We can also ship worldwide from Japan - several countries are already incorporated into the checkout system and I’m still adding more.
Redpants Updates
A lot has been going on lately and I haven’t had the time to update the Latest Products or Latest Website Content sections below in quite a while, so they’re pretty outdated. Check out my recent posts in my Blog for more updates and to keep current.
SHIPPING NOTICE: The US Government has suspended its de minimis exemption and now virtually all shipments going into the US are subject to the Trump Administration’s new tariffs. I’ve discussed this in a few Blog posts starting as far back as September so please take a look at those if you aren’t aware of the current situation.
SHIPPING NOTICE: Hawk and Porterfield brake pads will not be shipping from November 20th to December 1st, 2025. Any orders placed for them during that time will begin shipping on December 2nd.
For current discounts and promotions, check out my Promotions page.

This is the Search Bar. It’s probably the only non-alcoholic bar you’ll ever see me use. Strange concept, I know. But hey, there’s a ton of info on Redpants and this thing works… kinda… so give it a try.
