8100-8200 Redline (This is a safe/conservative redline for a k24a2 with type S pump and 50 degree vtc from everything I have read but I could be wrong!!)
This gives me 59.9-60.64 mph top speed in 2nd gear at redline so seems like the 4.56 is absolutely perfect.

Of course the other option I am considering is the 4.3 from a 2017+ which would save me a lot of hassle of figuring out the best 4.56 gear package to select.

Either way I want to do gears 100% as I will be getting an OS Giken Super Loc LSD installed at the same time.

I'll probably wait to mess with gearing ratios, but wanted to know now that it's been mentioned what is considered a safe redline with the RSX oil pump? I was under the assumption 8500 was a safe spot, but you saying below that makes me question what I've read up until now.
