    Thanks for the advice about the straps...will do.

    I've largely learned to ignore the "normal" noises in my car at this point. My clunks come from the RMM personally....I also have buzzing sounds from things vibrating from the built motor, and a mysterious, really fuckin loud squeak that comes from the front driver's side area and seems to follow the motion of the shock at "intermediate" temperatures. Never have traced it. The shock actually broke at one point on that side and was replaced. Now different camber plates. Same sound. I believe it may be the springs rubbing against the spring adjusters. I did sand down (by that I mean angle grind) the springs at one point to make them fit some helper springs and spring dividers. It also could be my catch can which is in the same area and ghetto mounted to the frame. But when I wiggle it by hand (or anything on that side), I can't get anything to make the sound! And if the car is cold or hot, it goes away. Guess I should just alternate between driving like a grandma and an asshole. Oh wait, that's what I already do.

    Today was a bad day at the Evo school sadly. First off the car was pissing me off because it just doesn't have enough rear grip now and it's super tail happy. I checked my alignment sheet and there's -1.4 deg DS, -0.8 PS...that's not nearly enough to keep up with the front at this point, so hopefully I'll be able to take it back to the alignment shop next few days and get that addressed.

    The real kicker is, 2nd gear popout is a serious issue now. It was kind of a problem before, now, even with no shift weight, and no knob, it pops out under heavy braking in bumpy sections. Realistically, I know it's the trans, but it sucks because I know the synchro and fork pads are still good since the gear engages perfectly under all conditions. But @phate tells me on his trans, he had popout because the dog teeth were worn. I'll look into fitting a temporary solution (hairband or something to keep it in gear), but I'm probably going to have to end up replacing the whole 2nd gear set and synchros. That is going to suck...I have never attempted anything so technical before. Oh, and to top it off, I found the pivot shaft seal is also leaking. FML.

    At least the K04 and the XS Power seemed to hold up great. The car ran perfectly all day, barely knocked at all even on 93 with crazy BATs. Multiple instructors thought my car had an "insane" amount of power. I started tuning it on E85 on the way home after picking some up, and I am finding E35 isn't enough octane so far, so I will bump it up to E40 or so and hen post results after that. I'm also having trouble maintaining traction in 4th with E85, so getting a clean log is difficult.

    With E85, so far it seems 24 psi is available consistently at 2500 in 4th. ;)

    So happy that people are using those vorshlag plates!

    Regarding 2nd gear popout, if you still have a shift weight and/or heavy shift knob, take it off.
