Flywheel Design & Key Improvements

Our flywheel retains the same dimensions and weight (3.15kg) as the Porsche Motorsport flywheel MPN: 99710204191 / 997.102.041.91 / 997-102-041-91, made by ZF Sachs Racing with part number 003071.999566, but features several significant upgrades::

✅ One-Piece Design with Integral Ring Gear – Far more reliable than the Porsche Motorsport / Sachs Racing two-piece bolt-on ring gear system.
✅ High-Strength Forged Chromoly Steel (CrMo) – Special nitriding heat treatment provides a 60 HRC surface hardness (twice as hard as the OEM Porsche Motorsport flywheel).
✅ Enhanced Durability & Longevity – Greater resistance to wear, deformation, and heat-related fatigue.

Ancillaries

✅ Flywheel Grooved Ball Bearing – Equivalent to Porsche Motorsport PN: 93110211102. Included with the flywheel.
✅ Flywheel M10x1.25 Socket Head Screws, Grade 12.9 – Equivalent to Porsche Motorsport PN: 93010220600, but with a shorter head height for increased clearance with the bottom clutch disc. Must be ordered separately.

Applications

✅997 GT3 Cup 3.6L (2005-2009) also known as 997.1

✅ 997 GT3 Cup 3.8L (2010-) also known as 997.2

swift G13B flywheel

The flywheel is very light compared to the stock one. Overall it looks very good and it fits perfect with the oem clutch. The car is already very light (under 600kg) and it's a perfect match. It revs a lot quicker and the up shifts are very fast. The downshifts should be very precise with heel and toe most of the time. Overall I'm very happy.

The quality looks decent exactly as the pictures. The oem ring gear (95mm) fits snugly and overall seems very good. The gearbox is alredy assembled an soon I'll test it. Also the delivery was quick and the comunication with RSX was fine.

I am very satisfied, the quality is in the details, the phases are made everywhere, there is nothing sharp anywhere, also, at my request, they made a special adapter part for my gearbox, at this stage I am very satisfied
