Q: What is Bead Knurling?
Bead knurling is a process used in the manufacturing of tire rims or wheel rims. It refers to the creation of textured or patterned grooves (knurls) along the bead seat area of the rim, where the tire’s bead (the inner edge of the tire) sits.
The purpose of bead knurling is to improve the grip between the tire and the rim, ensuring that the tire remains securely seated on the rim, especially under high pressure or during aggressive driving. This knurling creates small ridges or bumps that increase friction, which helps prevent the tire from slipping or coming off the rim in extreme conditions, such as during high-speed turns, braking, or sudden impacts.
Bead knurling is commonly found in high-performance and racing tires, where tire security and reliability are crucial. It can also be used for certain off-road vehicles or trucks, where the tires endure heavier loads and more rigorous conditions.
In short, bead knurling enhances the performance and safety of tires by ensuring they stay properly attached to the rim, even in demanding situations.

Simply love the design of this front splitter. Worked with Kirk on Monday evening, scheduled for pick up Friday morning in Hawthorne, and got it installed the same afternoon. Such a stunning piece, there’s nothing else like it in the market. I love it!

I have my model 3 performance and love it and now after adding these coil overs, can’t comprehend why these aren’t stock for tesla. These coil overs are amazing automagically felt like the car was on a cloud, handles great, and very smooth. Noise is reduced and can not believe I took this long...

These shocks are EXCELLENT. They totally transform the 1st gen Model S. My P90D felt very unbalanced and floaty on my factory struts, these shocks made it feel like a BMW M5...a totally different and improved driving experience.
I set these to 50% (2 turns out of 4 on the dampening key), and...

Beefy design, necessarily. Need the toe arms in conjunction with rear camber arms to dial in toe at the same time, otherwise toe will be out of spec when adding negative rear camber.

These nuts are awesome! So much lighter than the OEM and they look so much cooler. Reduces unsprung weight while looking cooler which is a win-win. I went with the burnt titanium finish which looks incredible and really adds some color to your wheels in a subtle way. Highly recommend.

This definitely helps cool down my drive unit quicker. I'm able to run a hot lap at the track, then a single cooldown lap to bring the drivetrain temperature back into the green. It was awesome seeing it cool down within a lap at Buttonwillow.
