Bilstein B12, B14, B16 and EVO: Reading Bilstein's Product Names
Bilstein B14 vs B16 comes down to damping. The B14 PSS has fixed damping with adjustable ride height, and the B16 PSS adds damping you can adjust. Bilstein now calls its EVO T1 the successor to the B16, and the B12 kits are not coilovers at all.
Bilstein names confuse a lot of buyers. A B12 looks like a step below a B14, so people assume it is a simpler coilover. It is not. The numbers describe different kinds of product, and the EVO line adds a new set of letters on top. Here is how to read them, and which ones we list.
How Bilstein's Numbers Work
Bilstein invented the monotube damper, with a patent dating to 1957. Every name in its performance range builds on that damper, but the numbers tell you what else comes in the box.
B6 and B8. Shocks and struts only. The B6 replaces the factory damper at stock height. The B8 has a shorter body for cars on lowering springs. Damping is not adjustable. You may also see B4, B5, B7 and B9 shock listings; check each one's description.
B12. A matched package of Bilstein dampers and lowering springs. You get a set drop, not an adjustable ride height.
B14 PSS. The entry coilover. PSS stands for Performance Suspension System. Ride height adjusts, damping is fixed.
B16 PSS. A coilover with adjustable damping and adjustable ride height.
EVO. The newer coilover line. Bilstein says EVO stands for evolution, and that S, SE and R stand for Street, Street Electronic and Race. T1 and T2 are the track-capable kits.
B12 Pro-Kit and B12 Sportline: Lowering Kits, Not Coilovers
Most of the Bilstein listings on our site are B12 kits. They sit in the coilover section because they change ride height, but they work like lowering springs with matched dampers.
The B12 Pro-Kit pairs Bilstein B8 shocks with Eibach Pro-Kit lowering springs. The B12 Sportline is the lower of the two packages. Dealers describe it as a lower, more aggressive stance. We list B12 Sportline kits mostly for VW, BMW and Audi platforms, like the 2009-2016 Audi A4 Avant B12 Sportline listing.
A B12 makes sense when you want a fixed drop and nothing to adjust. If you want to set your own height or corner balance the car, you want a coilover kit instead. Our guide on coilovers vs lowering springs walks through that choice.
Bilstein B14 vs B16: What Changes
Both are threaded-body coilovers. Both let you set ride height. The difference in the Bilstein B14 vs B16 question is the damper.
The B14 PSS has fixed damping. Bilstein sets the valving for the car, and you cannot change it. That suits a street car where you want the stance and the control without a knob to think about.
The B16 PSS adds adjustable damping, so you can firm it up for a track day and back it off for the drive home. Bilstein's own EVO T1 page now calls the T1 the successor to its B16 threaded ride height adjustable kit. Our catalogue does not list B16 kits right now. If you want one for an older car, call and we will check what Bilstein still supplies.
We list well over a hundred B14 PSS fitments. Examples include the 2016-2025 Miata MX-5 ND B14 PSS listing and the 2013-2020 and 2022-2026 Subaru BRZ. We also list the 2000-2009 Honda S2000 and several E46 and F30 BMW 3 Series kits. Each title names its own years, trims and exclusions.
Fixed damping is not a weakness on the street. Plenty of drivers never touch their adjusters after the first week. If you know you will tune, look at the EVO T1 or T2 instead. Our guide to adjustable coilovers covers who benefits from the knobs.
Setup on a B14 is short. Set ride height, tighten the locking collar and get an alignment. Since the damping is fixed, the spring rate and valving Bilstein chose for your car do the rest. If the ride feels wrong after a week, check tire pressures and the alignment before you blame the dampers.
The EVO Line: S, T1, T2 and SE
EVO S. The street kit. Bilstein describes stepless lowering for sporty road driving that keeps comfort. We list it for the G20 3 Series and G22 4 Series, without electronic suspension.
EVO T1. Bilstein says it adjusts in ten clicks, with rebound and compression adjusted together. It is aimed at everyday use and the track. We list it for G20 and G22 BMWs, the Audi RS5 (F5) and the 2020-2026 GR Supra EVO T1 listing.
EVO T2. Bilstein's 10×10 Pro-Click adjustment lets you set rebound and compression separately, with two aluminum adjustment wheels. Bilstein calls it a track performance suspension. We list it for the G20 3 Series and the 2021 G22 430i.
EVO SE. Built for cars with factory electronic damping. Bilstein describes it as plug-and-play with the car's own electronic controls. We list it for G20 and G22 BMWs with electronic suspension and several 992 Porsche 911 models with PASM.
Bilstein also features an EVO T2 for the BMW M2 G87. We do not list that kit. Call us if you own one and we will check.
Which Bilstein Fits Your Build
Forget the numbers for a minute and start with how you drive. Each Bilstein line answers a different need.
A Daily Driver That Sits Lower
A B12 Pro-Kit or Sportline gives you a fixed drop with matched damping. Nothing to adjust, nothing to set up beyond an alignment.
A Street Car You Want to Fine-Tune for Height
The B14 PSS or EVO S lets you choose your ride height while Bilstein sets the damping. Most street builds land here.
Weekend Track Days
The EVO T1 adds damping adjustment in one wheel. The EVO T2 splits rebound and compression, so you can tune each one.
Factory Electronic Damping
The EVO SE keeps the car's electronic damper controls working. Check the listing for your exact model first.
If you are torn between the B14 and a coilover kit with damping adjustment, think about how often you will actually turn a knob. Be honest. Most Bilstein B14 vs B16 debates we hear end the same way. The driver picks the kit that matches the next twelve months of driving.
Reading a Bilstein Listing Title
Bilstein fitment is precise, and our titles carry that detail. Read every word before you order.
Words That Decide Fitment
"Without Electronic Suspension" or "Without Self-Leveling Suspension" means the kit is not for cars with those systems. "With PASM" or "Without PASM" splits Porsche fitments. On the 992 EVO SE listings, the split is with or without Front Axle Lift. Check which your car has. Some titles name a front strut diameter, such as 55mm, or a chassis number range. The GR Supra EVO T1 title notes that cars with electronic suspension need a separate canceller kit.
If anything in the title does not match your car, stop and check. Confirm on the product page, or call 1-800-460-9106 with your VIN.
Where Bilstein Sits Among the Brands We Carry
Bilstein brings OE-supplier credibility through Mercedes-AMG, BMW M and Porsche damper programs. Its B-numbered hierarchy, B6 through B16 PSS, is anchored by the monotube damper invention dating to 1957.
Other brands solve the same problem in their own way. BC Racing builds nitrogen-charged monotube coilovers with 30-click simultaneous compression and rebound on the BR Series, and Swift Springs SPEC-R upgrade springs on most fitments. KW V1, KW V2 and KW V3 use twin-tube dampers in stainless steel bodies. Fortune Auto hand-builds each kit in Virginia with custom valving.
Whichever brand you pick, the basics of performance suspension do not change. Spring rate and damping decide how the car rides. Unsprung weight comes from the wheel, tire, hub and brakes, so a coilover alone does not cut it. After any ride height change, align the car and check that every locking collar is tight. Our monotube vs twin tube guide explains why Bilstein and KW build their dampers differently.
