The Datsun 510 earned its reputation because it feels light, eager, and honest. Even now, it’s still one of the most rewarding old chassis you can drive hard. But the more grip, speed, and power you ask from a classic 510, the more obvious the original suspension compromises become. Stock geometry, aging components, and limited adjustability can make the car feel less precise than the rest of the build deserves.
That’s exactly where Apex Engineered’s Datsun 510 Suspension upgrades come in. Built for the 1968–1973 Nissan 1600, 510, and Bluebird, these packages don’t just replace worn factory parts. They rethink how the chassis should work when you want sharper steering, a more stable platform, and alignment control that actually matches the way enthusiasts use these cars now. Together, the Datsun 510 Suspension Upgrades for the front and rear give the chassis a more modern foundation without losing what makes the car fun in the first place.
The front of the car sets the tone for everything else. If the steering feels vague, if the nose gets unsettled over rough pavement, or if the geometry starts working against you as the car is lowered, the whole chassis feels older than it should. That’s why Apex’s front Datsun 510 suspension upgrade kit is built as a complete system instead of a loose collection of parts.
The kit includes a front crossmember, front control arms with dust boots, quick steering knuckles, an idler arm, front tie rods, a tension arm brace, and the needed hardware. That matters because each of those pieces affects how the suspension carries load, maintains alignment, and communicates through the steering wheel. When those parts are designed to work together, the result is usually more consistent behavior instead of a patchwork of small fixes.
Apex specifically calls out improved roll center and reduced or eliminated bump-steer as core benefits. On the road, that translates into a front end that feels more settled and more faithful to your inputs. Instead of the car reacting differently as the suspension moves through its travel, you get a cleaner connection between steering input and chassis response. That’s a big deal on a 510, because the car’s light weight and compact size make small geometry improvements feel obvious from the driver’s seat.
The quick steering knuckles also fit that same goal. They support a more immediate response, so the car feels livelier and easier to place without needing exaggerated steering corrections. If you drive the car hard on a back road or take it to a track day, that sharper response helps the front of the chassis feel more intentional at turn-in instead of hesitant or delayed.
There’s also an important practical angle here. The included crossmember supports KA or SR20 engine swaps, which makes this front package more than just a handling upgrade. For builders planning a more serious street or track car, it creates a cleaner baseline that supports the next phase of the project instead of forcing a future rework.
The rear suspension is where a lot of old-car compromise tends to show up after the car is lowered and pushed harder. On the Datsun 510, the stock trailing arm arrangement can limit how precisely you tune the rear of the car, especially when you’re trying to balance grip, wheel placement, and alignment. It’s one thing for a classic chassis to feel charming. It’s another thing for the rear end to feel like it’s making decisions for you.
Apex addresses that by replacing the original trailing arm setup with a fully adjustable multilink rear geometry. That change is important because it gives you access to the kinds of alignment control that make a car easier to dial in for its actual use. Rear toe and camber adjustments can be made without unbolting components, which is exactly the kind of detail that matters when you’re chasing a setup instead of just installing parts once and calling it done.
For the driver, the biggest benefit is predictability. When rear toe and camber are easier to set correctly, the car is easier to trust. You can build a setup that feels stable on the street, more responsive in canyon driving, or more composed under repeated hard use at a track day. That doesn’t mean one magic alignment works for everything. It means the chassis stops boxing you into the old compromises that made meaningful tuning harder than it needed to be.
Apex also highlights two details 510 owners will appreciate right away. First, the adjustable mustache bar lets you fine-tune the camber curve for different driving goals. Second, the system helps eliminate the excessive camber that often shows up when the car is lowered, while also giving you the ability to center the wheel in the wheel well. Those are changes you can see in the garage, but they matter just as much behind the wheel because they help the car feel more balanced and better resolved as a whole.
There are a few practical fitment notes worth keeping in mind. The rear kit requires a coilover system and aftermarket brake kits, and slight trimming may be needed for the bracket to fit the bearing flanges. The package also accommodates exhaust systems up to 3 inches in diameter. None of that feels out of place for the kind of builder this kit is aimed at. If anything, it reinforces that this is a serious rear suspension upgrade designed for cars that are already moving beyond a mild refresh.
One of the smartest things about treating Datsun 510 suspension upgrades as a full front-and-rear system is that it changes the character of the build, not just one end of the car. A lot of classic cars end up with one noticeably upgraded section and one section that still behaves like it’s stuck decades earlier. That mismatch can leave the car feeling inconsistent no matter how good the individual parts are.
With Apex’s Datsun 510 Suspension Upgrades for the Front and Rear, the chassis gets a more complete reset. The front package focuses on steering response, roll center, and bump-steer control. The rear package focuses on multilink geometry, toe and camber adjustability, and better wheel placement. Put together, those changes give you a chassis that’s easier to align, easier to tune, and easier to build around as the car evolves.
That matters whether your goal is a sharper street car, a canyon carver, or a more committed track build. A better suspension baseline makes every other decision easier. Alignment changes become more meaningful. Tire and wheel choices become easier to support. Engine swap plans make more sense when the front structure is already ready for them. And the whole car starts to feel more cohesive, because the suspension is no longer the part of the build that’s trying to keep up.
That’s really the point of these kits. They don’t turn the 510 into something it isn’t. They let the chassis live up to what enthusiasts already love about it by removing the limitations that hold it back. You still get the compact, connected personality that made the 510 iconic. You just get it with more precision, more adjustability, and a much clearer path toward the kind of setup you actually want.
If you’re serious about improving how your 510 drives, Apex’s front and rear suspension kits make a compelling case as a matched upgrade path. The front system addresses roll center, bump-steer, steering response, and swap-friendly packaging. The rear system brings fully adjustable multilink geometry, easier toe and camber tuning, improved wheel placement, and a better answer to the usual lowered-car compromises.
For a classic chassis that still gets driven hard, that combination matters. It gives you a more confident car today and a better foundation for whatever comes next. If you’re planning Datsun 510 suspension upgrades, these kits are worth a close look.
