Unfortunately, the subject hasn't come up while I was talking to r-comp guys, so I'm not sure if they work well for you guys.
After a 2 day on the 5.0's I was happy enough with them. Driving the car without ABS made me realize I was likely over slowing with the HP+ because they had so much initial bite. I can still get ABS to activate now that it's fixed on the 5.0, but you need to MEAN it and with 3-5 chances at a corner you figure out pretty quick how much is needed. Data still shows over 1G of braking force on asphalt, it's just easier to modulate.

The dust was still there, but less than HP+ after a 2 day. I could barely see the outline of where the numbers were on the car with the 5.0 while the HP+ would have been very noticeable.

Nice, I'm glad to see they have improved. Since they are nice enough to give winners store credit.

Default AutoX in the rain setup?

Last weekend I had my first experience with autoxing in the rain (3rd event ever). I ran into situations where the car would push exiting tighter corners. I know that could probably be fixed by not coming in so hot, but I was curious what you guys change in either your setup or driving style to deal with the wet.

forutne 500 coils
25mm fsb - sti 20mm rsb
-3f / -1.5r
225/45/17 RS3's 36/34psi dry but ran 32psi square in the wet
Also have the option of running 245/40 Z2's

Too much front roll stiffness is your problem.

I set my center diff to RWD and drive with my right foot in the rain.

And run hoosier rains.

Wish I had 6spd lol. This weekend is looking like another rainy event so I guess I'll try unbolting one of my endlinks and compare notes.

Unbolt both. The bar moves enough with one side connected that the unconnected side can hit stuff.

Yeah, that's not going to help things... those tires in the rain, over-driving entry, and a stiff front setup.

At 28 seconds was that a pointer cone with no regular cone or was that a downed cone from a previous run? Ya coulda stopped and got a free rerun.

I'm not sure how different the forresters are, but I like my GC with matched swaybars front and rear. I'm running 22mm adjustible front and rear. with 330 lb/" front and 300 lb/" rear springs. I'd like to run smaller swaybars, but I'm compensating for springs that aren't stiff enough.

What spring rates are you running?

Also remember that the car, even setup properly, is slower to respond in the wet. You need to make your inputs earlier, especially steering. Once you get some rotation you can use your power to get the car moving in the right direction.

Of note, this changes significantly once you slap some Hoosier wets on

Hey all, just thought I'd drop in and ask an aero question. This is pertaining to the front splitter on my 07 sti. The rules are somewhat vague to me so I figured i'd see what others thought, here's the section in question.

Quote:
L. Front splitters are allowed and shall be installed parallel to the ground (within 3 fore to aft) and may extend a maximum of 6.0” (152.4 mm) from the front bodywork as viewed from above. Splitters may not extend rearward past the centerline of the front wheels. No portion of the splitter may extend beyond the widest part of the front bodywork as viewed from above. Aerodynamically functional vertical members, such as splitter fences or endplates, are not allowed.
They describe it as 6 inches from the front bodywork. It's my contention that the V-limited lip that came stock on my car is infact part of the front bodywork.

Here's another section to support my argument.

Quote:
H. Front hoods (engine covers), engine covers, trunk lids and hatches not containing glass, front fenders, rear fenders not part of chassis structure (unibody), front & rear bodywork, and side skirts may be modified or replaced and may be attached with removable fasteners. Associated hardware including latches, hinges, window washer system, and hood liners may be modified, removed, or replaced. Non-metallic fender liners may be modified, replaced, or removed.
So what does everyone think? I'm thinking I can be 6 inches from my v-limited lip, especially since its saying I can also modify or replace my front bumper, If I was so inclined I could put a voltex front bumper on and take the measurement from that, I believe that would give me even more forward protrusion than a V-limited lip on a stock bumper.

Thoughts?

I'm interested in what Tim has to say but... yeah, 6" from the bodywork could be interpreted as 6" from the stock splitter. I don't see a requirement that you can't run the stock splitter *and* the one that's 6" out from it but I also don't see that you can remove the stock splitter but use it as the point off of which you're measuring. i.e. you can have double splitters where one is "super-long" but you can't have just the super-long one.

6" from the bodywork, so aftermarket bumpers count and the OE v-limited stuff would also count. Personal opinion and all.

Splitters fall off for efficiency around 6" though so I never felt the need to build mine past 5.75". And you hit more cones the longer you make it.

Thanks for the feedback guys! Glad to hear you are both thinking of it along the same lines as myself.

Currently trying the girodisc S/S brake pads. Got 1 event in the rain on them and they seem to work pretty well. A bit less bite than the HP+, but you can easily get the ABS on on the dry with them. I'll report back on noise and dust once I have a bit more time on them.

First event with the DCCD Pro controller under the rain. Started with the knob 50% and gradually reduced it to around 3/8 of a turn. Worked pretty good, but I wasn't able to get a small drift then full lock behavior to help turn the car in corners. Event was on a karting track so a few corner where very slipery probably because of rubber on the inside of turn. Any people with DCCD Pro? What setting do you use on the rain? I was using an old set of re71r with little thread left on that day. Here is a video: https://www.youtube.com/watch?v=pNtoZohb8VA

I vary the setting based on how the car is doing. Most of the time I leave it alone though. Just auto and slight understeer bias.

First off, another teaser for the Canadian Nationnal Championship coming July 29-30-31 in Montreal. It would be nice to have a few drivers from USA at the event. here is the link for the inscription: http://www.cac2016.ca/index.php/en/8...istration-info

The site (PMG Technology) is one of the best for autocross I've seen. 700m x 400m of laser level tarmac with no obstacles. Surface is only 2 years old. Best run of the day on yesterday event which was food for FTD and first overall PAX: https://www.youtube.com/watch?v=lcgoKB2yPqs

Question on car behavior. My car bounce a lot when I get early on throttle. Here are a bouch of videos that show:
https://www.youtube.com/watch?v=sv5HhvaIFNc
@31s
@55s

https://www.youtube.com/watch?v=lcgoKB2yPqs
25s
28s (off throttle)
52s
62s
67s

https://www.youtube.com/watch?v=BsIiMXNNHm4
24s
31s

Anybody with had these behavior in the past and found a way to solve it? Car has 360whp / 370wtq. Suspension is fortune auto, 12k front, 10k rear. I can post the dyno shocks if some suspect this could be it. I also have a carbonetic rear diff and DCCD Pro to control center diff. DCCD was setup in auto mod with adjustment knob at 50% setting.

How much are you lifting the inside rear and how fresh is the rear diff?

The inside wheel lift probably 2 inches in worst situation and the rear diff has 4-5 years of autocrossing on it at least on my car. I bought it from Subydude, so not sure of the history on it. Could it be the rear diff?
