A good weekend at Thunderhill...
Had a blast with CRT, a lot of other good folks, and the good weather at Thunderhill. We were running the 5-Mile circuit with Hooked On Driving.
Had my ups and had my downs. Dinged my front splitter in a brain-fade moment at the cross-over. I decided I shouldn't be on the track if I was going to let that mistake bother me; two offs now in 25 years is a pretty decent record. Decided on an alternative strategy. Found a guy in a prepped M3 who was running a pace similar to mine, but who clearly knew the correct line. I followed him for a session or two, which really helped. This was my second time at T'hill so it's still new to me. I then spent most of Saturday chasing a guy in his gorgeous new Z06/7, a.k.a. Superman. He's still getting up to speed, but could NOT believe I could keep up with him in my Z/28. On our last run he gapped me at the start -- I think the Trofeo Rs take longer to warm up than the Pilot Sport Cup 2s -- but then I started reeling him in. My best lap was a 3:43.77 -- and this was during my last run of the weekend. Given that our fastest laps were typically before lunchtime, because of track temps, I felt great about that. My new goal is to break 3:40, and I think that's realistic. Time to get some coaching and make it happen! Two observations: 1. The best thing you can do to your Camaro is to install the Brey-Krause harness bar and appropriate harnesses. 2. The second-best thing you can do is to install a proper racing shell. Now that I'm not flying around the car, under cornering and braking, I need to fix the headroom problem. Specifically, my head never moves as it's firmly jammed into the headliner. I'm so far back and up high that my sight-lines are terrible -- I need to be down as low as possible in the car. I'm working hard to find a shell that fits, and will install either a Sparco EVO II, Sparco ERGO, or Racetech seat. Racetech will make a custom shell for me for a $500 up-charge, which is a pretty great deal IMHO. None of the other makers (Recaro, Sparco, etc.) offer this service that I know of...

I have a Egro and am having fitment problems with it..even with sparco sliders..to tall and sits a little to upright.
I will have to mount it in a fixed position for it to work Maybe a Evo or Racetech would be better. |

If you bought the Large then I should be good; I have the HD Aluminum side-mount seat rails to use for the mounting. The height of the Ergo L is just over 40-inches; this is over 4-inches taller than the EVO II. That, along with the width at the top of the seat, make it a tough install in our cars...

Question for you since you tracked this car. I've tracked my E46 M3 that I used to have, and my C6 ZO6, that I used to have..lol..did you have to replace your brake lines for some braided steel ones? I did it on my previous cars, and I know they said the Z/28 is good out of the box, but im asking you since you were there on the track, how did the brakes feel throughout your session. Were they fading or were they good till the last hard drop. If you did replace them, which brand is best for our track monster?

The brakes on this car are killer, and I've changed nothing. You shouldn't go to braided SS lines unless you want to replace the lines every two years. I'm no expert, but I was told by a race shop to keep the standard lines, as you can more easily target a problem if there's any cracking or issues with the lines...

A grab of the B-K site showing the harness bar; the reason I like this bar is that B-K makes the highest quality and best-engineered products on the market. This thing installs perfectly with no cutting or trimming required. Simple, beautifully made, and very strong:

I have nippers that go in the back seats so this is appealing to me if it comes in and out easily. According to the pdf you leave the brackets on the backseats in. Are they flush or would they push against a nipper under normal driving? I would be interested in your observations and still send a pic when you can.
thanks

Hey, sounds like you are really enjoying the Z!! Few questions:
What tires are you running at the track? Are you driving the car to the track as well? That oil temps are you seeing? Thanks Frank Red Z28 |

What tires are you running at the track? Pirelli Trofeo R OEM tires. I have 8 track days on this set and expect to get at least 10, maybe 12 total, before needing to change them out. Are you driving the car to the track as well? Yes; it's a 2-hour drive from my house to Thunderhill What oil temps are you seeing? During this event the highest temp I saw was 260 degrees. The ambient temps peaked at 75 to 79 degrees.

UPDATE: I found an Ergo/Large at a local shop. They sold it to me on the provision that I can return it for a refund if it doesn't fit in the car. More to come...
BTW, I'm 6'7" and 235 pounds, with slightly more length in my torso. The ERGO-L fits me like it was made for me, so I'm really hoping it squeezed into the Z/28. It is a MUCH better fit than the EVO II; I could fit in the EVO II but it was a little too short and a touch too tight in spots.
