ECS BMW Wheels - Genuine & Performance for BMW E21 320i M10 1.8L

Clear BMW chassis

Please ensure your correct model is selected

The wheels and stance often make the look of the car complete. If your factory alloys are missing center caps, curb-rashed beyond recognition, or have been damaged, we have your replacements all picked out. For a performance-oriented driver, aftermarket alloys shed weight and offer improved aesthetics over the factory options. Space out your stance with our selection of wheel spacers, completely change the look and feel of your BMW with forged or flow-formed aftermarket alloys, or replace old wheels with factory options.

These wheel locks are made in extended lengths to work with wheel spacers. This is the standard conical seat bolt in a 12x1.5 thread pitch (most BMWs up to 2012). This is a set of 4 bolts - one bolt per wheel that replaces one of your existing extended wheel bolts. The 9 point socket provides an extra layer of protection for your coveted wheels. Black zinc coating resists rust and corrosion. Choose the wheel locks to work with your wheel spacers from the list below.

Unsure of what size spacer will work best for you? This professional kit includes 1mm, 2.5mm, 5mm, 10mm, and 15mm spacers with wheel studs and nuts for you play with. These are not the same spacers that we sell and they cannot be used to drive on. But with the studs installed the car can be lowered to the ground and rolled to check for clearances. These test fit spacers are drilled to fit the standard BMW 5x120 bolt pattern as well as 4-lug 4x100 (and VW/Audi bolt patterns too). You can stack spacers to achieve the perfect clearance. When you're ready call us to order the spacers you need (Turner spacers come in 3mm, 5mm, 7.5mm, 10mm, 12.5mm, 15mm, 17.5mm, 20mm, 25mm, and 30mm spacer thicknesses).

These spacers are not for driving on. They lack the hubcentric lip that BMW wheels are designed to work with. Driving on studs alone will lead to a failure.

Two ways to buy -

  • Own. Just as it says, you buy this kit to own. Perfect for shops or race teams that change wheels or brake components often. For shops you can measure wheel clearance and order the correct spacers the first time around (no wasting inventory or paying return shipping). Note: Kits purchased to Own are not returnable for refunds.
  • Rent. Pay the full price but get $110 as a store credit when you return the kit. We keep a modest $19.95 fee for the service. Perfect for DIY and enthusiasts who only need the Test Kit once. Use your store credit to purchase your spacers (or anything else from our catalog).

Unsure of what size spacer will work best for you? This professional kit includes 1mm, 2.5mm, 5mm, 10mm, and 15mm spacers with wheel studs and nuts for you play with. These are not the same spacers that we sell and they cannot be used to drive on. But with the studs installed the car can be lowered to the ground and rolled to check for clearances. These test fit spacers are drilled to fit the standard BMW 5x120 bolt pattern as well as 4-lug 4x100 (and VW/Audi bolt patterns too). You can stack spacers to achieve the perfect clearance. When you're ready call us to order the spacers you need (we make 3mm, 5mm, 7.5mm, 10mm, 12.5mm, 15mm, 17.5mm, 20mm, 25mm, and 30mm spacer thicknesses).

This kit is for purchase only. It's perfect for shops or racecars where changing wheels or brakes is common. We also have kits that are available for rent.

These spacers are not for driving on. They lack the hubcentric lip that BMW wheels are designed to work with. Driving on studs alone will lead to a failure.
