Megan Racing Springs?

[rmshort]

I've been creeping the forums for the past year since I got my Yaris and I'm beginning to mod it in quarantine. I'm running 16x7 Konig Backbones with 205/55 Falken Ziex ZE960, and I was looking at springs next. Wondering if the $50-$100 difference in bigger brands is worth it? Anyone tried the Megan Racing springs? I want a slightly stiffer spring, but I would prefer to maintain as much comfortability as possible. Is it more comfortable riding Teins or Eibachs in comparison?

Plans are to get lowering springs, KYB struts & shocks all around, Tanabe Sustec Strut bar, and Spec-d halo headlights+fog lights, and then 20% tint on windows and back while I'm stuck at home. All I've done so far is install Max Brakes ceramic coated rotors and pads, K&N drop-in & Konigs & Falkens. As far as the interior goes, Rockford Fosgate's in the doors and rear, Rockville 8" under seat sub, & Atoto A6 stereo. I went over 230k miles this week, what are frequent high mileage issues with the Yaris? I know I need to do the timing chain soon but should I take care of anything else while I'm at it? Pretty sure my mufflers over-due for replacing as well.

Thank ya'll for all the great info and awesome builds so far!
