Now you’ve got your buggy, what’s next?
After going over every inch of the buggy in your garage adding fluids, tightening bolts, zip tying loose wires (wiping the Jizz stains off it… you’re ready to take her out.
The absolute best bang for your buck tune up is tire air pressure adjustment. Air pressure for paddle tires / fronts preference varies widely with those who love to slide (drift) versus those who want to “stick” to the sand.
A good starting point is 11lbs of air all the way around then adjust from there. Over simplified being the more air you take out of the front the more precise (grab) the steering will be. The more you add in the rear the less traction you’ll have.
My tire pressure varied from buggy to buggy I’ve owned, My SU (4 seat V8) had 8lbs up front and 17lbs in the back (I love to plant the front end and slide the back around without using a turning brake).
Tuning air pressure is best done by establishing a track and running it repeatedly at your speed driving the way you like versus adjusting based on rides with others in the line up.
If you do power steering seriously consider EPS ( Electric Power Steering).
If your buggy is running great and you have a few dollars to throw at it the money would be better spent on having your suspension tuned instead of trying to make your motor faster.
