Autocar Dry Handling Track - ISF - 1:16.90 RCF - 1:15.10
Autocar Dry Handling Track - ISF - 1:16.90 RCF - 1:15.10
Edit: I looked at the site/times and it's obviously based 100% on driver submissions. They have a some high performance cars in that list running 1:30 times. That could be the point he is making when trying to compare cars based on findings on the internet...

On what planet does the wet time drop 9 seconds below dry time on a 1 minute track?

The Lightning Lap is the same drivers on the same course over the same few days. It's hard to get a more even comparison than this. Everything you have posted above is no different from Drag Times - different drivers, different weather, with only one constant - the physical location of the venue. And as was previously mentioned, the '11 IS F ran a slower track than the RC F and GS F. Besides, these two should have slaughtered the IS F's time. They didn't. IMHO, Lexus failed miserably to push the envelope forward with the RC F and GS F. Don't get me wrong, I really enjoy my GS F. But my IS F is way more fun to drive, and I am confident if I went to an HPDE I would be far more concerned about keeping up with a well driven RC F than I would about just the car.
I understand and agree a 100% that the site I posted was no different than DragTimes hence "If dragtimes website are used, then we should look at the site below." on my post yesterday.
Now that I've cleared that out, this is a forum and I love having debates and fun conversations. I learn a lot about things by engaging myself into car forums. However, I can tell that the whole RCF, ISF, GSF comparison has become a bit of a touchy subject across the board. I really don't have any issues with the RCF not being significantly faster than an ISF. If I wanted a car that was significantly faster than an ISF, I would probably have gotten a different car. At the end of the day, from the day my best friend got his 2009 ISF (brand new in 2009), I've been a fan. Most of the F owners I hangout with in Houston are all ISF owners. I really don't need "inner peace", at the end of the day, I could have gotten an ISF if I wanted to. I chose the RCF for personal preferences.

Exactly IMCHIA we hang out with lots of RCF owners here in Socal also and hanging out and chilling is the best part of our F ers group . We all choose what best suits are needs . Just Love what you drive .

Stock 1/4 times from Drag Times of ISF running 12.3's, 12.4's, 12,5's, 12.6's etc.

I don't think people have any incentive to lie, but it also depends on a variety of factors unrelated to the car, such as location, track, and driver. They're also posting timeslips and video, so I think people are generally transparent about this. Plus, a number of people posting times on there are also members of this board, where they used to participate in deeper discussion threads. It was friendly competition and very informative.
For example, take a look at the sticky thread at the top of the forum.
Official IS-F Drag Time/Dyno Time/Performance Thread
The fastest cars were running radials, but the trap speeds were indicative of stock power levels. Once the FBO cars come into play, that's when we saw the higher teens for traps, and this was all before the tune was available. I wouldn't suggest just anyone could go out there and post the faster numbers, but I also don't think people are just making things up.

Im famous!! Ive been posted about twice!
Those were some fun days, when the F felt fast AF and the sound of a nitrous V8 doing a 5 gear burnout, ill always miss. I suppose i could put nitrous on my '10 but its the famly car, lol. Look up my Nitrous 1/4 mile vid. My fav video to date.
I did a 12.8@111 stock on my '10 for reference. Prob could of shaved it down to a 12.6 if I stayed longer.

Regarding the times that you posted I found something interesting as well all the times that you posted were pre 2011 except for one prior to all updates in 2011.
Hockenheim Short was done with 2010 ISF 2.15.80
Hockenheim GP was done on 9.5.08 2008 ISF 2.04.45
Circuit de Nevers Magny-Cours done on 6.10.09 2010 ISF 1.28.10.
Now Sachsenring is interesting you posted the slower of two times listed, you posted the pre 2011 ISF of 1.42.11, the 2011 ISF posted time of 1.40.81 on 7.12.11 over 2sec faster then thec previous ISF. The RCF still put down faster time 1.39.53 but with the introduction of the updates in 2011 you see how much closer these two cars now become. On side note ISF had a faster time then E92 M3 which posted 1.40.90.
I still have hope for the F brands especially now that Lexus is finally racing in the GT class. The RCF is definitely holding its own and doing well in this class. The knowledge they will gain buy racing will hopefully filter down into future models Such as 2 gen RCF, GSF LCF perhaps even and ISF if they ever decide to bring it back.

I definitely appreciate the input not trying to again state that the ISF is better then the RCF just that these three cars are very close in performance numbers and that FBO ISF turns into car that can surpass its two siblings with decent investment.

If they had only kept the car at the same weight as the IS. There wouldn't be anything to discuss at all.

Dont forget the Tire tech has come along way since 2008 what was then available for Isf and what is now available for rcf is night and day. Pilot sport PS2 over PSS That's a big difference on the track . I would love to see what same tire size and brand does on the stock cars.

Could you imagine if Lexus would have dropping that same drivetrain blue top motor, TVD, track modes, better suspension with carbon fiber roof trunk and deck lid. Any other lightweight components on the ISF to keep its weight under 3800lbs, such as light weight seats, lighter weight chasis like on F80 M4. They would have ended up with beast, it would have shown up its siblings, possibly even LC 500. Lexus will probably not produce
ISF any time soon fearing it could quite possibly pull sales from its Bigger sibling. Much like Porsche not giving Cayman aka 718 now, the same power as its 911 brothers. You can't have your little brother 90k car out perform or match the performance of his 150k to 200k big brothers.
Only time will tell, may they drop the rumored twin turbo 6 from LS into ISF now that would be insane if that ever happened.

Couldn't agree with you more, the Achilles heel of RCF is its weight.I love the way it looks both exterior and interior N/A motor, better suspension, etc. But you can't hide that much weight with out having more hp, better suspension like GM's magnetic ride. Everyone understand weight is enemy of all performance vehicles.
