual shift feel or
supporting a transmission refresh.

Service / Rebuild Parts: Best for older vehicles, high-mileage vehicles, off-road
builds, and restoration projects where reliability is the priority.


Quick Recommendations

Best manual-transmission refresh: Clutch kit + flywheel + proper fluid service
Best performance manual setup: Upgraded clutch + lightweight flywheel + short
shifter
Best rear-wheel-drive handling upgrade: Limited slip differential + differential
bushings
Best older chassis upgrade: Differential bushings, mounts, and service parts
Best off-road drivetrain support: Differential drop kit where applicable
Best quote-based approach: Email sales@modinjapan.com with VIN, year, trim,
drivetrain, and intended use
