Hi all, just purchased an all stock 04 Z06 and couldnt be happier, little backgroound on me, Ive been a long time porsche and bmw owner, I instruct for both PCA and BMW in the southeast, 4 years club racing, decided to switch to the Z06 cause usually that was the only cars that would blow by me and just dont think there is a better car for the money. My uses for this car will be double duty 6-8 DE events maybe TT with NASA, however still streetable, so this brings me to a couple questions (I did search ) but value guys who track these cars opinion the most, Fluids rec. oil? and Trans? diff? also I do plan to do the better radiator and oil cooler. Any other suggestions would be much appreciated, My home tracks are cmp, vir, lowes, ratl.
Thanks in advance Jason

Welcome to the Forum I think you will find answers to most every question you might have from the knowledgable and helpful members. I would first read the stickys, such as this one: C5 Track Car \ HPDE Conversion: What I have learned! Members who have tracked these cars for years have pronounced the C5 Z06 motors "bullettproof" if used STOCK and unmodifired. Coolers and seat time are recommended. Best of luck, and please give us feedback whenever you have an issue and implement Forum input to resolve the issue

PM sent Jason.
Are you planning on CMP with NASA in Feb?

As for fluids, I use:
Oil = Mobile 1 15W-50 or 10W-40
Trans = Mobile 1 ATF
Diff = Mobile 1 LS 75W-90
PS = Redline

You'll find you will need an oil cooler to keep the oil below 300* if you run the car hard for a 20-25 minute session. GM swears those temps don't hurt the engine, but they promised the bondholders they would be repaid, too.

Most of us install either a stand alone oil cooler or radiator/oil cooler combo. Installing either instills a bit of peace of mind. Just one less thing to worry about while on track.

Welcome to the Vette world.

Fresh fluids all around, a stand alone air/air cooler will serve you best in the hot SE. You won't need trans or diff coolers unless your doing 4 hr enduros.

I run M1 in the engine, amsoil in the trans/diff. I got high trans temps warnings with royal purple in the trans, not sure what the reasoning would be why, but I switched after that.

Thank you so much guys as I learn about this car. Now that I finally own one I really wish I wouldnt have wasted so much time with the air cooled porsches and e36 m3s, dont get me wrong they were fun but this car really puts a smile on my face.
Again thanks for any and all advice.
