I Built a 718 Cayman for $2000 (Dealers Hate This)
Porsche 718 Cayman Wheel and Tire Build Under $2,000: The Complete Fitment Guide
The Porsche 718 Cayman runs a 5x130 bolt pattern. That single fact shapes every wheel decision you will make on this car, and it eliminates roughly 80% of the aftermarket options available to BMW or Honda owners. This guide works within that constraint to build the best possible wheel, tire, and fitment package for under $2,000 on a 2017–2022 718 Cayman or Cayman S.

Key Takeaways
- The 5x130 bolt pattern is the defining constraint — verify every wheel against it before purchasing
- 19x8.5 front / 19x10 rear is the community-validated sweet spot for the 718 chassis
- ET +57 to +65 front, ET +45 to +50 rear keeps you flush without rubbing after a 1.2-inch drop
- Center bore is 71.6mm — hub-centric rings are required if your wheel's bore is larger
- Tire quality outranks wheel brand at this budget — a great tire on a modest wheel beats the reverse
- H&R Sport Springs drop the car 1.2 inches and fill the wheel arch gap that makes stock 718s look like dealer inventory
- Alignment is mandatory after spring installation — non-negotiable, not optional later

The 5x130 Problem (and How to Solve It)
Every wheel decision on the 718 starts here. The 5x130 bolt pattern is Porsche-specific and shared with only a handful of other vehicles. It rules out the entire catalog of wheels designed for the German and Japanese mainstream — no Volk TE37, no Apex Arc-8, no Apex EC-7 in standard fitment. Your verified options at a reasonable price point are:
- Enkei — RPF1 and TS9 both available in genuine 5x130
- OZ Racing — Ultraleggera and Superturismo available in 5x130
- Rays Engineering — select models available, at higher price points
- BBS — CH-R and FI-R available in 5x130, but pricing starts around $3,000 for a set
Do not buy unbranded or Amazon-listed wheels claiming 5x130 fitment. Improperly drilled bolt patterns on a Porsche are a structural failure waiting to happen. Stick to brands with documented, factory-drilled 5x130 offerings.

Wheel Sizing: What Actually Fits the 718
The factory base 718 Cayman ships on 18-inch wheels. The S typically comes on 19s or 20s depending on options. The enthusiast community has converged on 19x8.5 front and 19x10 rear as the correct staggered setup for this chassis. Here is the full fitment spec:
| Position | Size | Offset (ET) | Bolt Pattern | Center Bore |
|---|---|---|---|---|
| Front | 19x8.5 | +57 to +65 | 5x130 | 71.6mm |
| Rear | 19x10 | +45 to +50 | 5x130 | 71.6mm |
Why these offsets matter: The 718 has tight rear arch clearance. An offset below ET +45 at the rear pushes the wheel outward and causes tire contact with the outer fender lip — especially after lowering. An offset that is too high seats the wheel too deep and risks inner fender contact. The ET +45 to +50 rear range is the safe corridor based on community-documented fitment with a 1.0–1.2 inch drop.
Hub-centric rings: Many aftermarket wheels in 5x130 are drilled at 71.6mm natively, but confirm before purchasing. If the center bore is larger than 71.6mm, hub-centric rings are required. Running a wheel without proper hub centering produces vibration at highway speed that no amount of balancing will fix. Rings cost $20–$30 and are not optional if the bore does not match.
Lug bolts: The 718 uses bolts, not studs. Your existing OEM lug bolts will work if the wheel's seat type and bolt length are compatible — verify this against the wheel manufacturer's specifications before installation.
Use the ThreePiece.us 718 Cayman fitment gallery to browse community-submitted photos filtered by wheel size and offset. Real-world fitment photos with documented specs are more reliable than offset calculators alone, particularly for the staggered setup where front and rear behave differently.

Wheel Recommendations: Enkei TS9 and RPF1
Enkei TS9** — Multi-spoke design, available in matte black and silver, approximately $700–$850 for a set of four in the 19x8.5 and 19x10 sizes. This is the value choice that still looks intentional on the 718.
Enkei RPF1 — One of the most tested lightweight wheels in the enthusiast market. Approximately 18–20 lbs per wheel in 19-inch sizes. Street price for a set of four runs $800–$1,100 depending on finish and vendor. At this budget, target the lower end through patient shopping or vendor sales.
Used OEM Porsche wheels — Factory 19-inch Porsche wheels appear regularly on Rennlist classifieds, Facebook Marketplace, and PelicanParts forums. Expect $400–$700 for a set in good condition. They are heavier than Enkei units, but for a street build the unsprung weight difference is minor. The real benefit is freeing up $200–$300 to spend on better tires.

Tire Sizing and Recommendations
The correct staggered tire sizes for 19-inch wheels on the 718:
- Front: 235/35/19
- Rear: 265/35/19
If you opt for 18-inch wheels — a legitimate budget move that lowers tire cost and improves ride quality with the taller sidewall — the correct sizes are 235/40/18 front and 265/40/18 rear. The visual difference between 18 and 19 inches on the 718 is less dramatic than on many other cars because the wheel arches are not oversized.
Tire priority rule: At this budget, tire quality outranks wheel brand. A modest wheel with a quality tire handles better and stops shorter than a premium wheel with a budget tire.
Performance tier — Michelin Pilot Sport 4S or Bridgestone Potenza Sport: The community benchmark for street performance. A set of four in 235/35/19 and 265/35/19 runs $800–$1,000, which consumes the entire wheel and tire budget on its own. Achievable only if you source used OEM wheels cheaply.
Budget tier — Falken Azenis FK510 or Hankook Ventus V12 evo2: Both carry strong reviews in enthusiast forums and deliver genuine performance. A set of four Falken Azenis FK510 in the correct staggered sizes runs approximately $620–$750. Paired with Enkei TS9 wheels at the lower end of their price range, the combined wheel and tire cost lands at $850–$950 with careful shopping.
Deep budget tier — Kumho Ecsta PS91 or Nexen N'Fera Sport: A set of four Kumho Ecsta PS91 in 235/35/19 and 265/35/19 runs approximately $480–$580. This is a legitimate option that redirects $150–$200 toward wheels or suspension.
Add $80–$120 for mounting and balancing at a local shop — this is not included in parts pricing.

How Lowering Changes Your Fitment
The H&R Sport Springs drop the 718 approximately 1.2 inches front and rear. This changes the fitment equation in two ways:
- Arch gap closes — The factory ride height leaves visible gap between the tire and wheel arch that reads as stock. The 1.2-inch drop fills that gap and puts the wheel in the correct visual relationship with the fender.
- Rubbing risk increases — Any offset that was marginal at stock height becomes a rubbing issue after lowering. This is why the ET +45 to +50 rear recommendation is specific to a lowered car. If you are running stock ride height, you have slightly more offset latitude.
H&R Sport Springs for the 718 Cayman run approximately $250–$300. Verify part numbers on H&R's website using your model year and trim — they vary between the base 718 and the S. Eibach Pro-Kit springs are the alternative at $230–$280, with a slightly more modest drop of 0.8–1.0 inches.
After any spring installation, a four-wheel alignment is mandatory. A four-wheel alignment at an independent shop with a Hunter rack runs $100–$180. Porsche dealers charge more. The alignment targets for this setup:
- Front camber: -1.5 to -2.0 degrees
- Rear camber: -1.5 to -2.0 degrees
- Rear toe: slight toe-in for stability
These settings are within the factory adjustment range on most 718s and will not cause abnormal tire wear.

Budget Allocation
| Category | Budget |
|---|---|
| Wheels — Enkei TS9 19x8.5 and 19x10 (set of 4) | $700–$850 |
| Tires — Falken Azenis FK510 235/35/19 and 265/35/19 (set of 4) | $620–$750 |
| Mounting and balancing | $80–$120 |
| Hub-centric rings (if needed) | $20–$30 |
| H&R Sport Springs | $250–$300 |
| Four-wheel alignment | $100–$180 |
| Total | $1,770–$2,230 |
Shop the lower end of each range and you land comfortably under $2,000. Stretch on tires — Pilot Sport 4S instead of Falken — and you need to source used OEM wheels to compensate.

Fitment Mistakes That Will Cost You
Buying unverified 5x130 wheels. Some vendors list wheels as 5x130 that are improperly drilled or converted. Verify the bolt pattern is factory-drilled by the manufacturer, not redrilled from another pattern.
Ignoring hub-centric fitment. A wheel that is lug-centric rather than hub-centric on a Porsche will vibrate at speed. Hub-centric rings are a $25 fix. Skipping them is not.
Running the wrong offset after lowering. An offset that works at stock height may rub after a 1.2-inch drop. The ET +45 to +50 rear recommendation accounts for the lowered position. Going below ET +45 at the rear with H&R springs is a rubbing risk on the outer fender lip.
Skipping the alignment after springs. The 718's suspension geometry is sensitive. Running misaligned after a spring swap produces uneven tire wear across the staggered setup — which means replacing $700 worth of tires prematurely.
Buying cheap coilovers. Budget coilover kits from Raceland and similar brands at $400–$600 introduce inconsistent damping and poor spring rates on a chassis that the factory got right. If you want coilovers, save for KW Variant 3 or Bilstein PSS10 units at $1,500–$2,500. At this budget, H&R springs on stock dampers is the correct call.

Bottom Line
The 718 Cayman's 5x130 bolt pattern narrows your options, but Enkei's TS9 and RPF1 in 19x8.5 and 19x10 are proven, correctly drilled, and available at a price that leaves room for tires and suspension. Run ET +57 to +65 up front and ET +45 to +50 at the rear, verify the 71.6mm center bore, and add hub-centric rings if needed. Pair the wheels with Falken Azenis FK510 tires in a 235/35/19 and 265/35/19 staggered setup, drop the car 1.2 inches on H&R Sport Springs, and get a four-wheel alignment immediately after. That is $2,000 spent correctly on a car that already handles better than almost anything at its price point — and now looks the part.
