It’s our first installment of “Track Week” here at mentalgarage.com. If you couldn’t tell, as I type this I have a really itchy right foot. For our first installment we cross the pacific to Tsukuba Circuit.
Tsukuba is probably best known to internet junkies as the home of the Best Motoring Lap Battles rampantly found on YouTube. Aside from giving us state-siders some JDM carpr0n, it also hosts many local “tuner” events such as Time Attack and Drift. In fact, Keiichi “Dorifto/Drift King” Tsuchiya holds the track record, but I have a feeling he was doing so with more “grip” than “slip”.
Tsukuba Circuit is part of the larger Japan Auto Sports Center (the Tsukuba web address is jasc.or.jp), in Shimotsuma, Japan, just outside of Tsukuba. Time Attack and Drifting are a legacy of the original intention of the circuit, which was to attract a younger generation to motorsports. Today, the circuit also hosts events for the Japanese superbike and touring car championships.

From the map you will notice a smaller 1km gymkhana track just to the east of the 2km main track. If only Infineon Raceway had one of those to host our local SCCA events. Aside from racing duties, Tsukuba also serves as a test track to Japanese OEMs. In fact, Honda seems to have built a Tsukuba replica in Ohio!

Today we are going to kick off the suspension series for Project Pignose with a bit of a background and a mod primer. The goal is to help you backup some knowledge that you might already have and maybe teach you something you might not have thought about.
While there are certain characteristics that are unique to each individual car and chassis, there are a few basics that I believe carry across to all cars.
1. Know What You Are Tuning For
I believe a common mistake that many people make is thinking that buying the most expensive suspension that they can possibly afford is going to make for the perfect suspension for their situation. In the end you may have spent a few thousand dollars and still not be happy. Lay out your expectations whether it be:
Style + Comfort | ”Canyon Carving” | Autocross | Track Days/HDPE Events | Drift | Bling
External reservoir Ohlins may be complete and utter overkill on a show-only car, but what says “bling” more than coilovers that cost as much as a used car. I have two sets of springs for my coilovers: a stiff set for autocross season, and what my co-mechanic calls a “neutered” set for the less than ideal city streets of San Francisco. He also calls them neutered because I have two sets of springs because of my girlfriend’s complaints. Above all is the idea that the individual parts you assemble each need to contribute to the goal.
Also remember there’s a give and take for each choice. The hellaflush crowd goes for style, but to push the limits of offset and clearance without eating tires alive requires a very stiff car that may have your kidneys hating you if the roads in your area are less than ideal.
2. NVH
NVH: Noise, Vibration, and Harshness. Your car came from the factory aiming for a level of NVH that can be tolerated by the general public, or at least a niche thereof. This again goes with the idea of tradeoff. Camber plates may help you reach your desired alignment, but they contribute a fair amount to negative NVH for daily driving.
Most enthusiasts seem to have a higher tolerance for loud noises coming from their suspension, however, harshness is an extremely subjective measurement. What might be a tolerable amount of stiffness for your friend, may make you end up hating your car if installed on you’re own ride. If you’re unsure about a setup and you drive a fairly popular car, try to find someone on a local internet board and ask for a ride, perhaps in exchange for a 6-pack. Unless you drive a Neon SRT-4, most other car geeks are friendly people that like to help one another out (just kidding!).
3. Tires and Alignment
Before you go on an eBay shopping spree with your credit card, take care of the basics. Bigger sway bars and fancy shocks are probably not best complimented by a set of Big-O Tire specials. Sticky tires can go a long way on a stock suspension car. To make the most of your modifications, it then makes the most sense to make a good investment with the only parts of your car that are (hopefully) actually making contact with the ground. The heavier your car and the more crude your suspension geometry design, the more this holds true. Every autocrosser knows that tire pressures are crucial to the way a car grips and rotates, so don’t forget the “free” mods.
Many people also over look the importance of a proper alignment. Your relative suspension geometry “settings” such as camber, caster, and toe can potentially have a huge effect on the balance and handling of your vehicle. Some can be adjusted by an alignment tech and others not so much. If you have an adjustable ride-height suspension I consider this a very important factor in alignment as well. Your ride height determines a plethora of things in terms of ride quality and performance, be it from shock travel or the way the front end can “bite”.
4. Research, Research, Research
The internet is a-m-a-z-i-n-g and does wonders for making informed purchase decisions. There are a couple of important things to remember while doing this research: a) the credibility of the reviewer, and b) the end goal of the reviewer. Your friend with the Pep Boys special taillights could tell you that they are the best mod for your car and add 10hp, but should you believe them? Becoming a regular on enthusiast message boards is somewhat of a time suck, but after a while you can figure out who actually knows what they’re talking about. It is important to keep in mind, no matter how credible the source, of what the reviewer has in mind for their car. I can tell you my Vorshlag Camber Plates are awesome (they are) but I just might forget to tell you that outsized potholes might make your passengers think your car is falling apart. As an autocrosser I choose to tolerate these sorts of things, but for someone who will never see more than a twisty backroad, they may have a lesser opinion of bone jarring shocks. Research doesn’t just apply to quality and characteristics, but also price. A little bit of shopping goes a LONG way.
Hopefully this lays out a foundation for our next series of posts for the modification path for Project Pignose’s suspension. And if you have anything to add, be sure to leave a comment.
Project Pignose is an ‘06 WRX Wagon prepped for battling city streets and orange pylons.

As an American automotive enthusiast, it seems as if it is my job to complain about not getting uber cool models or variants on our side of the rim (or pond as it may be). From the point of view of an automotive product director, there is no way I would want to release an inexpensive, lightweight, rear-wheel drive coupe. People would drive them to the wheels fall off, and then quite literally buy new wheels for them, and drive them some more. How would we sell brand new cars then?
The AE86 is to drifting, as the Miata is to autocrossing. A well balanced lightweight car from the factory, that responds well to simple modifications. The Toyota Sprinter was a variant of the Corolla line, the most popular being that of the AE86 chassis designation. The “A” stands for the engine type (most well-known being the twin-cam fuel-injected 4AGE), the “E” stands for the Corolla model line, with “80″ representing the generation, and the “6″ being the 6th revision. The nickname hachi-roku is simply japanese for “eight-six”.
In an era where cars of its type were all losing a driveshaft in favor of front-wheel drive, the hachi-roku kept its rear-wheel format (with an optional LSD!) and was powered by the aforementioned 4A-GE featuring Toyota’s Variable Intake System. The car was offered in Levin and Trueno variants, the difference being between fixed and pop-up headlights, respectively.
CBY (Crystal Body Yokohama) AE86 Hachi-Roku
My gift to you on this Hachi Day is what is in my mind AE86 perfection. The Crystal Body Yokohama (CBY) Levin features some fatty fender flares and some mint Panasports to fill them. Some googling pulled up the following specs:
16×9 Panasport C8R
-6 offset front, -43 offset rear
225/45/16 Tires
I couldn’t find the tire model, but they look like Advan’s of some sort. Any other tire would probably be sacrilege. Panasports look so good on pre-90s cars, and the dish on these is simply amazing. Happy Hachi Day everyone!!
P.S. Levin FTW!

I stumbled upon the site damonproductions.com this morning, the site of professional photographer Tim Damon. I love a good portfolio, but DAMN. Check out the car portfolio. I have never seen anyone make a Chevy Cobalt’s interior look good.
Check it out.
And if you run across this… Kudos, Mr. Damon.

In the summer of 2005, my previous car was stolen, complete with many thousands in hop-up parts including a JDM Lip Kit, old school SSR Schumachers, and an E38 7-Series HID Conversion. So I should say my rice rocket was stolen. Insurance wrote me a handsome check just in time to purchase a car I had test driven about a year prior, only better. The new ‘06 Subaru Impreza WRX got a .5L bump in displacement, bringing it to a 2.5L Turbo Flat-4. The trade-off according to the Subaru community was having a face only a mother could love.
The timing couldn’t have been more perfect. The 2.5L models were on a boat from Japan. I needed a new ride. I wanted something with more doors than my previous coupe, something I could take with ease to go snowboarding, and something that had enough power that I wouldn’t want to modify it. The decision was easy given the parameters. A 230hp compact sport wagon with a near equal amount of torque. 5 doors and a turbocharger, who could ask for more? So with some aggressive dealing using my father’s proven automotive purchase tactics (more on this in a future post), I had the first 2.5L WRX Wagon to ever hit the streets of California, and perhaps the US for that matter.
As you can see from the pictures above, I did not keep true to my vow to keep the car stock. Over the next few weeks we’ll take a look at the modification path taken for Project Pignose, some of the technical details of those modifications, as well as show off some of the new parts going on in the next week or two. Of course there will also be constant updates as things get changed here and there. This is how things stand for now:
