There will be non armed races too? 
Aw damn son. Can I have 2 cars maybe? I can say the Masked stole another car from the old gang lolz
How many non armed races were you thinking of? Cause, you know, good grip is the only thing holding some of our rides in the race when it comes to NOT shooting enemies.
Maybe we could improve our non armed stats by taking the weapons and armor plates off our vehicles? Sounds like a reasonable exchnage for like 5-10 extra points of stats for race oriented abilities.
But w/e you are the GM, its your shot
