bluechipbmw Posted February 17, 2006 Share Posted February 17, 2006 Swift: Front: 20-25mm drop Rear: 10-15mm drop Front: K=42.5N/mm Rear: K=66N/mm $500 Ion: Front: 30mm drop Rear: 25mm drop Front (progressive): K=40N/mm (first inch of compression) K=52N/mm (by second inch of compression) Rear: K=67N/mm About $400 Hey Hans - What contributes to the measure of the drop? Is it the actual measure in height of the spring? If there were 2 different springs side by side and both measured the same height can they have a different drop?

Scooter Posted February 18, 2006 Share Posted February 18, 2006 ^^^ A LOT. You can't compare springs by their unloaded dimensions. Seek first to understand, then to be understood. In other words: SEARCH before you post! Link to comment Share on other sites More sharing options...

Swifts can be had for MUCH cheaper than $500 now. Just check the vendor for-sale forum! Link to comment Share on other sites More sharing options...

PhoenixMrx2 Posted February 22, 2006 Share Posted February 22, 2006 OK... From the pictures Ive seen it looks like the swifts drop the car more... but according to Han'sGT's info the ions are actually more of a drop. Which actually lowers the car more?

iON Performance Posted February 22, 2006 Share Posted February 22, 2006 PhoenixMrx2 - The amount of lowering that our Sport Spec springs lower the car are based on using USDM OEM struts. The Swifts could've been measured while on different struts (ie: non USDM OEM). Link to comment Share on other sites More sharing options...
