Anyone here tried both racing RON 102 and the regular pump version in their GR86? same octane rating, but I'm wondering if the racing stuff has better additives or burn properties but maybe improved knock resistance or smoother throttle under load? is it actually worth the extra coin, or mostly marketing?

I never tried the racing one, but all I know is that it's designed for high-performance vehicles, it optimizes combustion, increases power, and enhances durability. not for everyday usage

Whether it's worth the extra dough for a daily driver like the GR86 is a real toss-up. Unless you're tracking it hard, you might not feel a huge difference to justify emptying your wallet faster.
I'd still consider myself a newbie but I've ran both my local 91 octane pump premium and a couple of tanks of RON 102 in my GR86.
While the RON 102 definitely felt smoother under hard acceleration and perhaps a touch more responsive, especially when pushing it in higher RPMs, the difference wasn't groundbreaking. I didn't notice any dramatic change in knock resistance on the stock tune, as the car's ECU is pretty good at adapting. But I can't say for sure because I might not have enough experience as a new owner!
For daily driving or even spirited street use, I'd say it's mostly marketing for the GR86. The cost difference quickly adds up, and the tangible benefits aren't significant enough to justify it over regular pump premium. If you're running a highly tuned engine or regularly tracking the car, then maybe it's a different story for the peace of mind or that last fraction of a percent performance.
