KnifeySpoony Posted August 7, 2021 Share Posted August 7, 2021 (edited) So I have been searching around for the best option for phone mount (which I also use for laptimer on track) for my newly built 420R. I have an aeroscreen, so no suction cup to windscreen. I was hesitant to put a suction cup on the dash, even though that would probably work. It just feels so flimsy and I was worried about the phone bouncing around and damaging the dash. I also looked in the 3d printed holder available on ebay: https://www.ebay.co.uk/itm/293979086187. However this would block gauges. Then I realized there was a tube on the passenger side meant for RHD steering columns I assume. I got a RAM mount clamp (small size): https://www.rammount.com/part/RAP-B-400U. It clamps securely to this small section of tubing, and the system works great, as long as you don't have a passenger (which I rarely will) Edited August 7, 2021 by KnifeySpoony Link to comment Share on other sites More sharing options...

kayentaskier Posted August 7, 2021 Share Posted August 7, 2021 Yes Thanks. Am I correct to assume you ordered: RAM® Tough-Claw™ Small Clamp Base with Ball B SIZE: Part#: RAP-B-400U UPC: 793442943539 RAM® Double Socket Arm B SIZE B Part#: RAM-B-201U-A UPC: 793442002649 RAM® X-Grip® Large Phone Holder with Ball B SIZE Part#: RAM-HOL-UN10BU UPC: 793442940873 Link to comment Share on other sites More sharing options...
KnifeySpoony Posted August 8, 2021 Author Share Posted August 8, 2021 I think so- I don't recall the part names for the arm and xgrip as I've had them for years. Only the clamp is new for this application. For those that don't want to intrude too much on passenger space, you could add another arm or two to bring the phone up and/or closer to the driver. I haven't tested the reach to the phone with harnesses on (as in to start my lap timer). If I can't reach it, I may extend with the additional arm(s). I have never read about anyone using this tube to clamp on, so I thought I'd share, as it seems among the most secure ways to secure a phone mount.

Croc Posted August 8, 2021 Share Posted August 8, 2021 @KnifeySpoony Excellent idea - thanks for posting. Most people have no idea that mount point is there as they have never enjoyed the 'pleasures' of hanging upside down in a footwell. Have you tried it on track? All secure even in high G corners?

KnifeySpoony Posted August 8, 2021 Author Share Posted August 8, 2021 First trackday is next weekend (just got to 500mi and first oil change). I have no doubts about it being secure. It's on there tight. Link to comment Share on other sites More sharing options...
KnifeySpoony Posted August 18, 2021 Author Share Posted August 18, 2021 Holder did great at the track. A (smallish) passenger even rode a long one session and it wasn't in their way. I should mention that this solution only works if you don't have the fuse box cover there, as it blocks this piece of tubing. Link to comment Share on other sites More sharing options...

John B Posted September 7, 2021 Share Posted September 7, 2021 Nice video! What is the Lap timer App you were using? Does it work off GPS or does it need a beacon? Link to comment Share on other sites More sharing options...
KnifeySpoony Posted September 8, 2021 Author Share Posted September 8, 2021 App is RaceChrono. It can use the cellphone GPS, but at 1Hz, the performance is not ideal. I'm using a standalone Garmin 10Hz GPS unit via bluetooth. Link to comment Share on other sites More sharing options...
fastg Posted September 8, 2021 Share Posted September 8, 2021 I also use RaceChrono, with a Bluetooth ODB2 and a Bluetooth Garmin GLO external GPS receiver. The GLO made a huge difference, before the mapping looked like it was drawn by a 5 year old with a crayon, with the GLO you can see you actual parking spot in the paddock. I do not chase lap times, I have found that to be counter productive. I fire it up then switch the screen off. I email the logs to my tablet so they are easier to review later in the hotel.
