Had an incident in the last weekend of the season involving the front right corner. Light-medium contact (fender was barely rubbing on the tire). Nothing looks obviously bent, it might be alittle toed out, but that could be cause the fender's off. Other than trying to align it or checking the alignment (which I can't do at home), any way to check for damage?

Look for obviously recent cracked/peeled paint on the control arms. That's a sign the metal is deformed. Visually inspect right side vs. left side.

You can usually get away with "light-medium" contact without bending anything. These car are sturdy little beasts.

How did it drive after contact? If you were able to continue, how did your lap times compare, before vs. after? I sometimes run my fastest laps after contact - I seem to drive better when I'm pissed.

Undriveable after contact due to rear end damage.

I'll take some time to compare the r/l. Just wanted to change any bent parts before I sent it for an alignment (and then had to pay the shop to do it), but if I'm unable to tell . . .

Thanks.

just as counterpoint... i slid off turn 1 in the wet last year at VIR and just grazed the guardrail with the left front and the LCA was bent. i was unable to see where the bend was, but it was obviously tweaked based on the positive camber that wheel suddenly sprouted. if the hit was on the wheel, i wouldn't be surprised if a control arm was bent. if the hit really landed on the fender, you might be alright.

As you check your alignments, keep in mind that a rim could have also gotten bent in a crash. Another set of known straight rims would be useful or rotate them to see if alignments change by location.

My experience with "light" right front contact resulted in no appreciable change in handling and after the event a perfect alignment. Then I noticed that the RF wheel was about 3/4 inch closer to the rear fender well than the LF wheel. I changed the lower control arm and the gap was then equal.

Moral of this story. Used control arms are cheap, change them both on the corner hit.
