Fitting and delivery

To fit the MTS Street Polo 86 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.
• 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 Polo 86 Inox combines stainless steel damper bodies, Eibach springs of 50 and 30 N/mm and up to 85 mm of lowering for the Volkswagen Polo 86/86C / Derby.

Why choose the MTS Street Polo 86 Inox?

With the MTS Street Polo 86 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.

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 Polo 86 Inox is delivered within 4 to 7 working days as long as the manufacturer has stock.
