Especially on an Accord, I always recommend to stick to the original springs but you can use OEM shocks such as KYB, APM, Showa or Monroe.

Since you've changed your rims, you may as well go with the Eibach + KYB shocks. These brands are proven reliable aftermarket replacements.

Avoid the APEXI from Brothers as those are imitation stuff. Brothers will never sell high quality aftermarket replacement parts. I will only go to Brothers to buy car shampoo, wax and polish.

Yes. if you reuse the original spring, the ride height will remin the same.
