Good-Win Racing Mazda Performance Parts
Enkei 17x7.5 RPF1 wheels

These Enkei RPF1 are a personal favorite for their combination of great quality, great finish, strength, lightness and price. Just over 15 pounds each in 17x7.5 size makes this one of the very few 17 inch rims we find appropriate for the NC generation MX5 Miata. Available in SBC finish as seen on our project car above and also in Silver.


Welcome to Good-Win Racing!

Street, Autocross and Track Performance for your Mazda Miata, MX5, MX5ND, Mazda RX8, Mazda RX7, Mazda 3, Mazda 2, Mazda 6 and CX5.

Why Zoom with Mazda parts from Good-Win Racing?

Because we race what we sell, and we share our expertise with you!

When our competition goes home for the weekend, we go racing and driving in our Mazda! Using the Mazda parts we sell, under both street performance and race conditions, gives us a unique experience on what works, and what doesn't.

From shock absorbers, replacement convertible tops, and shift knobs, to exhausts, intakes, springs, and alloy wheels, we can help you select the right combination of Mazda parts.

You can also join our Mazda Forums for more information about specific parts and cars, as well as development of our current project cars. And don't miss our forum wheel gallery to see what those wheels you are considering actually look like on your Mazda before you buy.

Next Tech Day is Saturday March 5th!

REVIEWS

Just wanted to thank you guys for the great stuff and great work done on my MX5 club yesterday. I could feel the difference in sound and performance right away! It drives and corners awesome now. Can't wait to tell my friends about you guys. I'll be keeping an eye on your web site for other goodies and events as well. Can't wait to try my new suspension out on a auto cross. Will definitely be trying it on some twisty roads this weekend. Just can't wipe that smile off my face when driving this car. Thanks again guys!

Hey Brian, Recieved my Borla Dual Muffler Sport today from Fedex, and installed it in about 30-45 minutes. An Outstanding product with absolutely no drone throughout the power band, it sounds powerful, not at all like one of the ricey "fart tubes" that can be found elsewhere online. It has perfect like OEM fitment. Great prices, and great products. Product was shipped promptly and arrived as ordered. Would buy again!
