The Hank Watts guide is a pretty good school line, although a bad line through turn 3.

They will be repaving Thunderhill this August, which will create a whole-new fast-line...

Stay tuned...

Good point on school lines. True in T2 also, and many other places. In T3 it's off camber and gathers a lot of marbles and debris in the outer third. Best to keep the car on the inner third at entry and wind into the very late apex there.

Just as a general note for the Miata and other momentum cars, the fastest line takes an earlier apex, but we don't like to teach that as it results in a lot more wrecks and offs.

Cheers,
Craig Northcutt

thats sound advice concerning the inner third on the offcamber t3. ive tried taking the more traditional line and have found myself fighting for grip.

NASA teaches that the exit of turn 2 is to the far-right side of the track. Follow the far right side of the track through turn 3, apexing against the berm about 2/3 through it. Turn in early for turn 4, since NASA always runs the bypass (lame).

The inside of turn 3 is less off-camber and smoother than the outside-to-inside of the turn. At least until August when they repave the entire track...

I cant see the video...but I have a lot of days at Thunderhill. The miata line thru T3 is on that inner side..other cars start about 3/4 the way out..and then pinch it in by that apex cone. I have never spun on T3..but I have many other places. Most groups teach that the exit of T2 is that berm on the right.

Last time at T-hill we ran it reverse (Llihrednuht or "Litt'l red nut"). Due to a significant incedent, we ran over the "eagle's nest" in reverse. That was outstanding...

If you're interested in running reverse, NASA has an event coming up Oct 4 & 5. With the fresh pavement and new berms, it should be one helluva good time.

If you're new and looking for an instructor, feel free to hit me up.

The new track is MUCH faster.

The miata line for t3 enters really wide, and comes back in near the apex.

I had one before but ended up sold it, but my friend just got one and we are about to start having fun with it :)

s2k is almost ready, but don't expect getting any podium with 200hp car in modified class, just for fun.

Thanks for posting this and thanks to everyone else for the other tips. I have never even been to the track and we (my work) will be building and racing a Porsche 928 @ T-Hill for The 24 Hours of Lemons. Hopefully we get to drive the track before we actually race.

I'm a big fan of this track too. Heh the stories I could tell, I've spent a lot of time at the hill. My favorite section is the downhill entry into turn 10... late-braking madness! Or going into turn 1 flat out riding the edge of lift-off oversteer. Hardest section for me is the final two corners. The fast line into 14 is so easily blocked that subconsciously I always run the defensive inside-line. Gotta get over that to get faster.

Glad this was resurrected, I'm driving T-Hill for the first time with NCRC on 4/1! :D

When you think of T3 think of your weight. Where is your weight as you start your turn.

God I miss TH, haven't been there since before it was re-paved. T3 was a good place to watch the common rookie mistake of lift oversteer. Got to have a light touch on the gas though with the off camber outside-to-mid width of the track. Was that improved much?

I love the way skiing translates to driving. I always love using the terrain making turns, pre-jumping knolls and pressing the backs. You want to have your braking done before the car unweights over a hill or rise, then apply throttle (press the back) just after cresting to keep the car settled.
