Comprehensive Evo STU prep thread?
Toe settings?
Not sure if it's cool to post this question in this thread, but I figured I can get the right answer here:
Davemac mentioned the toe settings should be zero or should be set depending on an individual's driving style. My turn is always a little abrupt and late which always cause understeer. Other than improve driving, should I set the toe out a little to improve turning?
On the separate note, I went to Boeing yesterday and did a "Walk-in" registration and saw all the good drivers run. (Corey, Adam, etc.) The STU Evo's are definitely the faster cars out there and the whole STU class is extremely competitive. But somehow the Mini S's (GS) stole the show...

I typically like a little toe out for initial turn-in. I typically turn in at a slow but rapid pace (if that makes any sense) and seems to me that the toe out is beneficial to my style. I think most Evo's run toe out along with a ton of camber as these cars love both
The other thing is tires and the pressures. They play a huge role in the handling characteristics of the car.
The biggest thing though is the driver
Which Evo were you running? STU or AS?

The course at Boeing was very, VERY tight but, kind of expected that coming from a course designer that drives an Elise!! Overall though he did what he could with the space. The trick to that course was definately taking the 180s slow than coming out with the throttle burried.
I know I left sometime out there in the slower sections but, thats racing. This year is very, very competitive in STU. A few real fast guys have switched over and a few more a running the full season plus a couple other guys are finally getting their cars dialed in. STU for sure has to be one of if not the most competitive class in the Philly region.
I am still working on my new KWs trying to get them dialed in, which is always a nightmare until they are setup.
Are you running Warminster this weekend? If you need any pointers don't hesitate to ask, I would be more than willing to ride along and even do an instructor run if needed.

Jake and I were toying with the idea...
I've been wanting to run DC but, always miss registration. I'll try to sign up for the 12th is my schedule it open that weekend
Thanks! I will definitely take you up on the ride along offer.
I have signed up to the Cumberland autox event this Sunday. (I live in Maryland, and it's 2 hours to Cumberland or 2 hours to Boeing) I will definitely show up for the next Boeing event and stop by and say hello. I think Davemac is coming to Fedex on the 12th and the remaining sign up spots are available on Sunday at 8pm. Mike N and the M3's rule the STU DC region and I think a STU Evo assult from Philly will make the STU class here in DC more exciting. Thanks Again. Danny

Can we keep this thread topic to STU preparation. It started off good and has some decent information, but now it looks like it's evolving into a 'show and tell' for local regions discussion.

No offense, really, just thought we would all benefit if we stayed closer to discussions related in preparation, testing, STU legal parts, etc.
Of-topic's here and there certainly doesn't kill it as long as it comes back to the main topic.
This is one of the few threads I do enjoy.

Leaps from the tallest building in Omaha ...
Yeah ... but I had already purchased Ohlins R&T when you guys were still in the design and testing phase, yes I have waited "that" long ... I just tend to prefer the Ohlins dampers for personal nit-picky reasons. I'm sure your design is right up there with Vishnu's, Mueller's and Robi's, on top of that the "local" support would have definately helped tremendously.

In an effort to further develop this thread a bit we've established a lot of very good base points to start building an Evo for STU. Let's take another step.
Let's get some opinions on rear ride height relative to the front. There are two schools of thought here and different reasons for each.
1. Add Rake (rear higher than the front). The general consensus of the "School of Rake" is all about weight transfer. Keep the front lower to keep more grip up front.
2. Drop the rear. This is a technique used by Mitsubishi in the last iteration of the Evo IX.V. Along with the titanium alloy turbo impeller to drop spool time the rear suspension gained some attention from the engineers to help the last generation Evo chassis go out with a bang. The theory behind the 5mm rear drop was to reduce the unloading and lift of the rear suspension in tighter turns. Mitsubishi's engineers explained that this aids in getting the power down on corner exit.
I understand that, at this point, this is a very simplistic view of the drop or rake theories. Please add to the STU discussion any data that you think will help. Answer this way, 1. Drop or Rake 2. Back it up bish!
Chad, have you got any input from your LMP days and testing you've doe for various tire and car companies?
