Their manuals have their quirks and it is a firm ride. Too firm in the rear imo. I had grinding into second. The 8th gen and type r has problems with 3rd. The s2k has problems too. Most run either Royal purple or redline mtl. I swapped to redline and the problem went away. The stock fluid is too thin imo. The shift feel is a little notchy and not at all sloppy.
Steering on the si is that same rack as the non si but with a faster ratio. It’s pretty direct and predictable. It can be a little darty for highway use.
I would not recommend a new si as they went to a 1.6 turbo which ruins it for me. You might feel differently about it. My opinion is if you want a new honda the current accord sport is the one to have. A hondata adapter and a tune could put you in a nice place with stock everything. Intake and catback would probably make 230+ wheel.
