Any part that serves any dynamic function that needs to be rated and needs to be consistent that comes from the chinaspeed factory is at risk of being a complete lie.
Back when I was having "fun" messing around with OEM type springs since that's what I was limited to at the time in the racing I was competing in, I procured and measured several different OE type springs. The worst offender of them all was this Megan Racing front S-chassis lowering spring. This is advertised as ~350 lbs/in which no other company even comes close to. The second I opened the package I knew immediately it was a lie just by looking at the spring wire diameter. You can calculate the spring rate yourself: Free length: Compressed to a little more than what the static corner weight on the front of an S-chassis is: And then a little more the spring is completely blocked and the force spikes: |
