    I'd assume the race info says "better MRA/Lower Mass" so he thought to post here.

    The 24 actually has more MRA and power than the other 2. Weight is similar too when the cars are stock,but the 24 is a one star where the other 2 are maxed so definitely a weight difference there.

    Slalom and G-force tests aren't a one dimensional grip test. Mass and width also plays a part in the race. Results are as expected.

    That’s all fine and dandy.  I get that.  I asked to please keep it on track and post in the correct thread, then they get pissy and tell me we don’t know what we’re doing.  🤷‍♂️

    History shows someone making decisions ( 5 seat Bentley race car, 2010 Gallardo Spyder a half second slower than 2009, BTR2 faster than CTR2 just off top of my head) does not know what they are doing.

    the 208 pikes peak should have slick tyres as it was built for a asphalt road, same with the vw idr. 208 wrx all surface tyres, rallycross asphalt and gravel peugeot rallycars need different tyres as they never use slicks in real life

    This is not MRA related, which is solely related to acceleration.  Each of these suggestions should be it's own separate thread in the Corrections forum (if a thread about that car doesn't already exist and can be added to), along with proper proof to back up the suggestion.  Without factual proof, it will not be addressed.  Thank you for your understanding.

    More realistic ? 
    When btr2 is now beaten by btr ? No way

    That is called ruining hierarchy. ML63 now beats GLE63, and Zonda S 7.3 now beats Zonda F.

    But the 2009 Gallardo Spyder has a midrange like a Birkenstock.

    1992 Mazda RX-7 (C49)
    From Autocar issue of July '92: https://www.flickr.com/photos/triggerscarstuff/albums/72157629882070186

    0-60 mph: 5.5 sec -> 6.0 sec

    0-100 mph: 15.10 sec -> 15.8 sec

    0-120 mph: 25.36 sec -> 25.2 sec

    0-130 mph: ~33.26 sec -> 30.9 sec

    1/4 mile time: 14.28 sec @ 98 mph -> 14.6 sec @ 96 mph
    so basically the mid-range is improved from 57.29 to 61.22.

    0-60 mph: 9.5 sec -> 9.9 sec

    0-100 mph: 26.15 sec -> 32.0 sec
    mid-range decreased from 57.06 to 44.80.

    0-100 and 1/4 mile times are correct, no change needed.

    0-125 mph: ~13.44 sec -> 12.8 sec

    MRA error here. 100+hp difference and also 100+kg

    The F was modified for PL12.

    two screenshots because we still can’t compate cars

    yeah, both cars' MRA hierarchy are ruined this update
