The MTS Street E3 Inox is a height-adjustable send-in kit (coilover) from MTS Technik for the BMW E3 Sedan, model years 1968 to 1977. Street is the standard setup from MTS Technik: a good balance between comfort and firmness.

On the Inox version, the damper bodies are made of stainless steel, so road salt and moisture don’t stand a chance. This is a send-in kit: MTS Technik builds the kit with your own original front struts, so you don’t have to weld anything yourself.

Fitting and delivery

MTS Technik builds the MTS Street E3 Inox with your own original front struts: after receipt they are stripped of their paint, welded to size and zinc-plated.

• The stated lowering applies relative to the standard suspension. If the car has a factory sport suspension, the lowering will be smaller.
• When fitting, check the clearance between tyre or wheel and the strut: at least 5 mm. If it is less, use approved wheel spacers.
• After fitting the MTS Street E3 Inox, have the wheel alignment checked, because camber and toe change as well.

How a send-in kit works

• After your order we will email you the shipping instructions and the address for your original front struts.
• Beforehand, remove all parts from the struts, such as hubs, bearings, cover caps, damper cartridges, bolts and nuts. If the struts arrive not disassembled, or if damage is found (for example broken bolts), they will be sent back or extra costs will be charged.
• Send in the struts in their original paint, even if it looks bad. Do not spray or paint them beforehand; they are stripped, welded and then zinc-plated.
• Because the kit is made to measure with your struts, the right of withdrawal for distance purchases does not apply: a send-in kit cannot be returned.
• This kit is only delivered within the European Union.

The delivery time depends on when your struts arrive. After your order we will keep you updated by email about the dispatch and the expected delivery time.

The MTS Street E3 Inox combines stainless steel damper bodies, Eibach springs of 70 and 60 N/mm and up to 85 mm of lowering for the BMW E3 Sedan.

Why choose the MTS Street E3 Inox?

With the MTS Street E3 Inox you choose the setup MTS Technik itself recommends as standard: enough lowering for a tight stance, and a character that doesn’t become tiring on the road. If you also drive in winter or the car is parked outside, the Inox version pays for itself: stainless steel doesn’t rust, so the thread of the height adjustment doesn’t seize up. If you mainly drive in summer, the Gold version is a more affordable alternative. With the included camber plates you set the camber, which with a large lowering means less tyre wear and more grip. And because it is a send-in kit, you don’t have to weld anything yourself.

Frequently asked questions

What is the difference between Gold and Inox?

Gold has steel damper bodies with a yellow zinc coating, Inox has stainless steel damper bodies. Inox is more resistant to road salt and moisture and therefore costs more. Otherwise, the kits are identical.

Can I return a send-in kit?

No. Because the kit is made to measure with your own struts, the right of withdrawal for distance purchases does not apply.

How long does delivery take?

The delivery time of the MTS Street E3 Inox depends on when your struts arrive. After your order we will keep you updated by email about the dispatch and the expected delivery time.
