'11 Supra Launch 21v - how high does garage door need to be?

My '11 Launch 21v is coming in the next few days so now I need to widen (and possibly heighten) my garage door. Current door is a typical 8' wide x 7' high. I've confirmed that going to 9' wide will be sufficient, but my question is on the required height.

The supra has the progressive tower. Can anyone with knowledge of this boat give me the dimension from the ground to the top of the highest point of the tower when in the folded down position? The seller said it's about 7'-3" to the high point which is the tower hinge point. Just wanting someone that knows to either confirm or deny this before I go ahead and make my garage door opening higher than 7'

If it was me - I would measure the boat in question for myself.
I can tell you that it is higher than 7 ft and that you should measure the trailer width at the guide poles.
Measure the opening on your garage also. The numbers you gave are nominal - not actual.
Don't trust very close important measurements to someone 500 miles away for you.

Sorry I have been on vacation or would have chimed in.
Does it have the Z5? Will you be folding it with the Z5 or taking it off?
If it has the Z5 and you want to fold it with the Z5 I would save some extra space, but this depends on how low you want the Z5 sitting on the downward bars. An 8' garage is definitely doable. I have done it with no issues or close calls.
I would probably do at least 9' wide though. 9' will do it but will not have much clearance on each side. Think about your boardracks and your guide poles. If you have the opportunity now, you might as well make it right.
Good luck. You will love the boat!!!
