Streetability Index

How Streetable is Your Car?

Is your car streetable, or are you just a rolling “equipment violation ticket” waiting to happen? Go through the checklist and indicate how your “daily driver” is modified and let DSPORT‘s custom Streetability Algorithm tell you if you’re the king of the road or just another trailer queen.

The Streetability Index Explained


The streetability index (SI) number places survey takers into one of five categories.

The Completely Streetable category can encompass the widest array of vehicles ranging from bone-stock commuters to highly modified streetcars. The challenge for high-performing vehicles that land in this class is maintaining the same level of convenience, utility and comfort as the vehicle had before it was modified.

The Streetable section includes vehicles that have sacrificed some practicality but have preserved the ability to be driven on public roads. The followiing section, Slightly Streetable, encompasses vehicles that are entering the grey area of what is practical to be street driven. These vehicles likely operate on roads but are more suited for track use. Further compromise of streetability will push vehicles into the Barely Streetable category. These vehicles really shouldn't be driven on the street but are technically capable of it. Vehicles scoring in the Not Streetable category resemble racecars more than streetcars and are likely to be dedicated race vehicles.

What value does this number have? The value in the SI number can come when relative comparisons are made with the performance of the vehicle in mind. For instance, building a 10-second FWD or RWD vehicle with a streetability index of 90 presents much more of a challenge than building a 10-second all-wheel-drive vehicle with the same streetability index. Therefore, streetability can be thought of as a boundary in the quest for performance. If that boundary is crossed, it is typically associated with "race only" territory. It's important to note that this boundary is not static and changes over time. Some of the latest production sportscars could easily outperform racecars of the past.
