If you've just picked upward an old Mazda and you're searching for rx7 fc coilovers , you probably noticed pretty quickly that the stock suspension system from the late 80s feels more like a Cadillac than a sports car simply by today's standards. Nearly all FCs out presently there are running upon original shocks that have long since given up the ghost, leaving you with a ride that's bouncy, vague, and sits far too high. Swapping out those old struts for a contemporary set of coilovers is arguably the one best thing you may do to transform how the vehicle feels, whether you're thinking about hitting the local drift outlet or just want a clean street car that doesn't scrape its door handles on the sidewalk every time you consider a corner.
The FC framework is a bit of the weird beast. It had been ahead associated with its time with things like the DTSS (Dynamic Monitoring Suspension System) in the rear, which actually allowed for a bit of passive rear-wheel steering. Whilst that was awesome in 1986, it's usually the 1st thing people try to tune out there when they shift to a significant coilover setup. When you start buying around, you'll get a massive range of prices, but the old saying "you get what you pay for" really hits home here.
Why You Really need Coilovers
Let's be honest, fifty percent the reason all of us buy rx7 fc coilovers is to get rid of that will massive wheel difference. The factory height on an FC makes it appear like it's prepared for a move stage. But beyond the aesthetics, the particular performance jump is massive. A good set of coilovers provides you independent height adjustment, meaning you can drop the vehicle without messing with the spring preload. This is huge because this allows you to keep the particular full stroke of the shock even if the car is definitely slammed.
After that there's the adjustability. Most contemporary kits come with 24 to 32 "clicks" associated with dampening adjustment. When you're driving in order to the track, you retain it soft so that your spine doesn't shatter on the freeway. Once you make it happen, you stiffen it up to keep the particular body flat via the turns. It's that versatility that makes coilovers a better choice than just throwing some decreasing springs on older, tired struts.
Understanding Spring Prices for the FC
One of the most complicated parts of buying rx7 fc coilovers is figuring out what springtime rates you actually require. You'll see figures like 8k/6k or 10k/8k thrown around on the community forums. Basically, the higher the quantity, the stiffer the spring.
For the street-driven FC, an 8k front and 6k rear setup is usually the particular "sweet spot. " It's firm enough to feel nice but won't allow you to regret your living choices every time you hit a pothole. If you're building a devoted drift car or even a track monster, you might want to bump that up to 10k/8k or even higher. Just remember that the FC is a relatively light car. In case you go too stiff, the vehicle will certainly actually become skittish because the suspension system won't be capable to "work" plus soak up the bumps, which in fact reduces your grip.
The Front side Camber Plate Circumstance
Most good rx7 fc coilovers come with integrated camber discs on the front side assemblies. This is a lifesaver with regard to the FC because the factory adjustment is pretty limited. When a person lower the vehicle, your geometry adjustments, and having the ability to dial in some negative camber from the top hat makes a world of difference for turn in response.
The rear is really a different story. The particular FC uses the semi-trailing arm set up within the back, which usually means you can't just slap a camber plate on top. To really repair the trunk geometry when you're low, you'll eventually need to look into personal camber sub-links or perhaps a center link, but for a basic setup, the coilovers on their own will handle the bulk of the task.
Dealing along with the DTSS
I mentioned the DTSS earlier, and it's something you have to consider when installing your brand-new setup. The factory rear bushings permit some toe-in plus toe-out movement below load. When a person install stiff rx7 fc coilovers , that movement can start to feel capricious and "wiggly" mid-corner. A lot associated with guys choose in order to install DTSS eliminator bushings at the same time since their coilovers. Much more the rear end a lot more predictable, which is what you desire when you're trying to push the vehicle.
Budget versus. Mid-Range vs. High-End
It's luring to go for the cheapest set of rx7 fc coilovers you find on eBay for $300. Don't do it. Those budget kits usually have awful valving and spring suspensions that sag after 6 months. You'll end up spending more money replacing these questions year than in the event that you'd just bought a decent set in order to begin with.
The mid-range is where most FC owners live. Brands such as BC Racing, Fortune Auto, or Position offer great kits that are rebuildable and come with solid warranties. Fortune Auto, in particular, is a preferred because they hand-assemble their kits and actually dyno-test the shocks. If you've got a larger spending budget, you can look into something like Ohlins or KW, but for 90% of the people building an FC, the particular mid-range stuff is more than enough to get the job done.
Installation Tips and Tricks
Installing rx7 fc coilovers isn't a headache, but it's not a 20-minute job either. The front is usually straightforward—just three mounting bolts on the top and 2 big bolts upon the knuckle. The rear is exactly where things get a bit tight. You'll need to draw the interior materials in the hatch region to get at the best nuts, which may be a pain if your own interior is brittle and old (which, let's face this, most FC interiors are).
A pro tip: make use of plenty of PB Blaster or some sort of penetrating oil upon those lower swagger bolts a few days before you begin. These cars are 30+ years old, and the ones bolts have most likely been through thousands of heat process and maybe some road salt. The last thing you want is to snap the bolt within the knuckle and turn a Saturday afternoon job into a week-long headache.
The particular Importance of an Alignment
I actually can't stress this enough: get an alignment immediately right after installing your rx7 fc coilovers . Also if you believe you've got the particular ride height completely even, your toe and camber configurations will be all over the place. Driving an unaligned car won't just kill your tires; it can make the particular car feel twitchy and dangerous. Give the springs a couple days to settle, after that bring it to a shop that understands how to deal with lowered cars. Inform them what you're using the vehicle for, and these people can help you dial in the settings to match your driving a car style.
Final Thoughts
With the end associated with the day, choosing out rx7 fc coilovers comes down to how you intend to make use of the car. When it's a weekend break cruiser, don't over-spring it and make it miserable in order to drive. If it's a dedicated track toy, spend the additional money on a kit with high-quality valving that may handle the abuse.
The FC chassis is one of the most rewarding cars in order to drive when it's set up correctly. They have that perfect 50/50 weight submission and a short wheelbase that can make it feel extremely flickable. When you obtain it off individuals old, mushy manufacturing plant shocks and onto a modern set of coilovers, you'll finally understand why these types of cars have such a cult adhering to. It's an investment that pays off every time you hit a twisty backroad or pull into a car meet with that perfect, aggressive stance. Simply take your time, seek information, and don't cheap out upon the parts that literally hold your own car to the particular road.
