The perfect composition of surface, starting with negative R then smoothly transitioning to flat and finally coming to positive R, it’s so fitting and best matches with the positive R you can see in Front Bumper "Bonnet" Front Fender area line. Our front bumper also adopts genuine combination lens of Type 997 which only adds the authentic flavor to it.

   

Not to be underestimated, we have put as much research and passion into functionality. JNH’s font bumper can be bolted-on to the under panel to fully ride on the beauty of original flat bottom. By lowering lip section by 20mm to create an upsweep, downforce is vastly improved. The straightforward stability and the road-hugging performance are achieved by adopting large canard design on both sides that erase the ever-lasting fear of RR Porsche that the more you accelerate, the lighter you feel at the front.    


In terms of cooling effect, large ducts are efficiently in place at center and side section, which along with elaborately designed approach of the bumper, improves the cooling by 30 %. Carbon Center Duct Fin, which comes with the Front Bumper, is developed to accelerate the flow of air and the driving stability, can be attached upon your request.


At the initial developing stage of Side Step, we have decided to go against the common approach of decorating and dressing-up….what we proudly presents as JNH’s Side Skirt and Carbon Splitter is the end result of extensive research and continuous pursuit of aerodynamic effect.


It can be attached to the original body without the trouble of custom fitting. But the secret here is at the bottom. The aerodynamic strake, designed to stream accumulated air to the rearward, is only visible when you actually kneel down. Only the owners know it’s there and experience how it works.

   

GT3 Side Step


Looking on the outside, carbon splitter is mounted on FRP Skirt which embodies the speed and thrill of racing. Each part is firmly connected by antirust titanium joint rod. This splitter dramatically improves the flow of air and along with aerodynamic strake, reduces the air pressure on rear tires to the minimum.


It usually starts with design and ends there. Not a possibility with digital design, it’s only made possible by numerous manual procedures called ‘Analog modeling’.


The bottom of center section is lifted to take off unnecessary massiveness on the premise of adopting under diffuser that is the symbol and the pride of ground effect cars. State-of-the-art modeling is particularly noticeable at side section and this is what JNH represents.

   

GT3 Rear Bumper & Under Diffuser


Needless to say, the cooling duct is designed with high radiation performance and weight reduction in mind but the thing is in its manufacturing process. The designer’s free hand image of the parts is first converted to digital Bezier curve before it’s actually curved out as final products. Three-D carbon rear under diffuser, to work hand in hand with rear bumper, is designed to maximize downforce by adopting very high fins. This attention-to-details approach is our way to paying respects to RR cars.


It’s as easy as bolting on to the original wing stay. However, it’s nothing easy about designing JNH’s rear wing. We have worked diligently on the design of rear wing stay to create ‘Oneness’ with the approach area of the flap and this is what we are most proud of.


Owners can select material, FRP or Carbon, for this dual type flap which is very high in flexibility. Taking carbon for both flaps creates an aura of premium while the combination of carbon main flap with FRP sub flap adds some cutting edge flavor.


The sub flap is also adjustable so that owners can set up the best angle for various circuits. Even more, it can be taken off easily for top speed situation.

   

Sitting on both sides with huge presence is wing tip blades for which owners can also choose either FRP or carbon material.


Exhaust System


As contrary to being called ‘The racing car on the public road’, many owners are not satisfied with the exhaust sound of GT3. Owners can enjoy racing taste to some extent even in its original style but we took it further to be in the school of GT1 sound, to free up the engine and to find the ‘natural exhaust sound’.


Through all the experiments and struggles, we now deliver the ‘ultimate exhaust sound’ with the best combination of sound quality and volume achieved at the highest level.    


GT3 Exhaust System


Of particular note is the automatic switch-over system which changes from circuit mode (loud) to public sound (silent ? identical level as original exhaust system) mode with only a push of button. This enables owners to reduce the stress often caused by changing exhaust system ? starting engine in the wee hours of morning, warm-up operation in suburbs and parking at home in the midnight just to name a few.


Ultimate efficiency of engine exhaust


Our development staff takes pride in being a professional group in terms of the complete knowledge of engine and exhaust system. Furious sound volume and beautiful dry tone often attracts the attention but, as the data of Chassis Dynamo shows, the most important element of exhaust system is obviously exhaust efficiency. Needless to say, the high performance of muffler itself is assured and when it’s combined with exhaust manifold, they improve the efficiency dramatically yet still ensure enough road clearance. (Each parts can be attached separately.)


When faced with the reality of daily driving, the exhaust sound can become a headache for owners when considering the change of system. To solve the issue, this product comes equipped with switch-over exhaust system. By pressing a button at cockpit, the actuator controls the open / close of bulb, enabling owners to choose between circuit / public mode. (The level of exhaust sound in public mode is approximately the same as the original one.) You can go wild & loud or keep it smooth & low, it’s now totally up to you. This is for the owners who hesitated the change.

           

No less beautiful than Ferrari


Exhaust system can sing beautiful soprano when exhaust efficiency is at the highest. ‘Rough and Bass’ would be the words to express the sound of normal Porsche whereas this product will have you hooked on a high pitch sound. The exhaust note that complex R-form pipe creates sure compares favorably with the one of Ferrari.          


This four-tail-pipe is adopted to perfectly match rear bumper and rear under diffuser. Our unique system has two outside pipes used for straight exhausting in circuit mode while two other inside ones are used in public mode. Owners can also choose the material in either Titanium or Stainless.

           

Experience the sound of Racing Porsche


So powerful and rumbling is the exhaust sound of Racing Porsche on the circuit, this product enables GT3 to recapture ‘THE’ sound. The rejuvenated car sure reminds you of the classic ancestry of Porsche.


Side Mirror


This side mirror is designed to reduce air resistance coefficient and to maximize the visibility. Upon first look, it might be regarded as conventional design, however, the silhouette perfectly matches with the elegant line that extends from bonnet and fender. This is evident when looking from the front side.

   

GT3 Side Mirror


There are two types of material for this product, one is FRP and the other is Carbon/FRP hybrid. The latter is molded and done with FRP clear gelcoat finish except the surface is carbon. It often happens with wet carbon molding that resin does not reach the corners and edges, making the color clouded and fold line decrepit. As we want our products to be treasured for long time and as a countermeasure to aged deterioration, Carbon/FRP hybrid is adopted.
