^like i said, big willow is hard on left front tires, and you need a significant amount of static camber to help combat this

Will be going to streets of willow this saturday, never run this track so will be fun. I'm at almost 3K miles, and need to do an oil change before saturday. Thinking of going full synthetic 10w30 thoughts?

I have been running 5-30 DEXOS cert Mobil 1 oil in my Z06 and it hasn't blown up yet. From what I understand, that's what they run in them at Spring Mountain outside of Vegas year-round beating on the cars in 100* heat. Works fine. Should be able to find it anywhere almost.

There's no point raising the cold weight, it will just mean the oil is thicker on a cold start. If you are seeing high temperatures regularly then you could consider an oil with a higher hot weight, e.g. 5W40. The second weight is measured at 210F. The 5W30 is going to be at it's ideal weight at 210F where as 5W40 will need 230-240F to be in it's sweet spot, and you'd have more protection at 260F.

Didn't think the stock oil cooler would work well in track conditions...

I will have someone take a look at the stock system tomorrow, I will see how easy it will be to cap off the lines from and to the radiator and switch to either air cooled one.

Keep both if you can (if enough room). The water system is beneficial in helping the oil warm up faster.

Yeah it sucks that the little stock oil:water unit can't really be upgraded in any useful way without tossing it. You might still take a look at just stacking sandwich-plate adapters to add a smaller air cooler onto the water cooler (e.g. a 19-row Setrab), but there'd be concerns about the integrity of the double-stacked adapters maybe. Hard to say without having seen the water one up close on how everything fits together.

I will take some pictures tomorrow, car should be on a lift for oil change and brake pad changes to get ready for track for sat.

One thing one of my friends said, there are some VW and Audi that have similar water to water cooler, he said I might be able to find a bigger unit to replace the stock one but will need to research............

please keep us posted about what you find for an upgraded oil:water or "sandwiching" the oil:water with an air:oil cooler.

Ran out of time at the oil change place. But today at streets of willow, must have been 50-60 deg out max. I was pushing as hard as the car would let me, ran a best of 1:32.7 this was the first time out on this track, so over all I think I did great. Oil cooler not so much, anything under 8 laps or so is no issue, oil temp stays at 235-245. If I push to 11-12 laps then the oil temp shoots to 250, didn't reach 260.
I definitely will need something, weird thing is the coolant's temp never moved an inch....
