My most recent purchases have been all the megan racing lower support bars plus a nice set of sticky yokohama high performance tires
this combo should improve my lateral g's and overall handling. I've checked on yaris forums about the bars and ppl have alot of positive reviews. One guys even recommends them for autocross usage (with combo of sway bar and strut bar aswell) so hopefully theyll both be in and installed. i'll put up a review as well stating any noticable differences in handling.
