Test and Reviews

RC8 PRO TEAM

King Headz USA started a few years back with manufacturing cooling heads for 3.5 ccm model car engines.
Klick here for a review.
But soon Jim Walker president of King Headz USA was asked to make plastic parts that look to be fragile on some cars into aluminum.
This has resulted in many nice looking hop ups.
The house color for the parts is Black with a Silver edge.

For the RC8 review we received the full hop up package available from King Headz.
While looking through the parts we see the dedication and craftsmanship King Headz is putting in the products.
If the hop up is merely for the bling bling only then it is worth to use them any way.
But many parts are purposely machined to enhance the original RC8 parts.
Does this make the RC8 original parts bad? NO not at all.
But sometimes small details are worth to be used to make life easier or to take that 0.1 sec of your lap time.
In some cases it is the assurance to have some more durability when you abuse the car.

All parts are machined from billet T6-7075 aluminum and black anodized.

Our test driver Mark van Waaijenburg will give his comments on the King Headz parts and why he uses them over the original RC8 parts.
The info will be placed in his performance item.

	All the 14 parts that are available by King Headz for the RC8.
	The parts are nicely packed and labeled. All packages have a free King Headz decal for your cars body or other places.
	Where needed there is a small manual how to use the parts. Small parts like screws and nuts are always packed separately.
	RC8-040 Front shock stay Weight: 22.65 grams
	RC8-080 Front A hinge pin holder with the longer screws that are needed. The original plastic bushings fit. Weight: 5.09 grams
	RC8-000 Front B hinge pin holder with the longer screws that are needed. The hinge pin is now locked fully. Weight: 6.2 grams
	RC8-005 The Ackerman plate. Weight: 7.18 grams
	RC8-055 The turn knuckles are a piece of art and as expected machined from T6-7075 aluminum. The triangle hole to adapt the small steel bushings are there too. The original bearings can be used. The KHZ logo is printed on the knuckles. Weight: 13.76 grams each
	RC8-095 The servo saver poles. These are very, very light weight. Weight: 2.30 grams (each)
	RC8-010 The servo saver top plate. The original plastic bushings fit. Weight: 14.1 grams
	RC8-060 The front chassis stiffener. Weight: 8.79 grams
	RC8-025 The center differential top plate come with 2  bearings. You loose the free floating locker bushings to prevent brakes to be engaged while throttling. Weight: 6.25 grams (without bearings)
	RC8-015 The 2 piece EZ extended exchange motor mount. This one is specially made for Nova Rossi based engines. A version for Ninja based engines is available too as RC-015NJ. Due to the extension there is less flex around the clutch bell area. We had one wrong screw in the package. The screw for the 5 hole was not countersunk. Also the 3 mm lock nut was not in the package. The 2 piece EZ motor mount is fixed to the chassis by using 4 mm lock nuts, which can be replaced when worn out. No more need to use thread lock or damaging the head of the screws securing them. Mounting the aluminum engine bars to the main frame uses spring washers. Would have been nice if 4 extra 3 mm spring washers were added for mounting the engine to the two bars so no thread lock is needed at all. The manual clearly describes how to add the 5th hole to the chassis for the additional strength around the clutch bell area. Weight: 28.7grams (Base), 14grams (Top Blocks)
	RC8-070 Rear chassis stiffener. Weight: 11.55 grams
	RC8-050 The rear shock stay Weight: 30.47 grams
	RC8-090 Rear C hinge pin holder with the longer screws that are needed. The original plastic bushings fit. Weight: 6.75 grams
	RC8020X4 The D hinge pins holder in different values ranging from 2 to 3  degrees. The hinge pin is now locked fully. These are also available separate. Weight: 8.44 grams (each)

Hi,

Before we started driving with the RC8 we tested the King Headz parts we got and compared them weight wise.
This is the result:

So if you hop up the car fully with King Headz parts you still are on the same weight as with the original car.

	The parts we received were machined to very high standards. The silver edge and the black anodizing are a nice trim to the original RC8 color. For some it will be purely a piece of mind to mount one of them to be sure to finish a race. Some will purely add it for the bling bling factor. In either way King Headz has succeed to deliver high standard products.
