    Good to see you getting back out there Alex! I know the surface at autoclub speedway is terrible but you seem to be shifting pretty low in the rpm range. Form wise everything looked good. I thought you took a nice line through the course. Only thing i saw was coming in a bit to hot or just not braking early enough and over shooting the right hand corner coming off the hill. That's easy to do at autoclub speedway on that part of the lot where it's down hill and then it goes off camber.

    You should come to some events at el toro while they last. Grip is outstanding and the courses are wide open.

        thanks Jared, i was working on that corner all day, really having a hard time figure out how late i can brake and hard to brake for the 90 degree right-hander and ya its downhill and off camber.

        when you say the course at el toro while they last, are they going to stop having them there soon?

        thanks wh33lhop, that would have been great to pick up 3 seconds just from changing my shifting.
        one of the instructors there Geoff has an e30 and rode with me in the morning and asked me to try leaving it in 3rd for more of the course because he felt i was running out of revs in 2nd.

        I built up a 3.73 limited slip with 3 clutches

          El Toro is going to be turned into sub-divisions and a big park. It's sounds like the developers have finally got the ok to start demolition of the runways.

            You would have been at the top of second for some of it, but you were way out of powerband in third. 3 seconds was an exaggeration but you would have been much faster. Do you have a stock rev limiter or is it bumped?

            3 clutch LSD is fun, but I just got mine to slip driving up a mountain road. I'm thinking a ramp change or 4 clutch for the next diff.

              I agree, i could have left in second for more of the course and just used 3rd for the straight shoots,
              r3vlimiter has been raised and i made an led shift light to help prevent breaking a rocker arm.

                  Yeah tell me about it. Won't be suprised if it goes a lot slower than expected and or run out of funding. Fingers crossed we can keep running here for awhile longer.

                  Could your slipping problem be more of an issue with not having enough droop travel and too much roll stiffness in the rear. Iirc you're running around 750 lb springs in the rear in addition to a decent sized sway bar. Maybe try disconecting the rear bar?

                  Also it's my understanding that adding clutches to the lsd doesn't increase break away torque as much as it increases the division of labor.

                      It does both. That corner creates crazy load differentials on the rear so it's really hard on diffs. Only the MM diff in the 330 has been able to hold a lock around that thing, but that's with stock 330 suspension so a little different

                      There's enough droop but I've often thought about going to no or stock rear bar. Will test out next time I'm at an event.

                        I forgot my GoPro's memory card for the last autocross, but my friend got some decent video from outside the car. I beat my other DSP competitor (a new Civic Si) by 0.011 in this final run.

                          Changed class to STX and ran the Ventus R-S3 V2's for the first time. I used to run Nitto NT-01's and I would say that the V2's are *almost* as sticky. They are amazing 'street' tires.

                              Thanks. That was my first time in that class and on street tires, so I have some tinkering to do with the setup. A long time ago I pulled the stock rear sway bar, so I am going to plop that back in which should help a little with the oversteer.
                              I am also guilty of having a more aggressive than smooth driving style, which is not idea, but hey.

                                Very nice driving MisterMiniS!

                                Here's one from Saturday's practice. +1 i think.
