Project EP3 Civic Si: Why the Suspension Sucks and How to Fix It! 

Since us MotoIQ nerds have a heightened perception of what is "an acceptable" level of handling in a car, we realize that we bit off quite a bit to chew with (arguably) Honda's worst handling Civic- the EP3 generation. What have we done to correct it and did it work? Watch to find out, with MotoIQ's chassis engineer, Mike Kojima, and test driver, Karla Pestotnik!

Project Golf R MKVII: Finding More Power with COBB Accessport

by Isaac Sandoval

In our last update on on this project, we started preparing for power modifications by installing a Fluidampr crankshaft pulley. That modification went much better than expected with the car picking up a few horsepower in the process. Despite that small bump in power from the pulley install, having near stock power levels on the Golf R all this time has definitely become a little bit boring, especially knowing the potential of the hardware under the hood. We have been waiting patiently for COBB to release their Accesstuner for the Golf R, and they have finally delivered. The Accessport tuner and hard parts are now available for the MKVII Golf R, and we are going to test out the gains on our Project Golf R.

Project BOSS 302Revival: Introduction

by Mark Gearhart

Sometimes it’s a disgrace to let a vehicle perish. When crashed beyond their means, some vehicles can cost more than it’s worth to provide a second chance at life. After seeing a 2013 BOSS 302 that was destined to be parted out and discarded, we knew this one couldn’t be left to the vultures. Meet MotoIQ’s latest project vehicle, Boss 302Revival.

Project DBA R35 GT-R: Upping Stopping Power with Brembo and Race Technologies

by Mike Kojima

As you can see so far in this series, we are doing a lot of things to fight the weight of the GT-R.  At 3800 pounds, the GT-R wheels throw around a lot of mass with a great deal of speed and grace, but it can only do it for short periods of time before the weight takes its toll, mostly on the brakes and tires.

Project DBA R35 GT-R: Getting More Grip with Advan and Toyo!

by Mike Kojima

One of the issues with the R35 GT-R is that it is a big heavy car that gets an amazing amount of performance out of its tires.  The stock tires are a 285/35-20 in the rear and a 255/40-20 in the front. For most cars, this is an impressive amount of rubber but for the 3850 lb GT-R, the car works exceedingly well at first, but the tires quickly fade away.  With some ham-fisted driving, the fading away happens pretty fast.

Project Corvette Stingray C7 Z51: Keepin' it Cool(er)

by Mike Kojima

Corvettes have always been notorious for overheating on the track. The Z51 shod from the factory with additional cooling capacity is much better in this respect, but it can still run hot under the worst conditions. For this reason, Chevrolet has come out with an auxiliary radiator kit to supplement the engine cooling on the C7. Since we plan to drive our car on the track, you can bet we are going to install this!

Project DBA R35 GT-R: Getting the Ultimate Custom Car Cover with Covercraft

by Mike Kojima

The MotoIQ Megashop is in a pretty dusty industrial area in So Cal. Dust gets into our shop and mixes with the normal shop dirt of metal filings and other stuff that naturally flies around when you work with cars.

So unfortunately, some of the nicer cars in our fleet end up being quickly covered by a mixture of nasty shop dirt and neighborhood dust that can turn a freshly cleaned and detailed car into a pigpen in as little as a week.

Project C7 Corvette Stingray Z51: Drivetrain Improvements

by Mike Kojima

The C7 Corvette is truly an exotic car, and we cannot believe the amount of state-of-the-art super trick features it has to offer for the price it commands. One of these features is its rear-mounted transaxle.  Mounting the heavy transmission in the rear of the car and combining it with the differential is a cool way to save weight and helps the Stingray achieve its 50/50 weight distribution.

"My Fiancée's" Miata: Part 9 - V8 Roadsters Cowl Stabilizer Braces, Sway Bar End Links and Track Test

by Daniel O'Donnell

Last winter, I was debating all the areas of improvement the Miata needed and first and foremost was chassis rigidity. The car crashes over bumps, the interior rattles and the cowl shakes like an old man’s fist when the neighbor kids are playing ball too close to his roses. It was getting to me and really needed to be the focus for improvement before future modifications could be made. Much like a relationship, a chassis needs to be rock solid for the whole package to work. My fiancée will appreciate that part.

Project DBA R35 GT-R: Starting the Suspension Revolution with KW Suspension and Forged Performance

by Mike Kojima

It's been a long time since we even mentioned anything about our Project R35 GT-R. We had plans for the car but never could find the time to work on it. The other issue was that the R35 is a world-class supercar, and it is very hard to improve on a car like this without messing it up. It is easy to make it worse with ill-conceived aftermarket parts.

Project Vehicross Part 8: Pinion Angle 101

by David Zipf

It’s been awhile since we’ve done anything with our funky Isuzu project. There’s a simple reason for that: I was planning to replace it with a Mazdaspeed 3 (in 2016) and have a fun, practical, and incognito hatchback to replace the fun, tough, and weird Isuzu. Due to a series of unfortunate events (some relating to a lazy previous owner, and some relating to unfortunate shortcomings in Mazda’s quality), we decided to offload our 3 and keep the Isuzu. That meant dealing with some of the issues we’d been ignoring for months while we fussed with the Mazda.

Project Corvette Stingray C7 Z51: Body Modification

by Mike Kojima

Typically aftermarket aero parts are lame; they don't fit and have gaps. They require you to drill holes in your body panels for sheet metal screws. The carbon deteriorates in the sun and gets cloudy. Not so for these Chevrolet Performance offerings. They fit perfectly and are built to the same OEM durability standards as the car!

"My Fiancée's" Miata: Part 8 - Whiteline Roll Bars and Track Test

by Daniel O'Donnell

In Part 6 of our ongoing Miata project, we got to spend a lovely day tracking the car and finding out its good and bad traits. One of the most glaring problems, at least from the driver’s confidence standpoint, was a massive amount of body roll in the corners. Body roll, in and of itself, isn’t necessarily the worst thing in the world, especially as our Miata is at the stock ride height. It didn’t appear that we were running out of shock travel and we didn’t notice any exaggerated or strange tire wear, confirming that the suspension was working more or less as designed. That being said, it didn’t exactly inspire confidence. The car would set into a turn and take significant time to transfer load if I had quickly change directions. To improve the dynamics of the Miata and not feel like we’d roll over and off the track, the body roll had to be rectified.

Project E39 M5: K&N Filters and HPS Intake Hoses

by Martin Gonzales

In this installment of Project BMW E39 M5 we will test two very easy to install intake upgrades- the high flow K&N drop-in filters and HPS Performance Parts silicone intake hose kit. We will be doing individual dyno tests for each part to see if they can free up the S62's intake tract and yield some measurable power gains.

Project C7 Corvette Stingray Z51: Suspension Upgrades

by Mike Kojima

In previous articles about our Project C7 Corvette, we got into the high tech chassis construction of the C7 that rivals the stuff found in exotic cars for a fraction of the price. We also did our baseline testing of the car at Buttonwillow Raceway to get an initial impression of the car. We were quite impressed with the results. In stock form, the Corvette is one of those cars that is so good from the factory that heavy-handed, poorly conceived aftermarket suspension mods can ruin.

Project Sim Racer: Part 4 - Project Cars 2 Review

by Erik Jacobs

Having constructed a quality sim rig and then upgraded it with even better controls, I’ve spent a fair bit of time putting in laps on both iRacing and rFactor 2. A while back, an associate offered to make an introduction to the folks at Slightly Mad Studios, the creator of Project Cars. The introduction came very early in the development cycle of Project Cars 2, but the conversation was fruitful. Not long after the release, I received a copy to review.

Project AP1 S2000: DIY Oil Filter Stopper 

by Vincent Soto

Most S2000 owners know about the oil filter problem on AP1 S2000's. At high RPMS, the engine vibration causes the filter to loosen up (our Project AP1.5 S2000 knows this well, as the F22 swap happened due to this happening on track with the original F20 engine). After a nice Sunday drive, before heading home I decided to check the oil. A gut feeling casued me to check if the filter was tight- which is a good thing that I checked because it was loose. After re-tightening the filter, I was back on my way home- only to find it slightly loose again.

An inside look at the Feal 441 Suspension for the B13 Sentra SE-R!

by Mike Kojima

The original B13 Sentra SE-R has always held a dear spot in many of our hearts. Produced from 1991 to 1994, the SE-R combined the lightweight shell of the Sentra coupe with the sparkling performance of the beloved SR20DE engine. For its time, the SE-R offered a great performance bang for the buck, and to this day, it has scores of hardcore devotees who treasure them.
