What to Know Before You Buy
335i vs 335Xi
The 335i (RWD) and 335Xi (AWD) have different front suspension geometry. The H&R Sport (50490-4) and Race (50490-88) in this guide fit RWD 335i Sedan only. For 335Xi, use the H&R 50494 kit designed for xDrive models.
Vehicle Age & Shock Condition
2007–2011 E90s are 14–18 years old. Factory shocks are likely worn. Installing new springs on tired dampers can feel bouncy. Consider Bilstein B6 or B8 when installing springs for the best ride quality.
Alignment & Camber
Drops under 1.3" (H&R Sport, Swift) typically stay within factory alignment specs. The H&R Race (-2.0" front) will require camber plates or adjustable arms for optimal tire wear. Always budget for a professional alignment after installation.
N54 Platform
The 2007–2011 335i uses the N54 twin-turbo inline-six. The E90 sedan shares suspension components with the 328i Sedan. Spring kits designed for 328i/335i Sedan E90 (07-11) will fit your 335i.
H&R Sport Springs
The H&R Sport (50490-4) delivers a 1.3" front and 1.2" rear drop on the 2007–2011 BMW 335i Sedan E90. Designed specifically for the RWD 335i, it provides a balanced stance with a progressive spring rate that maintains daily comfort while reducing body roll and improving turn-in. The most affordable option in this guide.
H&R springs are cold-wound from 54SiCr6 steel in Germany. Forum feedback from E90 335i owners is consistently positive — the Sport sits lower than stock without the harshness of the Race springs. Ideal for daily-driven 335is.
Drop by Application
| Application | Front Drop | Rear Drop |
|---|---|---|
| 2007–2011 BMW 335i Sedan E90 | -1.3" | -1.2" |
Pros
- Lowest price in this guide
- Balanced drop for daily driving
- Progressive rate for street comfort
- Made in Germany
- Strong community validation on E90
Cons
- RWD only (no 335Xi fitment)
- Less aggressive than H&R Race
H&R Race Springs
The H&R Race (50490-88) delivers the largest fixed drop in this guide: 2.0" front and 1.5" rear on the 335i Sedan E90. The same kit fits 328i Sedan (07-11) and 335i Coupe E92 (07-13). The aggressive drop reduces fender gap significantly but uses a firmer progressive rate.
Camber correction is strongly recommended at -2.0" front. The Race is ideal for owners who want maximum stance without going adjustable. Made in Germany. At the same price as the Sport, it's a value choice for those who prioritize drop over comfort.
Drop by Application
| Application | Front Drop | Rear Drop |
|---|---|---|
| 2007–2011 BMW 335i Sedan E90 | -2.0" | -1.5" |
Pros
- Largest fixed drop (-2.0" F)
- Same price as H&R Sport
- Made in Germany
- Fits 328i and 335i Sedan E90
Cons
- Firmer ride than Sport
- Camber correction required
- May scrape on steep driveways
Swift Spec-R Lowering Springs
The Swift Spec-R (4X905R) is the only linear-rate spring in this guide, designed for track-oriented 335i owners. It delivers a 1.0" front and 0.8" rear drop — the most conservative in this guide but tuned for optimal suspension geometry within the OEM shock's usable stroke. Fits both E90 Sedan and E92 Coupe 335i.
Swift's H5S.TW proprietary material aims to reduce unsprung mass and eliminate coil bind. The Spec-R is popular with HPDE and SCCA competitors. Japan-made. Best choice if you prioritize handling predictability over maximum drop.
Drop by Application
| Application | Front Drop | Rear Drop |
|---|---|---|
| 2007–2013 BMW 335i E90/E92 | -1.0" | -0.8" |
Pros
- Linear rate — predictable for track use
- Most conservative drop — no camber correction needed
- Fits E90 Sedan and E92 Coupe
- Japan-made, track-validated
Cons
- Firmer than progressive springs on street
- Less aggressive drop than H&R options

Common Questions
Frequently Asked Questions
Do I need new shocks when installing lowering springs?
Not required, but recommended. E90 335is are 14+ years old; factory shocks are likely worn. Installing new springs on tired dampers can feel bouncy. Consider Bilstein B6 or B8 when installing springs for the best ride quality.
Will lowering springs void my factory warranty?
2007–2011 335is are well past factory warranty. Under the Magnuson-Moss Warranty Act, a dealer cannot void your entire warranty for aftermarket parts, but warranty claims related to the modification can be denied.
Do lowering springs affect ride quality?
Yes. Conservative drops (Swift at -1.0" F) maintain near-stock comfort. Aggressive drops (H&R Race at -2.0" F) are noticeably firmer. Pairing springs with worn dampers will make any kit feel harsh.
I have a 335Xi. Which kits fit?
The kits in this guide fit RWD 335i only. For 335Xi (AWD), use the H&R Sport 50494 designed for 325Xi/328Xi/335Xi Sedan. The suspension geometry differs between RWD and xDrive.
