Minimum possible then your in the wrong place and even the wrong sport.
I think you may be taking that out of context.
What I initially said was " My plan is get it running and race ready, legal, safe cost consciously."
Is the stock 820 transmission is unsafe, do I need a 700 with EC rear axle, EC clutch and EC front end etc... to be safe?
Can I do everything but the transmission and axle and save that for a later time and still be safe?
I want to do it right the first time, just not all at once, if I don't have to.
BTW, Your build blog is great, thank you for sharing.
