How to read these results
In the original 100 ft race the Infraction Grom ran 2.49 s and the Mojave Grom 2.68 s. Neither car's configuration has been confirmed as stock yet, so this is shown as an original race result, not a stock test. Neither car is stock-tested yet.
All times are owner-reported. They are not independently GPS-verified, and the race date, surface and conditions have not been published yet.
Later runs with modified vehicles are filed separately as modified Lab records and say nothing about stock performance.

Highlighted rows differ. Unknown means we haven't verified the value — it is never counted as a difference. Price/performance can only be judged once both a sourced price and a measured result exist for every car; measured results from different configurations are not like-for-like.
Which one fits you?
Mojave Grom
Listed as a 1/16 desert truck. Desert-truck styling generally suits loose dirt, grass and gravel more than smooth pavement.
Infraction Grom
Listed as a 1/12 all-road street bash, rated up to 3S. Street-bash cars are generally aimed at pavement and car parks. It was quicker in the original race.
Prices and manufacturer speed claims aren't verified yet, so we can't make a value call. We'll update this page when they are.
