We use Motul Gear 300 in the transmission, and Motul Gear 300LS in the differential. The Gear300LS has a friction modifier, and slightly changes the characteristic of the torsen, and is also usable in some clutch type diffs. However, if you want to safe a few bucks (~7), you can also use Gear300 in the diff.
These fluids are multiweight, but are slightly thicker, so please keep in mind the gears will feel notchy when it's cold, and you'll hear the LSD "locking up" when it's cool outside and the car is not warmed up (under 50F, and making a U-turn when the car is completely cold). The tradeoff is the fluid's ability to handle more heat and abuse without breaking down.
That being said, any high quality fluid will work, and you can't go wrong as long as you have something good. I'd recommend a full synthetic, and use the Motul stuff personally in my S2k.

No we do not. The oil does get hot, but the ECU will pull timing to preserve the engine. We do, in the long run, plan on getting an oil cooler setup, and will likely have something custom made. If demand is there, CSG may offer a kit.
We run Motul 300V oil, and seeing 270F has zero effect on the oil itself in terms of breaking down or losing ability to lubricate.

I could see an upgrade in break pads (SS lines installed), do you think a Koyo rad is money down the drain for track use, DD car? Would you prefer a different mod in about the same price range as the Koyo rad, exclude hp gains? Fluids are cheap so my objective is to keep hp the same but aid in cooling, breaking, and turning.
Thx!

How much experience do you have with a loose car? My "typical" advice for anyone who isn't comfortable with a floaty/drifty/"always wants to rotate" car is to have a slight amount of toe-in both front and rear. While this isn't 100% ideal for performance, you're sacrificing maybe 1% performance for a HUGE increase in stability, both highway and on track. 1/16" total toe-in front, and 1/16" to 1/8" total toe-in rear (depending on preference, try less first). That being said, I prefer the CSG BRZ to be at 0 toe front and rear.
Alignment is frequently used as a band-aid fix for handling/suspension/balance problems that are caused by other parts. Sways and tire pressures are also common bandaids.
Brakes and radiator is ALWAYS a great choice. The car runs hot from the factory, and keeping temps down will help EVERYTHING under the engine bay, not just the engine, last longer. SS lines are strictly a preference thing, but brake lines, IMO, are a wear and tear item that should be replaced regularly. You don't want to have a brake line fail on you, ever. I change brake lines on my S2k roughly every 20 track days, but on the BRZ, you can likely go longer, as the brakes don't get as hot.
CSG is working on a cooling solution that will be a direct drop-in replacement for the OEM radiator that is more efficient. As with all the products we offer, it will not be the cheapest on the market, but it certainly will be one of the best products you can buy.
We use Speigler brake lines on the CSG BRZ. I have used Stoptech and Endless lines on my S2k. The Endless and Speigler lines are similar in construction quality and type, and are superior to the Stoptechs IMO.
