The cam is an Aiptek HD1080p. I opened it up and soldered in a mic jack (see pic ~ on top) from Radio Shack so that I can use the built in mic or plug in an external mic. I am using a $20 Radio Shack lapel mic which I ran to the trunk. This way, I get the exhaust/engine sound and do not get any wind noise no matter how fast I am going. I also added a Sunpack wide angle attachment. The pic attached is the mount. It is a Panavise suction cup mount, which I added a brace to prevent the camera from shacking back and forth since it is a "vertical" camera and even with a solid mount on the bottom, the top (lens) would vibrate back and forth over bumps. This weekend will be the first test with the new modification to the mount but street test show a big improvement. I am running 600lb/500lb springs and the car is pretty stiff.
I loved the Goodyear F1GS3s on the street, absolutely HATED them on the track. The sidewall is so soft, that the car would yaw and then set and grip. It made the car feel sloppy. You don't notice this nearly as much on the street even when driving hard.... goes to show you how much more demanding driving on the track is of the car.
My next set of street tires wil be the new Khumo XS. If you are running 16/17 get these. If you are running a 17 front, then maybe the Dunlop Z1 Star Spec or Bridgestone RE11s.
As far as pads.... I really reccommend getting a set of track pads. I have farted around with combo street/track pads and while they are great for autoxross, they just don't cut it at the track. This weekend will be the first weekend with Carbotech XP10/8s. Another good option is Cobalt Friction's pads ~ although about $80 more a set.
People say stock pads are fine on the track for a novice, etc. Maybe the first time if you are not super agressive. However, I can get the stock pads to fade in about 3-4 laps and I have a lot of cooling ducts. I also see novices braking too much, which will contribute to fade more so than an advanced driver who is on/off the brakes and not braking as much before turn in.
If you don't mind swapping pads - go right to a track pad don't dick around with combo pads like the Hawk HP+. It only takes me about 1/2 hr to swap out all the pads the day before. They are fine to drive to/from the track ~ don't let someone else tell you otherwise (disclamer ~ unless it's 30F out). But don't daily drive with them on all the time.
Tires - stick with a Exteme Summer tire. Trust me, you don't need to be running Hoosiers or R comp. In fact, when I finish off my Nittos I am going back to a street tire. Dealing with 235s on the front is just a PITA ~ I have to raise my car to keep from rubbing on bumps and then lower it back when I put my 16/17s back on. If someone makes a 215 R comp, then I would switch back to the R comp. Nitto NT01s or Toyo R888s will at least let you drive to/from the track when it's raining. If you are running Hoosiers or bald NT01s then you better pull over and wait it out.
