I've read that the matrix trd rear sway bar is a direct bolt on. I'm wondering what other parts would possibly be a direct swap? Coilovers? Intakes? Etc. Aren't the yaris engine & prius engine similiar?
I wish someone knew the answer to this. I have the TRD struts/springs in my '05 Prius and they have over 100K miles on them now and I want to replace them with another performance strut. Only KYB seems to make anything for these cars but KYB has a bad reputation and seem to be of poor quality with numerous complaints of failure within a short period of time. I would love some Koni's. I do have the Matrix rear bar and it was a direct bolt-in replacement that was much more stout than the stock bar.
The SCCA Solo II FSP Prius used Celica and Matrix front struts and rear suspension. http://priuschat.com/forums/gen-ii-prius-main-forum/16285-prius-scca-solo-ii-fsp.html
