Did some top speed runs today and managed a best of 57.1mph. There's still a lot of tuning to be done and I'm very confidant 60mph is attainable. Today's setup consisted of:
Talon's in the back and Road Rage II in the front
Some may wonder about the odd tire choice, well 25/83 was the most aggressive gearing I had and wanted more, so I slapped on larger tires in the back. and 57.1MPH was the end result. The car was surprisingly planted, provided you didn't make sudden turns.
Additional steps I'll be taking for higher speed, is obviously taller gearing for one. Going to run Road Rage II tires all around to reduce rotational mass and just depend on my spur/pinion to get me the faster speeds. Will lower the car for better aero. I was actually set to my higher suspension settings and used two spacers in the rear to keep the large talons from rubbing. And I'll be removing the lead fishing weights from the front of the car.
I think the combo of taller gearing, reduced rotational mass, better aero and reduced weight should be enough to give me the additional 3mph I need to break 60. My buddy who was running a similar setup, but geared 23/83 topped out an an even 52mph.
Here's a short video of our runs.
