The swirl wheels have zero offset meaning the distance from the centre of the wheel to the face of the bolting plate is zero. This set introduced the driving ring extension and continued to use the Technic 16 tooth gear with clutch with teeth for half bushes.

While Technic vehicles tend to be built with left hand steering, due to Denmark following European standards and driving on the right hand side of the road, it is relatively easy to modify your build to make the vehicle right hand steering, should you want to. Inside the instructions shows how the first five parts-boxes are needed to build the chassis; these are the five boxes in the left window of the protective cover mentioned above. These eight parts-boxes are held in place with a cardboard sheet with three clear plastic windows. The window to the left shows the first five boxes, the window in the middle shows the last three boxes. On the right is a window which holds the four swirl wheels and low profile tyres. Super Street Sensation is one of my favourite Technic sets. I received this set as a gift in 2001 when my, then, six year old son was really into Slizers and Robo-riders. For me, it was a period of slightly-grey dark ages.The reverse of the flyer has images for Technic sets released in 1998; 8417 and 8428, and 1999 releases 8444, 8445, and 8446. On the inside of the lid there are several images showing how the gull-wings-doors and convertible roof operate. Smaller images show the chassis, which is the basis of the secondary models, the gear box and other engineering features. Holding all the boxes and wheels in place is a yellow tray. While not as effective as a sorting tray found in earlier Technic sets, it is still useful as a place to deposit parts during each modular building stage. The 12-tooth and 20-tooth double bevelled gears as well as the 20-tooth single bevelled gear (seen under the differential) were introduced in 1999.

Only the convertible and wing-door models have complete instructions: the other four models have partial instructions and some concept drawings. Above the four concept cars is a character using a light bulb to think about the necessary steps to complete these four builds. The sheer number of inspiration models in this set surprises me. I'm really not a big fan of the gappiness of this era of sets, nor of those old panels with the specialized ridges and grooves for tubing. I prefer the cleaner and more solid look of modern Technic sets.

Colour summary

The box itself seems more substantially built than the boxes found in today's larger flagship sets. The red 2M friction pins with cross hole are used to connect various modular components during the build. The main image on the front of the box shows the convertible version of the Super Street Sensation on a test road in a wind tunnel. There is also a smaller image showing the alternate gull-wing-door version of the car. The effect of all this geometry is that these wheels have a positive scrub radius of half a stud (4mm); the wheels pivot half a stud from the centre of the tyres. This gives 8448 Super Street Sensation the most accurate steering geometry of all Technic sets. Light Bluish Gray Electric 9V Battery Box 4 x 11 x 7 PF with Orange Switch and Dark Bluish Gray Covers
