I'd just go all out with a 6 point cage... with all those events you plan on doing... forget about having this a daily driver...

autopower's u-weld front cage's door guards aren't that high... you can still get in and out using the door.

also... I hope you don't plan on succeeding on all those events with just one single car... certain suspension set-ups would contradict each other (i.e. ideal spring rates on drag cars as opposed to drifting)

i could use 20 diferent spring rates just for the local autox courses alone,so im not to worried about spring rates

this isnt a daily driver, its a street legal race car, a different car gets DD duty

my suspension will be designed with plenty of extra mounting holes, so the diffeences in suspension geometry for differnt aps will be mostly covered

and i was thinking id maybe want a slight bit more then 6 points .. considering the extent of the frame mods ill have ... maybe like a 10 or 12 point with more then just a single door bar... add in a dash bar, front and rear x braces ... that kinda thing ...

have one made. Pull out the regulatory guides for whatever events you plan on going to and go with the strictest set of rules and let the builder know what those guidelines are.
