I mean, suspension wise (to include strut braces and such), yes. Intake, yes. Other performance aimed motor mods? Not really. And as far as aero...one company (Mapisa) makes a kit and another (albeit an eBay 'brand') makes a modified FRS lip that fits now. If I'm being honest, I think the Mapisa kit that provides a front lip, side skirts, rear bumper lip(s), and trunk lip doesn't look bad for the most part but the ones for the S and XSE models is lacking. I have seen headlight and tail light options now though so guess thats good.
Whereas with Civics, the Corollas direct and only real competitor, has boat loads of options out there for everything almost immediately. Granted, we don't need lots of performance mods but even options to do motor swaps would be nice. I think these are too new for that kind of attention though and Toyota enthusiasts are more into stancing Corollas than making them race-able...so it'll probbaly never happen really.
I wish Toyota would get back to more performance options for all models rather than just for the coupe (soon to be plural with the new Supra) and for the trucks.
And yeah, I follow him on Insta and was saddened to see that had happened to him. But, glad he got the Lexus he did. He's talking about a full stanced, VIP look I'm pretty stoked to see how he does it.
