Quick Answer
Match the part to the problem before you buy. If the car feels loose or clunks over bumps, start with control arms. If it leans too much in corners, add model 3 sway bars. If you want adjustable ride height and comfort, choose a coilover kit like the MSS Sports Performance / Comfort Fully Adjustable Coilover Kit. If you only want a wider stance on stock wheels, a flush spacer kit is the cheapest change.
A Tesla Model 3 suspension upgrade is not one purchase — it is a chain of decisions. Control arms and bushings fix worn or vague front-end behavior. Sway bars tune body roll. Coilovers change ride height, damping, and comfort together. Spacers change stance without touching geometry. Buy the wrong part first and you will spend twice.
This guide gives you decision rules for each category, plus honest fit limits. Every specification below comes from the product listing, so if a number is not listed, treat that as unknown and confirm before ordering.
Start With the Symptom, Not the Part
Before ordering anything, describe what the car actually does. A clunk or shimmy over broken pavement points to control arms, bushings, or sway bar end links. A floaty, leaning feel in corners points to sway bars or dampers. A harsh ride over small bumps points to coilovers or tired bushings. A stance that looks narrow with stock wheels points to spacers.
Write down the symptom, the speed or road where it appears, and whether it changed after a tire or wheel swap. That note decides which category you shop first and prevents buying a coilover kit to fix a worn control arm.
- Clunk or rattle over bumps: inspect control arms, bushings, and end links first.
- Excess body roll in corners: sway bars and damping are the levers.
- Ride too stiff or too soft: coilovers, not spacers, are the fix.
Control Arms and Bushings: Fix Wear Before You Tune
Control arms locate the wheel and hold alignment. When bushings degrade, you get vague steering, uneven tire wear, and noises that no sway bar will cure. Replace worn arms before adding performance parts, because a new sway bar on a worn arm just transfers load into a tired joint.
Choose OE-style arms for a stock daily driver, and adjustable or reinforced arms only if you are lowering the car and need to correct camber. If a listing does not state a camber range or a bushing material, do not assume it — ask before buying.
- Replace in pairs and get an alignment immediately after.
- If you lower the car, budget for adjustable arms to bring camber back into spec.
Sway Bars: The Cheapest Handling Change
Model 3 sway bars reduce body roll by tying the left and right sides of the suspension together. A stiffer rear bar reduces understeer and makes the car rotate more willingly. A stiffer front bar increases understeer but sharpens initial turn-in. Most daily drivers are happiest with a mild rear-biased upgrade.
Sway bars do not lower the car, do not fix worn bushings, and do not change ride height. They also make the ride firmer over one-wheel bumps, because the bar links the two sides. If your commute is rough pavement, keep the stiffness increase modest.
- Buy bars with new end links and bushings — reusing worn links causes noise.
- Adjustable bars let you tune stiffness after installation; non-adjustable bars do not.
Coilovers: Ride Height, Comfort, and Cost Together
A coilover kit replaces springs and dampers as one adjustable unit. That lets you set ride height and, on better kits, tune comfort versus control. It is the biggest single change you can make, and also the one with the longest lead time and highest install cost.
The MSS Sports Performance / Comfort Fully Adjustable Coilover Kit for Tesla Model 3 gives a front adjustment range of 0 to -40mm (+/-3mm) and a rear range of 0 to -35mm (+/-3mm), and includes springs, ride adjusters, and adjuster tools. It fits the Model 3 sedan and ships within 4-8 weeks, so plan the install around that window.

- Decide your target drop before ordering; extreme drops need alignment and possibly adjustable arms.
- Confirm the shipping window before booking an install appointment.
Spacers and Stance: Cheap, Visible, and Fit-Sensitive
Wheel spacers push the wheels outward to fill the fender. They do not change spring rate, damping, or ride height, so they are a stance purchase, not a handling fix. They also change scrub radius and can cause rubbing if you run wide tires or an aggressive drop.
The EVANNEX Wheel Spacer Flush Kit for Tesla Model 3 pushes the wheels out 15mm front and 20mm rear and is sold as a set of four spacers with 20 extended titanium wheel studs. It fits all Standard, Mid, and Long Range Model 3 but is not for Performance Model 3 — check your trim before ordering.

- Verify your trim: the EVANNEX flush kit excludes Performance Model 3.
- Recheck lug torque after the first 50-100 miles of driving.
Decision Rules: What to Buy First
- You hear clunks or the steering feels vague: Inspect control arms, bushings, and end links before buying any performance part. Replace worn arms in pairs and align the car. Fix wear first; tuning a worn suspension wastes money.
- You want less body roll but a stock ride height: Choose model 3 sway bars with new end links and bushings. Keep the stiffness increase mild on rough roads. Sway bars are the lowest-cost handling change.
- You want adjustable height and comfort in one purchase: Choose the MSS Sports Performance / Comfort Fully Adjustable Coilover Kit, confirm the 0 to -40mm front and 0 to -35mm rear range meets your target, and plan around the 4-8 week ship time. Coilovers are the biggest change and the longest lead time.
- You only want a wider stance on stock wheels: Choose the EVANNEX Wheel Spacer Flush Kit if you drive a Standard, Mid, or Long Range Model 3. Performance Model 3 owners need a different solution. Spacers change looks, not handling.
Product Facts That Affect Your Decision
- EVANNEX Wheel Spacer Flush Kit for Tesla Model 3: Pushes wheels out 15mm front and 20mm rear; suitable for all Standard, Mid, and Long Range Model 3 (not for Performance Model 3); sold as a set of four wheel spacers and 20 extended titanium wheel studs. Gives a flush stance on stock wheels, but Performance owners must choose a different kit.
- MSS Sports Performance / Comfort Fully Adjustable Coilover Kit for Tesla Model 3: Front adjustment range 0 to -40mm (+/-3mm) and rear 0 to -35mm (+/-3mm); includes springs, ride adjusters, and adjuster tools; fits Tesla Model 3 sedan; ships within 4-8 weeks. Lets you set ride height and comfort in one purchase, but the 4-8 week lead time must fit your schedule.
- DBA T-Slot T3 4000 Series Rear Rotor Set For Tesla Model S: Fits 2012+ Tesla Model S Rear; features improved fatigue resistance to minimize surface cracking, Kangaroo Paw ventilation, and reduced rotor fatigue during prolonged heavy braking. A Model S part, not a Model 3 part — useful only if you also own a Model S and want matching brake upgrades.
Fit Guidance: Check Before You Order
Best for
- Daily-driven Standard, Mid, or Long Range Model 3 owners who want a flush stance with the EVANNEX Wheel Spacer Flush Kit
- Model 3 sedan owners who want adjustable ride height and comfort from the MSS coilover kit
- Owners chasing body roll who will pair sway bars with fresh end links and bushings
Not for
- Performance Model 3 owners shopping the EVANNEX flush spacer kit, which excludes that trim
- Model Y or Model S owners, since the coilover and spacer kits listed here are Model 3 specific
- Drivers who need the car back on the road this week, because the MSS coilover kit ships within 4-8 weeks
Buy the part that matches your symptom, confirm trim fit before checkout, and budget for an alignment after any geometry change. Control arms and bushings restore what wear took away, sway bars tune balance, coilovers set height and comfort, and spacers change stance only. Get the order right and each purchase builds on the last instead of undoing it.
