"On the road, the P25 is simply better, faster, stronger everywhere.... P25 is as easy to drive as the standard car. It's firm, but doesn't jar and soaks up the bumps better than a stock MY06"
- Dean Evans - Motor Magazine Mar '06.

"Performance is really good compared to a standard STi..... compared with a standard car its much more user friendly and driveable."
- Rick Bates testing P25 against stock MY05 STi

And its a lot faster too! Rick Bates, (prominent Australian race and test driver) tested P25 at Wakefield Park recently and we compared the performance against a similar test of a stock 05 STi conducted by Motor Magazine earlier in the year. In both cases Rick was the driver and detailed data logs were compared for both sessions.

Highlights

P-25 does a best lap time of 1:07.75 (optional tyres) compared with a standard MY05 STi best time of 1:10.12.
On stock tyres (Potenza), P25 laps in 1:07.82.
Maximum sustainable lateral G's of 1.0 for P25 up from 0.92 for stock STi.
P25 acheived peak lateral G of 1.24 vs 1.16 or stock STi
Rick Bates says "Compared with a standard car its much more user friendly and driveable."

Based on the STi Subaru Impreza, Whiteline have released an upgrade that is set to make a real impact, not only on the Subaru performance scene but also higher value cars such as Porsche, BMW and such.

In partnership with performance specialists MRT, this car offers the complete package. We wanted to make something that was true to our cause, that is to create something that is reliable and comfortable midweek, whilst still being extremely potent for the weekend.

Similar to the Litchfield 'Type 25' produced in the UK which is based on the more costly (and higher spec) "Type C" Japanese limited model, this has many similar products to the P-25, such as EcuTeK reflashed factory ECU, Whiteline enhanced suspension, body kit improvements and more, but what we wanted was to offer a locally produced model that is actually better. Our aim is to produce a package that is far superior to the factory delivered models, in both reliability, power and torque whilst providing Porsche beating performance. By all accounts, the P-25 has achieved just that.

Performance Specifications:
In excess of 300Kw of Power and 500Nm of Torque at the flywheel. Factory standard is 195/6000 kW and 343/4000 Nm. (see dyno graph)

Suspension Modifications:
    Adjustable Struts front and rear.
    Front sway bar
