terror rising's street/auto-x build
I adjusted the preload all the way down and it didn't have much effect on my WGDC values. I'm now hitting ~24-25 cutout closed with 85% WGDC. I haven't logged it open but I'm guessing it's going to hit ~27-28. I looked at my clutch pedal assembly and it seems to be the spring that is sticking slightly and messing with my pedal height. My new suspension will be here on Wednesday and I need to figure out if I'm going to try to install it and align it before my next event (Sunday) or if I'm just going to leave it alone and do it all before the event after that in three weeks.
Sorry for the lack of updates. The AST coilovers are installed and it's been rough aligned by myself. It drives great and with the extra caster from the Vorschlag plates my car really doesn't care what the road's doing anymore, it just goes where it's pointed. The caster from the LCA bushing made the steering feel heavy, this additional caster from the plate feels great. I'm waiting on a new 3-port to arrive to keep working to diagnose why I can't get full boost. I won my class at an auto-x a couple of weeks ago and hope to do the same this weekend.
I'm really looking forward to this weekend's event so I can feel these in action. As of now they're sitting around -2.75 F / -1.25 R. I tweaked them to match side-to-side but that's just sort of where they were when I installed them. I figure I'll see how I like it before adjusting it any further.
Had a good day at auto-x winning my class. That's actually a joke as it was only me and a WRX that was pretty much stock. I got a crappy pull of first heat (course sweeper) but still made the most of the day. I only got four runs so not really enough to do any testing on the rebound settings. Car was not as tail happy as I wanted it to be so I'll adjust the rear bar before next race as well as try to play with the settings. I've pretty much decided I'm going to take a course at a local track so I can get some time on a track to play with suspension as well as improve my driving skills. My new Grimmspeed 3-port will be here tomorrow and hopefully that's the reason I'm not fully boosting.
Vids definitely look like you are pushing a bit and not much rotation. With that setup I ran rear Hotchkiss bar at full stiff and front whiteline 26mm at either full soft or me with the cusco bracket. I also had a fair amount more front camber too, running -3.5deg on street tires and -4.2 on race tires.
I also don't know how much the ACD is helping compared to a viscous center on the Evo, my DSM days are really a good comparison cause the floppy chassis made swaybar weight transfer basically a single ended tool.

The car definitely wasn't rotating on entry like it was before. The corner exit understeer has definitely improved I just need to focus on improving turn in. I don't have Cusco brackets up front so I'm stuck with the only hole in the 26mm Whiteline bar. I didn't mess with my rear sway as I wanted to see how it performed on med-soft before changing anything. Perhaps I'll start on med-hard next event. I still wish I had a bit more power oversteer but since I'm down on power due to boost issues I'm not going to worry about it for now.
Turn in can definitely be helped with less front rebound and a bit of static toe out. That wont fix steady state or exit, but will work on entry. Do you have the rear diff rebuilt?
Well the new boost controller seems to be holding better (65% WGDC gets me ~20psi instead of 14-15) but my 3-month old PC680 crapped the bed on me at the start of tuning. I was out of town for work last week so I couldn't address it. I brought it to the store I bought it from last weekend and today they told me they're giving me a one time warranty on it. I can get my money back or get a new battery (not a PC680) but whatever I buy won't have a warranty. Stopped at Advance Auto after and I can get a Deka EXT-14 for $103 or an EXT-30L for $145. I'm torn whether to just replace the 680 with the -14 or to buy the 30L and fab a new tray. I need to make up my mind pretty quickly as I have a race on Sunday and need to retune my WGDC settings before then.
