If you're relying on bump stops then the springs are too short......
I don't think the bottom coil is flat enough to seat on the shock, that's why they move about.
Standard mounts mask them moving as its a massive soft rubber, solid doesn't hide the design flaw
Let me clear up a few of peoples questions. The bump stop should ALWAYS be installed in the shock, they are designed to prevent the shock from bottoming out on itself (and breaking).
All our spring does from a shock point of view is allow it to operate in a different section of its range (the same as ANY other lowering spring). Springs that are "too low" for the standard length shock will only cause it to run on the bump stop. Ours are NOT within that category.
You can move the spring by hand under full droop which is NOT an issue what so ever!! How often is it at full droop anyway?
There is not a design flaw with these at all Danny, the solid top mount transfers more of the suspension feedback into the steering (hence why people fit them). If you fit them with a stiffer spring, you will get more feedback into the car, simples. I would appreciate it if you didn't make false accusations like that Danny, doesn't look good for 519 Automotive.
If anyone has any questions, please feel free to give me a ring/email. I am happy to answer anything with regards to our springs
