Has any one used this fluid in their coupe/sedan? Or should I just stick to something else?

I hear it makes you brake as fast as the GTR.

Search is your friend, we talk about the SS brake line and DOT4 brake fluid "upgrade." It helps prevent brake fade. It is better to upgrade to SS lines then to just swap fluid.

I accidentally put this in my smart car. I braked so hard I gave my wife whiplash.

is this to feel more GTR-ish?

All it is OEM dot 4 fluid. It's required in the GTR due to increased heat. It wouldn't be any different from using a different DOT 4 brake fluid.

Lol... no it was mainly just to compare other dot 4 fluids to this oem dot 4... thanks for the laugh though

Thanks shakuya88
