Adjustability, strength and ease of movement Review by Wesley

Cusco quality Review by Wesley
Easy install, makes a good difference
Noticeable Difference, Fast Shipping Review by Wesley
Ordered this and a few other Cusco items for my ER34. Easy install, great quality
Fast Shipping, Tein great for upgraded Ride quality Review by Wesley
Great Tein Quality, Fast Shipping, Very well packaged
Perfect for GTX Turbos, where the internal wastgate is too small. Review by Philipp
The quality is typically HKS perfect.The price-performance ratio is very good and there is no other option on the market where you can increase the spring preload. It would be nice if HKS would bring another 40mm version onto the market with a smaller housing. Because it's not that easy to accommodate such a large wastgate in the engine compartment.
