Thanks for the video. I only get to drive in Assetto Corsa (but at least in vr) so it's so much fun to see the track in "real life". I like the track because..well..it's a fun track but also because it's so short. If you screw up you won't have to drive for more than a minute until the next lap starts.

that's definitely true! it's the easiest track I've driven so far

Good lapping! I’m thinking about a 4.8 FD with a 1.5 way LSD which is what all the top dogs use in their 86. Our tracks are more technical tighter than this though.

that would be awesome! I've thought about doing the same but I think it would be one of the last mods I would do to my brz just bc of the cost

Good lap. IMO there was time in 2 thru 3 on that lap. You lifted and touched the brake then had to modulate the throttle. To me this means you are missing your turn in speed and minimum apex is too low. Ideally you want to allow the car to slow down all the way through track out so it will take a set and you can power up through 3. And turning the car is slowing it down. Watch “Matt Wasileeski NASA ST4 Trim Best/Fast Lap” and he’s textbook through that section IMO.

Thanks for sharing! What specific data acquisition would you think is the first item to get for HPDE?

def a gps! that will basically meet all your needs and if you wanted extra info like brake/throttle traces you could pair that with an obd2 reader. I have a whole video dedicated to this topic if you're interested: kzfaq.info/get/bejne/o8p3gtiZqteal2w.html
