Fitting and delivery

The MTS Street CLA X117 Inox replaces the original dampers and springs and fits on the original mounting points.

• 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.
• Tip for adjusting the rear: remove the height adjuster, set the spring seat to the new position and refit the adjuster.
• 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 CLA X117 Inox combines stainless steel damper bodies, Eibach springs of 50 and 110 N/mm and up to 40 mm of lowering for the Mercedes CLA X117.

Why choose the MTS Street CLA X117 Inox?

With the MTS Street CLA X117 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.

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.
