Could it be anything to do with this: (I doubt it) 
Fitted with four-piston fixed Brembo brake calipers and meaty 13-inch front brake rotors, the STi possesses braking capability far beyond what normal drivers would ever ask for. Crabtree and Dabb's on-track incursions, however, asked for Brembo's Gran Turismo front brake kit. The rear of this STi retains the factory two-piston fixed caliper Brembo setup. Featuring stronger and lighter four-piston calipers, braided stainless-steel brake lines, two-piece brake rotors and Brembo brake pads, the Gran Turismo kit has proved its worth at many of Southern California's local tracks. With super sticky 245/40/17 Hoosier road racing slicks mounted on stock lightweight forged 17-inch STi BBS wheels, this Subaru can stop and turn with the best.
By now, you must be clutching this magazine, pondering and scheming how is it exactly that a Subaru needs this suspension, these tires, these brakes - and how it makes more than 700hp. The key is the fully built engine, dubbed the R5 by Crawford Performance of Oceanside, California. One of the premiere Subaru engine builders, with years of experience in the rally and sandrail world, Crawford started the recipe with a boost-friendly 2.5L engine block. The block was machined to accept replaceable wet sleeves, forged CP pistons hung on a 84mm Crawford stroker crankshaft, 4340 forged Pauter connecting rods and was then finished off with piston oil squirters. The final displacement for the R5 engine is a massive (for a four-cylinder Subaru) 2.8L.
Still using stock STi cylinder heads with no porting work, the R5 engine was given a Crawford Performance air/oil separator kit and TGV deletes before facing boost. Crawford Performance's own CP35R turbo kit was fitted to the R5 engine to handle pressurized power duties. Based around a Garrett GT35R turbocharger, the kit makes use of a Crawford Performance up-pipe, downpipe, Tial external 44mm wastegate and 3-inch exhaust system. The CP35R kit also includes all the necessary piping to connect the GT35R blower to a massive stealth black APS front-mount intercooler that swallows up all the available space in the front bumper.
Ingesting more boosted air than Satan himself could have deemed possible, this STi pushes the limits of power with lots of fuel. A Walbro 255lph in-tank fuel pump forces huge amounts of gas to the Crawford Performance billet fuel rails before it's shot out of 720cc/min fuel injectors. Tuned with a MoTeC M600 engine management system by I-Speed USA, 710hp and 742lb-ft. of torque at the flywheel was realized on I-Speed USA's Dynapack dyno.
