Is the CAC-137 suitable for tuned gear ratios?

Yes, CAC-137 handles common tuning changes without needing custom machining, but check clearance with larger spur gears or unique differentials.

Does this require new bearings or hardware?

In most cases you can reuse existing bearings and pins, though replacing small hardware during an upgrade is a good opportunity to refresh worn parts.

How much difference will it make on lap times?

Improvements depend on driver and setup, but reducing drivetrain lash and improving stiffness with CAC-137 usually yields crisper corner exits and steadier lap times.

Any installation tips for first time upgraders?

Clean mating surfaces, lightly lubricate splines, and test fit at low throttle before full run to confirm there is no binding.
