How do I adjust the rebound on these Koni shocks?

The rebound adjustment is external, meaning you can typically turn a knob or use a tool on the top of the strut insert to change the damping setting. This allows you to easily tune the suspension's response without disassembling the strut.

What is the difference between a strut insert and a complete strut assembly?

A strut insert is a self-contained damping unit that fits inside your original strut housing. A complete strut assembly typically includes the housing, spring, and mount all as one pre-assembled unit.

Do these Koni shocks come with new springs or mounts?

No, these are strut inserts. They are designed to be installed inside your vehicle's existing strut housing. You will reuse your original springs and mounts, or any compatible aftermarket replacements you may have.

Product Details

If you're looking to get more out of your 1988-1991 BMW M3's suspension, especially for spirited driving or track days, consider these Koni Sport (Yellow) front strut inserts. They're designed to replace your factory struts and offer a significant upgrade in handling and adjustability. These aren't just a simple bolt-in replacement; they're built to give you more control over your car's feel.

What sets these Koni shocks apart is their external rebound adjustability. This means you can easily fine-tune how quickly the shock returns after compression, allowing you to dial in the suspension for different driving conditions or tire setups. They use a twin-tube, low-pressure gas design, which helps maintain consistent damping performance even under demanding use. The yellow paint is a classic Koni look, and these are well-built units that many enthusiasts trust for improved road feel and cornering grip.

These inserts are specifically made for the E30 chassis, fitting the 318i, 318is, and M3 models from the specified years, excluding the M-Technik suspension and convertible models. Make sure to check the fitment details carefully for your specific vehicle. You'll be working with a strut insert, so installation involves removing the old strut assembly and installing this insert within the existing strut housing.
