Enkei RPF1: The Lightweight Track Classic
The Enkei RPF1 is a six-spoke, thin-spoke racing wheel built for drivers who want to cut rotating weight without giving up strength. It's a monoblock wheel, so the entire face and barrel are cast as a single piece, and the open spoke design keeps brakes breathing on track days and spirited street driving alike. It sits among Enkei's motorsport-focused offerings on the wider Enkei brand page, and remains one of the most fitted wheels in the aftermarket.
Sizes and Fitments in Stock
We stock the RPF1 from 14 to 18 inches in widths of 7, 7.5, 8, 8.5, 9, 9.5, 10 and 10.5. Offsets run a full range from +15 to +48, so there's room to dial in a flush setup or a conservative daily fit. Bolt patterns cover 4x100, 4x114.3, 5x100, 5x112, 5x114.3 and 5x120, spanning most Honda, Miata, Subaru and Euro applications.
Concrete examples: the popular 14x7 +19 in 4x100 Silver and its 14x7 +28 sibling suit lightweight Hondas, while 15-inch buyers often reach for the 15x7 +41 or 15x7 +35. For 16-inch builds, the 16x7 +35 in 5x114.3 covers a huge range of chassis.
Finishes
The RPF1 comes in 12 finishes: Silver, Matte Black, Black, Gloss Black, Gold, Victory Blue, Emerald Blue, Matte Blue, SBC, Vanquish White, Competition Red and Orange. Browse by color across our Silver, Black, Gold, Blue and White Enkei pages.
Price and Who It Suits
The RPF1 runs from $215 to $616 per wheel depending on size and finish. It's aimed at track-day drivers, autocrossers and street enthusiasts who prioritize low weight and proven strength. If you want a different look, the Compe offers a classic mesh face, the EV5 is a lighter multi-spoke option, the EDR9 leans toward budget daily use, and the Giotto brings a five-spoke split design. The rugged BHAWK suits heavier applications.

The RPF1 is the light wheel people put on cars they actually drive hard, from old Miatas to new WRXs. This guide helps you pick the right diameter, width and finish, and shows what real owners run. Use it to narrow things down, then confirm your exact car in the fitment search.
Popular designs, side by side
Enkei RPF1
A light one-piece track wheel with thin spokes and a flow-formed barrel, built to cut weight at each corner. It suits small 4x100 cars like Miatas and older Civics in 15 and 16 inch, and 5-lug Subarus, Nissans, Hondas and VWs in 17 and 18 inch. The size spread is the big draw: 15x7 all the way up to 18x10.5, so it works on a stock-height daily or a wide, flush track car. One honest consideration: the wider and lower-offset sizes push the wheel out fast, so check fender and brake clearance for your exact car before ordering.

Which RPF1 size for which car and use
Start with diameter, then width. Smaller wheels weigh less and leave room for more tire sidewall. Bigger wheels clear bigger brakes and fit the wide, sticky tires most track cars end up on.
| Diameter | Widths in stock | Best for |
|---|---|---|
| 15 inch | 7, 8 | Light 4-lug cars like NA and NB Miatas and older Civics. The lightest setup, and tires in this size are cheap to replace. |
| 16 inch | 7, 8 | Small 4x100 and 5x100 cars that need a bit more brake room than a 15 gives. A sensible street and autocross size. |
| 17 inch | 7, 7.5, 8, 8.5, 9, 9.5, 10 | Most 5-lug cars on track tires. 17x8 and 17x9 are the deepest sizes we carry, and the wide 17s are a favorite on lightweight rear-drive cars. |
| 18 inch | 7.5, 8, 8.5, 9, 9.5, 10, 10.5 | Newer WRX and STI, Civics, Z cars and VWs with bigger factory brakes. Room for 245 to 275 tires depending on width. |
Rule of thumb: go as small as your brakes allow and as wide as your fenders allow.
Popular cars by bolt pattern
Bolt pattern is the first filter. Here are the common cars on each pattern we carry.
| Bolt pattern | Popular cars | Shop |
|---|---|---|
| 4x100 | 1990-2005 Mazda Miata (NA and NB), 2016-and-newer Miata (ND), many 1990s and early-2000s Honda Civics | every 4x100 option |
| 5x100 | Subaru BRZ, Scion FR-S, Toyota 86 and GR86, 2002-2014 Subaru WRX | 5x100 sizes for the twins and older WRX |

| 5x112 | VW GTI, Golf R and many Audis | 18x9 +35 for GTI and Golf R |
A matching bolt pattern does not mean the wheel fits. Enter your year, make and model in the fitment search to see which offsets and widths work on your exact car. Civic owners can also read the 8th gen Civic fitment breakdown for daily, track and stance setups.
Enkei RPF1 18x9.5
This is the size people search for most, and it is a strong pick for modern Subarus. It comes in two very different offsets, and that choice changes everything about how it sits.
- +38: the tucked, conservative version. A 2011 WRX STI owner runs it square with 245s and gets a flush fit. Grab the 18x9.5 +38 in Silver or the same size in SBC.
- +15: the aggressive version. A 2015 WRX owner runs it square with 225s, flush. See the +15 in Silver or the +15 in Gloss Black.
A 23-point offset gap is huge. Don't pick by looks alone. Check your car first.
How RPF1s look on real cars
These are real customer builds. They show what works, but suspension, camber and fender work vary, so treat them as a starting point, not a guarantee.
- 1992 Mazda Miata: 15x8 +20 square with 225s, flush. The classic Miata track look.
- 1994 Honda Civic del Sol: 15x8 +28 square with 205s, nearly flush. Pick it up in Silver, Black or Gold.
- 2003 Subaru Impreza: 18x7.5 +20 square with 225s, flush.
- 2006 Subaru Outback: 18x8 +35 square with 235s, flush. Proof these aren't just for track cars.
- 2016 Subaru WRX: 18x10 +38 square with 255s, flush. About as wide as a WRX goes without big changes.
- 2015 Lexus IS350: 18x9.5 +45 front and 18x10 +38 rear, 235s up front, flush.
- 2009 Mazda RX-8: 17x10 +38 square with 275s, flush. A lot of tire on a 17.
- 1990 Nissan 240SX: 17x9.5 +22 front and 17x10 +18 rear, 235s up front, flush.
- 1992 Nissan 240SX: 17x9 +27 front and 17x10 +38 rear, 225s up front, flush.
- 1996 Nissan 240SX: 18x9.5 +0 front and +10 rear with 215s up front, flush. Low offsets like these usually mean fender work.
Track day and autocross use
Every pound at the wheel is weight the springs, shocks and brakes have to control. Lighter wheels help the car turn in sharper, put power down cleaner and stop shorter. You feel it most in quick transitions, which is exactly what an autocross course throws at you.
The RPF1 stays light through thin spokes and a light one-piece build. The open face also lets air reach the brakes, which matters in long sessions.
Two things to check before a track build:
- Brake clearance. Big brake kits and some factory performance brakes need more room behind the spokes. Bigger diameter helps, but offset matters too.
- Tire width. Match width to the tire you plan to run. Stretching a tire or bulging one on a narrow wheel both hurt grip.

How to pick offset without guessing
Offset decides whether a wheel tucks, sits flush or pokes past the fender. Lower numbers push the wheel out. Higher numbers pull it in toward the suspension.
Don't guess from a forum post. Put your year, make and model into the fitment search, and it will show which RPF1 widths and offsets work on your car, including brake clearance. If you already know your current wheel and tire specs, the offset and poke calculator compares them to a new size and shows how much further out or in the new wheel will sit. Lowered cars, camber changes and rolled fenders all shift the safe range, so plug in your real numbers. Want to compare other lightweight options first? Browse the rest of the brand's lineup.
Questions
Is the RPF1 good for track days and autocross?
Yes, it's one of the most popular wheels for both. Low weight helps the car change direction and brake harder, and the open face lets the brakes cool.
Will an 18x9.5 RPF1 fit my car?
It depends on your offset, brakes and fenders. The +38 and +15 versions sit very differently, so enter your car in the fitment search before you buy.
Is the RPF1 a one-piece wheel?
Yes. It's a single-piece wheel with a flow-formed barrel, which keeps it light and simple to maintain.
Can I run different widths front and rear?
Yes, a staggered setup works as long as both axles use the same bolt pattern and each wheel clears its corner. Check the front and rear separately in the fitment search.
How do I know if the RPF1 clears my brakes?
Search your exact car in the fitment search, which accounts for brake clearance. If you run an aftermarket brake kit, bigger diameters give you more room.
What does the wheel fitment calculator do?
It compares your current wheel and tire against a new size. It shows how much the new setup will poke out or move inward so you can spot rubbing before you order.
