APEX WHEEL STUD KIT
Benefits of a Wheel Stud Conversion Kit
Try and find a BMW race car that hasn't converted to wheel studs yet with a stud conversion kit. They're stronger, safer, and improve pit stop times significantly.
For non-race cars, stud conversions still make wheel installation and removal much easier as you no longer have to line up the holes in your wheels, spacers, and hubs beforehand threading a single lug bolt through. Simply slide the wheel onto the studs, and let go. With lugs, an unsupported wheel will slip off the hub lip and fall onto the ground. With studs, there is enough length to float the wheel in place and in proper alignment. Sitting on the ground with your feet under the car, and supporting the wheel with your feet while you try and line everything up is a thing of the past.
Extended length wheel studs like these allow for a range of spacers to be used without any additional modification. You can easily use 3mm, 5mm, 10, and 12mm spacers with the 75mm studs. For 15mm, 18mm, 20mm, and 25mm spacers, the 90mm studs are required to allow for enough thread engagement. Either length kit can be used without spacers just as easily. When using lug bolts with spacers you are forced to purchase a different length lug for each width spacer as any spacer even 3mm thick is dangerous to use with the short thread OEM BMW lug hardware. Why own a bucket full of lugs when a single set of studs can do it all?
By remaining installed, studs will put less wear on the threads of your hubs. They guarantee there is enough thread engagement, as you can see how many threads were engaged during install.
Wheel studs replace your OEM lug bolts by simply threading into your car's hub. Once installed they do not need to be removed when changing or removing wheels. Only the lug nuts are removed similar to many domestic and import vehicles.

Sean arranged a Quaife LSD for my 135i and I couldn't be happier. He advised multiple seals and bearings needed replacing unbeknownst to me so these were done as well. Now I have a more reliable car and one with tonnes more mechanical grip!
My first dealing with Southern BM was a pleasant one. I had some springs and shocks installed and Sean was a delight to deal with. Knowledgeable, helpful and offered solutions when not everything went to plan. I would happily recommend them.
Thank you once again to John, Andrew and their team. Have been bringing our cars to them for several years now and have complete trust and faith in their workmanship and honesty.
Excellent service at reasonable prices. The shop is very nice too, you almost feel like you're at BMW.
