For those of you running NASA TT, I've got a couple of quick and semi-embarrassing questions after reading the TT rules book. There really needs to be a "getting started with TT" webpage or something.



-For my first weekend, how does this work with the check ride and TT license? Do I basically need to do the Friday test-and-tune and have the check ride then? Or am I going to be allowed out with the first session (practice) with one of the guys in the right seat?

-I don't understand how gridding works. I get that the first session of the weekend is considered practice and none of those times will count for the event. But does my fastest time in that first practice session determine where I grid up for the rest of the weekend?

-I also don't understand how impound and/or the end of a session works. The way the rule book reads, it seems like the end of a session means everyone goes to "impound" and you can't do anything to the car. You have to either sit in the car and wait, or stand beside it and keep the hood closed. You're then released back to the pits? This whole section of the rules was very confusing.

-What is a TT log book? What am I writing in it? Is this something I have to hand in or keep in the car at all times as proof of something?

-My car looks to be borderline for TT3. When I use the online calculator, and ballpark it with what I know the manufacturer curb weight is plus my own, plus the fact I have tires with UTQG of over 100, it looks like I can just barely squeeze into TT3. I'm still not sure that I'm doing this correctly, however. If I have to run TT2, I'm going to be at the far end of it and will get absolutely crushed.

-Where do I register my transponder? I've already set it up on the MyLaps app.

-For a car with a severely raked hood and front bumper, where do you put the number and class decals? If I put them on the hood it feels like, they're almost unreadable.

Reach out to Chase Johnston on FB to arrange your check ride. It's best if you can knock it out Friday, but I suspect they'd let you run in TT warm up session based on your experience.

Gridding on the warm up session is on the honor system. I usually grid up 5th to 10th depending on who's there. The idea is to let the faster guys grid before you.

That time however will be used to set your grid position for the first timed session so yo want to get a clean lap in the warm up session with decent tires. After that, your fastest time of any session sets your time for grid all weekend. Most people will set their fastest time of the weekend in 1st or 2nd timed session of the weekend. Grid is for the most part established without too much change after 3rd session. Some regions like NOLA make you use the previous session to set grid for the following session, so if you miss a session you may start at back. Texas uses whatever time in any session is your fastest.

Impound is basically a National thing. For Texas, there will be someone at the track exit that will tell you whether or not you have to go to the scales (aka impound). If you are selected, you will get weighed and tires will be measured/checked if you're traking any type of tire modifier.

TT log book costs you $20. You buy it a tech and it allows you to do tech once for the entire year versus having to do it each event. Only thing that is written in mine is the tech inspector's signature. It's good for any region. Bring $20 to tech and get a log book and annual inspection sticker. I keep it in the truck but try to use it when I do HPDE's to avoid going to a tech shop.

You should always run in the highest class that you can. Have you posted your class forms and dyno sheets to the online compliance database? I can look at and offer you advice. You will want to get to running Hoosiers eventually, so plan on detuning or add weight to make it work for TT3.

You need to enter your transponder# in your NASAPRORACING.COM profile. Look at entry list for TT/Racing and you will see a column for TX #'s. You can also do it when you register, but its better to do it now.

Don't worry if front numbers are not readable. Every corvette faces same issue as you. Main thing is the sides and the rear.

Hope that helps. You can e-mail me at Denis dot Clavette at Comcast dot net with any questions.

in that picture i posted, there were no studs holding the pad on the backing plate. when they got this low, there was some significant vibration through the pedal. i'm not sure what from, but the pads communicated to me and they were all pretty thin. no chunking at all. i did cook my fluid though.

Haven't gotten the dyno sheets or compliance forms done yet, that should be set on Tuesday after I take it to G Speed.

Can you explain your comment about running the highest class possible? I'm not exactly doing this to win tons of free tires (right now), but I don't want to be severely outclassed and be frustrated. TT2 has some scary-fast stuff in it...looking at the track records, they'll absolutely obliterate me.

I meant it opposite of how it came across. Higher # being slower class. If you can fit in TT3, then try to make it work.

Man - that must've been scary. Sub'd to hear what Andie says.

Love me some Cobalt Friction! He has always taken tons of time to explain his process and recommendations so I trust him more than most.

Cool, thanks. I'm looking at the schedule for the weekend and not sure I understand the TT run groups. Do all TTers go out at once? e.g. if I'm TT3, am I out on track with TT1, 2, 4, 5, and 6 at the same time?

Yes. We all go out in the same session at the same approximate time. This is why grid position is so important. If you grid at the back and are having to pass a bunch of miatas, you're going to ruin your time and theirs as well. Again, it's usually all sorted out in the first couple of sessions. You'll usually get 2 clean laps at a short track like MSRC. Make them count!!!

Possibly. If I want to run a Hoosier, the detune would be very minor. I could also do a small ballast box.


Other alternative is to take the BTM aero mod factor but that would be a hassle to remove some of that stuff -- and might impact lap times at a higher speed track like COTA where I need the downforce.

How are your corner weights? Ballast path if you have issues getting a good balance and ballast helps. Otherwise, detune, maximizing what’s allowed (not sure if it’s peak or area under curve that they look at).
