FL5 & DE5 Suspension Guide

Best Lowering Springs for the FL5 Civic Type R & DE5 Integra Type S: The "Mostly" Complete Guide

Real owner feedback only. No paid test groups, no sponsored influencers, none of that "we got these free so they're amazing" stuff. Every set here is compared on drop, spring rate, ride quality, and how it actually behaves on the FL5 Civic Type R and the DE5 Integra Type S. Same chassis, same adaptive dampers, so the same springs work on both. If anything is chassis specific, I'll point it out.

Why Lowering Springs?

Lowering springs tighten up body control, sharpen your turn-in, and clean up that factory wheel gap that bugs every one of us. Get the rates and travel right and you keep the daily comfort while adding real performance. Both the FL5 and DE5 respond really well to a smart spring choice. Honda already put serious engineering into the adaptive dampers, and a good spring set works with that engineering instead of fighting it.

Everything in this guide is built to run on the factory adaptive dampers and keep all three drive modes (Comfort, Sport, +R). Pick based on how you actually drive, not just how low you want to sit.

Reference: OEM Spring Rates (FL5 & DE5). Front is about 4.8 kgf/mm, rear about 4.4 kgf/mm, progressive. Use these to judge how far each aftermarket set moves away from stock feel. Once you get much past 6 kgf/mm up front, you start asking real questions of the factory dampers.

FL5 vs DE5: What Actually Differs

The Integra Type S (DE5) rides on the same platform as the Civic Type R (FL5) and uses the same adaptive damper system. That's why almost every spring in this guide is sold as a shared FL5/DE5 fitment, same part number, same spring, same behavior. The DE5 sits a hair softer and quieter from the factory and carries a touch more weight, so a set that feels firm but livable on the FL5 will feel just about identical on the DE5. The one thing to watch is that the Integra's slightly different front fascia and lower lip mean an aggressive drop shows curb clearance sooner. If a listing only names one chassis, double check it covers yours before you buy. Most of the good brands list both, but a few older SKUs still say FL5 only.

Swift Spec-R Aggressive / Track

Swift Spec-R

Front Rate
6.3 kgf/mm
Rear Rate
7.5 kgf/mm
Type
Linear
Drop F/R
-25mm / -25mm

Built for people pushing the car at HPDE, time attack, and SCCA. Made in Japan from Swift's proprietary H5S.TW material, which lets them run a smaller, lighter spring at a higher rate without coil bind. So you get less unsprung mass and quicker response. That rear-biased 6.3/7.5 split is the most aggressive setup in this whole guide, and it's not close.

Real talk: On track these are fantastic. Flat, responsive, planted. On the street a lot of owners say the ride is bouncy in all three modes, because the linear rate and stiff rear don't leave much progressive give. If your car sees more Costco runs than corners, look somewhere else. If it sees a track day a month, this is your set.

J's Racing Hyper Balanced

J's Racing Hyper Spring

Front Rate
3.5 to 5.5*
Rear Rate
2.5 to 4.5*
Type
Variable
Drop F/R
-25mm / -20mm

A chassis-exclusive design tuned right around the Type R's adaptive dampers. The variable-rate winding stays soft early in the stroke for ride comfort, then firms up as you load it. That's exactly what you want from a spring meant to work with the factory 3-mode system instead of overriding it. J's Racing builds these specifically to keep +R, Sport, and Comfort all feeling different.

Real talk: One of the smartest all-rounders here. You give up a little of the Swift's flatness, but you get a ride that's genuinely nice on rough pavement while still tightening the car up a good bit. Premium price, premium engineering.

Eibach Pro-Kit Daily

Eibach Pro-Kit

Front Rate
~5.1 kgf/mm
Rear Rate
~4.7 kgf/mm
Type
Progressive
Drop F/R
-25mm / -18mm

The default rec for a reason. Progressive rate that sits barely above stock, a modest drop that clears most driveways, and a ride that's firmer than factory but never harsh. Tested on the factory dampers, backed by Eibach's limited lifetime warranty, and there's a confirmed DE5 fitment too (-1.0" front, -0.8" rear on the Integra).

Real talk: If you want the car to look and handle noticeably better with zero drama on your daily commute, this is the safe answer, boring in the best way. Nobody regrets Pro-Kit.

Eibach Sportline Aggressive

Eibach Sportline

Front Rate
Higher*
Rear Rate
Higher*
Type
Progressive
Drop F/R
-30mm / -23mm

Pro-Kit's meaner sibling. Bigger drop at -30mm up front, higher rates to control that lower ride height, and a rear-bias rate system that keeps front-to-rear balance in check while still playing nice with Honda's adaptive dampers. This is the aggressive-stance-plus-real-handling pick from Eibach.

Real talk: The look is excellent and body control is a clear step past Pro-Kit. Just know that at -30mm you're getting close to the limit of factory damper travel, so the ride gets busier over sharp hits. Great for a street car that wants presence and a stiffer edge.

Spoon Progressive, V1 & V2 Balanced

Spoon Sports Progressive Spring

Front Rate
5.5 kgf/mm
Rear Rate
5.0 kgf/mm
Type
Progressive
Drop F/R
-20mm / -25mm (~0.8")

Classic Spoon thinking. Rate up about 10% over stock, but with some clever engineering to keep the ride livable. They extended the spring length and used an irregular-pitch, barrel-shaped coil profile that lowers the load needed to get the spring moving. So it soaks up the small stuff softly and firms up progressively for the fast stuff. That rear-heavy drop gives a subtle rake a lot of owners love.

Real talk: V2 is the current version and the one you'll actually find in stock now. It refines the V1 with the updated pitch profile above. If you want the Spoon badge and a really well-sorted balanced ride, either version delivers. Just buy V2 if you're buying new.

RS-R Ti2000 Down All-Round

RS-R Ti2000 Down Sus

Front Rate
5.61 kgf/mm
Rear Rate
5.31 kgf/mm
Type
Progressive
Drop F/R
-20/-25mm, -25/-30mm

RS-R's party trick is the Ti2000 titanium-alloy material, which resists sag over time way better than normal spring steel. So the ride height you set is the ride height you keep, years down the road. Rates land in a friendly middle ground just above stock, and the drop is on the deeper side of moderate.

Real talk: A quietly excellent all-rounder that flies under the radar. If longevity and set-and-forget height matter to you, and you never want to think about spring sag again, this is a strong, comfort-leaning pick.

H&R Sport OEM+ / Subtle

H&R Sport

Front Rate
4.5 kgf/mm
Rear Rate
5.1 kgf/mm
Type
Progressive
Drop F/R
-19mm / -15mm

The most conservative drop here, and that's kind of the whole point. Front rate actually sits a touch below stock while the rear firms up, which cleans up body motion without ever feeling stiff. Sold in a shared FL5/DE5 fitment. If your goal is looks factory-correct, just better, this nails it.

Real talk: The ride-comfort champ of the group alongside Pro-Kit. You won't win any "how low" contests, but you also won't scrape anything, and the daily comfort is great. Perfect if you want the improvement without announcing it to the whole street.

TEIN S.Tech Street / Aggressive

TEIN S.Tech

Front Rate
5.3 kgf/mm
Rear Rate
4.8 kgf/mm
Type
Progressive
Drop F/R
-20mm / -25mm

TEIN's aggressive street spring. Chrome-vanadium SAE9254V steel, green powder coat, progressive rate, and a 1-year warranty that covers sag past 5mm, breakage, deformity, and noise. Rates land firmly above stock for a noticeably sportier feel while staying tuned for the factory dampers.

Heads up on TEIN High.Tech: people ask about it all the time, but TEIN doesn't make a High.Tech spring for the FL5/DE5 chassis. The S.Tech above is the only TEIN set actually built for this platform. If you see a listing claiming "High.Tech FL5," check the part number before you buy, because it's almost certainly the wrong fitment.
Real talk: Great value for a firmer, sportier street ride from a brand that's been doing this forever. A tier softer and more streetable than the Swift, a tier firmer than Pro-Kit.

AFD Dual-Rate Value

AFD (AeroflowDynamics) Sport Dual-Rate

Front Rate
Dual*
Rear Rate
Dual*
Type
Dual-rate
Drop F/R
-25mm / -25mm (1.0")

The budget entry. Even 1" drop, dual-rate construction that's soft on the street and firmer once you load it, powder-coated finish, and a lifetime warranty on paper. The pitch is a progressive-feeling ride at a lower price than the Japanese and German names.

Real talk: If budget is the deciding factor and you mostly want the stance plus a bit more control, these do the job. Just go in with your eyes open. AFD doesn't publish exact spring rates, and the value tier is the value tier. Buy from a real dealer, not some random marketplace listing, and you'll be fine.

Fortune Auto VHLS New / Height-Adjustable

Fortune Auto Variable Height Lowering Springs

Front Rate
4.4 kgf/mm
Rear Rate
5.0 kgf/mm
Type
Adjustable height
Drop F/R
0 to ~-32mm (0 to 1.25")

The clever middle ground between springs and coilovers, and a newer option worth knowing about. VHLS uses a threaded lower perch so you can dial ride height anywhere from stock down to about 1.25", while keeping your factory adaptive dampers and all three drive modes. Rates sit close to stock so the ride stays comfortable, and it's backed by a 5-year warranty. Sold in a shared FL5/DE5 fitment.

Real talk: If you can't decide how low you want to go, or you want to corner-balance and fine-tune later, this does what a fixed spring can't. You pay more than a standard set, but you're buying flexibility, and you keep the adaptive dampers you already paid for.

Alignment Notes

Whatever you install, budget for an alignment right after. This part isn't optional. Lowering the FL5 or DE5 pulls in negative camber up front and shifts your toe, and if you leave that uncorrected you'll chew the inside edges off expensive tires within a few thousand miles. Get it aligned to a spec that suits how you drive: closer to factory for even daily tire wear, or a little more front negative camber (with toe corrected) if you track it and want the front end to bite. Give any new spring a few hundred miles to settle before the final alignment, since ride height drops slightly as the springs seat in. And if you're going aggressive on the drop, have the shop make sure you're not riding the bump stops at rest. That's the fastest way to ruin the ride quality you just paid to improve.

Bottom Line

Just want me to tell you what to buy?

Most FL5 and DE5 owners should grab the Eibach Pro-Kit or H&R Sport. Proper drop, better handling, and a ride you'll still love on a long drive.

Want more character without punishing the daily commute? J's Racing or Spoon V2 are the balanced enthusiast picks.

Serious track use and you're okay with a firmer street ride? Swift Spec-R, Eibach Sportline, or TEIN S.Tech.

Want to set the height and forget it? RS-R Ti2000 for sag resistance, or Fortune Auto VHLS if you want to keep adjusting it yourself.

Tightest budget? AFD Dual-Rate, eyes open, from a real dealer.

There's no single best spring. There's the best spring for how you drive your car. Buy for that, get the alignment done, and go enjoy it. Got questions on fitment for your specific FL5 or DE5? That's what we're here for.
