FS: Swift sport mach lowering springs
Swift sport mach lowering springs
Up for sale is a set of Swift Sport Mach lowering springs. The springs were cut slightly to lower the car a little more. It didn't affect them since they are rated and not progressive rate springs. Springs were great on the car and had an aggressive feel. People always thought the car was on coilovers. I'm asking $130 plus $20 shipping. Paid over $350 for these new. They were on the car about 10,000 miles. Pm with any questions. I will accept PayPal only. The one pic shows how my car set on these springs.

Can you please post a picture of one of the front springs that you cut?
Based on the picture you posted of a rear spring I can calculate that you cut off about 3/4 of one loop. Takes the spring rate from 364lbs to about 427lbs. Not a deal breaker, 05+ cars have a 427lbs rear rate from the factory.
BUT, I need to see a picture of a cut front spring so I can run the same numbers.
Progressive springs don't have to have groupings of tightly spaced coils. It can also happen courtesy of changes in coil diameter. But your right, they are linear springs.

Found a picture of a set of uncut Swift 350Z springs, that lets me count how many active coils the front and rear springs have. Knowing that, I can tell how much spring has been cut off.
Since Swift publishes what their spring rates are out of the factory, I can calculate what the spring rate would be based on how much spring was cut off. It's accurate give or take a few pounds.
When you remove the amount of active coils from a spring, spring rate goes up.
