WATCH: $1500 for a LSD?!?! Why the OS Giken Super Lock Limited Slip Differential is worth it!

We recently installed an OS Giken Super Lock limited slip differential on our Project DC2 Integra! Watch as Mike Kojima explains everything you ever wanted to know about LSD but were afraid to ask! The OS Giken Super Lock 1-way differential completely transformed our Integra, and even at a price point around $1500, it's one of the biggest bang for the buck performance modifications you can do on a front wheel drive car- especially if you take it to the track!


 

Project Porsche 991 GT3 RS- Improving the Aero with a 911R Rear Diffuser

by Mike Kojima

How do you improve a supercar? It is not easy, but leave it to us to give it a try. We recently got to add a Porsche GT3 RS to our project car fleet. If you don't know much about Porsches, a GT3 RS is a limited production model, part of the current 991 platform family and the last of the great naturally aspirated 911's. 


 

Project DC2 Integra- Getting More Grip With OS Giken and Better Response With Centerforce

by Mike Kojima

With our DC2 Integra rocking a state of the art suspension, it was time to get our drivetrain in order for our anticipated track use and increased power. To get the power to the ground, we needed a limited slip differential, and we selected what we feel is the best FWD limited slip on the market- the OS Giken 1 way differential.


 

Dai Yoshihara's 2018 Formula Drift Rebuild

by Mike Kojima

After 3 years of Formula Drift competition, our team had pretty much developed the BRZ chassis to where we were satisfied with its performance. After some post-season testing to try out a few new ideas we decided that with the development stable, it was time to completely go through the car, repair some minor damage incurred during three seasons of hard use and to rethink the car's layout.


 

Project E39 M5: Yokohama Advan GT Wheels and & Nitto Invo Tires 

by Martin Gonzales

After installing the StopTech Trophy Brake System on our Project BMW E39 M5 we unfortunately, or fortunately depending on how you look at it, had to say goodbye to our stock wheel package. The OE mesh wheels were not designed to clear huge multi piston calipers and neither the front or rear wheels would clear our new brake kit. So we had no other choice but to do a long-needed upgrade to our project's wheels and tire package. Enter Yokohama Wheels and Nitto Tire!


 

Project DBA R35 GT-R: Putting the Suspension All Together With SPL Parts and Whiteline 

by Mike Kojima

Now we are in the home stretch for upgrading our GT-R's underpinnings with our quest to improve its on-track staying power and to reduce its propensity to understeer. In previous editions, we did the suspension basics and upgraded the brakes on the car. Now it was time to finish this part of our project off.


 

Building an FA20 Race Engine for Michele Abbate: Part 2

by Mike Kojima

So when we last left off, we were putting together some awesome parts for Michele's engine and were about to embark on assembling it. In the interest of long-term durability, we added a few tricks to our build over the last one we did for the Stay Crushing car.


 

Project S2000 AP1: Deatschwerks Fuel Pump Install

by Vincent Soto

All was not right with our Project AP1 S2000. It was making some louder than normal sounds that were coming from the fuel pump. The car would struggle to start as if the car had low gas or no gas at all. After some forum research and some diagnosing with a fuel pressure gauge, we had come to a conclusion that the fuel pump was bad.

After having the car for 5 years now, it was expected for it happen eventually. Since we got the car from the auction for 3200 dollars, there were no records of the fuel pump being changed or of any (well there was some records for tires bought in 2003) maintenance at all. With that being said, we started to look at fuel pumps on the market. In the end, we decided the go with Deatschwerks DW200 fuel pump (9-201-1000). 


 

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 E39 M5: StopTech Front & Rear Trophy Kit Installation

by Martin Gonzales

In our Brake Refresh Article we maximized the capabilities of our E39 M5's OE braking system by using StopTech's Sport Axle Pack, which includes slotted rotors, stainless steel braided brake lines and Sport brake pads. Front brake ducting was also added in order to improve on our project's susceptibility to brake fade. Though these improvements left us with a braking system that performed better than stock, the E39 M5's brake system has a lot of room for improvement. We will turn the knob to 11, with StopTech's Trophy kit!


 

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.


 

WATCH: Best New Stuff from the 2017 SEMA Show (Part 2)

Did you not make it to the 2017 SEMA show? MotoIQ has you covered! This year the show was full to the brim. We stopped by the booths of many of our supporters to give you an insider's look at their new products and technologies on display. Here are all the videos in one place, enjoy!


 

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!
