So basically, the Product Information PDF says that its 55/45 but in actuality, for the LSD RC F, its the 54.6/45.4 weight ration. Could be rounded up either way

The cars weigh differently in real life when they have all of the fluids, optional equipment etc. on them. Just quoting the tested weight distribution has been 54/46 (LSD) and 53/47 (TVD) in instrument tests. I am talking about the M4 vs RCF MT did back in 2015 where M4 was 52/48 and RCF (LSD) was 54/46.

Aight, makes sense to me.

Don't mean to sort of revive an old thread, but what was mean't when the brochure said the 'brake actuator' was changed? Was it the actual actuator itself that changed or was it just the actuating time/coding that changed?

Not sure, to be honest.

When looking at real life pictures, it doesn't appear like the brake actuator changed physically from 2015-2020, unlike the IS F's brake actuator change from 2008-10 to 2011-14

oh, and about the extra 5 horsepower that was gained. I read it had to do with the intake routing, they changed the intake air route or something and apparently it gets more horsepower. Not sure on the details though.

That sounds about right.

Found something very interesting regarding the brake actuators. Take a look at this screenshot:

This is on the lexuspartsnow website. Now, take a look at the production dates. It appears they discontinued both ones that were made for the 2018-2019 models, same for the 2015-2016 models, but not the 2017 models. Now, take a look at this screenshot from the official Lexus parts website:

Notice, on the Lexus parts website, it says it fits every model year between 2016 and 2019 (confused as to why 2015 and 2020 aren't included ). Is this simply an error? The only logical explanation that I have for the 2015 model year not being included is that in 2016, they changed the master warning light, which may make sense as to why the 2015 model year is not included. That sort of change would be more electrical, not really a change to the brake actuator itself. But, like I said, this could be an error!
