Without even reading that or this thread, cut springs =
dangerous epic fail.
Springs are held in place because they are under contant tension due to their length, which is matched for the suspension setup of a given car. Lowering springs are often the same length but have progressive coils (They get tighter towards the centre) meaning that when the car is dropped to the floor, the outer few coils compress and often touch, with the inner, closer coils doing the job normal springs do. This is why lowering springs are always harder.
Cutting springs means that they are too short. This has two significant implications...
- Should the car ride up on a bump and the lower arms drop so far, the spring will unload and because it is too short, it will fall out of it's mounts. This will cause at best, fouling of the wheel, which will lock up.
- A shorter spring will lower the car. Said car will be closer to the ground and will also have less suspension travel. Due to the fact the spring rate has not been increased (Using aforementioned progressive lowering springs) means that the springs will fully compress and/or the shock will bottom out, producing some incredibly iratic handling characteristics, especially on bumpy ground.
Either of the 2 points above could cost you, a passenger, or an innocent person, their life. Is it
really worth it for the saving cost of a set of lowering springs (£120 if you look)?
