Then, the c5z06 overheats. I can't even HPDE it until I address that for oiling and transmission cooling.
Then, there are the breaking valve springs. My VIN is right in the middle of that.
So, I don't think the above is incorrect in any way. If you are looking to GO FAST and want power, I do think the C5Z06 is the right choice. However, brakes and tires are easily 2-3x more and you go through those consumables QUICK (ViR is my local track).
This is what I am struggling with. I don't hate the c5z06 at all. It is a great car. I just can't use it and can't commit to throwing down 2-3k just to get it ready to step onto VIR Full.
Thanks for your experience, however. It is what I am still mulling over.

Breaking valve springs is a cheap fix.... aftermarket beehives are 300 bucks? Replacement is easy and doesnt involve a car breaking recall.

take the excuse to throw a cam and upgraded timing chain in. Easy.
Mine never had overheating issues, but they are bottom feeders, keep the radiator clean and make sure the air dam is still there and most of the time it's not an issue. Radiator replacement is a cheap upgrade. Brakes are NOT expensive. The c5z brakes are nothing special and parts are readily available. Like I said, most running costs aside from tires are pretty comparable, but the base is much stronger with the c5.
You're going to run in to overheating issues tracking this car as well and an oil cooler is almost mandatory. It all boils down to what fits you as a driver, but it's good you're doing research.
