what class are you looing to run in.....?
that chassis pic would be good for most cars down to 8.50. Typical super gas 9.90 or super comp 8.90 would be ok. Bracket class down to 8.50
anything quicker would require a 25.5 spec chassis, lots more bars and funnycar cage. But 25.5 in mild steel... that all seems to be up in the air right now.
for super street or any 10.5 class, check with the lcoal rules about what you can use for the front end, and or stock floor and firewall stuff.
