Getting started: Wheels, tint, and more

The 2015 WRX stock wheels aren't bad looking, but neither are they particularly noteworthy.  They're of modest size (17x8") and the dark gray color makes them sort of hard to see, especially on a light-colored car.  I just happen to know a nice large-size wheel that should bolt up nicely...that's the Mach V Wicked Awesome, which is 18x9.5" and a nice light 19.0 pounds.  A set of Hankook Ventus Evo V12 tires, 265/35R18 size, are exactly the same diameter as the stock tire, and 30mm larger in terms of tread width.  And even with significant increase in contact patch, we actually LOST 0.1 pounds of weight per corner!  What's not to like?  Plus, I think the wheels look great.  We did fit up two different colors -- silver and gold.  Which do you like better?

Since you asked, yes, I am looking to sell the stock WRX wheels, so ring me up at the shop if you are interested.  I'm open to selling them with or without the stock Dunlop Sport Maxx tires.

Other early modifications to the car include an all-around window tinting treatment from Matt at TNT Tint, and clear paint protection film applied by Dave at Proshield.  Do look them up if you need either service done, and tell them I sent you.

Next up for customizing was the audio system.  I spend a good amount of time in the car, and I do like my music, so I headed over to KarTunes, just around the corner from our shop, for some upgrades.  Mike and Dan were more than welcoming, and from talking to them they clearly like their work and bring a lot of knowledge and enthusiasm to the job.  They suggested I bring in my own iPod, and I was able to plug directly in to a display board in the showroom and audition the speakers with my own music.  After a bit of listening, I settled on some Focal drivers.  Focal PS 165 FX speakers went into the front doors and dash, and Focal 165 AC speakers filled in the back doors.

None of the usual suspects make a pre-made sub box for this car yet, but Subaru does offer an OEM amplified Kicker subwoofer.  We used the molded-plastic box from that, tossed out the Kicker driver, and put a JL Audio 10W0 sub driver in there.  The box was a little ringy at first, so the KarTunes guys applied a layer of sound deadening material inside the box.  That tightened up the bass nicely and cut down on unwanted resonance.

For amplification, KarTunes installed a couple of older JL Audio (300/4 and 250/1) amps I had saved just for this occasion onto a custom board on top of the factory spare tire.  The factory head unit was left alone -- it fits and is functional enough, and offers nice integration with the steering wheel controls.  A bonus, and something I didn't realize at first, is that the WRX upper dash info screen has a page that will display current song information sent to it from the head unit. Cool!

The end result is super-clean sound, with very tight bass and terrific clarity and separation.  I never did put any sound upgrades in my 2008 STI, and I always missed having really nice music in that car.  I can tell already I will really enjoy the chance to hear great tunes in this one.

New car, new platform, new engine, new adventures!

Welcome to our latest blog, which is about our latest Mach V shop car, a 2015 Subaru WRX.  This blog will follow the modification of the car over time, and will share plenty of other observations and discoveries about the car.

First I should answer the question everyone asks about it, which is, "Why didn't you get an STI?"  We didn't because the WRX has a brand-new turbocharged variant of the FA20 engine that first appeared in the Subaru BRZ/Scion FR-S twins.  (We happen to own a BRZ shop car, too, which you can read about in another blog.)  The FA20 turbo is a fully direct injection engine -- not the hybrid port/direct setup in the BRZ.  All this is important to us because while the STI still soldiers on with the same EJ25 engine we've been working with since 2004, the FA20 DIT (Direct Injection Turbo) is all-new and I want to get started tuning on it.

Sure, I miss the direct-feeling and nearly-indestructible six-speed transmission that goes with the STI engine, and the Brembo brakes, and that fancy DCCD center diff from the STI.  But besides having the new engine, the WRX is about $8,000 less expensive.  That's a lot!  In the old days (like 2008), the gap between WRX and STI was huge.  The WRX had skinny body work, skinny tires, a weak 235hp, and tiny brakes.  Now the WRX gets the same wide bodywork as the STI, gets decently-fat 235mm tires, big (if squishy-feeling) brakes, and has 268 hp.  The difference between the two cars has narrowed, at least on paper.

Our car is a Limited model, which means it has LED headlamps (wait, let me say that again: LED headlamps!), leather-trimmed seats, a power-adjusted driver's seat, plus all the stuff in the Premium model, which includes a moon roof, trunk lid spoiler, fog lamps, and heated seats/mirrors/wipers.  Of course, we got the six-speed manual.  (You can pry my manual shifter from my cold dead heads.)  Speaking of cold and dead, though, the stock shifter feel on this car isn't too great.  I understand it's a new cable-actuated unit, and shifting it kind of feels like you're stirring pudding with a really long length of PVC pipe.

We bought the car from Heuberger Motors in Colorado Springs, CO.  We got an amazing price on the car, and the transaction was very straightforward.  They even arranged for delivery right to my door.

We don't plan to run the car on the dyno just yet -- I like to follow a factory-ordered break-in schedule -- but we will be swapping on some Mach V Awesome and Wicked Awesome wheels right away, with the goal of reducing weight and increasing the tire contact patch.  I'll post photos when that's done.
