WHY do you want a heavier clutch pedal for? I doubt you will put another 145K on your Accord.
Stick to OEM which isin't as expensive as you think. Most people don't even bother looking up prices of OEM parts.
Honda doesn't mark them up a crazy amount. $126.46 for the OEM pressure plate, $110.13 for the friction disc, $70 for the release bearing, all Japanese superior quality.
But young guys that own older Hondas rice them up. https://www.cheaperhondaparts.com
