The AMG GT3 is just solid everywhere, not really META anywhere but you can always get a good result. The SLS was a decent car pre-update, not as solid as the GT3 but had good tyre wear so was ok once it came to the race - I'd have said very similar to the GT86. The last update probably hit the SLS harder than most. Not necessarily the 1% weight increase (maybe quarter of a second on an average length lap?), but most other cars had either an improvement or less of a handicap and it's hit the SLS really badly as a result. People just aren't bothering with the Gr.4 races with it and I don’t blame them
Could just be Wong Baguette's (Beauvois) fault for winning the series!
