Hi Lizard, how's it going? Got the new suspension dialed in yet?

I was wondering if anyone here has some recommendations for diff fluids for on-road speeders. I read on-road racers typically use heavy or locked front diff and around 10k cSt rear diff. I'm working on an Inferno GT2, 5682 motor, center spool, RTR weight will be about 4.5 kg, geared for 90 mph and up (depending on what motor will be happy to pull for continuous use). I'll be running 2° rear toe (instead of stock 3°), as Mike suggested below, to free up some speed, but have no idea if I should compensate that with a bit of a lighter rear diff fluid in order not to lose too much rear end stability. Any ideas?

What would be a good starting point for rear and front diff fluid, yielding good balance between straight line stability and handling (I'm not talking about serious track use, I just don't want it to be a straight line speed runner only that does not turn well)?
