It does not matter. We know absolutely nothing about the Lems IS-F.

You are arguing about the wrong things. Unless the Lems IS-F above has immense number modifications, it is not getting anywhere near supercar-levels of performance.

Even Ken Gushi and the editors of Autoweek admitted IS-F CCS-R cannot come close to the LFA.

You don't shave off 10 - 15 seconds per lap off a lap around Fuji just by doing minor modifications. It just does not work that way.

"we "as in you im guessing. i know alot about the lems isf. its tuned, exhaust ,intake, suspension mods and weight reduction but nothing near how much weight reduction was done to the ccsr. autoweek? really? i take magazine opinions with a grain of salt. anyways like i stated early im not stating the isf is greater,faster,etc than an lfa. but the lems isf is lapping fuji faster than a stock lfa. lems isf is around 460 to the wheels.

460 wheel HP with intake/exhaust and tune so over 110 wheel HP more than stock with basic bolt ons?? OMG, this keeps getting better and better. Put it together with its back straight speed on FSW of only 250 km/h, it does not add up at all..

Anyway, I am done arguing this otherwise, it will kill more brain cells in my head. BTW, LFA did lap Fuji in 1:54 with Akira Iida in their option auto feature, but Lems is on racing tires, which makes a huge difference in cornering speeds especially on a very small track like FSW.

The Gazoo LFA with a de-tuned engine putting out only 490 PS, 3400 lbs weight and a 7500 rpm rev limiter (down from 9500 rpm) on full racing slick tires did a 1:47 around Fuji speedway in a best motoring feature.

I have yet to see any IS-F doing better than 8:18 on a power and very high speed and technical track like Nurburgring. Let alone, anywhere near the 7:14 Akira Iida pulled in the LFA.

IS-F CCS-R has a weight reduction of about 400 lbs and puts out 450 PS to the crank. Regarding CCS-R which this thread is about, I would trust the pedal-to-the-metal video, Ken Gushi, Scott Pruett's word over any other source anyday of the week.
