totally depends on the track and your driving style. id say a majority of US tracks can get a little bumpy and have larger jumps so you want a higher ride height. I set mine up with the back higher than the front so that entering a corner off power I get a bit more bite (front end) from weight transfer to the front. i think im at 29/24 right now which is a bit extreme and sometimes causes the buggy to slightly nose dive over larger jumps but thats easily correctable with the throttle.
set it up front higher than rear and youll have more rear on power traction cuz weight will transfer to the rear.
super smooth tracks w smaller jumps = lower ride height
