So, I've heard a couple of thoughts here that I'd like to summarize, perhaps challenge, and maybe eek out just a little more conversation.
The factory design is fine
- it's "fine", but really not great. On my German cars I'm usually an OE guy but here I think I can do better, which means some aftermarket parts but performance is the key while still maintaining daily driving safety (e.g. cold performance) and fit (e.g. pads don't rattle around in the calipers because of poor tolerances)
Yellowstuff is for racers
- I have heard in the meantime that Yellowstuff is different between "cars" and "truck and SUV". That means that Sienna "Yellowstuff" might not be the same as Miata or GTI "Yellowstuff" in terms of formulation and performance. There are a lot of different members here with a lot of different cars - I'm quite interested in minivan Yellowstuff just as a datapoint. Thanks to those pointing out other good options like R4S. I don't have a place in Canada to purchase yet but working on it.
Sources for quality rotors
- don't have many choices for high quality in Canada. Was surprised to hear some criticism of Centric, which I thought were alright. Will keep looking.
- I haven't been able to find a source I can use for Pagid pads for Sienna anywhere.... I'd be interested in some more info on their pad formula. And if they make high-carbon rotors for Sienna. I have Pagid two piece high carbon rotors on my 535 right now (might be Pagid pads too) and I've been quite happy (happier than factory). I'd absolutely consider trying "Euro OEM" brands on the Sienna, but would like first hand feedback.
