(Part 2) Top products from r/Autocross

I've used AIM data loggers and made my own arduino based accelerometer and GPS data acquisition systems; but lately I prefer the phone/tablet based GPS logging apps when paired with an external 10Hz+ GPS. IMO, the ability to easily review the data on the spot and provide immediate feedback and comparisons between runs far out weighs the bell and whistles of the more advanced systems that typically require plugging into a computer to review the data. Phone mounting is really not an issue if you get a good mount (I use a ram mount or [kenu airframe] (https://www.amazon.com/Kenu-Airframe-Universal-Accessories-Compatible/dp/B00D901B4W/ref=sr_1_6?ie=UTF8&qid=1501912932&sr=8-6&keywords=phone+vent+clip)).

I didn't like the high cost of Solostorm, so I prefer RaceChrono for it's simplicity, while some people like Harry's Laptimer. They will all give you speed, position, and accel from the GPS data. How they differ is in the user interface and presentation of the data. For overlaying data on video, I use [Dashware] (http://www.dashware.net/).

Regarding the actual data, I personally find the speed and position data more useful than just the long/lat accel data. Pro Tip: You'll gain a lot of insight by logging data of people faster than you.

We just put together a new racing line infographic. I really like these kinds of quick reference sheets that pack a lot of info into one graphic. Hope you like it.

The 3rd book in The Science of Speed Series is also now available. The Perfect Corner 2** covers complex track sections and completes our core program starting with The Perfect Corner and Perfect Control. Here is the Amazon link, but it's available from other retailers as well.

Feel free to ask questions as well.

For fluid, Motul RBF600: https://www.amazon.com/gp/product/B004LEYJO4/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

That's the best stuff that's reasonably priced that I've found. Most people I've asked about fluid run it as well.

As for pads, I've had good luck with Stoptech Street Performance, but I got them specifically for their inital cold-bite characteristics (since I'm usually on cold brakes). Don't use that link though, I don't think that's the right part number for the Miata.

But mainly the fluid change is the important part. On my FWD rallycross car it completely solved my fade issue (left foot braking for 1/3 of the lap is really hard on front brakes).

Sure. Here's the microphone: http://www.amazon.com/gp/product/B0016ARZ9C/ref=wms_ohs_product?ie=UTF8&psc=1

With a Hero 2, you just plug it in. With the Hero 3, you need the microphone adapter: http://gopro.com/camera-accessories/3-5mm-mic-adapter

I go with Ram Mounts. They are good, solid mounts that seem to be very well built. Assuming a GoPro, you could do the following:


Base: https://www.amazon.com/RAM-Mounts-Diameter-Suction-RAM-B-224-1U/dp/B008JGZMZK/


Arm: https://www.amazon.com/RAM-Mounts-Double-Socket-RAM-B-201U-C/dp/B00CU9BTKY


GoPro Adapter (don't buy the actual Ram Mount adapter because it's one of the very few things they make that isn't any good): https://www.amazon.com/Swivel-Lateral-Pattern-Adapter-Mounts/dp/B00PDHYG0K


If you're looking for a generic camera screw-type adapter: https://www.amazon.com/1-Inch-Diameter-4-Inch-20-Cameras-Camcorders/dp/B0056I8SLE/

Yeah, then I still need to make brackets mounting off something solid to screw into. Thats the hold up there.

Friend has offered me a set of these, from Sparco, that he had sitting around from his drift car... not sure yet.. http://www.amazon.com/iJDMTOY-Release-Fasteners-For-Car/dp/B00JJYPATO/ref=sr_1_fkmr1_1?s=automotive&ie=UTF8&qid=1404933893&sr=1-1-fkmr1&keywords=Sparco+quick+release+fasteners

Here's some in-car video using my Galaxy S4 and this mount: http://www.amazon.com/gp/product/B007FH716W/ref=oh_details_o02_s00_i00?ie=UTF8&psc=1

Ignore that I should have done a good chunk of this run in 3rd instead of 2nd. ;)

What I like about the mount is that the suction cup has a mild adhesive on it that you can "recharge" by rinsing it off. The clamps hold my phone very well. Not sure I'd be willing to stick my phone outside the car but it holds it very tight inside.

Also, this amazing hat for those sunny days: http://www.amazon.com/KAVU-Chillba-Pyrite-One-Size/dp/B002LFDWFM/ref=sr_1_23?s=athletic-clothing&ie=UTF8&qid=1417711330&sr=1-23

I went with a pair of these:

Etymotic ER20

I'll test them out beforehand. I've needed sound protection for various environments anyway, if they aren't useful for this I'm sure they'll be useful for something else.

HJC Helmets CL-17 Unisex-Adult Full Face Void Street Motorcycle Helmet (Grey/Neon Green, Large) https://www.amazon.com/dp/B01GR7KDZG/ref=cm_sw_r_cp_apa_DBiXBb4X8JHXV

HJC 824-584 CL-17 Full-Face Motorcycle Helmet (Matte Anthracite, Large) https://www.amazon.com/dp/B00FE1X7AU/ref=cm_sw_r_cp_apa_.BiXBb92H8PSX

Would any of these work. I was looking more for a full helmet.

I think it is the baked in image stabilization. It does look weird now that I look at it!

It is a garmin Virb on a Fat Gecko mount suctioned onto the moon roof glass.

I use the Panavise suction cup mounts with my FlipHD camera occasionally.

I've never worried about it falling off. I've attached it to the sunroof, the actual roof, the windshield, the front fender, and the back hatch of my WRX and had no problems. I've used it at highway speeds and while racing with the SCCA.

If you can find something similar to hold the Nexus securely I think it should work. Depending on your car though, there may be a bunch of vibrations on the sunroof glass that could distort your video.

TrackAddict app and this OBD2 bluetooth transmitter is what I have used. I don't mount the phone to get accelerometer data. I don't have external GPS either but TrackAddict recommends this. 1 hz internal phone GPS is kind of crap. I'm going to get a Garmin Virb Ultra 30 which does video, 10hz GPS, has accelerometers, and can connect to OBD2.
