I know its already been noted on here, but I just finished the most amazing race I have run in any of the 4 gt's. I used the BMW M3 GTR, stock hp, with all drivetrain, brakes, and suspension upgrades and R1 tires to do the Laguna Seca Enduro. I went out on the R1's, hung tough with the Shelby Series 1 and the Saleen S7 for 11 laps. I had the driving aids off and coming through the corkscrew, I completely punted it. 14 seconds behind, I just pull into the pits to put some R3's on this bad boy. I come out about 45 seconds down and think, this will be fun. The Shelby pits on lap 16, I think, ok, he's got 5 stops. I stop at lap 21, ok, 10 laps on R3's, I'll have 8 stops. Uh-oh, that's 1:30 I have to make up on the Shelby, and what, the Saleen is pitting on lap 22, thank goodness its not 23, or he could do it on 3 stops. Anyway, I battle on. Lap 80, the Shelby and I pit together, I am 4 seconds back. We come out together and have it out. But the R3's are just too much, I take it easy on the last lap and finish 8 seconds up. Whee! On lap 40 or so I was really thinking that the spin would cost me this 200 point beauty. Anyway, took 2:19:53 to finish the 90 laps, 8 second margin of victory, fastest lap in the very low 1:28's I think. Anyway, with 8 * 30 seconds for pits, that leaves a 1:30.6 average lap. This should give people some idea of pace if you want to try other cars. I tried the Suzuki GSX-R/4 on S2's, went 27 laps before the rears gave out. I was running with the leaders after they pitted each time. I think maybe with S1's in the back you could easily make 30 laps for a 2 stop race, or maybe even 45 for only one stop. But the Suzuki is definitely winnable for 200 points (I even think I added some HP upgrades). Cheers and thanks for this wonderful thread.
