Lowering Spring Measurements

[Mertyvw]

Hi guys , after driving a couple of cars with coilovers i decided to stay with the Springs the ride is too hard on coilovers.

So the question is how is the measurements for the lowering springs work

I want to buy them but is says like 60mm drop 40mm drop how can i know which one i want.

What i want is the car to sit just above the tyres not too low on the ground.
And would only changing the springs be ok ?

You want 40mm drop, anymore will be rubbing.

H&Rs are good. I should have some coming off within the next month or 2. Have a look at my build thread and it will give you a rough idea how low they go!
