I agree with this as well as the IS F looking better than the RC F Is it just me or does the RC look better than the RC F? Especially some of the modified ones I've seen lately.

Yea, I'm on the same boat. Even sold the ISF in anticipation of the RC-F and then ended up with something else altogether

I think you guys hit the nail in the head... you lose 2-doors, gain a bunch of weight, straight line is about the same, so I suppose you gain gadgets, handling, and easy-to-achieve lap times? I don't see the added value considering that we'd have to drop another 30-40k for it. And yes that's not factoring in the styling. I feel like if Lexus stuffed the V8 into the 3IS it'd be much better looking and we'd jump all over it.

Plus if you address the handling with some nice coilovers, add some suspension goodies from FIGS, throw in some headers and a good exhaust, lose some weight with carbon parts, you'll be way under the price of a new RC-F.

I'd also argue you would be quicker under most conditions due to the lower curb weight.

You also have 4 good sized seats, and a useful sized trunk.

Plus, how long will it be before you can buy any decent aftermarket goodies, and how much will you be paying?

I'll keep my IS-F thanks.

I could not have said this better myself. After reading through the New Car Features manual, there isn't a whole lot of special in the RC F to make it worth selling the car I own outright for one of nearly equal performance with less interior room and less overall utility. If they'd made it even the same weight as the IS F, they would have been way ahead, but their choice to make it as porky as they did immediately made me wary. The real shame is, had they built it at 3600 lbs, no one would be talking about the M4 even being a rival. It would smoke everything in the class, and even give me a couple of laps before I have to give a point by to the fast guy in a Corvette at an HPDE.

my friend who tested the RCF for Lexus during development said the RCF ride much better than the ISF and has more grip in the corners. He said the ride quality is a world better than the choppiness of the ISF . Luckily I live in AZ and dont care about ruff roads.....we dont have them

But again I'd mention things like FIGS suspension parts, additional bracing, LSD, KW coilovers.....

Add these to the ISF, and have the whole setup adjusted by the right shop, and the handling won't be far off the RCF.

You also have less weight to contend with, so performance and handling are easier to improve.

It's all a personal choice at the end of the day.

I personally wouldn't take the depreciation hit when you drive it off the forecourt, the greater weight, less space and practicality, and a knowledge you will lose a chunk of cash in the first years of ownership.

All for a car that doesn't set a new bar in comparison to the ISF, but comes in around the same numbers, with less practicality.

If I wanted two doors, I'd buy a GTR.

Throw on an exhaust and you've pretty much match the RC-F in the power department all while weighing hundreds of pounds less.

Which year of the IS F was he referring to? Personally, I don't find the IS F ride to be bad (mine is actually more "harsh" than stock), but it's also known that the later models were more compliant and handled better. Also, in terms of ride quality, I feel like the RC F is a car where you can afford to sacrifice that (if you had to choose), given it's less practical (overall) than the IS F.

I don't doubt that they've refined the RC F, and I'm all about feel, but did your friend comment on how the weight feels when driving? I've dropped some weight from my car, and while I probably won't be chasing down 911s, it feels noticeably nicer. On the other end of the spectrum, there are cars like the Model S, where they're heavy, but the weight is very low in the car, so it feels great.

Reading the articles, one significant negative indicator for me is the "laser welding/stitching" two cars together. The fact that this car wasn't drawn up from scratch seems lazy and lacks thought.

I think aesthetically it looks alright.

I can not blame them nor do I feel it was laziness. It was probably a significant cost savings, to not have to re-tool the entire production line (or outsource) for the shared components.

Lots of other manufacturers use glue/ epoxy these days on many critical structural areas.

He was a test driver for the ISF and the RCF ( a ton of other Toyota and Scions too ) during their development . He was talking about the early ISFs....most likely 08s. The issue with adding more power to the ISF is grip on launch. I have heard so many complain about spinning the tires off the line . Now that temps in AZ have dropped to 70s I am now noticing this. If my tires are cold I can spin the rears ( while still moving forward ) for about 1/2 to 1/3 of the way through the intersection. The ISF , like most performance cars, was designed with a balance. Adding power will upset the balance. If you add an exhaust you will need wider tires absoluetly.
