Subaru WRX vs STI - 3 Reasons Why The WRX Is Better

Should I buy the WRX or the STI? Is 2015 Subaru WRX STI better than the standard WRX? The 2015 STI features a 2.5L boxer four producing 305 HP while the 2015 WRX has a more modern 2.0L producing 268 HP and peak torque at a low 2,000 RPM. The WRX is also lighter and achieves better fuel economy, all the while almost identically as fast as the STI. The STI offers additional limited slip diffs, a driver controlled center differential, larger brakes, tighter steering, and a more rigid chassis. Which is best?

Anti-Squat Suspension Geometry - Explained

Anti-squat suspensions are used to reduce body squat by altering the rear suspension so that the forces resulting from accelerating pass through the control arms and suspension linkage rather than through the coilovers or struts. This is typically done with vehicles with high power to weight ratios. By reducing body squat, the rear wheel geometry will remain more consistent, and the vehicle can maintain a specific ride height which can be beneficial for aerodynamic purposes as well as driver control.

I Drive Godzilla!! 2016 Nissan GT-R NISMO

The 2016 Nissan GT-R NISMO features a 600 HP 3.8L twin-turbo V6, enhanced aerodynamics, and a N├╝rburgring developed suspension.  The hand built engine features dual overhead cams, 4 valves per cylinder, plasma sprayed cylinder bores, 9:1 compression ratio, and aluminum block and heads. The engine produces 600 horsepower @ 6,800 RPM, and 481 lb-ft @3200 RPM, with a maximum engine speed of 7000 RPM. This is 55 horsepower and 18 lb-ft over a standard GT-R, thanks in part to large diameter high-flow turbocharges which are also used in GT3 competition. 


MSRP As Tested: $165,780

The base GT-R Nismo starts at about $150,000, while the MSRP of the car I’m currently testing rings in at $165,780, primarily due to a nearly $13,000 weight-reducing titanium exhaust.

The engine torque passes through a 6-speed dual clutch transmission, which can preselect the next highest or next lowest gear for incredibly quick gearshifts. From there it can send up to 100% of the torque to the rear wheels, or as much as 50% to the front wheels depending on speed, lateral acceleration, steering angle, tire slip, surface conditions, and yaw rate. 

As far as aerodynamics are concerned, the Nismo’s front bumper, engine undercover, and rear spoiler increase downforce, 220 lbs more than the standard GT-R while traveling at 185 mph. The center of pressure is managed well from front to rear to optimize handling, and yet the vehicle maintains the same drag coefficient, 0.26, as the standard GT-R. 

Up front, lightweight aluminum 20 inch RAYS wheels wrapped in 255/40 Dunlop rubber cover massive 15.35” vented and drilled rotors with Brembo six piston calipers. This is matched with a double wishbone suspension, uniquely tuned for the Nismo with reduced weight and increased roll stiffness. In the rear, wider 285/35 rubber rides around 15 in vented and drilled rotors with Brembo 4 piston calipers. This is matched with an aluminum multi-link suspension.

 

2015 Subaru WRX STI + COBB Stage 1 Tune - Review

The 2015 Subaru WRX STI features a 2.5L boxer engine producing 305 horsepower. With AWD, limited slip differentials front and rear, and wide tires, it has plenty of available grip. Major changes for the 2015 model year include a more rigid chassis, stiffer suspension, torque vectoring, and a tighter steering ratio. Overall, the changes lead to improved handling and better steering. This particular STI also features a COBB Stage 1 91-octane tune, which improves low end torque and overall power. I also test the 0-60 times before and after reflashing the ECU. Is the 2015 STI better than the 2014, and how does it drive with a tune?

Drilled, Slotted & Vented Brake Rotors - What's Best?

When replacing your brake rotors, you may opt to upgrade to drilled, slotted, or vented rotors. Which brake rotor is best? What brake rotors will perform better? What are the best options for performance brakes? Ultimately, vented disc are great for heat rejection. Slotted rotors can aid in moving debris away from the rotor, and potentially adding a biting surface for the pad to contact. Drilled rotors aren't used in professional racing due to the stress failures they tend to have.

2016 Nissan 370Z NISMO - Review & Test Drive

The 2016 Nissan 370Z NISMO takes the 370 up a notch in terms of power and performance. It features a 350 HP V6 engine, improved aerodynamics for increased downforce, and NISMO-tuned suspension, front strut tower, exhaust, and stabilizer bars. Under the hood, there’s a 3.7L V6 engine. It features an aluminum block and heads, DOHC, 4 valves per cylinder with variable valve timing and lift, and a compression ratio of 11:1. The engine produces 350 HP @ 7,400 RPM (with a redline of 7,500 RPM) and 276 lb-ft of torque at 5,200 RPM. This is 18 more horsepower and 6 more lb-ft than the standard 370z, thanks to an exclusive exhaust design and optimized ECM tune.


MSRP As Tested: $46,835
