Karen K's 2006 ESP WRX build thread, sponsored by IAG Performance
Okay, okay, I should have done this when I started. The car was created from D-stock scratch after Subaru pulled the SCCA Solo contingency monies, and I've been running it in close-to-full ESP trim since. It's similar to, but different than, Greg McCance's car (mccanixx), which is a bug-eye, and Greg, Joel Fehrman (AUTOwrXER, '05 BSP STi) and Billy Brooks (bbimpreza at MODE Racing) have all helped me with setup.
If a moderator thinks this would be better in the Project Cars thread (since Greg's build thread is already there), please move it. IAG Performance has helped a ton with this car, from the installation of all the goodies, to the fixing of those goodies when they decided to go bad. There is a summary of all the parts currently on the car on their site. Also, Vorshlag Motorsports accepted me into their Test Pilot program for 2009, as I was one of the first with a GD chassis car to install the AST 5200 strut setup on my car, but I switched to the ZZYZX/Koni coilovers in 2011 when a set magically became available. I was accepted into Mishimoto's sponsorship program this year, after my car served as a test-fit mule for one of their FMIC kits being developed. Kartboy and TurnInConcepts have also been very generous with their help as well. After five years of running the car in ESP, an ESPL National Championship, and what seemed like constant changes to the setup, the car was just reclassed to ASP. As far as I'm concerned, the car is outclassed there, because it's in the same class and the same line as the STi. If I am going to run ASP, I would just start with an STi rather than converting this car to a pseudo-STi. So, it's for sale, and I'm done with autocross for the foreseeable future.

Couple of questions... Why no front bar? And why no moAr rear spring rate?
More importantly, how do you like the 5200's? Ive been eyeing the 5200's (known as XIDAs in the Miata world) for quite a while now. |

Joel (or an engineer) could explain the "why" better than I can. It has to do with the spring rates I'm running. Quote:
The most difficult thing about the 5200s was choosing the spring rates (again, I'm not an engineer, and there isn't really a "set" setup for the WRX -- only me, Greg McCance and Drew Little seem to be seriously running these cars at the National level in ESP, with Christian Nissen bringing his up this year too). The only other issue was figuring out where to mount the nitrogen canisters. When I finally decide on a strut tower bar, I think there's going to have to be some... ah, "rearrangement" under my hood.

Im assuming youre on R's then? The reason I asked, I never got a good chance to compare between bar and no bar with my WRX before it was sold, but on street tires, the bar was considerably better, especially on turn in.
Either way, just watching the videos, that car is a beast. The driver isnt bad either. Since you had Koni DAs (as do I), would you say the 5200s are better/worse/about the same? I had mine revalved, and to be honest, with just a few events in the car under my belt, I already feel like Im leaving performance on the table. |

I'm on R compounds, yes (A6s, to be exact), but it shouldn't matter that much. Good (ST) street tires are going to be pretty close to an R comp.

Nice intro Karen. It'll be interesting to watch the development between your car and the other ESP cars duking it out nationally. I really like the way my FSP car handles with no bar(s) as well. (imho) It's all in the springs, ride height and alignment.....get them right and you don't need the extra roll stiffness.

What's the advantage of the 02/03 front axles/stubs? Are they stronger? (Sorry, I'm not as familiar with differences in years as I should be)

This build thread is waaayyyy better than ^^^^^^^ you know who's ^^^^^ thread.
Are you running the 295's for gearing? Everything I hear is the 285's are just as wide, but shorter. Also find it very interesting that with that much tire we still have more roll stiffness in Justin's 06 STi STU car. John |

Thats because you and Justin are crazy! But more that the trained eye can catch the loop hole in this!
Nice write up so far Karen. |

The spring rates were chosen to give a slightly higher rear suspension frequency than the front frequency. When you consider how much lower the rear cornerweights are than the front, you can see how you end up with a higher rear suspension frequency than the front despite the difference in spring rate. |

Do you have any bushings at all? The difference is pretty substantial not only from a feel and consistency perspective, but a reduced delay between pressing the gas and the time that the car moves. I would also suggest pnp-ing everything you can get your hands on: exhaust manifolds, intake manifold, TGV deletes, TB, etc. Of course it all depends on how much you want to spend (as even pnp-ing has the cost of gaskets). I had a buddy with a nearly stock 05 WRX drive my ESP 06 WRX and he was most impressed with how quickly power came on, and how much it had. |

Steering bushings are a nice upgrade as well as steering feels much sharper. Quote:
http://forums.nasioc.com/forums/show....php?t=1942411 After doing all the PnP I could (including gasket matching the heads) I get full spool (21psi) at 2800 - 3000 rpms in 2nd gear depending on what rpm the engine is at when I get on the gas. |

ESP vs STU
How do you feel you're doing in ESP compared to others in STU? Do you think the WRX is competitive there against the camaros and others?

Now, against the new Mustangs -- especially the 2011 model -- I don't know if anything currently in ESP will be competitive against those. Quote:

The bushings have been on the table since the beginning of the build. The main problem has just been the time to install them. It's something that I will need to revisit. I've got NEDivisionals and the DC ProSolo coming up in the next month, and I need to get some other issues worked out first. Last weekend was the first event I've done since Nationals, and so getting the rust out of my system is also a problem. Karen |

Let me pose this question - do you think this car, once you tweak it to your liking, will be competitive with the new mustang gt (current model and next model with more power) in esp? I heard rumor that Sam was going to prep his mustang for ESP, and that made me decided to give up on ESP. But then I heard he is going to buy the next one with more power and use that instead. I drove Christian's at the Finger Lakes Tour last year, and it has a far better powerband than my ej20. So I wasn't going to do another engine swap just to get beat by the new mustangs. However, if we can get the 08+ same lined in the rule book....
Ok, I'm just rambling now. So the question remains - do you think the current bread of 2.5L ESP WRX can dominate good driver in a new Mustang GT that's prepped for ESP? Jim Perrin (who is contemplating going back to street mod since Mark Daddio isn't there any more) |

Came home early to grab the WRX to run it over to IAG Performance for a wheel bearing check after the codriver noticed excessive play in the front passenger wheel during the swap back to streets on Sunday.
Found this in the mailbox : Traffic was bad enough in Baltimore this evening that I didn't get to IAG early enough that the bearing could be fixed, but James installed the shifter. I did talk to JJ about the bushings too. I should have them before the DC Pro, if not before NEDivs. Karen |

The only counterpoint you'd have is: Will it be as fast as a BSP corvette? If that ends up being the case move it or put 02-09 wrx on the line. Of course I don't think you'd see that the first year even if it was. Why do that? On paper? Yikes! |
