Has anyone installed these? Im a goon and want to rev higher just because. Do other engine modifications need to be made to increase the rev limiter safely? What about performance gains under the rev limit. Just curious. Thanks.
Hey! Just wanted to clarify, we do not offer valves, just valve springs. When it comes to our valve springs, we specifically designed them for higher output 2.0 motors that had valve float due to weak exhaust valves, GLI and CC. These are not a necessity for the GTI.
Regardless, these are a great addition. They are lighter, stiffer, and have better durability than the stock valve springs. Because of these improvements, you will have increased stability and output of the motor.
We do not switch out or change the rev limit, just make sure you can get there :thumbup:
Hope that helps. Here is a link to the valve springs:
