How Low Is Legal? Lowering Rules in Virginia and Other States
There is no single national rule for how low your car can sit. Lowering laws in the US are set state by state, and they measure different things. Virginia sets a bumper height range, while California bans any part except the wheels from hanging below the wheel rim.
That is the honest answer, and it is why we never tell a customer a certain drop is legal. A ride height that passes in one state can draw a ticket in the next. What we can do is show you how two real statutes read and what they measure. Then we cover how to check your own state before you set your coilover kit low.
Not legal advice
This is general information, not legal advice. Statutes change. The summaries below were checked against the official sources as of October 2026. Confirm the current rules for your state before you lower your car.
Why Lowering Laws Vary by State
Each state writes its own equipment rules. Some set a number, like a bumper or frame height. Others set a condition, like no part of the car below the wheel rim. Some also run safety inspections that check tire clearance, suspension parts and lights.
So the same car can be fine in one state and out of spec in another. Your state's rules, not the kit, decide what is allowed. A height-adjustable kit helps you get there, because you can set ride height to a measured number. But the kit does not make any drop legal on its own.
Here are two statutes that show the two main ways lowering laws are written.
Virginia Code 46.2-1063: Bumper Height and Ground Contact
Virginia's rule is Code of Virginia 46.2-1063. For passenger cars, it is built around bumper height. It covers a passenger car that has been modified to change its height. Such a car is barred from public highways if its bumpers are "not within the range of fourteen inches to twenty-two inches above the ground."
Bumper range. Passenger car bumpers must sit between 14 and 22 inches above the ground. The statute measures to the lower edge of the main bumper bar, not bumper guards.
Lowered or missing bumpers. If the bumpers were lowered or the car has none, the statute says height is measured "to the bottom of the frame rail."
No contact. A car may not be modified so its body or chassis contacts the ground, or its wheels contact the body in normal operation. The fuel tank may not be left exposed to collision damage.
Front to rear. A passenger car may not be modified so the front bumper sits four or more inches higher than the rear.
Suspension parts. Original suspension parts may not be disconnected in a way that defeats safe operation. The statute allows heavy-duty shock absorbers and overload springs.
The statute was amended in 2026 (chapter 497). That change lets a court dismiss a summons when the driver shows proof of compliance on or before the court date. The statute also exempts cars built or modified for races off public highways.
California CVC 24008: The Wheel Rim Rule
California takes a different approach. California CVC 24008 does not set a bumper number. It bars a modified passenger car from the road if any part but the wheels sits below the lowest part of the rims.
Picture a line across the bottom of your wheel rims. Under 24008, nothing but the wheels may hang below it. That includes the front lip, exhaust, oil pan and subframe. Wheel and tire size change where that line sits, so measure with the wheels and tires you actually run.
Notice what the rule does not say. It does not give a safe drop in inches. A car can meet 24008 and still scrape on a steep driveway, which is a different problem.
How to Check the Lowering Laws in Your State
Do not count on finding a simple lowering chart. Here is how to find the real answer.
Read the statute
Search your state's code for equipment or modification rules. Look for bumper height, frame height, ground clearance and wheel or rim language.
Check the inspection rules
If your state runs safety inspections, read the inspection manual too. Inspections often check tire contact, suspension condition and lights.
Watch the lights
A lower car puts the headlamps lower. If the drop is uneven front to rear, the aim changes as well. Have the aim checked after you lower the car.
Ask locally
When the wording is unclear, ask your state's DMV or a licensed inspection station. Forum posts are not the law.
Coilovers, Ride Height and Staying Inside the Rules
A coilover kit gives you something lowering springs cannot: a ride height you choose and can change. That matters when the rule is a number. If you move to a state with a different rule, you can raise the car instead of buying new parts. Our guide to coilovers vs lowering springs covers the other trade-offs.
On full-length kits like BC Racing and Fortune Auto, height is set at the lower mount. The spring perch sets preload. That means you can raise or lower the car without changing preload. Once it is set, tighten each locking collar so it stays put. Our guide on how to set ride height on coilovers walks through measuring all four corners.
Measure the way the law measures. For a bumper rule, measure to the lower edge of the bumper bar on level ground. For a rim rule, check the lowest parts of the car against the bottom of the rim. Write the numbers down.
Keep a simple record. Note the date, the four corner heights and the wheel and tire sizes, and take a photo with a tape measure in frame. If you are ever stopped, a measured, documented height is easier to explain than a guess. In Virginia, proof of compliance can matter in court under the 2026 amendment.
Then check clearance through full travel. A tire that rubs the body over bumps can break a no-contact rule even when the static height is fine. Get an alignment after any height change, because camber and toe move with ride height.
Picking a Kit With the Rules in Mind
Every brand in this section builds coilovers with adjustable ride height. That is the feature that helps you stay inside your state's lowering laws. The brand choice comes down to how you drive.
Bilstein invented the monotube damper. Take the Bilstein B14 PSS listed for the 2017 to 2021 Civic, including Sport and Sport Touring. It has fixed damping and adjustable height, a simple setup for a street car.
BC Racing uses nitrogen-charged monotube dampers. The BR Series has 30-click simultaneous compression and rebound. Swift Springs SPEC-R springs are an upgrade option on most BC Racing fitments.
KW brings German engineering and TÜV certification on most kits. KW also builds HLS (Hydraulic Lift System) on selected KW V3 and higher kits, which lifts the front axle for driveways.
Fortune Auto hand-builds in Virginia. It lists the G37 in both rear styles, including this Fortune Auto G37 true style rear kit. TEIN and Öhlins round out the lineup.
Remember that a coilover kit does not automatically cut unsprung weight. The wheel, tire, brakes and hub make up most of it. Heavier wheels add unsprung weight, so weigh that when you pick wheels for the rim rule. Want more on how performance suspension changes your car? Start with what are coilovers.

Frequently Asked Questions
How low can a car legally be in the US?
There is no single national number. Each state sets its own lowering laws. Virginia uses a 14 to 22 inch bumper range for passenger cars. California bans any part except the wheels from sitting below the lowest part of the rim. Check your own state.
Are coilovers legal?
Coilovers are a common aftermarket part, but legality depends on how you set the car up and on your state's rules. What usually matters is the result: bumper or frame height, ground clearance, tire contact and lights. Set your height to meet your state's rule.
How is bumper height measured in Virginia?
Virginia measures to the lower edge of the main horizontal bumper bar, excluding bumper guards. If the bumpers were lowered or removed, it measures to the bottom of the frame rail. Measure on level ground.
What does California CVC 24008 say about lowered cars?
It bars driving a modified passenger car if any part other than the wheels sits below the lowest part of the rims. It does not set a drop in inches.
Can I get a ticket for a lowered car?
Yes, if the car breaks your state's rules. In Virginia, a 2026 amendment lets a court dismiss a summons if you show proof of compliance by the court date. That is a reason to set your height to a measured, compliant number.
Does a coilover kit make lowering legal?
No. A kit only gives you the ability to set ride height. Whether the result is legal depends on where you set it and on your state's rules. That is why height adjustment matters.
Will lowering affect my headlights?
It lowers them, and an uneven drop changes the aim. If your state inspects cars, the inspection may check your lights. Have the aim checked after you set your final ride height.
Questions About Your Ride Height?
We will not tell you a drop is legal, because your state decides that. We will help you pick a kit that lets you set the height your state allows.
