RacingDiffs LSD conversion set review

When it comes to the world of Limited Slip Differential (LSD) conversion kits, two names often dominate the conversation: RacingDiffs and Phantom Grip. But which one truly offers the best bang for your buck?

In a recent podcast episode hosted at the RacingDiffs studio, we were joined by the esteemed Goran Jevtic, a former drift competitor and highly-respected drift judge. We dove deep into the technicalities and advantages of RacingDiffs over Phantom Grip. Here's what you need to know:

1. Performance Difference

The first and perhaps the most critical aspect we delved into was performance. Through careful measurements, it was evident that the RacingDiffs LSD kit springs are a whopping 10 times stiffer than those in Phantom Grip. This translates to a more reliable and robust grip on the road, ensuring optimum performance.

But the differences don't end there. RacingDiffs employs a ramp angle design in its LSD conversion, a principle adopted by some of the most advanced LSDs in the market, including the renowned ZF brand. This design innovation ensures smoother transitions and superior traction, enhancing the overall driving experience.

2. Durability

Durability is paramount when investing in any car part. And in this realm, RacingDiffs excels yet again. In a head-to-head comparison, the hardness of RacingDiffs plates overshadowed that of Phantom Grip, suggesting a longer lifespan and lesser wear and tear.

Moreover, RacingDiffs introduced a game-changing feature that addresses metal shredding, a common issue in LSDs. This solution? Friction discs placed strategically between spider gears and pressure plates. This design tweak minimizes internal damage, prolonging the differential's lifespan.

3. Easy Installation

Ease of installation can be the difference between a weekend project and a lengthy garage ordeal. Recognizing this, RacingDiffs provides a special set for each differential type, simplifying fitment considerably. In contrast, Phantom Grip's 'universal' kit for all BMW models requires gear grinding to ensure a snug fit, complicating the process for many DIY enthusiasts.

In conclusion, while Phantom Grip may come at a lower price point, the advantages offered by RacingDiffs in terms of performance, durability, and easy installation make it a worthy investment, justifying the price difference.

For those passionate about their rides and unwilling to compromise on quality, RacingDiffs emerges as the clear winner.
