Fitting and delivery

To fit the MTS Street A6 C4 Inox, 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.
• The adjustment range may differ depending on the version of the car, the lowering and the accuracy of the welding work on the suspension.
• After fitting the MTS Street A6 C4 Inox, 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 A6 C4 Inox combines stainless steel damper bodies, Eibach springs of 70 and 60 N/mm and up to 100 mm of lowering for the Audi A6 C4 / 100 C3/C4 / 200 C3.

Why choose the MTS Street A6 C4 Inox?

With the MTS Street A6 C4 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.

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 A6 C4 Inox is delivered within 4 to 7 working days as long as the manufacturer has stock.
