Fitting and delivery

To fit the MTS Street E9 Gold, the original front struts are shortened and welded as described in the manual. Have this done by an experienced mechanic or welder.

• 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 lowering, have the wheel alignment checked, because camber and toe change as well.

Delivery: 4 to 7 working days while manufacturer stock lasts.

The MTS Street E9 Gold combines zinc-plated damper bodies, Eibach springs of 70 and 30-70 N/mm and up to 100 mm of lowering for the BMW E9 Coupe.

Why choose the MTS Street E9 Gold?

With the MTS Street E9 Gold 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. The Gold version is the most affordable way to get an MTS Technik coilover kit, with a zinc coating that protects well against rust. If you also drive in winter, take a look at the Inox version with stainless steel damper bodies. With the included camber plates you set the camber, which with a large lowering means less tyre wear and more grip.

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.

Do the struts really have to be welded?

Yes. With this weld-in insert kit, your original struts are shortened and welded as described in the manual. If you don’t want to weld yourself, check whether a send-in kit exists for your car: with that, MTS Technik does the welding.

How long does delivery take?

The MTS Street E9 Gold is delivered within 4 to 7 working days as long as the manufacturer has stock.
