69 front sub frame alignment
« on: July 21, 2011, 04:54:54 AM »
car in question is to be set up for nhra stock eliminator racing only. can i install the front sub frame at a slight angle to give me a staggerd wheel base for better roll out without ending up with "dogtracking"? i think i can get 109 inch pass side and 107.5 inch  driver side wheel base .

Will you be able to get the sheet metal to even come close to alignment? It maybe easy to do it with caster adjustment although I don't know how much you can get out of it. The torque push may keep it from doglegging it is offset correctly but it may still pull bad on the big end, especially on decel. Just a thought.

If all the bolts are loose the subframe can "float" around. The sheetmetal is anchored at the firewall and radiator support. The subframes were installed under an assembled body per the CRG assembly report. The inner fender to frame brackets must be loose also. Steering column alignment could be a problem if too far off.
