      Sorry that it didn’t go as well as you’d hoped it would. But… you got to drive your Comp Coupe at Kansas Speedway and considering all that happened, you did well. And you learned a few things which will help next time. When I read the title, I thought it might have been much worse! I glad that it wasn’t!

      Minor little problems are all part of the game. Good try on the splitter fix, 155mph probably trying to hold up 300-400lbs and some knarly harmonics going on. You didnt give up is all that matters some days

      Yep. Looking forward to giving it a go. Downside about something like this, most likely you won’t know if it’s good until you’re on track.

      I may sneak a spirited drive up the local highway in the early morning hours and see if I can feel any shudder.

      The first attempt was pretty weak. haha I’ll send you an email shortly with what my next attempt will look like.

      On a track like that you probably lost confidence in the splitter like that, hard to push the car hard when you’re worried about stuff like that!

      I’ll find the lap it broke and post up the video. The car was buffering so badly that it felt like I was hitting speed bumps at 120+mph.

      Lotus spins at 3:47, and my splitter supports fail at 5:11.

      Seeing this really makes me want to try out a track that is a roval. That looks awesome. I have to think those titanium sheets will help keep this from happening again, even with all that downforce pushing on them, they should be good.

      Yikes! Yeah you can’t drive with confidence with an issue like that. Hope you get back up and running soon.

      I love driving new tracks, the roval was not my favorite at all. I don’t mind some banking and stuff, and it definitely would’ve made a difference if I had adjusted my alignment better beforehand, but in the end, I prefer the longer road courses.

      Insane. I’m just glad it didn’t happen going around the corner. Haha

      This weekend I joined NASA Central at Kansas Speedway to run their ‘roval’ course (counter clockwise). The only variation from the below photo is they ran a make-shift bus stop on the back to slow people down. I’ve never quite seen a chicane as narrow or as short as this. It definitely served it’s purpose.

      Saturday morning, it rained from 6am-11am. I ran two sessions after noon and never really felt comfortable. The transition on the back after the chicane from the apron to the bank was so dramatic that my right rear tire hopped on the ground. I should have adjusted my alignment as my passenger front tire rubbed through my wheel well liner completely, and the rub strip on my splitter did it’s job, but sadly outstayed it’s welcome. The track was covered in gravel, I have several pounds of gravel that found it’s way into my car, AND my front bumper looks like it was peppered with a 10 gauge. Luckily, I have a Lexan windshield, or I would join the crew of cracked windshields.

      Sunday in the first session I bested my lap time from Saturday by 6 seconds, and cracked into the top 5 of the event, but also ran into some bad luck when my interior cable supports for my splitter pulled the bolts through carbon fiber on the splitter and destroyed one of the two brackets. My wife and I made a run to the hardware store for bolts, washers and something I could fashion into a bracket. About an hour of ‘mending’ it back together, I was hesitant to give it another go, but really wanted to jump up in the timing so I went back out. Made it around on the out lap with no problems, but once getting up to 155mph or so on the straight, they both failed again and I was forced to limp around with the splitter buffering the whole way.

      Today, I ordered a new support (one of the two broke), and 4 6×6 inch titanium sheets that I’ll use to reinforce above and below the splitter to prevent this from happening again. Good news is, while I was out there, I really enjoyed the canards and the taller wing, it’s amazing how much of a difference more aero makes.

      Ended the weekend with a 1:31.42 lap time, which isn’t very impressive. With a few more laps I was shooting for a 26 or 27. A friend of mine in a MY19 ZR1 took home the fastest lap of 1:25.63. I don’t think I could’ve outrun him as he had 10mph or so on me on the straight.

      Here’s a video of the fastest lap, tons of time left out there. I was frustrated when the car fell apart because I was just getting comfortable with the track.
