I had a bunch of different Redline fluids as well as ATS brake fluids and sold them all and went with the 300 as seems to be the best there is for this application and Rodmoe was really happy with it.
I went with Castrol SRF brake fluid, $$$, as it is the best and I use my brakes hard and had not yet installed brake ducts. I heated up the brakes enough to smell them at the end of some straights but always had solid brakes, it was a wise choice. Many race teams use it a whole season, in the end it is not that expensive since lasts longer that the others quite often.
The shifting was super smooth, accurate, LSD worked amazingly well with it.....
I am using the stock type engine oil for now but will switch to the German Castrol when I go full synthetic and might just use the blend one on the next change as well.
I think after the pounding my engine took at the track, 150 minutes worth of full throttle and full brakes, more on the throttle of course, hit the rev limited a few times, etc.....downshifted a bit early, I need to hear the exhaust a bit more so i can be more accurate.......it might be broken in as much as it is going to get. Next time I will have my three stage programmable shift light shinning in my eyes so I can do a better job in this department, I cannot read the tach well with my glasses on.
Anyway, if you use a car hard, I believe in running the best fluids you can afford and change them when you should.
I also will install a much bigger oil filter when I figure out how to get the stock oil/water cooler off and mount the Mocal Tstat plate and have room for a bigger filter. I use the Wix filters, great quality and value.
