Hello. My name is Dan, and today I doomsday prepped
-
auto-x cherry popped. way too much fun. my non-sticky tires were slow, but oh-so-fun. joe was better than me considering i only beat him by 0.25 sec and he's got the m42.
dopplegangers.
for kaiserolls. lots of turbo miatas there rippin it up.

Congrats on the (Street Modified) 1st place! No need to tell anyone it was just you and I haha, if we had similar tires you would've smoked me for sure. You also get the award for longest 11's leaving the start line.
You car looked awesome as usual, can't wait to go do it again!
-
What tires are you guys on?
-
Also glad you enjoyed it. Most people are hooked after their first event. Some just need some convincing to give it a try!

nexen nfera nogrips. only tires in 225/45r16 that weren't $600/set when i was looking. i might sell my e34 summer wheels to fund some better rubber for next year

nogrips lol
I've got Firestone Firehawk Indy 500's (Bridgestone Potenza RE003 in the rest of the world). I would be lying if I said I didn't go home and immediately look up 200 treadwear tires that would fit my car
-
If you guys get some 15s, tire choices are soooooo much better than 16s. Cheaper too. I run the Re71r in a 205/50/15. It's pretty amazing. Brooke runs the hankook rs4 in a 225/45/15. They are also good.

id be lying if i wasnt looking for cheap 15" wheels right now...

Convince me to sell mine so I can justify cutting my car up and running 15x10s
-
i really need an external mic for the back of the car so you can hear her sing. watching the video makes me see where I could have made up a lot of time by looking a turn ahead, or not hugging cones in unnecessary places. also i typed in 2016 for some reason, lol.

another day, another 2/32" of tire gone.
Madison Sports Car Club setup a great course. It was more high speed than my first event, which was a fun change of pace.
I remembered to setup my front camber to MAX and air up the tires to 45lbs, and it certainly made a difference.
I met a couple of cool guys out there. A couple of other BMWs. I got to do a ride along in Sam's m3. Man, it feels fast from the passenger seat! I learned that I would love to have better brakes. The m3 brakes haul that thing down so much faster than the e30.
Vince's m3.

Wait, did you say 45 psi?????
-
If they are softer sidewall all-ish seasons maybe I can see that actually.
CARRY ON DAN
Glad you're having fun with this!!
-
love those photos! I do wonder if the lack of droop on a low coilover setup is a hinderance to grip compared to a spring and damper combo that stays in contact with the road. I would think so but lots of fast racecars lift the front wheel so who am I to judge?!?
~45 psi is what some of my friends ran for autocross when I would spectate many many years ago

I guess it depends on the tire/suspension setup.

Going up in psi seems contradictory to what i've been taught and what i've read. If it works it works but did you see what it's jumping up to with heat?

Tires rolling over too much maybe?
-
Typically you do bump them up for autox. Short runs with tight turns that cause tire rollover and variations in heat. The magic tire pressures vary by car, suspension, tire, driver, road surface, weather, etc. Variation in pressures from front to rear depending on all the above. Plus you'll see folks with tire blankets and water sprayers trying to get the right heat - grip combinations.
Chalking the tire shoulders and seeing the wear lines is one easy way to check for rollover and whether you need to adjust pressures up/down. Pyrometers are a step up for measuring heat variation at centers and edges.
All sorts of ways to go deep down the rabbit hole with this stuff. At this stage though more fun to just bump up the pressures, go fast and try not to kill too many cones.
