Two generations of TaylorMade's best driver technology — one made the carbon face mainstream, the other refined the inertia generator. Both are outstanding used buys. Here's how to choose.
The SIM2 and Stealth are separated by a single model year but represent meaningfully different design philosophies. The SIM2 pushed titanium face technology to its limit — Speed Injected Twist Face, 46g inertia generator, forged ring construction — and delivered one of the fastest titanium drivers TaylorMade ever made. The Stealth threw the rulebook out entirely and replaced the titanium face with a 60-layer carbon composite, saving 44g that was redistributed throughout the head. Both are outstanding on the used market. The question is which suits your game.
| Category | SIM2 (2021) | Stealth (2022) |
|---|---|---|
| Face Material | Speed Injected titanium | 60-layer carbon composite |
| Head Size | 460cc | 460cc |
| Ball Speed | Marginally higher on centre | Strong across the face |
| Forgiveness (MOI) | High (inertia generator) | Slightly higher (CG redistribution) |
| Launch Angle | Mid-high | Mid-high (lower CG) |
| Sound / Feel | Richer, more titanium-like | Slightly muted (carbon face) |
| Adjustability | Adjustable loft sleeve | Adjustable loft sleeve |
| Typical Used Price (UK) | £100–£145 | £110–£150 |
| Stock Shaft | Fujikura Ventus Blue | Fujikura Ventus Red |
In independent robot testing, the Stealth generates marginally more ball speed on off-centre strikes thanks to the weight savings from the carbon face being moved to improve CG position. On dead-centre contact, the SIM2's Speed Injected titanium face is every bit as fast — and some testers report fractionally higher peak ball speed.
In real-world play, the performance gap between these two drivers is small for most golfers. What you'll notice more is the sound: the SIM2 has the classic TaylorMade "crack" that many players love. The Stealth is slightly more muted — not unpleasant, but noticeably different. If sound matters to you, that's worth considering.
Both drivers are highly forgiving, but the Stealth edges it slightly. The 44g saved from replacing titanium with carbon was redistributed to lower and deepen the CG, which raises MOI and improves directional stability on heel and toe strikes. The SIM2's 46g inertia generator does similar work and is genuinely excellent — it's a close call, and the difference won't show up unless you're mishitting regularly.
At similar used prices — which is where these two often land — the Stealth is the better buy for most golfers. The carbon face technology represents a genuine innovation, the forgiveness is marginally better, and it's the newer generation. However, if you find the SIM2 at £20–£30 less, it remains a phenomenal driver that will match or beat the Stealth on a good strike. Don't overthink it: either driver will outperform most amateur golfers' ability to notice the difference.
Both drivers are widely available on UK eBay. When buying either, check the loft setting on the adjustable hosel is correct (9.5° or 10.5° suits most players), confirm the head is torqued down properly, and inspect the crown for paint chips — cosmetic on the SIM2, more visible on the Stealth's carbon crown. The stock Ventus shafts on both are genuinely good and worth keeping.
