Did someone say torque? - ryan.allen - 02-19-2020 Hey all, So I figured it was about that time to do a little write up on the "new" toy. It's a 2003 Z06 in EB with just under 80k miles with a laundry list of modifications. I was lucky enough to find the original owner who built the car and since then sold it to two other before I got my hands on it. The car was built and driven in autocross and HPDE at Sebring, then the next owner had it up at NJMP, and finally I acquired it from the owner who was a regular at Watkins Glenn and TMP. Interestingly enough the car did one lap of america a year ago and survived without issue. The original Mod list from when I purchased the car:
Since then I have revised and fixed a lot of "less than satisfactory" modifications that were done to the car. Newly Added Modifications:
I'm sure I'm forgetting plenty but that's a decent start. I finally got around to where the car is ready to see some real track time and see what decides to try and break, so I am signed up for march madness at VIR. I already went through a complete autocross season to feel out the car but haven't been able to do any high speed testing. According to the previous owner the car pulls the same at 150 as it does at 70 so we shall see how that goes. I've linked the original build threads from the Sebring owner below if anyone is interested. The motor was built and spec'd by Jeremy Formato from FasterProms and is absolutely bonkers.

Sounds so good. Did someone say torque? - JPolen01 - 02-19-2020 You're pictures are borked it seems. Sounds like it will be an exciting car to own.

Hmm interesting, they come through fine on multiple desktops, but are very broken on mobile.

No they're broken on my desktop too, looks like they're linking to your gmail: "https://mail.google.com/mail/u/0?ui=2&ik=87b1a26598&attid=0.1&permmsgid=msg-a:r161689905644496735&th=1705df972639444c&view=fimg&sz=s0-l75-ft&attbid=ANGjdJ_Eti4fpLQ8wGafJ77RHRNJXxFemGI2jvaQv1bRUsiGQJ7_CXdIL9zusqJ2S38-WZMOPs2LJFYHEzshe2wyJ-UfP3X7bYT14wX_0fGkYzMzl33Oi-iaEG8gM0c&disp=emb&realattid=ii_k6tffj110" which means you'll seem them but not us.

Consider swapping stock seats back in for now, unless Corvettes have something special about them I'm not aware of.

The z06 halo bar is(from what I read) just as strong as a rollbar. The C5 structure basically has a rollbar built into it, there a big crossbar right behind the seats that ties driver side to passenger then the roof halo that crosses over. The most dangerous part of the car is the windshield and it collapsing but nothing other than a full cage would reinforce that area.(02-20-2020, 10:00 AM)ryan.allen Wrote:Fixed back seats, harnesses, and no roll bar [emoji27][emoji27][emoji27][emoji27](02-19-2020, 09:54 PM)Senor_Taylor Wrote:It had a 4-pt roll bar that I took out and sold(weight and the bar was a drag racing bar that had the shoulder bar at the completely wrong height for harness angles), and I put in a Brey Krause Harness bar.

I spent a lot of money on unnecessary parts on the camaro to find out later that the safer/better way was with another part that was slightly different. It's funny thinking back about how little research I did back then, but all about safety now and doing everything the right way now. Also why the leaky diff was pulled just to find a pile of metal sitting behind the axle seals, but hey a bullet proof transmission and differential are in now and should outlive my time with the car haha |
