Differences between the base model and the Type SH.
 

7-01 base- 15.1-15.5
97-01 Type SH- 15.2-15.6
97-01 SS- 15.7-16.1

....depending on driver....

All have the same H22A engine. The base is the quickest since it weighs the least and puts the most power to the ground. The Type SH adds:
SH specific 16" wheels that are slighty heavier then the base wheels

Leather Shift Knob (with Black stitching)
Rear Spoiler with no center mounted third brake light in the interior
Body colored side sills and rear under panel
Sport Shift is not available on the Type SH
Interior Courtesy Door Lights
Different Suspension setup (different lower control arms as well as lower locating link)
Also the Type SH retails for around 2-3 grand more.

The SS or sportshift Prelude is the slowest stock because it weighs in more then the base and puts less power down to the wheels because automatics are less efficient then a standard manual. Also top speed is decreased because it has 4 gears instead of 5. 1-3 gears are very similar between the SS and 5 speed models since Honda chose real world acceleration over ultimate top speed. Other then the tranny it shares all the same features as the base Prelude.
