Do last gen brake pads fit new gen?

But we all know the stock brakes are designed to stop the vehicle hard once, maybe twice before being given a break to cool..

I see the advantage in better pads, higher boiling point fluids and even larger brake systems in maintaining stopping power under aggressive driving conditions, but not in increased 'stopping power'.

Even when you get into large monobloc multi piston calipers, my understanding is that they are not about applying more clamping force, they are about being able to use larger (and often times thicker) pads and still applying that force evenly across the pad surface. As well as the ability to user larger, thicker rotors with better heat tolerances, and often better venting systems for shedding that heat. Ultimately it is all about managing heat better.

I think this term is a bit misleading to the uneducated, and may lead to the belief they will get shorter stopping distances, which given the same tire, isn't likely to be true..

More 'stopping power' would require more capable tires to be utilized, otherwise it would just be wasted anyway. Aren't we really talking about maintaining stopping power, pedal feel and hopefully increasing the life of the pad/components in the process?

Thumbs up on what you said….good performance brake pads can shorten braking distance and do so over and over compared to oem and that’s what I’m looking into. I’m running kw V3 on 255 PS4S tires. Substantial performance/grip upgrade from stock. Hence the reason for needing/wanting more consistent stopping power.

I’ve called about four Subaru dealers and spoke to the parts department and they all claim the pads from last gen are different with different part numbers.
Maybe different pad material hence the different part number?

Most likely different material, but physically same..

Reach out to https://www.essexparts.com/brake-pads support and ask them. I'm pretty sure I saw a post that they had a 2022 in to evaluate, they can probably tell you for sure..

Gen2 stock pads have a different/better compound compared to Gen1 stock pads but dimensionally the same. Hence Gen2 stock costs more.

Correct, the pad material is different. This was discussed in one of the official Toyota/Subaru press releases.

It's supposed to be better at heat than the first gen, but still not really track capable.

New regulations require brake pads to reduce the copper content. With that, new pads needs to be developed.

Mkt mambo jambo will say those are better…but there are challenges on changes like that.
