BMW i3 & i3S AST Suspension Lowering Springs

Upgrade Your BMW i3 & i3S With The AST  Lowering Springs That Drops Your Vehicle Whilst Maintaining Ride Comfort.

By lowering the centre of gravity, AST Lowering Springs reduce body roll and increase cornering stability which results in a car with much more predictable handling.

AST Lowering Springs are designed as a direct replacement for the cars original springs and have been developed for each specific vehicle. Made from cold wound premium high tensile chromium-silicone wire.

We have AST lowering springs installed on our very own shop i3S. The ride height drop helps reduce the large arch gap while lowering the centre of gravity to give much better road handling and high speed stability.

Lowering drop – 25mm+/-

Top Mount Replacement

Having worked on a huge amount of BMW i3 and i3S over the last few years we have noticed that the top mounts (Top part of the coilover) are starting to wear through which can affect how the vehicle drives and performs. At the same time as doing your suspension upgrade we can supply and fit replacement top mounts (Front Only or Front & Rear) with no additional labour cost if we’re installing this upgrade for you. Typically if your i3 has done over 30,000 miles we would recommend replacing the fronts. If you have done over 60,000 miles we would recommend replacing both front and rear. These can be chosen as an options whilst placing your order. For more information on these top mounts, please see the linked products at the bottom of this listing.

The replacement top mounts will be the genuine BMW versions with all new fixings.

Installation

We’re happy to offer this system for installation at our workshop here in Poole, Dorset.

Installation of this system takes approximately 4-5 hours. The price for installation covers for the suspension to be installed along with our signature 4-wheel alignment. This can either be a standard OEM or Fast Road Setup. Please note that if stuck or seized components are encountered at the time of installation (For example seized track rod ends) then there may be an extra charge required to cover this additional time.

If you opt for Supply Only, we would highly recommend installation by a trained technician / mechanic with the relevant experience. You must also ensure that your vehicle is aligned correctly post installation for safety.
