I've only visited Portland to watch an Indycar race there but it looks like it'd be fantastic in just about any class of car.

I went to an autocross event yesterday where they charged about a hundred bucks, but there was no course work required and we got literally dozens of runs. Is this common? It makes way more sense to me than paying $30 but having to commit to being there all day, work the course, and only getting a couple of runs.

They do that at a local kart track here but it's like $60 or so. Getting to get a bunch of runs in and not work is definitely very cool.

I didn't even think to do that because the car was literally built in November 2020, but maybe there's a little bit of air in the system or the OEM fluid isn't sufficiently high temp Also does anyone have recommendations for a sort of light duty track pad? I used to run Pagid Blues on my Cayman (before progressing to Orange, which would squeal like a dump truck) but my knowledge is literally 10 years out of date now

Compare to ATE Typ200 @ 388/536 or Motul 600 @ 399/594, nevermind 660 or SRF . got off on a technicality posted:Also does anyone have recommendations for a sort of light duty track pad? I used to run Pagid Blues on my Cayman (before progressing to Orange, which would squeal like a dump truck) but my knowledge is literally 10 years out of date now IMO, ain't no such thing for a car that's seeing a buck fifty at the end of the straight. I like Pagid RSL19 "Yellow", but that is definitely not a pad you want to run all the time if you object to sounding like a dump truck. So you're better off swapping the pads for track weekends.

My car sticks out like a sore thumb on the road anyway so it's not like the huge SQUEEEEEEE noise it makes when coming to a stop makes much of a difference. Getting some proper heat through the brakes stops it but you never get that from road driving. I really need to pull my finger out and book a TD soon

Yikes. It really didn’t look that bad in the video. That’s a little scary. Also what was that GT-R doing in the middle of a spec Miata race? Is the track open to non-participants during those?

Ouch. Glad he's alright. I expected him to end up in the tire wall from the fracture pic, but I guess it was just a bad bump? Looking at it again it looks like he kinda squeezed the white car off, think maybe he was too caught up with that super fast Nissan passing and missed that the white car was so close to his quarter panel?

It's kinda not so fun when almost half the trackday turns up with full on race transporters, the day I crashed on was full of ex-Touring cars, Ferrari challenge, radicals etc and it wasn't very fun constantly having eyes on your mirrors. Part of the problem is that theres been a lack of actual race test days so some teams just sign up for a trackday and then pinky swear they won't do timing except they just ignore it and sit there with transponders and data logging. I did a day that included an entire grid of Caterham Academy cars because the series final was on the weekend after.

Yeah, when the wheel came around it grabbed his thumb and sucked it down to his stomach. Just bad timing since he was holding the wheel with one hand getting ready to go to 4th.

Took my 1LE out for a spin at waterford hills yesterday. Private trackday rental my buddy put together. I worked from the base track mode to sport 1, then sport 2 by end of day. I was hoping to get it to all nannies off mode in my last session but the day got cut short by another 1LE yeeting into the gravel at the end of the main straight. He is fine, car seems fine other than the extra 50lbs of gravel in its undertrays. Phenomenal weather, great vibes all round. I didnt time many laps but the best of my timed was apparently around a 1:17.25, which is around 3 seconds faster than the best I ever ran in my (stock power) BRZ. The camaro loving rules man. It was very appealing having a reliable daily that is out of box a stellar HPDE car. I just showed up half an hour before the track was hot, hopped in and had fun. I am still adjusting to this much power, Ive never driven a car this fast on track so the lower speed corner exits were very...fun. The car has a lot of rotation in it, but the nannies helped bail me out a couple times.

Rentals are pretty nice, no car prep to worry about or anything else. A friend runs SRG/Lindell Motorsports renting mostly SPec Racer Fords, Dads rented from his a few times and I'll probably try it later this year. When Dad did it he brought their RV and would hang out there between races then walk over, jump in the car and go. 1LE looks like it would be a lot of fun to beat on for a day.

Ran a halfday "test and tune" at Gingerman from 5-9pm yesterday. Drove there and back in the same day too, 3 hours each way. Totally worth it, gingerman is the best. Apologies for the high camera position, the GoPro was mounted too high on my helmet to see out of the front slit in my Session 1 https://www.youtube.com/watch?v=aWH_udQuPIo Session2 https://www.youtube.com/watch?v=7uwl0ZXxSGQ Bonus yeet, found the steering lock  https://www.youtube.com/watch?v=wHpY_1aHHCk

Why is it common for Miatas to run a less stiff rear sway in autox ? I know sometimes it’s for class, but I see it even in STR and beyond

Maybe they're trying to decrease oversteer?

I know sometimes it’s for class, but I see it even in STR and beyond I mean almost everything RWD runs a less stiff bar in the rear than front. The end that's producing less roll stiffness has more grip to use for other stuff.

Phone posted:droop travel Okay, so allowing a slower transfer of weight, to keep weight (traction?) on the inside rear. If there’s too little weight on the inside rear, when it re-gains traction does it sorta snap oversteer, like a motorcycle high-side? another question, for an entry level track day can you run coolant with antifreeze or do you need only water and wetter water or whatever additive?

No, but you can blow diffs up. I did it to my S2000 with stock power at WHP East. Antifreeze is fine, NASA AZ doesn't require it until W2W and PAS doesn't care about anything. e: honda whisperer posted:I've never seen a track day / hpde require you to ditch coolant. I'm guessing Virgil is coming over from motorcycles, our local org doesn't allow most coolants (unless something has changed in the last 5yr).

Virgil Vox posted:Okay, so allowing a slower transfer of weight, to keep weight (traction?) on the inside rear. So the swaybar just keeps increasing spring rate the greater the difference in height is side to side. It's effects don't linger when changing direction. If it's really stiff it can actually pick the inside tire up off the ground. See Hondas road racing. The inside rear touching back down won't cause something like a highside. I've never seen a track day / hpde require you to ditch coolant. Are you getting ready for a first track day?
