The Short Version
- Every WRX S4 we found is 5×114.3. That covers the 2014–2021 VAG cars and the 2021-on VBH cars with the 2.4-litre engine.
- The offset is +55 on every row except one. The only exception is the 19-inch STI Sport ♯, which is listed at +53.
- The rim width depends on the grade. The base GT runs 18×7.5J on a 225/45R18, and the STI Sport and the later cars run 18×8.5J on a 245/40R18. Same pattern, same offset, different wheel.
- The hub bore is the number we could not confirm for most of these cars. See the last section.
Same Pattern, Three Wheel Sizes
The databases date the first WRX S4, the VAG with a 2.0-litre turbo, to August 2014. Subaru’s own announcement on 25 November 2021 introduced the new generation with a 2.4-litre turbocharged engine, which the databases list as the VBH.
The wheel fitment did not follow the engine. Across ten years the pattern and offset hardly moved, but Subaru offered 18-inch wheels in two widths and 19-inch wheels on some grades. A listing that says only “WRX S4 wheels” can mean any of them.

Read from two Japanese wheel databases, Spec Tank and Cars Japan. Cars Japan’s WRX S4 model page lists every grade and period. We then opened individual Spec Tank pages for the 2014 GT, the 2016 tS, the 2018 STI Sport and the 2021 GT-H and STI Sport R, and the sizes and tyres match the Cars Japan table on all of them. This table groups the many grades into the main groups, so it is not a complete list: limited editions and some mid-year changes are not shown.
What This Means When Shopping
5×114.3 is one of the most common patterns in the JDM wheel market, so the pool of wheels is large. The risk is not the pattern, it is the size. Match the rim width and tyre size to the grade before you assume a set is right: a 7.5J GT wheel and an 8.5J STI Sport wheel have the same pattern and the same offset, but different widths and tyres.
Do not treat a wheel as a WRX S4 fit because it came off another Subaru. Our WRX STI guide and Impreza WRX GC8 guide cover those cars separately, and each car should be checked on its own numbers.
If an aftermarket wheel has a centre bore larger than the hub, it needs a hub-centric ring. Our hub bore guide shows how to measure the bore yourself, which is the safest route for this car given the gap described below.
Sizing
The factory range is 18 inches in 7.5J or 8.5J and 19 inches in 8.5J, all at +55 except the +53 on the STI Sport ♯. We have not measured clearance for any aftermarket size on any of these cars, so we do not recommend one. Front and rear are the same on every row we opened.
Importing
The databases list the first WRX S4 from August 2014. In the US, the 25-year import exemption (49 CFR 591.5(i)) applies to a vehicle that is 25 or more years old, counted from the date of manufacture. On that reading no VAG can qualify before 2039 and no VBH before 2046, and we have not verified the month the first cars were built. We did not check the import rules of other countries for this guide.
What We Could Not Verify
- The hub bore. Spec Tank lists it as “under investigation” on every page we opened. Cars Japan prints 56 mm only for the newest VBH rows and leaves it blank for the older cars. Subaru’s own support FAQ says its published specification sheets for the VBH cars list the hub diameter, but those files are PDFs that we could not open. Measure the bore yourself, or ask Subaru, before you rely on a number.
- The tyre size on the later GT-S cars and the STI Sport ♯. We checked the tyre on the grades marked in the table only.
- Limited editions and mid-year changes. The databases list many more rows than the table shows, and we did not check each one.
- Wheel weight and material, which the databases do not record.
- The wheel-nut seat type. None of the sources we read state it.
- Real-world clearance of any aftermarket wheel.
