The Ultimate Guide to Suspension and Handling - Bump Steer/Toe Steer

by Mike Kojima

It's time to think about suspension.  Some of the most common handling problems that you are the most likely to see on modified street cars and race cars based on production chassis, especially in racing classes that do not allow relocation of suspension pick up points are bump steer and toe steer related handling issues.  Bump and toe steer can have significant negative effects on a cars handling which is manifested by steering pull, twichyness, instability, steering inaccuracy and unpredictability.  All of these things are scary for drivers to deal with

Project Garage Part XII: Liquid Magic

by Sarah Forst

Who among us has not identified a fluid on the driveway or garage floor by color, smell, or even taste? (Don't drink the Kool-ant...) At any rate, you know you're a true gearhead when the intoxicating scent of a fluid can conjure up memories of changing transmission fluid or bleeding brakes. The only way to consider yourself an expert is if you have a few stock ingredients in your garage pantry. And not just the ones required for maintenance or to keep your engine running, but the ones that you need to clean up after yourself too. Find out what Project Garage uses.


 

Project Ford Fiesta ST - Improving the Shifting with mountune

by Mike Kojima

Although the Fiesta ST has fairly decent stock shift feel, which is quite positive for a cable shifter FWD car, we still thought that the longish throws could be shortened for a more performance oriented shift feel.  Traditionally we have never been fans of short shifters that the aftermarket is full off. Your typical short shifter shortens the throws too much destroying shift feel as well as sometimes overstressing syncros, to the point of damaging them.

With this in mind we were somewhat reluctant to install mountune's short shifter developed for the Fiesta ST.  If you haven't heard of the name mountune, it's because in this country tuning of Ford's FWD offerings has not been the popular thing to do.  Not so in Europe where compact Fords have been a mainstay of the enthusiast market for 3 generations.  In Europe the name mountune is closely associated with Ford Performance and with the new Fiesta and Focus ST mountune will become a mainstay for Ford performance in North America.

It's All About the Zinc - High Stress Wear Resistance with Penrite Oil!

by Mike Kojima

We get a lot of oils and lubricants to evaluate at the MotoIQ office and for the most part we have had good results with the latest high quality synthetic motorsports oils that come across our desks and into the crankcases of our various race and project cars.  When it comes to quality oils we get pretty uniform results, clean burning, low deposits and good wear of the engine's internal components.


 

ARK Team America BNR32 GT-R Update Teaser

by Mike Kojima

An update has been a long time in coming but it is true, the ARK Team America BNR32 has not gone away or died, it's just that all of the principals have been busy with our other motorsports and industry jobs ranging from ALMS to Formula D.  With all of us so busy working the car kept getting pushed off but lately Eric Hsu has been rallying the troops and work has been progressing on the car all summer.


 

Project Ford Fiesta ST - Improving the Handling With ST Suspension

by Mike Kojima

If you love performance compact cars, then you should really be paying close attention and focusing your next purchase intent on The Ford Fiesta ST.  The Fiesta ST is basically the same joint Ford, Mazda 2 platform that we loved so much as a B Spec racer.  We felt the chassis handled well but was lacking power in gobs.  Well Ford fixed the problem in a big way with the Fiesta ST by dropping in a turbocharged direct injection Ecoboost 1.6 liter engine with a six speed manual transaxle that delivers 197 hp and  good mileage together in a package that leaves you grinning from ear to ear.

What the F-Stop: Event Coverage from Behind the Camera Lens

by Sarah Forst

There's just something invigorating about the smell of race gas in the morning, the smoke produced by tires screeching, and the high pitched wail of a high horsepower engine going all out. And while I'd love to be on track owning that racket, I am just as excited to be covering it from behind a camera. From Formula Drift at Road Atlanta to 24 Hours of Nurburgring, my lame attempts at photography ("needs more blur"- thanks Jeff!) have taken me places I couldn't have dreamt about being so close to the action. And at the end of the day when I'm covered in rubber, drenched in either sweat or God's tears, and have claw hand from holding the camera grip for hours, I still have a smile on my sunburnt face.
