I was competing down at Walesboro near Columbus In yesterday. There was a large 90 degree turn which I was taking in second gear, near the redline. After the big turn was a three cone slalom. As I came off the throttle and braked for the first slalom cone it felt like I ran over a shoe with the right front...thump... then the car snap spun and I went off course into the corn field on the left. It happened so fast I cannot tell you which direction I spun, let alone do any countersteering. Not knowing why I spun off I took the corner at slightly reduced speed next run and again felt the sensation of running over a shoe and an instant of instability but did not spin this time.
So I thought perhaps I was running the air pressure a bit too low and the tire somehow folded and lost grip so I added a pound and half air to the right side of the car. Apparently this helped because I did not have the trouble again.
Thoughts?
Recently when I had the car on jackstands I noticed a rattle on the right rear with the engine turning the wheels over while up in the air. It was on the right side only. There is no looseness in the wheel and it rattles under no other circumstances. So I suspect the CV or wheel bearing. I guess I'll just replace both.
Although I cannot see how it relates to the spin a rattle seems to need attention. Last time I ignored a rattle on my 85 Reynard (may it rest in peace) the wheel came off as the cv was actually in six pieces. The car ran and handled fine right up til the rotor center broke from the disc and the wheel came off.
I am thinking of Pegasus for the part. Other options?
