No conjecture, no commentary, no love it / hate it. Nothing but factual information. I will delete any drek.

I'll start things off with the spec sheet from SoA Media Center.

April 2006 Press Release

SUBARU UNLEASHES IMPREZA<sup>®</sup> WRX<sup>®</sup> STI<sup>®</sup> LIMITED FOR 2007
<!--[if !supportLists]-->·<!--[endif]-->Less Show, Same Go
<!--[if !supportLists]-->·<!--[endif]-->Leather Interior, Power Moonroof
<!--[if !supportLists]-->·<!--[endif]-->Only 800 Numbered Units Available
NEW YORK, <st1:date month="4" day="13" year="2006" w:st="on">April 13, 2006</st1:date> Subaru of America, Inc. today unveiled the 2007 Impreza WRX STI Limited model at the New York International Auto Show. The new edition of the road-conquering Impreza WRX STI packages creates greater comfort and refinement with subtler exterior styling, but does not sacrifice the performance of this street legend.

The WRX STI Limited will be available in the fall in a limited run of 800 numbered units, 400 in Satin White Pearl and 400 in Urban Gray Metallic.

The 2007 WRX STI Limited delivers all the power and performance of the standard model. This new limited-edition version adds a layer of refinement and design detail enhancements targeted at a new group of driving enthusiasts looking for supercar performance but with an understated demeanor. Designed by Subaru Tecnica International (STI), the high-performance and motorsports subsidiary of Fuji Heavy Industries Ltd., the WRX STI Limited is descended from the Subaru WRC Rally car.

The WRX STI redefined the performance car category when it was introduced in 2004. We know some enthusiasts have resisted the temptation to buy one simply because they want more everyday driving comfort and refinement, along with less aggressive styling, said Fred Ad****, executive vice president, Subaru of America. Now, with the STIs reputation for pure performance unquestioned, we recognized an opportunity to broaden the cars appeal.

Less Show, Same Go
The 2007 WRX STI Limited stands apart from the standard model with an appearance thats more low-key, and even stealthy. A new trunk-mounted lip spoiler replaces the standard models large dual-plane rear spoiler, and the black

--more--
aluminum roof vane spoiler is deleted. A new, deep front lip spoiler further distinguishes the WRX STI Limited from the standard model.

New Enkei wheels with high-luster paint replace the BBS<sup>®</sup> wheels, keeping the same 17 x 8-in. size and 225/45 ZR17 Bridgestone Potenza RE070 directional performance tires. Behind the new wheels, black Brembo<sup>®</sup> brake calipers with white lettering have a more reserved appearance than the gold and red-painted calipers on the standard WRX STI.

All WRX STI Limited models feature distinctive black gloss B-pillar paint and high luster paint for the exterior mirrors, and this special edition model includes standard fog lights.

New Refined Interior Keeps the Focus on Performance
The interior of the 2007 Impreza WRX STI Limited balances the performance-directed design and attitude with a dose of refinement. Most notably, the WRX STI Limited replaces the perforated blue high-grip Alcantara<sup>®</sup> fabric seating surfaces with leather and new dark gray metallic bezels and interior trim.

For the first time in a WRX STI, the performance-design front seats are heated for all-season comfort. Also enhancing all-season driving pleasure, the 2007 WRX STI Limited features the first-ever power glass moonroof on this model. Beyond the changed interior appearance, additional features include new carpeting with improved sound insulation materials, an auto-dimming compass rear view mirror and an audio system input jack for an iPod or other digital music player. Finally, each car in this series gets a sequential number plate.

The standard automatic climate control system integrates cabin air filtration. SIRIUS Satellite radio availability enhances the versatility of the standard 120-watt AM/FM premium stereo, which includes a 6-disc in-dash CD changer and six speakers.

Rally Tested and Road Ready
All Impreza WRX STI models are powered by a turbocharged and intercooled 2.5-liter DOHC Boxer engine producing 293 horsepower at 6,000 rpm and 290 lb.-ft. of peak torque at 4,400 rpm. The Subaru Active Valve Control System (AVCS) variable valve timing technology helps provide strong torque characteristics throughout the engines operating range. A manually operated water spray feature helps to bolster intercooler efficiency during spirited driving.

All WRX STI models are exclusively equipped with a 6-speed manual transmission that features carbon-plated double-cone synchronizers on 4th, 5th and 6th gears to help ensure durability.

Driver Controlled Center Differential (DCCD) <st1:street w:st="on">All-Wheel Drive<
From its launch, the WRX STI has been equipped with one of the most advanced and most performance-directed <st1:street w:st="on"><st1:address w:st="on">All-Wheel Drive</st1:address></st1:street> systems on the market, regardless of vehicle segment. The Driver Control</st1>:place> Differential (DCCD)
--more--
<st1:street w:st="on"><st1:address w:st="on">Symmetrical All-Wheel Drive</st1:address></st1:street> system uses a planetary-type center differential to provide a 41:59 torque split, with automatic and manual differential modes.

Center differential lock-up is controlled by both a mechanical limited-slip type differential and an electronically controlled limited-slip differential. The mechanical limited-slip differential activates and operates initially in response to changes in engine torque, improving overall vehicle stability when accelerating or decelerating. In automatic mode, the electronic limited-slip differential controls the differential lock-up by evaluating the amount of lock-up in the mechanical limited-slip. The total amount of lock-up is based on the combination of both differentials. A steering sensor input improves torque transfer response by more accurately relaying the cars cornering situation.

Set in automatic mode, the DCCD system can vary the torque distribution ratio as needed in response to vehicle acceleration, deceleration, steering angle, cornering force and wheel slippage.

In manual mode, DCCD allows the driver to select center differential lock-up to optimize <st1:street w:st="on"><st1:address w:st="on">All-Wheel Drive</st1:address></st1:street> performance for varying driving conditions. The driver first selects manual mode with a console-mounted button and then turns a thumbwheel on the center console to select from among six levels of lock-up. Increasing the locking factor keeps more power at the front wheels (max. 50:50 torque split with 100 percent lock-up selected), which the driver might want in certain driving conditions or on particular road surfaces.

A helical-type limited-slip front differential and Torsen<sup>®</sup> limited-slip rear differential help to optimize power distribution side-to-side, helping to prevent the inside wheels from slipping during cornering.

Competition-Bred Chassis
A super-stiff Ring Frame Reinforced body structure with a hydroformed front subframe provides the foundation for the high-integrity Impreza platform. Compared to the standard WRX models, the WRX STI models are lowered by 0.4-inch to help lower the center of gravity.

The 4-wheel independent suspension inherits its inverted-strut technology from the Impreza WRC competition car. Aluminum front suspension lower control arms and aluminum rear suspension lateral links reduce unsprung vehicle weight. A quick-ratio steering system yields 2.6 turns lock-to-lock, and the steering rack uses a cannon mount for greater rigidity that improves on-center response.

The powerful Brembo Performance Brake System employs front discs measuring 12.7 inches in diameter and 1.2-inch thick and utilizing 4-piston, fixed-position calipers. The rear discs are 12.3 inches in diameter and 0.8-inch thick and use 2-piston, fixed-position calipers.
--more--
A combination of Electronic Brake-force Distribution (EBD) and the Super Sport Anti-lock Braking System (ABS) helps to reduce stopping distances and understeer compared to conventional ABS systems. EBD provides precise control of braking pressure between the front and rear wheels based on the vehicle load to improve stability and stopping distances. Super Sport ABS, using input from a lateral-g sensor, can control the braking forces at each rear wheel independently, optimizing the braking ability during hard cornering to help reduce understeer.

All Impreza, WRX and WRX STI models are equipped as standard with the Subaru Advanced Frontal Air bag system and front seat head/chest side impact air bags (SRS). The drivers side air bag deploys according to the drivers proximity to the steering wheel, as measured by a sensor on the seat track. In the passenger side front seat, a sensor module detects weight on the passenger seat first determining if its occupied, and if so by a child or adult to control air bag deployment.

I posted this on Nasioc:

Here listed are the mph at 7,000 RPM's on the 2007 STi's.

For all of you drag racers out there, look at 4th gear




1st / 2nd / 3rd / 4th / 5th / 6th


35.4 / 57.6 / 84.6 / 113.2 / 132.5 / 170.2


And for those who will be able to trap at speed 114+, the shift to 5th will be less of a drop than before... Much better gearing in almost everyway.

can anyone confirm if the limited will also be offered in canada? i have seen nothing on the website as of early this week... odd that some dealers are already seeing delivery and there is noting available here yet... i suppose they could be imported the same
No-go on Canada. 800 only to the USA.
Have to import them..............;)

Edmunds.com has posted info about the '07 Impreza trims including the non-limited and limited STI. It still needs some work though. For instance 2 blatant errors I saw with http://www.edmunds.com/new/2007/subaru/impreza/100796920/colors.html are it only shows SWP and WRB as the exterior colors and "Anthracite Black cloth, leather" for the non-limited STI :eek:rly: http://www.edmunds.com/new/2007/subaru/impreza/100796920/options.html
shows SWP, OBP, UGM, CGM and WRB fog lamp trim covers which seems plausible for the exterior.

new type injector clips ( gold) top feed injectors, older ones were side feeds . new bigger wastgate port on turbo, much safer/ smarter/ faster ECU,
new gear ratios that enable you to go to 114 mph in 4th ( important for the drag racers)

this can all be checked with doug over at topspeed

Here is the list I got from my dealer (I talked to several and this is the only guy who knew of any changes, they are one of the better Chicago dealers):

-Base Price is up $500
-Gear ratios have changed for improved in town drivability (see above)
-Helical type TORSEN limited slip rear differential (as noted earlier)
-Rear center armrest with trunk pass-thru
-Secondary exhaust emissions air pump that complies with LEV2 emissions ratings
-Revised cylinder head design for improved cooling
-110 amp alternator

Hope that helps

This is incorrect. I took a magnet to the lower arm as well as the front sway. The magnet sticks to the sway but not the Lower arm. The lower arm end is also machined.

I'm particularly interested in the tranny changes since my 06 hits the rev limiter in 4th coming out of T4 at MAM, which is an ugly place to hit it and will get uglier when I'm using sticky tires that'll let me carry more speed into the turn.

Does anyone have a list of the ratios in the 06 or their 7k-rpm speeds so I can analyze the two boxes side-by-side and further convince myself the tranny is enough reason to trade in? :)
