GFB Soft Spring for T9354 & T9360

This is the soft spring option for Go Fast Bits T9354 and T9360 wastegates. It's designed to allow for lower boost pressure settings than the standard spring that comes with the wastegate. Using a softer spring means your turbocharger's wastegate will start to open earlier, which helps to limit the maximum boost pressure the turbo can produce.

This spring is made from high-tensile spring steel, ensuring it maintains its tension and performance over time. It's a straightforward swap if you're looking to fine-tune your boost levels, especially on smaller turbo setups or engines where precise boost control at lower pressures is important. You'll want to use this if you're trying to achieve a specific, lower boost target that the stock spring can't achieve on its own.
