Quick mod…..a mounting system that will work for my iPhone when on the street but also my Garmin Catalyst when on the track. A track friend of mine had this and I felt it was a cleaver solution so I copied it. Here is what you need.
Drill out the hole just a bit on the Rennline magnetic mount so you can use a bolt that fits the Ram 1” mounting ball
Peak Design 1” ball magnetic mount as the Rennline magnet is not strong enough. The Peak Design will also charge your iPhone. You can get cheap China knockoff versions on Amazon but I went with Peak Design as they are a quality company.
Any Ram double ball arm (there are a few different lengths and you can even do double arms if you want)
With this set up you can mount just about anything to the Rennline mounting plate. I decided to use the Peak Design magnetic charger for the street but then when I am on the track I can swap out the arm and mount the Garmin Catalyst.
