Yes, understood.

I really hope Lexus keeps the NA V8 going in the F in the future. I like NA V8 versus FI whatever.

It goes to 7300 rpm stock? It seems like a typo.

Haha, LOL.

Really, Our RCF red lines at 7300 rpm and then the rev limiter kicks in and cut the engine off.

The reason why the RC F is so heavy is because they initially wanted to make a convertible version of the RC. That's why they used the ISC's middle section for structural rigidity. All that extra bracing would have been necessary. However, it looks like they decided kill off the convertible version of the RC back right as they debuted the LF-C2. It's really a tragedy because they made so many compromises to allow for a convertible version but they never did release a convertible version of the car. I'm sure the rigidity helps with the handling dynamics of the car but between rigidity or weight savings without the consideration of a convertible version, they probably would have opted for weight savings.

I can confirm this is true. My buddy works for Lexus and has said this is the exact reason it's so heavy.

Sorry if I yanked your chain... I wasn't sure as well but it's at 7300 rpm. I wonder how much it would be for the Tune...

Since the mid section has all the extra bracing for convertible, is there a way to modify the unnecessary bracing safely for non-convertible?

Maybe that is the LC500? Is the LC500 lighter?
