Project C7 Corvette Stingray Z51: Improving Stopping With a Chevy Performance Big Brake Upgrade Kit

by Mike Kojima

When we did our baseline test of Project C7 at Buttonwillow Raceway configuration 13 CW, we were pretty impressed with the stock Z51 Stingray's on-track performance. We felt the chassis was set up pretty well for the wheel and tire configuration that came on the car, and the whole chassis calibration was matched to the amount of tire the stock car had and the power level of the engine.

Project Golf R MKVII: Fluidampr Test

by Isaac Sandoval

The Golf R is back for another round of modifications. Now that we have addressed the suspension and feel the car is handling the way we want it, it is time to move on to the powertrain. We are not entirely sure which direction the powertrain modifications will ultimately go, but the best place to start is by making sure our foundation is solid. In this article, we are going to be installing the Fluidampr crankshaft pulley, as well as doing some baseline Dyno testing on Project Golf R.

Project DC2 Integra: Truing up the Suspension with Whiteline

by Mike Kojima

In the last edition of Project DC2, we greatly improved our car's suspension by replacing the ancient, worn out Koni Yellow shocks with some state of the art street KW Suspension Double Adjustable Variant III coil-overs. When paired with a stock front anti-sway bar and the excellent Comptech rear anti-sway bar that came with the car, we had a well-balanced combination that worked pretty well on the track and the street.  

All was good, but we wanted to go through the entire suspension and replace all of the old and well-worn rubber bushings in the car with new, hard polyurethane parts from Whiteline. This would bring our suspension up to snuff with the current best stuff out there.

Project AP1 S2000: Installing Hasport AP Differential Mounts

by Vincent Soto

Our Project AP1 S2000 is a daily workhorse. It’s almost 17 years old and is coming up on 140,000; the car has been a good reliable daily driver that sees some spirited driving every now and then. 

Recently, we discovered that the differential mounts on Project AP1 S2000 were torn and started to leak. Instead of going back to the OEM liquid filled mounts, we decided to just go with a more solid mount. After driving Project AP2 S2000 and feeling how well the Hasport mounts felt, it was a no brainer to go with them again!

Project GD STI: Making the Front of the Car Stiffer with Ultra Racing

by Mike Kojima

In the last installment of Project STI, we had greatly increased the chassis stiffness with a full complement of Cusco braces. From our EVO project, we had found that on the CT9A chassis, the braces that did the most were the fender braces that add reinforcement from the strong door hinge area to the top of the shock towers. From this experience, we wanted to add similar braces to our STI.

Project Tundra: 5000 Mile Evaluation of Nitto's New Ridge Grappler Tires!

by Mike Kojima

We were very pleased with the Nitto Terra Grappler tires that Project Tundra had been running the last 7 years. We had over 60,000 miles of towing, supercharged burnouts, daily driving and off-roading on them- including a day of driving hard around Willow Springs Raceway. We were very pleased to note that they still had at least 70% of their original tread and still worked quite well!

Project GD STI: Getting Rid of Chassis Flex with Cusco

by Mike Kojima

The GD STI/WRX had what was considered to be a very stiff chassis when it was first released internationally in 2000. The new Impreza platform was built to be much stronger than it predecessor and used much of the experience gleaned in rally competition to build a chassis that was over 100% stiffer than its predecessor. However, that was 17 years ago, and the design that was once the leading edge in unibody chassis integrity is now something that is just average.

Project SR E30: Part 1 - Test Fitting the Engine

by Nikita Rushmanov

So, you built an s13 daily with an SR20 in it. It’s reliable, it’s fast, it makes awesome chu-chu noises, you put 5,000 miles on it, but then you realize that there is one thing this car doesn’t have- 4 doors. That is the exact predicament we were in.

Project Bugeye GDA WRX: Fixing the Clutch with Exedy

by Mike Kojima

Poor Ian, MotoIQ's FNG's daily was his trusty Bugeye GDA WRX. The WRX has given many years of faithful service, but since joining the MotoIQ crew, Ian's commute has gotten much longer and the miles were taking their toll on the car which has over 200K miles. To make matters worse, on his way to work, the car sprung a huge oil leak and oiled down the super old clutch, and Ian barely limped into the MotoIQ garage.

Project EP3 Civic Si: Fixing the @$#%! Steering for Good with SHG Motor Works!

by Mike Kojima

In our last edition of Project EP3 Civic Si, we thought we had fixed our car's bump steer and wandering steering with a roll center correction kit and a bump steer kit from Hardrace. Our car had serious issues since day one. When we first got it, no one wanted to drive it because the car would wander around on the freeway and everyone was afraid of getting pulled over for drunk driving.

So, we installed a bunch of suspension stuff and finished it with the Hardrace geometry correcting parts in the front suspension. With the car finally handling well, which is no small task with an EP3, we were finally having fun driving it hard. All was good for a couple of weeks, but then the wandering steering returned with a vengeance.

Project G37S: Survived the 2017 Phoenix Monsoon

by Aaron LaBeau

Imagine what you think Phoenix, AZ looks like in August, and unless you've lived in the area or visited after mid July, you'd probably have the wrong image in your mind. Replace that dry and 115 degree thought with microburst type rain that drops inches of water in a matter of minutes. What started out as a normal afternoon commute home ended up as a serious choice of whether or not to drive.

WATCH: Project C7 Corvette Stingray Z51 Baseline Track Test 

So, you read the Part 1 of our introduction to Project C7 Corvette Stingray and probably watched Mike Kojima give us all of the engineering explanations under the chassis. You even read the in-depth breakdown of the LT1 engine. All of this information is great, however, what does it mean for the performance on a racetrack?

We gave our test driver, Karla Pestotnik, a few hot laps to give us some insight and a baseline lap time before we add any performance upgrades in 100% stock form. We hit the tarmac with our friends at Global Time Attack at a Buttonwillow Raceway 13 CW (clockwise) configuration time attack event.

Project DC2 Integra: Starting the Journey Toward Better Lap Times with KW Suspension

by Mike Kojima

If you've been paying attention to our DC2 project car, then you know in the last installment we took our car to Buttonwillow Raceway (CW13) to record its baseline lap times and to get some driving impression of its 150,000-mile suspension and tires. Surprisingly the old DC2 was not horrible and not the slowest car entered in Global Time Attack's first ProAm event of the year. 

However, we never settle for "good enough" at MotoIQ, so we're outfiting our Integra with a set of KW Suspension Variant III coilovers as we embark on the journey towards better lap times.

Project GD STI: Making More Power with Cobb Tuning and Precision Turbo Part 2!

by Mike Kojima

When we last left off with Project GD STI, we had just installed our drop-in ball bearing center section upgraded Precision Turbo. In our opinion, this is one of the best drop-in, non rotated mount turbos on the market for these cars, however, we wanted to be able to turn the boost higher. This brought the need for a tune utilizing Cobb Tuning's Subaru Flex Fuel System.

Project C7 Corvette Stingray: Introduction Part 2, A Closer Look at the LT1 Engine

by Mike Kojima

In the last edition of Project C7 Corvette Stingray, we were doing an overall look at the car including it's mostly all new LT1 engine. As we were saying, although the LT and LS share the same architecture, they are indeed very different engines. They are so different that they only share a handful of parts. 

The LT1 is a vastly different engine that has a lot of development differences over the already excellent LS3 engine and deserves a closer look at some of its unique internals. Most of the differences are to improve fuel economy, emissions, torque and powerband width, but there are are some tweaks to make more power overall as well. Take a close, detailed look with us!

WATCH: Project C7 Corvette Gets an AEM AQ-1 OBDII Data Logger! 

Just like Project DC2 Integra last week, we're taking our Project C7 Corvette out to Buttonwillow in 100% stock form for some lap testing courtesy of our friends at Global Time Attack.  Unlike the Integra--who's too old to know what a CANbus is--we're installing an AEM AQ-1 OBDII data logger in the Vette before we hit the track.  AEM's AQ-1 OBDII Data Logger is easy to install and logs engine data transmitted from the CANbus signal feed in the OBDII port of any 2008+ vehicle.  The AQ-1 also has a 3-axis accelerometer built in so we'll be able log g-force data as well!  Take a look at today's video to learn more about it and see how easy it is to install!  And remember to swing by again next week for the results of our C7 baseline track test before we install all the Chevrolet Performance parts heading our way!

Project V8 RX-7: Part 17 – Eimer Engineering Arms, Wheel Spacers and the Hunt for Perfect Stance

by Mike Kojima

In our last articles about Project V8 RX-7, we left you last with photos of our new SSR Professor SP4 wheels and Toyo R888 tires looking flush, but we weren’t ready to explain how we accomplished that task yet. With our Rocket Bunny aero kit giving us a huge space in the wheel wells to fill, we were going to take advantage of all of that.

Our car had to use all of the space for wide wall-to-wall rubber. More rubber means more grip, and with our LS3 providing the torque and power to use it all, we were obligated to do so. However, just putting wide rubber on a car not designed for it creates a few technical issues that, since we are MotoIQ guys, have to be engineered out of the equation. This means the typical spacer to fit and beat to match approach was not going to be a solution.
