Description

Fitting and delivery
To fit the MTS Street E12 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.
- Only fits with a rear top mount with an inner diameter of 78 mm (OE 33521117657 or 33521126987). If the car has different top mounts, original top mounts with one of these numbers are required.
- On cars with level control (NIVO), the rear top mounts must be replaced with OE 33521117657 or 33521126987.
- After fitting the MTS Street E12 Gold, 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 E12 Gold combines zinc-plated damper bodies, Eibach springs of 60 and 50 N/mm and up to 100 mm of lowering for the BMW E12.
Why choose the MTS Street E12 Gold?
With the MTS Street E12 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 E12 Gold is delivered within 4 to 7 working days as long as the manufacturer has stock.
