The best, smartest GT4 lip kit on the market.

Inexpensive Alibaba replicas are commonly available. On its own, that has kept me at bay of introducing a GT4 style lip kit - until now.

The new GT4-K lip kit intends to be a premium GT4 style lip with a keen focus on fitment and durability.

In this Series, I document the development of the GT4-K lip kit, its features, modularity, fitment and overall impressions.

Cheers,
