Driving review and comparison with the RC350 F-Sport:
Very positive review of the RCF Final Edition by a Japanese professional race car driver.
Being the owner of an IS350 F-Sport (which is quite similar to the RC350 F-Sport and shares the same suspension as the RC350 F-Sport), I agree with everything he said except the weight distribution. RCF weight distribution with LSD is the same as the RC350 F-Sport. 54% front and 46% rear. RCF has a stronger, more reinforced rear subframe plus LSD in the back, which negates the added weight if the bigger engine up front. The steering rack is different in the RCF than the IS350/RC350 as it is a damperless setup. It means, the response of the steering is more direct, but it results in steering feeling heavier. Also, bushings are a lot more stiffer in the RCF than the IS350/RC350 F-sport
