Jeff, i managed a 1:45.4 at practice last week however that was a) with a few clean laps and b) RE55's
I have the GPS/Driftbox data, so if you have same we could compare.
I havent tried the stocker bridgestones, and the be frank i dont think i could manage a 1:46.x with them really, so i think you're doing well with a 1:46.8 (easily better than i ). FWIW, i could only manage about 235km/hr on the straight, i think the gearing of the 18" track wheels doesnt help for such a long straight. On another note, the highest speed i was doing through turn one was about 170km/hr. I havent done many laps of EC, i need to grow some balls for turn one - that is hurting my times big time.
I think there should be a mid-1:44 in it with fresh 55's and some clear track, perhaps better. I just need to grow some gonads for turn one. We had a supersprint on Sunday and the best i could manage was a 1:46.7. I had 5 sessions all day (15 laps, 3 hot laps per session) and for most of the laps i was held up. For those two or three clean laps, i just didnt make them count. I just couldnt match the time from practice. Maybe next time
Anyway the car held up good and tranny temps seemed quite manageable within the supersprint format.
I also swapped out my pads for some Carbotech XP12'and to be frank, i don't think it was worth it. The brakes felf spongy and just less progressive than the stocker pads. But that's another story.
