Coilovers
A complete shock-and-spring assembly with a threaded body that lets you dial in ride height, and on better kits, damping stiffness too. You are replacing the entire damper, not just the spring.
Best for: Enthusiasts who want adjustable ride height, sharper handling, or a track/show setup and will keep the car a while
Typically $500–$1,500 per set for street kits; $2,000–$4,000+ for premium adjustable kits, plus $300–$600 install and alignment
- Ride height is adjustable — set your exact stance without guessing at a fixed drop
- Matched spring and damper, so the ride quality and handling are engineered together
- Mid and upper kits add damping adjustment to tune firmness for street, canyon or track
- Corner-balancing is possible, letting you optimize weight distribution on a performance car
- Renews the whole damper, so you are not bolting new springs onto tired old shocks
- Two to four times the cost of springs once you add install and alignment
- Budget kits can ride harshly or wear out fast — the cheap ones are a real trap
- Threaded collars can seize with road grime if never adjusted or greased
- More complexity and more ways to set it up wrong (too low, too stiff, wrong preload)
Lowering Springs
Shorter, stiffer coil springs that drop the car a fixed amount while reusing your existing shocks or struts. The cheapest, simplest way to lose the factory wheel gap.
Best for: Owners on a budget who want a modest, good-looking drop and mostly street driving
Typically $200–$400 per set, plus $200–$500 install and alignment
- Far cheaper up front — often a third of the cost of a decent coilover kit
- Simple concept: a fixed, known drop (usually 1–2 inches) with predictable results
- Lowers center of gravity and cuts body roll for a modest handling improvement
- Reuses your shocks, so no need to replace the whole damper if it is healthy
- Drop is fixed — no adjustment if you want it higher for a driveway or lower for a show
- Stiffer springs on stock-valved shocks can ride poorly and wear the shocks faster
- Best results really need matching shocks, which erases much of the price advantage
- No damping adjustment — you are stuck with whatever the spring-and-shock pairing gives

What actually separates coilovers from lowering springs
Both parts do the same headline job — they lower your car and firm up the suspension — which is exactly why owners cross-shop them. But they are very different amounts of hardware, and understanding that difference is the whole decision.
Lowering springs are just that: shorter, stiffer replacement coil springs. You unbolt the factory springs and fit these in their place, reusing your existing shocks or struts. The spring is shorter, so the car sits lower by a fixed amount the manufacturer designed in — typically a 1 to 2 inch drop. The spring rate is higher, so the body rolls less in corners. That is the entire mechanism. It is a spring swap, nothing more.
Coilovers replace the whole damper. A coilover is a complete assembly — a new shock absorber with a coil spring wound around a threaded body. The threads let you spin a collar up or down to set ride height anywhere in the kit's range, rather than accepting one fixed drop. Better kits add adjustable damping, so you can turn the shock's firmness up or down with a knob. Because the spring and damper are engineered as a matched pair, the ride and handling are tuned together instead of hoping a stiff spring gets along with a stock-valved shock.
The cleanest way to hold the two in your head: lowering springs change one component and accept the rest of your suspension as-is; coilovers replace the corner and hand you the adjustment knobs. That extra capability is why coilovers cost multiples more — you are buying dampers, springs, height adjustment and often damping adjustment all at once, versus buying springs alone.
Adjustable vs fixed: the ride-height question
This is the single biggest practical difference, and for a lot of buyers it settles the whole argument. Lowering springs give you a fixed drop. Whatever the box says — say 1.4 inches front, 1.2 rear — is what you get, forever, until you change springs again. There is no fine-tuning it later.
Coilovers let you set the height by spinning the collars, anywhere within the kit's travel. That flexibility matters more than people expect:
- Fitment. You can nudge the car up an eighth of an inch to clear a steep driveway or parking ramp, or drop it for a car show, without replacing anything.
- Corner-to-corner leveling. Cars are rarely perfectly even from the factory. Adjustable height lets you dial each corner to sit level, or corner-balance a performance car so weight is distributed the way you want.
- Wheel and tire changes. New wheel offset or tire size can change how the car looks and clears; coilovers let you adapt the stance to match.
With springs, you are committing to the engineer's single answer. With coilovers, you own the dial. If you already know the exact modest drop you want and will never touch it again, the fixed spring is fine. If you enjoy tuning, run different wheel setups, or fight a low driveway daily, the adjustability alone can justify the price step.
Ride quality and handling: what each really delivers
Here is where the honest picture gets nuanced, because the answer depends heavily on how well each setup is matched. A common assumption is that stiffer always means better handling and worse comfort. Reality is more specific.
Lowering springs deliver a modest handling gain — a lower center of gravity and less body roll — but they are limited by the shocks you keep. A stiffer spring asks the shock to control more energy on a shorter stroke. If that shock is stock-valved and healthy, the result is acceptable but rarely great; if it is worn, the car can ride harshly, bounce, and chew through the shock faster. The consensus among enthusiasts is that springs are only as good as the shocks they land on.
Coilovers can ride better and handle better than lowering springs — but only if the kit is decent. A quality street coilover matches spring rate to damper valving, and the adjustable damping lets you soften it for daily driving or firm it up for a canyon run. Owner reviews consistently praise good mid-tier kits for a ride that is controlled without being punishing. The flip side is the cheap-kit trap: bargain coilovers often pair crude, non-rebuildable dampers with harsh springs, and owners frequently report a jarring ride and short lifespan. A cheap coilover can genuinely ride worse than well-matched springs. Spend enough to clear the bottom tier, and the coilover wins on both ride and handling; buy the cheapest kit on the shelf and you may have paid more for less.
The lowering-spring trap: your old shocks
This is the mistake that quietly ruins the most lowering-spring installs, and it is worth its own section. Because springs reuse your existing shocks, the temptation is to bolt them onto whatever is already on the car and save money. On a car with 80,000-plus miles and original dampers, that is a false economy.
Stock shocks are valved for the stock spring rate. Put a stiffer, shorter lowering spring on a tired shock and two things happen: the ride degrades because the worn damper can't control the firmer spring, and the shock wears out even faster because it is now working harder over less travel. Owners who skip this step commonly report a bouncy, crashy ride and a blown shock within a year or two — then end up buying shocks anyway.
The mechanic and enthusiast consensus is that lowering springs should be paired with fresh shocks designed or rated for a lowered application. Once you add that cost — a set of quality matched shocks plus the springs plus install — the price advantage over an entry-level coilover narrows sharply. That is the crux of the value comparison: springs are cheap only if your shocks are genuinely healthy, and honest about it.
Real cost and value over the life of the car
On the sticker, springs win easily — a good set runs $200–$400 against $500–$1,500 for a solid street coilover kit, and premium adjustable kits climb to $2,000–$4,000+. But the honest number is the fully-installed, correctly-done cost, and that changes the math.
A proper lowering-spring job is springs plus install plus an alignment, and, if the shocks are aging, a matched set of shocks too. Add those matched shocks and you are often at $600–$1,000 installed — brushing up against the price of a capable entry-to-mid coilover kit that arrives as one matched, height-adjustable package with new dampers included. At that point the coilover is arguably the better value because you are not layering new springs onto reused parts.
Where springs stay clearly cheaper is the case where your existing shocks are genuinely good — a newer car, or one you recently re-shocked — and you want a simple, permanent modest drop. Then springs do exactly one job cheaply and there is no reason to overspend. Over the life of the car, coilovers also hold an edge if you keep the vehicle: mid and premium kits are often rebuildable, so a worn coilover can be serviced rather than scrapped, while a blown budget shock under lowering springs is a throwaway. Match the spend to how long you'll own the car and how hard you'll drive it.
Common myths and mistakes
"Coilovers always ride worse than springs." Backwards for a good kit. A quality, properly-valved coilover usually rides better than lowering springs because the damper is matched to the spring. The harsh-ride reputation comes from cheap kits and from people running them slammed with too much spring preload.
"Lowering springs are a bolt-on with no downside." Only if your shocks are healthy and rated for the drop. On worn or mismatched shocks they ride badly and shorten shock life. Springs are a partial upgrade, not a complete one.
"Lower is always better." No. Excessive drop — from either setup — causes bump-steer, reduced suspension travel, premature tire and CV wear, and a car that bottoms out on real roads. A modest, well-aligned drop handles and lasts better than a slammed one.
"Any coilover is an upgrade over springs." Not the cheapest ones. Bargain-bin coilovers can ride worse and die sooner than well-matched springs. If your budget only covers a no-name coilover, quality springs plus good shocks are often the smarter buy.
"I don't need an alignment." You do. Any ride-height change alters camber and toe. Both setups require a four-wheel alignment afterward, and skipping it wears tires quickly and can ruin handling.
Which should you buy — and how to decide
This one genuinely depends on budget and intent, so match the part to your goal rather than chasing a single winner.
Buy lowering springs if you want the cheapest clean drop, you mostly drive on the street, your shocks are healthy (or you'll budget matching shocks with them), and you're happy with one fixed height you won't change. This is the smart-money path for a modest, good-looking stance on a daily driver.
Buy coilovers if you want to set your own ride height, you care about sharper or tunable handling, you're building for track, autocross or shows, or you'll keep the car long enough to value adjustability and rebuildable dampers. Budget for a mid-tier kit or better — the cheapest coilovers undercut the whole reason to buy them.
Whichever you choose, get a four-wheel alignment afterward, avoid slamming the car below a sane drop, and prioritize a matched setup over a cheap one. The worst outcome in this comparison isn't picking the "wrong" side — it's pairing stiff springs with dead shocks, or buying a bargain coilover that rides like a brick. Spend where it counts and both paths deliver a lower, better-driving car.
