The Kyosho Inferno GT3 1/8 Nitro 4WD On-Road Touring Car Kit is the ideal model to compete in the 1/8 GT class. Based on the Inferno MP9 TKI4 1/8 GP buggy, the GT3 represents a complete change from the previous Inferno GT2. Advanced specifications deliver incredible performance thanks to short Big Bore Shocks and machine cut Duralumin shock mounts, a lighter diff, optimized weight distribution and improved braking. All of these traits are combined to create the durability and reliability needed by competition racers throughout a long race. The GT3 is the next step in the evolution of the 1/8 GT class, and is fully equipped to compete and win at the highest level.

Kyosho Inferno GT3 1/8 Nitro 4WD On-Road Touring Car Kit
I got this kit from my local hobbyshop.

This is a wonderful kit that is well built and goes together smoothly. The instructions are decent, but would be harder to follow if one has never built a kit before.

One thing that I like is the cross-platforming with the Inferno MP9 TKI4. This allows for many parts to be interchangeable/upgradeable with readily available parts. For example, I was able to use the 8 hole MIP bypass kit from the MP9 TKI4 as opposed to the 6 hole included with the kit. This will allow me to run a slightly heavier shock fluid and still get the same roll speed, with increased rebound.

There were two things that bothered me about this kit, however. The first is the lack of "option parts" that should be standard for a kit of this calibre. For example, the kit does not include 4 degree caster blocks (not even composite ones), which most forums agree are necessary for this car to be competetive and make for an all around better driveing experience. Also, the only 4 degree blocks that Kyosho makes (IGW061) are extremely difficult to find. I had to get mine from Austrailia with an obscene shipping cost.
Another example is the omission of aluminum arm swing mounts, as the kit only includes the front lower mounts and inside rear mount as aluminum. The rear toe arm holder and the front upper arm holder were composite.

The second thing that bothered me is the composite spur gears. This issue is just a personal preference of a steel first gear spur, which was fixed with a GTB steel first gear hop-up.

The only issue that I had with the building of the car itself was with the spacers used for the front upper control arms. The kit says to use two of the thin spacers, but that left way too much play-especially for a new car. I used the two thin spacers with one big spacer. Although the fit is close, experience tells me that once the car is broken in there will be just enough play for free movement but not enough for slop.

I also opted to install the aluminum chassis braces (both front and rear) while building the car. This is a personal preference, however, as I like the feel of a ridgid on-road car.

I do not race competively, but I love a quality kit due to the durability and consistancy they provide. Since I do not need to follow IFMAR or ROAR rules, I decided to pair the GT3 with an O.S. R2104 9 port racing motor designed for pan cars. As excessive as it sounds, I also opted for Futaba's HPS CB-701 servos.

Overall, I am rating this kit as a 4. If you are thinking about buying this kit vs. the Inferno GT2 Readyset, I would insist that this kit comes with enough of an upgrade of parts as to warrant the price difference, but does not come with the parts that I would expect of a kit for this price range-especially since the 4 degree caster blocks are considered by many to be "essential." Hence, I am docking a half-point. The other half-point is being deducted for the instruction manual not being "beginner-friendly." Other than that, this kit is a solid 4, and can be a 4.5 with the proper caster blocks and aluminum arm mounts.
