Last events before the big show

The last two local events before Nationals were this weekend and it was also the first time I got to drive the car with the new 12.5" wide (vs the old 10.7" wide) front tires and the new adjustable and stiffer front sway bar. Saturday started out amazing with the car displaying a turn-in so precise, I thought I was driving a kart, not a car with giant front tires. This seemed to come at the expense of rear grip, however, with the back of the car being pretty lively. I stiffened the front sway bar and this cured the over steer but turn-in wasn't so amazing anymore. I had the quickest raw time but tipped over a cone. Here are some videos from Saturday:

Sunday started with lots of optimism, I was hoping to get Fastest Time of Day but it didn't happen. I switched back to the softer front bar setting and tried to tame the rear by lowering the roll center one inch. The car felt fine on my first run but when I came into the finish, I hit the brakes too hard, locking up the rears and spinning into a wall of cones. Sunday spin from side camera Sunday full run with spin-in car camera
After that I was nervous about going too fast into the 3 hard braking zones and would land up lifting early, costing tones of time. Sunday quickest run

Adjustable front sway bar

I have new, wider front tires for Nationals and to avoid the chance of oversteer, I needed to change the front sway bar. I had a non-adjustable one on there before and I wanted an adjustable one but buying a custom made bar was out of my budget right now. I had some Porsche 911 torsion bars kicking around and it occurred to me that I could maybe use one as a sway bar. The beauty of using the 911 torsion bar is that there are a wide variety of sizes available and any one of them will slide right in if I need to change the stiffness.

There is very little real estate around my front suspension to mount a sway bar so instead of going under it, I went over it. Finding a mounting location for the drop links proved difficult. I landed up using a longer bolt for the pushrod mount and sliding the drop link over it.

I attached the sway bar mount to the rad/fender mount and significantly stiffened it by adding the x-brace you see right behind the fan

I took the 911 bar ends and drilled them for a set screw then welded a 1/2" thick bar to them, with holes for mounting the drop links

I painted the arms pink so they would be easily spotted
