Fitting and delivery

MTS Technik builds the MTS A6 C4 quattro 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 A6 C4 quattro, 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 A6 C4 quattro combines zinc-plated damper bodies, Eibach springs of 70 N/mm and up to 65 mm of lowering for the Audi A6 C4 / 100 C3/C4 / 200 C3 / V8 with four-wheel drive (quattro).

Why choose the MTS A6 C4 quattro?

With the MTS A6 C4 quattro 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. 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.
