The short answer
Lowering springs are the cheaper, simpler way to drop a car a modest amount and keep factory dampers, but they cannot be adjusted and can overwork the dampers. Coilovers cost more and let you set height, and often damping, for summer and winter, at the price of more exposed threads for salt to attack. On Winnipeg roads, quality matters more than type: cheap coilovers fail here fast.
What each one is
Lowering springs replace the factory coil springs with shorter, usually stiffer ones, keeping the original shocks or struts. Coilovers replace the spring and damper together as one adjustable unit with a threaded body, so ride height can be set, and on better units the damping can be adjusted too. Both lower the car; they do it with different compromises.
Ride quality on rough roads
This is where Winnipeg decides. A lowered car has less suspension travel, so a pothole that a stock car absorbs can bottom a lowered one. Lowering springs on factory dampers often ride worse than people expect, because the damper is now working outside its designed range and wears quickly. Well-matched coilovers with correct spring rates and damping can ride better than springs alone while being lower, but cheap coilovers with crude damping ride worst of all. Spend on quality, not on how low it can go.
Adjustability for a two-season city
Coilovers let you run a sensible winter height and drop the car for summer, with an alignment at each change. Springs are a fixed drop; what you have in July is what you have in January, snowbanks included. If the car is a year-round daily driver, that flexibility is the strongest argument for coilovers.
Salt, corrosion and longevity
Threaded coilover bodies and adjusters corrode in salt. Without cleaning, greasing and covers, a winter or two can seize them so they are no longer adjustable. Springs have little to seize. If the car will see winter and you choose coilovers, choose a brand with good corrosion protection and budget for maintenance.
What else changes when you lower a car
- Alignment: camber and toe move with ride height. Many cars need camber adjustment kits to get back into a usable spec.
- Geometry: too low and the control arms angle upward, hurting handling. Roll centre correction may be needed for big drops.
- Clearance: tires, fenders, sway bars and the oil pan all get closer to things.
- Driveline: CV joints and axles on lowered front-drive and all-wheel-drive cars run at steeper angles.
