The video of me you posted was when I just joined H2R. I don't apex T3 anymore, I'm much better in T7 and T9 but still working on T8. Here's my fastest of 1:31.7xx at 3pm in 45 seconds into my vid here: http://youtu.be/i6nls5O2Unk Critique that one instead.

Lap Times Explained

Each column represents a vehicle driven on different racing lines. For example, the first row of the first column is the time for the Miata driven on its own line. The second row represents the Miata driven on the Porsche's racing line, and so on. It is expected that when a vehicle is driven on its own line (large font) the lap time will be the quickest. Otherwise, Al has not done his job very well.

The Racing Line at Harris Hill Raceway

Nestled in a nondescript section of Texas countryside lies Harris Hill Raceway. A short, narrow track with a pinwheel shape, Harris Hill provides the challenge of maximizing speed through connected corners with virtually zero curbing as a buffer between you and the weeds. Memberships are available for track day addicts, as well as affordable competitive options such as the H2R timetrial series.

Due in part to the fact that most drivers will not come as close to the boundaries as Al on a track without curbing, the optimal lap times are probably a couple seconds optimistic for this circuit. That said, there is a GT3 Cup driver that supposedly lays down 1'17s, so they're definitely not too far-fetched.

Turns 1 and 2 show the greatest variation in the racing line for the different vehicle types. The Miata, which usually takes the widest, most sweeping line, actually exits Turn 1 farthest to the left, and sets up for Turn 2 on the left edge. It's also the only vehicle to drive to the outside edge of the track between Turns 2 and 3. The motorcycle is the only vehicle that hits the apex at 3 - everyone else should stay wide.

Turn 4 is a decreasing radius right-hander, where you should pretty much stick to the inside the whole way around. There is usually a cone on the track at the exit, but it's too early to be used as an apex, so keep inside for a bit longer. Exiting 4, most drivers stay too far to the right in order to set up wide for Turn 5. Instead, get to mid-track in the straight section between 4 and 5, and turn in a bit earlier. The Miata stays out a bit wider and clips the apex, whereas the Motorcycle and GT3 RS should hug the inside all the way through.

Getting through Turn 6 with minimal or zero deceleration brings up Turn 7, where an inside line is the quickest no matter what the vehicle. Cars will then exit to the far left and set up a wide entry into 8 on the far right, as opposed to the Motorcycle, which exits 7 narrow and enters 8 narrow, too. Everyone exits 8 as fast as possible, letting the speed carry them out to the right side of the track.

At Turn 9, almost all drivers hug the inside for too long. The solution is to apex 9 very early and stay hard on the gas, letting the acceleration push your line out toward the left edge. Then, get the rest of the way left under braking before turning in for 10. The Miata can take 9 without lifting at all, even on street tires.

At Turn 10, most drivers take the Miata's line, but high power-weight vehicles should actually exit just a bit left of mid-track. This allows for higher speed in Turn 11 and through the front straight.

Chris Leclair - 2000 Miata

Founder's Notes

There are a lot of things about this line that could be quicker, and there's nothing wrong with that. Chris hits the apex at 3, which he shouldn't do in a Miata. He's also a bit wide coming into 7. Line through 8 is good, but it needs to be followed up with maximum possible speed through 9.

Chris Leclair Follow-Up 1'31.79

Founder's Notes

Chris requested that this video be included, with good reason! I'll keep the previous one as a demonstration of improvement. In this lap, I think that releasing the steering a little more coming out of Turn 2 - really running up against that left side if you're brave enough, will help carry more speed through Turn 3 and onto the straight. Other than that, the biggest thing I noticed was the transition from Turn 4 to Turn 5. It looks like the apex cone at Turn 4 is actually in the right place. Chris stays to the inside a little too long, and stays farther to the right than necessary before entering Turn 5. Nice lap overall!

Cayman R 1'22.9

Founder's Notes

This is the best lap I've found so far. This car is running a good 4 to 5 seconds faster than other videos of GT3 RSs and Vipers. Turn 9 is the biggest problem area - easily worth a few tenths!

Just Some Laps in a Fast Car

Founder's Notes

I'm not sure which of the several cars listed in the video title this one is. I'm having trouble finding quick laps from fast cars, so if you know any, please suggest them in the Additional Resources section. The line is OK overall, except at Turn 9, of course.

Anonymous 1000 Riding Hard

Founder's Notes

I have to assume this is a 1000cc. It's hella fast and the riding is good. Lap times are around 1'24. Being generous and assuming a reasonable optimal lap is more like 1'20, there are still 4 seconds being lost somewhere. I think most of it is on braking, and general inexactness in the line. Great riding nonetheless.

Founder's Notes

Similar to the previous video, but lap times are a bit slower.

Lars Cranks It Up

Founder's Notes

Lars kicked us another video with much quicker times, in the 1'21 - 1'22 range. Great hard riding!
