Welcome back
In this video i install upgraded valve springs and test drive the car to compare before and after valve spring upgrade.
Car is 2006 535d touring stage 2 mods
This is a great upgrade and most overlooked when M57 is pushed past 350-400 bhp as Stock valve springs are very under rated for that job.
I have filmed in detail complete process of disassembly and install of valve springs, as previously my camera died whilst filming install on my own car.
Thank you for watching and your support!
