ESP - The competition

[BeBop86]

I'm curious... would anyone protest a JDM hood scoop on an 02 WRX?

I know the rules say body pieces must remain stock as a whole... and the 06/07 won't fit the bugeye... but the opening dimentions are basically the same size.

Locally? No, probably not unless you were winning. Nationally? Maybe, but especially if you were winning.

[UWMechEngr]

Yeah, I wouldn't risk it for any national tour races, or the national championships

I would like to have one, I think they look great on a bugeye. But, I don't. Stuff like this, however benign, is just bad ju ju for any class. IMO at a local it sends a bad message, at a national event it sends a bad message and you're just bait.

I didnt think you were allowed to run that at nationals but its so minor I wasnt gonna protest you for it.
My understanding of the rules is that you shouldnt be allowed to run it

On another note, Porting question for ESP,

port intake/exhaust no further than 1" from port/manifold interface

The intake/Exhaust openings on the heads can only be ported within an inch though?
Also in ESP the throttle Body cannot be touched at all from my understanding? No porting of that?

For a Lower brace, Am I allowed to run the Type 1 Cusco bar that only attaches in 2 places? I know the H Brace is not Legal at all

Are aluminum control arms a legal swap? I would like to be able to run larger sway bars on my 04 WRX wagon but they only make them so big for the wagon. If theres a way to legally swap to Sedan sways i would like to do that.
Thanks guys!

[Hold_Fast]

In regard to front sways on a wagon, certain manufacturers will fit both sedan and wagon. I have a perrin 25mm on mine, fits with no issues.

Aluminum control arms off the 06-07 wrx TR are legal, since they are on the same line. The aluminum control arms off an STi are not legal.

[sureshot007]

I had Whiteline 29mm adjustable bars on my wagon. The endlinks are different between wagon and sedan. I don't remember if the bars are the same, but they sent me sedan endlinks by accident, and they were never going to fit.

From the current rules for SP:

Carburetors, fuel injection, and intake manifolds are unrestricted
subject to Section 15.10.D.

15.10.D states:

Traction and/or stability control systems, as defined in Section 12.12,
must be standard parts at standard settings or electronically disabled.

12.12 states:

A system that adjusts engine power, braking force, or torque distribution
when wheelspin, understeer, or oversteer is detected or predicted. Conventional
limited slip differentials (e.g., viscous, passive clutch, helical/
worm gear, locker) are explicitly excluded, but "active" differentials and
their controllers are included.

So you can PnP anything above the engine so long as it doesn't affect your traction control or differentials. 0_o

I don't think bracing of any kind is allowed, except non-triangulating strut tower bars... IIRC

[mygreenbird007]

Anyone here going to Dixie? Could use the company. My husband and I are currently the lone WRX entries in a sea of Mustangs.

Thats what I like to hear, I checked with the person that classes the majority of the cars for our area and this was his reply (I responded in Italics) ;

The numbers are not continuous so I would have to read this in the context of the section it came from. However, just my own recollections you are not allowed to port your intake in SP. I believe you can use any one that came on that model engine but I do not think you can port it. That is considered messing with the internals and that's not allowed until SM.

T. Intake and exhaust ports and manifold openings may be matched provided no change is made more than one inch from the port/mani- fold interface. Material may be removed to facilitate port matching, but no material may be added.

And that includes the throttle body. My under standing of that was the ports into and or of the engine block,/head

No, I would disagree. It only includes the point where the intake/exhaust manifold contacts the head intake/exhaust. So only 1" either way from the point, basically where the gasket would be on either manifold. The throttle body is too far from that point.

I thought if it was an underbrace that connects withing 2" of 2 Suspension points its ok but no underbracing that connects 2 Body points from side to side on the vehicle.

Also new question...
3mm Phenolic Spacers Intake -> Manifold.. Legal or not?

Think of intake/s this way. From the air filter to turbo inlet is open. Free to do whatever you want.

From the turbo charge outlet to the head you are free to do whatever you want. (make your own intake, make your own throttle body, hell go to individual throttle bodies, make your own intercooler.) About the only rule in there is maintaining a BypassCompressorValve that functions as stock.

The spacers are legal. But, just buy plastic tgv's instead. Having had both they don't raise the intake and are more effective.

I'm pretty sure you're right on cross bracing. Can only connect to two points.

On the heads. Everything you want to port for more flow is below the 1" rule. You are basically just port matching the tgv's at that point. Which isn't necessarily bad. Just not ZOMGWTFBBQ I just found 12HP!!!!!!



edit: Your guy is right and wrong. He is correct in the porting of the interface of the intake and heads is legal. Wrong on everything else, because everything else (regarding the intake) is open.

[UWMechEngr]

Strut brace rules:

C. Strut bars (per Section 12) are permitted with all types of suspensions, subject to the following constraints:
1. A 2-point strut bar may be added, removed, modified, or substituted, but only with another two-point strut bar.
2. A triangulated (3-point) strut bar may be removed, modified, or substituted; substitution may be with either a triangulated or a 2-point strut bar. The connection to the chassis (i.e., firewall, bulkhead) must be in the standard location.
3. Lower suspension braces must be attached to the lower suspension pickup point locations on the chassis within two inches (2”, 50.8 mm) in any direction of the actual suspension attachment to the chassis.
4. Except for standard parts, no connections to other components
are permitted.

Subframe Connectors

E. Longitudinal (fore-aft) subframe connectors (SFCs) are permitted with the following restrictions:
1. They must only connect previously unconnected boxed frame rails on unibody vehicles.
2. Each SFC must attach at no more than three points on the unibody (e.g., front, rear, and one point in between such as a seat mount brace or rocker box brace).
3. SFCs must be bolted or welded, but welding must be to the OE subframe stampings, not to the fl oor pan in between.
4. No cutting of OE subframes or fl oorpan stampings is permitted. Drilling is permitted for mounting bolts only.
5. No cross-car/lateral/triangulated connections directly between the driver’s side and passenger’s side SFCs are permitted. Connections to OE components such as tunnel braces or closure panels via bolts are allowed and count as the third point of attachment. No alteration to the OE components is permitted.
6. SFCs may not be used to attach other components (including but not limited to torque arm front mounts or driveshaft loops) and may serve no other purpose.

Thank you, I finally got an email back from CACC autoslalom director as well and was basically told this.
Gaskets and phenolic spacers are ordered, Now I just need to find some Larger 06 WRX injectors and let the modding begin!

[Crawlerado]

Yeah he's wrong on the intake manifold porting. The 1" rule is going into the heads and honestly there's no point. I'm making 230/265 on a untouched 2.0.

When I went to the Farmington Prolo I had to remove my H brace and my STI rear lower diffuser. Everything else was legit. Greg and I went over each others cars pretty heavily since we were the ONLY Subaru guys there.

Tire question!


I've got Hoosier A6's for my dry / semi dry tires... and can't afford a set of Hoosier wets.

What's a good daily driver / wet tire?

I'm leaning more towards Continental DW vs the Dunlop Z2's, as I heard the DWs are better than the Z2s in the wet (which would be their primary use).


Thoughts?

For where you are I'd probably do the DW's, even though you can't go wrong with either for rain. If I wanted a set that did double duty street/rain I may opt for the Dunlops. They're probably more fun for the occasional spirited street driving.

[BeBop86]

That's true, and kinda what I was thinking. I've heard nothing but praise from those running Conti's during the BC slush series.

Alrighty... ABW flares ordered (picture), and 18x11's ordered. So excited, hopefully the flares are somewhat wide enough (only adding about 30mm extra width, but on the plus side when compairing to Karltons, less flare = less weight ). Might need to do some widening on the front fender well opening.


Question:
I'm looking at bumping up to 315's this year, but was curious if anyone had any input on Hoosier A6 vs the BFGoodrich R1 S? Only info I can find is that they run wider than Hoosiers. Anything noteworthy?

[Hold_Fast]

Those flares look good. I just picked up some Karlton flares (for mah wagon), and am still trying to decide on wheels. Mind if I ask what wheels you went with?

The flares:

[BeBop86]

Originally Posted by Hold_Fast

XXR 531 18x11 +20 5x100/5x114.3

5 lbs heavier than my a Wicked Awesomes (24 lbs vs 19 lbs) but I'll be putting at least an inch wider tread down... Hopefully that will be okay. All others that size were $$$$ this way I can buy two sets.

[subydude]

I weighed my set of 531 18x11 +20's at 26.5 lbs. Maybe my scale is different, but the combo of tire/wheel was almost 55 lbs.

Also, you guys are going to have problems with body seams and inbound clearance with 315's.

[BeBop86]

Hammer time?

I think that's a one way ticket to SM since there isn't provision in SP for "massaging" inbound bits for clearance.

I can say without hammering on my car I wouldn't have been able to go lock to lock OR able to lower it much at all from full ride height. And you have to cut a LOT of front fender to get it to work. The rear is also an issue, but that's another story

[UWMechEngr]

*looks at Nationals results from last year* I think you want the purple crack.

I don't think so... I've been chatting with someone else on here that has this same tire and wheel setup and the only issues they had was front fender well openings.
