Description

New Features:

In-line transmission:
In-line transmission, commonly referred to by racers as "straight transmission," was a top priority on our agenda. This innovation significantly enhances transmission efficiency and was essentially an obvious choice to implement.

New Chassis:

To facilitate the in-line transmission, a new chassis was essential. However, we didn't stop there after relocating all the major components; we also seized the opportunity to enhance the flex characteristics. The new chassis is 4mm thick in most areas and is designed without side dams. It offers the ideal flex for a race car that is both fast and easy to handle.

You can also adjust the rear flex by adding a small stiffener plate beneath the rear transmission.

We will additionally provide an optional 3mm chassis with distinct flex characteristics, which can enhance performance on specific tracks.

New Geometry:

Perhaps the most significant advancement comes from the revised geometry. In addition to adjustments in the roll center, roll center migration, and camber change, the narrower track width stands out as the most noticeable modification.

This geometry update has been crafted in close partnership with Andrea Catanzani and his father, Roberto. Another key aspect is the altered relationship between wheel and shock movement.

All New Suspension Brackets:

In essence, you can configure 15 different positions for the lower pivot using 7 various inserts.

Updated 2-speed Shaft Construction:

The updated gearbox includes the option to add weights into the shoes, resulting in faster and more consistent shifting.

Additionally, we've incorporated clips between the first and second gears to prevent the ball bearings from moving out of the second gear and causing the gearbox to "lock up."

Updated, stiffer bulkheads:

Our new bulkheads are constructed from ultra-stiff composite material, playing a crucial role in enhancing transmission efficiency. Additionally, we offer aluminum machined bulkheads as an option.

Main Features:

Adjustable Caster Blocks:

This impressive feature, which was introduced on the GT '23, continues to be a part of the GT R. The caster block is fully adjustable from 0 to 10 degrees in 2.5-degree increments. You can make adjustments using just two screws per caster block, allowing for quick changes in a matter of seconds.

The left and right side caster adjusters are laser etched for easy identification, making the adjustment process even more convenient.

Proven shock body, piston and Shaft:

Shocks are critical components in a model race car, as they influence nearly every aspect of handling and performance. Enhancing this area can lead to significant improvements in both the car's handling and lap times. These shocks have been tested and proven in the GT '23.

This high-volume shock is exceptionally smooth and plays a vital role in the overall performance of the car .

Heavy Duty Driveshafts:

With the tracks continuing to evolve as well as the developments in new rubber compounds for racing, the load has never been higher on the driveshafts than they are now. In order to meet the ever changing and demanding grip levels, we will use the proven driveshafts from the GT ’23 with a ball diameter of 10mm. With the additional diameter, the pin has more surface material to operate on, reducing wear on the internal slot’s surface This affect reduces a locking affect and increases smooth operation. While the diameter of the ball has been changed, the pin for the driveshaft has also been increased from 2.5mm to 3. The end result is a longer life, smoother operating driveshaft that is more consistent in a much broader array of conditions.

Differential and Pinion Height Adjustment:

Despite it being hard to believe, the SRX8GT R remains one of the few cars that offers adjustable diff height without altering any other geometry as a side effect. It features four adjustable diff positions and provides easy access to the differentials. These four adjustment options enable racers to fine-tune their model race car for various grip conditions, ranging from low to high grip.

Both the front and rear bulkheads utilize the same diff inserts and input assembly holders, minimizing extra parts and maximizing your racing enjoyment. The diffs can be removed and replaced in just seconds, giving you every reason to refresh, fine-tune, or rebuild your differential as needed.

Fuel tank:

The kit includes a tried and true 150cc fuel tank. The tank also includes a plug in case you need to adjust the capacity plus or minus a few cc. The tank has clip on clamps to help keep your fuel line in check as well as an overflow/splash shield around the lid of the tank. The tank floats on two specially design posts to flex just enough but also provide the proper support. The tank then has 2 rubber grommets to absorb vibration from the engine to reduce air bubbles in the tank to further improve the performance of your fuel system.

Symmetrical rear Transmission Braces:

At the back of this asphalt-slaying machine, we've focused on achieving as symmetrical a flex as possible. Testing has demonstrated that this design positively impacts lap times and improves handling when cornering left and right. The SRX8GT R features two short braces that are symmetrically mounted just behind the engine.

Easy Access Center 2 Speed Assembly:

While the 2-speed system has been enhanced, it still retains the easy access feature. By removing just two screws, you can quickly take the entire 2-speed out of the car, making adjustments and maintenance super fast and straightforward.

In addition to the easy access 2-speed, you can achieve maximum performance from your braking mechanism thanks to a simple, adjustable single 3mm turnbuckle. Say goodbye to unevenly worn brake pads or overloading one pad; you can get it right the first time with ease. With class-leading technology like this, you'll enjoy working on your new GT

Adjustable Flex suspension arms:

The front and rear suspension arms are constructed from a more rigid composite material, allowing for a broader and more practical range of adjustment. The arms feature cover plates that can be added, removed, or replaced with Carbon fiber options. This versatility serves multiple purposes, including aesthetic enhancements and performance improvements.

Depending on your grip level and track surface, you can modify the stiffness of the SRX8-GT’s arms. Generally, stiffer arms provide a more linear response but may reduce grip, as they increase the workload on the shocks. Conversely, softer arms can enhance grip by lessening the shocks’ influence, although they might make the car feel less direct.

These adjustable features can significantly influence your lap times and overall performance.

HTD High Volume Differentials:

We have retained the ultra-reliable and proven differentials from the GT '23. The internal gears feature an impressive Mod 1.25, making them some of the largest in the marketplace. With maximum engagement surface on the tooth and larger volume housing, these differentials minimize fading or loss of performance

The internal ratio is set at an industry-standard 10/20.

High Performance Adjustable Clutch:

Also included in the SRX8GT R is the Adjustable GT clutch set, this was used for the first time at the Worlds and was proven to be the best available clutch on the market. This clutch has come a long way from our original 4 shoe spring loaded clutch. It offers amazing reliability, tune ability and literally puts the power down to the tarmac. This clutch will not disappoint.

Aluminum upright with carbon brackets:

The aluminum uprights open the door of infinite possibilities. Not only can we adjust the Camber link position in new areas we have never before, they also retain the original geometry you might already like. This new design gifts us the freedom to quickly change the geometry on future versions if necessary. The latest geometry has been tested vigorously and proven race result after race result, it works. More traction and better tire wear over long mains.

Oversized Front Bumper:

We supply an oversized large foam bumper in the kit. The bumper is firmly mounted between the upper and lower bumper. This solid mounting allows you to take more direct impact and ensure your car will be properly protected. The bumper can be trimmed to fit most if not all bodies currently in the market.

Ball Raced Sway bars:

If you have a good thing, let’s keep it going... That is exactly what we did with the ball bearing raced sway bars. We introduced this first the 1.8thoffroad and then followed that up into GT.

Both the front and rear suspension will get the same treatment. The sway bar will be securely fastened and the left and right play can be adjusted. You can be rest assured there is not un-necessary friction and your roll bar is fully operation when driving your race car.

Adjustable and lockable Body posts:

The Gt also comes with fully adjustable front and rear body mounts, and platforms. The platforms are oversized to make sure the body had plenty to rest on and held in place with a sold metal pin. The posts themselves are extra-long so that they can be cut to length depending on what body you prefer.

The posts themselves have many holes in them to select the height you need and are locked into position by way of a 10mm cap head screw. This locking will prevent the body from adjusting in a collision or crash.
