Weapon F

Don't know if anyone has seen this video but this is why I think many of us have kept our ISF. I'm not bashing RCF, I like they way it looks and tech I'm fan of car and was rooting for it to be beast but the weight of car especially being N/A in this forced induction world that we now live in along the Frankenstein nature of chassis didn't help it. GSF better sorted car but way down on power and now LC500 they seems to have gotten this car right except for once again the lack of power? 470hp, 3 more hours than RCF and GSF what is Lexus thinking. To keep it N/A they needed to increase displacement from 5.0 to 5.7 or better with weight of over 4000lbs. Once again Lexus being ultra conservative. They have winner with LC500 but it needs some sort of forced injection if they truly want to compete in current world market especially with 100k price tag. It hard to believe that 9yr old ISF with some simple bolt on mods and tune through in some suspension tweaks and good set of tire and your competitive with one of them and out performing 2 of them, add in RR Racing SC and it's game over for all 3.

Seems about right as being lighter has it's advantage plus with headers and exhaust, the ISF is making nearly as much as the stock RCF. That seems like a good run though - the ISF driver mentioned didn't beat it by much. Add an exhaust to the RCF and it'll be a driver's race.

ISF had a passenger as well. The weight difference was negated.

people wanting an ISF in a nice 2 door coupe, the rcf is there to fill the void since 2015. RCF has a quieter cabin by far, better interior and gadgets, better audio, nicer engine bay. if you are only into speed, maybe sure , you'll be happy in the ISF. I don't think many will know how much better the RCF is until it gets cheaper to attain for them. Reminds me of the M3 forum every time a newer model comes out.

ill also leave this here.

To be fair, we also don't know if the RCF had a passenger.

I'm not here to start ISF vs RCF debate because that debate always occurs. I'm just saying I've raced more than my fair share of ISFs, so I know exactly how a stock RCF compares and how a RCF with exhaust compares. I've raced couple full bolt on ISFs numerous of times (Intake/Headers/Exhaust/Tune) and my RCF with exhaust is head to head with them.

Yup, I've seen your video with RCF500. Can't really explain it why the results are different with my cars vs FBO ISFs. I also have numerous of videos myself of me vs FBO ISFs. That video is me vs 2 FBO ISFs (you can barely hear the honk but it's definitely there).
My best friend has an ISF and this is how we compared:

Stock RCF vs ISF with Exhaust and Intake - We were even each and every match (we've done over 30 runs). With maybe a slight advantage for the ISF as I weigh an additional 90 lbs more than he does.
Stock RCF vs ISF (Intake/Exhaust/Headers) - No competition. ISF Clearly faster.
RCF with Exhaust vs ISF (Intake/Exhaust/Headers/Tune) - Very close - driver race.

They're probably thinking they're going to save something for the LC F.

That first video made me cringe. Reason I have the IS-F is I need 4 doors for my family. No way I'd want the RC-F with a family. Maybe when the kids get older I wouldn't mind getting into an RC-F

try racing one with 19 inch wheels, I'm positive the outcome would be better for the rc-f. i know for a fact, if you slap 20s , even lightweight, on the ISF, it turns into a slow car.

I would luv to see LCF, perhaps Toyota and BMW new partnership building new Supra and Z4 platform they get some BMW experience with high performance turbo Tech. That's what LCF would need in order to stay competitive.

"I'll also leave this here" Haha
10-4 on the M3 forum! Those debates rage for years. RCFs are badass cars and faster than ours out of the box. ALL RCs have a nicer, newer interior over ours. 100 fold. People rag on their weight and chassis design... I thumbs up every time I see one. Just brothers in the same club.

Not to detract from your thread too much, but Toyota has filed the trademark.
