BMW Wheels - Genuine & Performance for BMW 3 Series E30 (1984-1991)

Upgrade your BMW with APEX wheels, renowned for their superior strength and lightweight construction achieved through the innovative Flow-formed semi-forging process. These wheels boast an impressive average weight reduction of 10lbs or more, enhancing performance by reducing unsprung weight. Engineered with spacious spoke and barrel design, they provide ample room for brake systems while maintaining a classic motorsports aesthetic that perfectly complements the aggressive BMW style. With APEX wheels, your BMW will not only look its best but also perform with confidence on the road.

• Enhanced strength and lightweight performance
• Innovative Flow-formed semi-forging process
• Average weight reduction of 10lbs or more
• Ample room for brake systems
• Classic motorsports design matches BMW's aggressive style

Apex EC-7 18x8.5" Square Wheel Set

Apex 8.5" wheel set for the front and rear of your BMW. These are a bit wider than stock to put more rubber to the road. This helps to reduce understeer on cars with staggered wheel sets and gives you the option to rotate tires. If you're tracking your BMW you should absolutely have a square wheel set (the same size front and rear). Adding a wider wheel will get you more rubber where it counts - reducing understeer and improving initial turn-in. We have put this wheel set together using four APEX 8.5" wheels in a ET45 offset. A 8.5" wheel allows for 225-245 R-comp or performance tires.

APEX light alloy wheels are the next evolution in flow-forged wheel technology for BMWs. Flow-forming is a semi-forging process that produces a wheel typically stronger than a traditional cast wheel yet is still light weight. The wheels are around 10lbs lighter per wheel than a comparable factory wheel! That's reduced unsprung weight that improves all aspects of performance. The spokes and barrel have been designed to allow generous clearance for big brakes. In other words, these wheels are very impressively engineered and look great too! The design is based on classic motorsport themes that blend with BMW styling and appearance. These wheels look right at home on many BMW models. Multiple color and profile options allow you to set just the right look and stance for your car. As well as being pleasing to the eye these are very strong and functional wheels that are at home on the street as well as the racetrack. Don't let the price fool you - these wheels are high quality, high strength, and in high demand.

Note: careful consideration of wheel width, offset and tire sizing must be observed when choosing and installing larger wheels. Adding larger wheels may lead to rubbing on suspension components or bodywork. Wheel spacers, new alignment settings, inside fender modifications, or other adjustments may be required.

BBS Wheels combine decades of race proven quality and German engineering with stunning good looks. Utilizing the most cutting-edge manufacturing technologies based on a foundation of constant innovation continues to propel BBS into the future.

RG-R style wheels combine a lightweight forged construction with an eye-catching yet tasteful design to bring you some of the finest two-piece wheels on the market. 

Forged wheels are created by crushing a solid block of aluminum into the desired shape using an extreme amount of pressure. This creates a wheel that is incredibly strong while remaining relatively lightweight. Using FEM analysis the engineers at BBS are able to precisely measure and optimize wheel properties before this process even begins. Once the forging process is complete, the meticulous finish work begins.
Back-milling is a process used to optimize the ratio between weight and stability. Using advanced computer analysis and a special CNC milling process the lateral parts that hold the wheel spokes, and are not relevant for stability, are removed. Extensive real-world simulation is used at this point to further ensure that no strength or stability has been lost.
Finally, BBS pays special attention in machining the undercut or back side of the wheel. To machine the undercut, all areas on the inner side of the wheel and the star hub that correspond to weight optimization are processed with special turning or milling tools and excess material is removed to reduce the rotating wheel mass. Special attention is hereby given to the optimization of the inner sides of the spokes and the bolt circle. With the application of these methods, BBS is able to produce more complex forms with increased stability and less material input.
These wheels come in a Diamond Black painted finish with a diamond cut lip and BBS ensures that their paint quality exceeds OE manufacturer specifications for durability and longevity. A final protective clear coat layer ensures that these wheels will be easy to clean and look amazing for years to come.

Please Note: Aggressive fitment, may require fender rolling/pulling.

Wheel studs are among the safest and most beneficial upgrades you can make on a track car. Not only are wheel studs safer than wheel bolts but they make changing wheels/tires much easier. One of the frustrating things about installing your wheels on the hub is that it's difficult to line up the wheel on the bolt holes. As wheels get larger but also heavier it's even more trouble. Add in a wheel spacer and the task is twice as hard. BMW does produce a wheel alignment pin for this purpose but if you're changing wheels often a stud conversion is the better way to go.

MSI Racing specializes in hardware for motorsports and other advanced industries and their wheel studs are some of the very best in the professional motorsports world. MSI is already a major supplier to teams in the top NASCAR categories and we tried them on our Grand-Am/IMSA racecars and were very impressed by the performance and durability of their designs. After testing them over the course of a few endurance seasons we decided to offer them to all of our customers as well. These studs are available in multiple lengthsand all sizes are made with aircraft quality material and have roll formed threads. The coating is a dry film lubricant HM-30 coating containing Teflon & Moly over a manganese phosphate finish. This coating process reduces friction and wear to prevent thread galling. Another benefit is that these have the best corrosion resistance we have seen in any wheel stud! A dry lube stud has the most corrosion resistance than a plain black coating because the lube is applied over the black phosphate coating. Salt tests have shown this stud is superior to others in corrosion resistance. Other features of our MSI studs include a large bullet nose nut-starter and a properly sized shank to work with a wider range of BMW wheel, nut, and brake rotor combinations.

These studs are the perfect choice for endurance racers, sprint racers, track-only cars, or even hardcore street cars. The bullet nose on this stud is deeper than other studs we have used. More of the stud protrudes through the open nut so that everything lines up better on the threads. This helps to eliminate the possibility of cross-threading or thread stripping. In addition, the shank has been machined for proper brake rotor alignment. The dry lube helps the nut engage and glide over the threads for faster pit stops without cross threading or binding.

Not all wheel studs are created equal. We don't take a manufacturer's generic wheel stud from their catalog and call it our own. Turner Wheel Studs are designed to our own specifications and manufactured for us exclusively. Beware of cheaper studs on the market! We have seen other studs similar to our own designs that are not a true BMW fitment. There are differences that we have ironed out over our years of selling wheel studs for the BMW market. Our stud prices may be slightly higher than the rock bottom prices on the web but we promise that it's a higher quality.
