yep. Advan AD08 255's on all four corners. I absolutely LOVE them! I mounted them (on a different set of wheels) for the first time just before DGRR and I got to test them out on the Dragon. I was thoroughly impressed. The grip was unbelievable, but the best part is they are easy to drive at the limit. They let you know when you are getting too close and dont just let go on you.
Also, to update the thread a little...
This year's DGRR was a trial run to shake down the car before any track days. It was the first time I had a chance to really push the car since the winter build. The motor performed flawlessly, however I had not done much as far as engine related modifications. Just some tweaking to my maps.
The drive down gave me alot of time to test out PFC boost control. I got rid of my Greddy Profec B Spec-II and used the solenoid along with the PowerFC to control boost. I have the OEM fog light switch wired up as a Hi / Low boost switch. I love this, because I dont want my interior filled with excess gauges and gadgets. Anyway, I found that the PFC does a better job at controlling creep than the Profec did, however I got slightly better response with the Profec. I am currently am getting creep in the taller gears because I am trying to limit the boost to 10 psi and with the amount of air that my ported engine flows even the ported wastegate cannot keep up. Its fine though as I have tuned for the creep and I will be upgrading to a three bar map sensor in a week or two and turning up the boost.
On the roads leading up to the Dragon and the Dragon itself I got a chance to really test out the tires suspension and brakes. As I mentioned earlier, I was very impressed with the tires. However, what was just as impressive were the brakes. The stopping power was incredible and the modulation night and day improvement over my old Hawk HP+. The Hawks felt like I only had two pressures, on or off. These Endless ME22 Competition Pads really responded well to pedal input and I could really feel the threshold approaching and control it well.
On my first run of the Dragon I was on the brakes VERY hard the entire time and on the second to last turn I felt the pedal stiffen up and I started to loose bite. I parked the car at the turnaround spot (without ebrake applied) and let the car cool down. It appears that I overheated the rotors. I removed the pads when I got home and took pictures to send to the Endless tech. They informed me that there was no sign of the pad being overheated so it must have been the rotor. The dragon is particularly hard on brakes because you are hard on the brakes non-stop turn after turn without much cooling time between braking zones. Also it is relatively low speeds so my brake ducts would not have been providing much cooling unlike in a track environment when the car sees 90-100MPH between braking zones. In addition to the rotors overheating the first turn on the run back i found that the fluid had boiled while sitting and I had to pump them to bring the brakes back. I have since installed Ti backing plates to reduce the heat transfer through the pads to the pistons while sitting in the paddock. I also have some plans to provide some additional airflow to the brake ducts which i will post once I start working on it.
and another shameless picture of the car, because I love my new wheels so much
