Lime Rock Park 2020- Flat Floor Test and Tire Explosion

[@MJ-mx2bp]

Thanks for sharing, love the real life ups and downs!!! And yes a 2014 tire miiiiight be a bit old. Time to add checking tire manufacture dates to the prep list!

[@SStirling070]

Great video. How did you like the MCS'? Any opinions yet?

[@ajhartmanaero]

JrMistMaker not yet. Way to many variables from last year and rain, etc. gotta wait till NJMP to get a better idea.

[@DBatty]

Would you be able to produce a video on how you use the AIM software for your data comparisons?

[@ajhartmanaero]

Davo Dinkum I have a few. Go to my videos page and search “aim” or “data” and a few should pop up.

[@DBatty]

AJ Hartman Aero whoops sorry. I’ll have a look cheers.

[@MustangIsKing]

Damn man you were at my hometown track and I missed it!

[@jonathontalley]

I’d say you got your monies worth out of them Toyos. Will love to see how much time you pickup from a set of hoosiers

[@diegofelipesanchezramirez5321]

What should be the price, for an entire undertray like yours?

[@chikogota]

hello, hope you dont take this wrong, but you dont keep a good record of tyre usage , from wear to heat cycle and as your friend said, ages aswell, fresh rubber being slick or street tyre is a must, for saffety and also for consistant to notice changes on suspension each slick or semi slick tyre has around 10 heat cycles before losing grip ( even if they arent too wear, you loose how the rubber behave, thats the unsprung mass of the load of the car) another thing, when you buy them new, the first cycle must be tu "bed in the tyre" trying to give a warm up laps and letting cool it is the best way, not to overheat the tyre and not to overwear on the outside, there are shops who bed them in from some bucks in the us hope to see you imrpove racing and take care!

[@ajhartmanaero]

Not taking it wrong at all since you are pretty much correct in a perfect world. But when real life hits and as a one man team don't have the time, or budget to do things to that level and buy new tires every weekend, you gotta make do. I've ran the Toyo RR's to over 30 heat cycles on several sets without issue, but the combo of the increased downforce, tire age, and punishment of Lime Rocks layout, it was to much. The tread on the failed tire looked good, but totally missed how old of a tire it was.

[@chikogota]

@@ajhartmanaero thank you for not taking it wrong, i am also a one man team and here where i live we dont have many resourses like in the US ( the machine for bed it tyres doesnt exist in my country) they dont sell slicks, only semi slicks with 80 treadwear and 180 treadwear ( the toyos you run they arent on the free market, need to import them) so i am not telling you to run new tyres every weekend, but to manage a new set on the season you are running (2020 rubber for example) and leave all the other oldones for testing/develping the car and even qualy. Also another thing it is that you need more practice/testing before and event, can you rent your local race track? here it cost around 30 dollars 1 hour and you need to be in one of the assosiations of the race track and to be a member you pay montly ( around 20 more) it is very important to have seat time with the amount of changes you like to do and have more confidence in your driving and car. Thank you very much for all the effort of recording and teaching to all of us ( you confirm alot of my theories) PS:i would like to talk to you much more, but i am not much of a youtuber

[@scottallen6970]

@AJ Hartman Aero. If you need any help in the Pits in the SCCA races up in the New England region, I can come over and help out anytime. Im in RI. Would loove to learn from ya. Plenty of track time here and track support.

[@ajhartmanaero]

Thanks. I don't run SCCA tho. I also make sure anything I ever need to do can be done by just me, but you are more than welcome to come hang out.

[@widfo_moto7345]

Why do you continue to stick with toyo's vs getting hoho's?

[@ajhartmanaero]

Chris Davis primarily money. I had to run Toyos in Ai so just burning through them before getting Hoosiers.

[@widfo_moto7345]

@@ajhartmanaero ah ok. Time to toss them all in the garbage and make the switch!

[@Charper]

Is there any benefit to running the solo2 with the MXG vs running the AiM GPS module with the mxg?

[@ajhartmanaero]

Charper732 the aim gps wasn’t working and with everything going on, I didn’t have time to figure it out so just tossed the SOLO back in.

[@DomesticAlex]

Great video!

[@noncog1]

Are you not allowed irs swap?

[@ajhartmanaero]

noncog1 sort of. Wait for our next videos.

[@p0intdk]

Down on power since the Corvettes are running away from you?

[@ajhartmanaero]

DragonDragon yeah. By about 60 or so.

[@p0intdk]

@@ajhartmanaero need some bigger turbski´s

[@ajhartmanaero]

@@p0intdk nah. just a tune can get me there. I'm "de-tuned" to be legal for American iron still. Never re tuned it for ST2 power.

[@sarahdell4042]

AJ Hartman Aero Assuming you can easily load another tune? 60+hp would be nice I’m sure ha

[@MarkIsOnFire]

I came here for the spins in wet qualifiying, and I was let down...

[@ajhartmanaero]

Me too. I shut my camera off when we were waiting down pit lane and forgot to turn it back on.

[@MarkIsOnFire]

@@ajhartmanaero poo.

[@ajhartmanaero]

Mark Petronis seriously. It was right after the spin I thought “ well that will be cool on video... oh crap, my camera isn’t on!”
