  1. gnamaka (verified owner) –

    Bought this conversion stud kit to add aftermarket wheels to my 2020 BMW X5 (G05) . Product is top notch (Grade 12.9 hardness is stronger than all other options out there) fit and finish were perfect and product installed and works flawlessly. I also had some after purchase questions and Ryan was amazing at providing additional support. Product and Ryan from Motorsport Hardware are above and beyond. Will definitely order again from them!

  2. Tyler Gilbert (verified owner) –

    great product and great customer service. 78mm looks great on my f30 with 12.5mm spacer in the front and 17.5mm in the rear

  3. rey.cwfl –

    Thank You Ryan, just what I was looking for to get my Supra a little more functional and up to date. Fitment was great and ease of installation. I will be definitely buying more in the near future. Thank you again for all the help.
