What is the main benefit of a progressive spring rate?

A progressive spring rate means the spring's stiffness changes as it compresses. This allows for a comfortable ride during normal driving conditions and provides increased support and control when the suspension is working harder, like during cornering or over bumps.

What does 'shot peened' mean for these springs?

Shot peening is a process where small beads are blasted at the spring's surface. This creates a stronger, more resilient material by inducing compressive stress, which helps the spring resist fatigue and cracking over time.

Do these springs come with new bump stops or hardware?

This product listing is for the H&R OE Sport Springs only. It is recommended to inspect and potentially replace associated suspension components like bump stops and hardware during installation, as they are not included with the springs.

Product Details

Made from strong 54SiCr6 spring steel, these H&R OE Sport Springs are built to last and offer a noticeable improvement for your 1987-1991 BMW 325i. If you're looking to get a bit more out of your E30's suspension without sacrificing too much comfort, these springs are a solid option. They're designed to give you a slight lowering, which helps reduce body roll during cornering, making your car feel more planted on the road.

The progressive spring rate is a key feature here. It means the springs get stiffer as they compress, offering a good balance between a comfortable ride during normal driving and improved control when you push the car a bit harder. This updated design helps maintain a superb ride comfort while giving you better handling and performance. Plus, they are shot peened and block set for added resilience, and 100% made in Germany.

These springs are intended for the 325e, 325i, and 325is models, specifically excluding the Cabrio and ix variants, as well as the M3. They offer a subtle upgrade that really fine-tunes the driving experience, giving you that slight increase in handling and control you're looking for.
