Depends on how you drive the car. Tires should be fine for street driving. Just be careful if performance tires haven't warmed up. I had some issues with RE-11s but the other tires I've used have been fine. I expect S-04s will not present any problems.
I don't have an oil cooler. I hit 220-240F temps on the gauge daily for years now. I get a little timing pulled in the summer now and again, but no limp mode or anything. Not having an oil cooler just keeps me from beating on it for any length of time. If I sat in bumper to bumper traffic more often or took it out for autox or track, the oil cooler would be a must. It will likely be my next major mod.
