Don't forget to adjust your CG calculations, if needed. Your good judgement required here.

It's easy to end up with a tail heavy RV-4 if you've got a light engine and prop up front.

Just saying.

I was very careful to adjust the datum point after the roll bar was moved back.

Ours is completely stock and I am 6'4".

I simply remove the cushion behind my back when I am flying. No problems whatsoever, and surprisingly comfortable, considering I'm leaving that seat cushion in the hangar...

I also highly recommend getting a canopy from Todd's Canopies (if it is not too late). Better canopy overall and it will provide an extra 2-4 inches of vertical sitting height for you, as their canopy is molded a little differently.

I'm only 5'10" but using Todd's canopy allowed me to raise my seat height (using Oregon Aero foam) about 2" higher than where I'd sit with a normal Van's canopy. I flew my friends RV-4 the other day and I felt like I was sitting very low and still did not have much room between the top of my headset and the canopy.

The -4 I just build has everything pushed around to fit me at 6-4 with a back parachute comfortably and still allow me to fly inverted and not hit the canopy. PM me if you want to talk.

Default Seat back

I curved the seat back. That was as tremendous improvement for me. I'm about 6'2".
