GSpeed's 2015 BRZ- SCCA Super Touring Build

So skimming over the hopefully obvious sarcasm... Are the pictures resizing properly? I had hoped if I left them big, people could blow them up if they wanted detail, but if it's making it harder to read, I can resize them.

Photos are perfect on my end. Great info!

[HolyAssertion]

Pictures are good.
I personally think it would be fun to come watch one of these sessions.

[GSpeed]

That'd be great! We usually test on Thursday and Friday mornings, though, rarely if ever on weekends. If you want to swing by, just let me know.

There are a lot of them, so sometimes when I load this page not all of them resize. 3110x2073 is a damn large photo though.

I like the "after driving" notes, great thread!

Finally got a video trimmed and uploaded! Here's our current fastest lap.

[Jonsey]

Very nice lap.


Our lines are very similar except for a couple of places. I take the same approach to rattlesnake but come back a little more center track to turn into the right slightly sooner to allow me to be farther right on the track when I turn into the left hander and can then apex it a little later and carry more speed down into wagon wheel. After Bryan's insistence, I stopped tracking all the way out on Buzzard's neck to be in a better position to enter Horseshoe from mid track, which allows me to carry a couple miles an hour more through there. I also short shift from 3rd to 4th between boothill and tombstone so I am not fighting to get the shift in on track out (same thing on Ricochet, short shift right before turn in). I shift in the same spots on the rattlesnake/wagonwheel section.

I'm really enjoying this thread.

Between the video and your notes. I have my homework Great tips. 1:36 is my best time. I'll take it for my first time ever on the track.

I would be cautious taking my notes over Dave's (the driver in the video) as he is one hell of a driver and has a lot more seat time on that track than I do (although I think a lot of that is in a very sweet viper). I am interested to see if the slight differences are a personal preference, if there is a good reason for doing them (which I could benefit from) or if he is still figuring everything out as the car is new to him.

thank you again for sharing all this information with us.
It is very valuable to see how and where the IR temp and shock system can be mounted.
Looking forward to see what these sensor are saying on the track !

Jonesy/Bramick, here's Dave's response:

"The comments Jonsey made are spot on. I have tried both of his suggested changes previously as they are the conventional wisdom of some. I found no improvement on the predictive lap time readout when doing so. Still, I am not convinced there is not something there. His comment on track positioning entering Rattlesnake is correct and very important.

On Rattlesnake: The fast guy with the most laps around MSR enters Rattlesnake very tight. Most instructors advocate a wide entry. Either way, Jonsey is correct, the place to focus on is being track-right before the left-hand entry to Rattlesnake. FWIW, my money is on the tight line - even though I try the wide entry occasionally.

On Buzzard's Neck/Wagon Wheel: I am convinced I am giving time up here but have not made the wider entry position work for me. I will keep at it though because I think this is my weakest point on the track. I will get Bryan [PST's Instructor] to ride with me and advise me. It is easy to get into a habit that is not the best thing to do (for example, tracking all the way out on Buzzard's Neck or driving cars around a race track for all, or part, of your adult life)."

As a medical device test engineer having to do this for a living (albeit a much more mundane version) I love nerding out on this crap! subd! Keep up the good work!

Had some slight rubbing in the front on the lower spring perch with the 245s on the +45 wheels, so we added some 5mm spacers. Didn't have enough thread engagement, so we installed some extended studs on the front axle. Rears will come later, just ran out of time.

Racecar!
