Acura RSX Type S build under $8000: The Truth Nobody Ment...
Acura RSX Type S Wheel and Tire Build Guide: Everything You Need to Know About DC5 Fitment
The Acura RSX Type S runs a 5x114.3 bolt pattern on a 64.1mm hub bore. Stock Type S wheels are 17x7 +55 on 2002–2004 cars and 17x7.5 +55 on 2005–2006 cars, both wrapped in 215/45R17. That factory setup is conservative — narrow contact patch, high offset, modest grip. A proper performance build moves to 17x9 +35 with a 235/40R17 tire, and the difference in steering feel and cornering grip is immediate and significant.
This guide covers every wheel and tire decision for a DC5 RSX Type S build under $8,000: the right fitment specs, the best wheel and tire combinations at each price point, what to watch for with offset and clearance, and how to verify your setup before you buy.

Quick Answer
Run Enkei RPF1 17x9 +35 with 235/40R17 tires** on a DC5 RSX Type S lowered 1.5 inches on coilovers. This is the community-proven performance setup. Expect minor front fender liner trimming at full lock. Hub bore is 64.1mm; bolt pattern is 5x114.3. Verify your exact combination on ThreePiece.us before purchasing.

Key Takeaways
- Stock Type S offset is +55 — moving to +35 widens the track and improves cornering feel
- 17x9 is the widest practical street fitment on the DC5 without fender work
- 235/40R17 is the correct tire size for a 17x9 rim on this platform
- Enkei RPF1 17x9 weighs approximately 16.5–17 lbs — unsprung weight reduction is immediately noticeable in steering response
- Coilovers must be installed and the car aligned before finalizing wheel clearance
- ThreePiece.us has a DC5-specific fitment database with real owner photos organized by wheel size, offset, and suspension setup
- Hub bore is 64.1mm — confirm this on any aftermarket wheel before purchasing
- Hubcentric spacers from Eibach or H&R are acceptable; unbranded spacers are not

DC5 RSX Fitment Specs You Need to Know
Before any wheel purchase, these are the hard numbers:
- Bolt pattern: 5x114.3
- Hub bore: 64.1mm
- Stock Type S wheel size: 17x7 +55 (2002–2004), 17x7.5 +55 (2005–2006)
- Stock tire size: 215/45R17
- Performance target: 17x9 +35 with 235/40R17
The jump from +55 to +35 offset pushes the wheel face outward by 20mm, widening the track and improving cornering stability. At 17x9 +35 on a DC5 lowered approximately 1.5–2 inches, the front wheels sit close to the inner fender liner under full compression. Most owners report clean fitment with minor fender liner trimming at the front. The rear is more forgiving at this offset.
Running 245-width tires on a 17x9 is possible but tight on the DC5's front end under coilover suspension. 235 is the correct street choice.

The Right Wheel: Enkei RPF1
The Enkei RPF1 in 17x9 +35 is the benchmark wheel for this platform. It has been the DC5 community standard for over a decade, and the reason is simple: it is one of the lightest cast wheels available at its price point.
- Weight: approximately 16.5–17 lbs in 17x9
- Price: approximately $185–$210 per wheel, $740–$840 for a set of four
- Finish options: Racing White, Matte Black, Silver, Gunmetal
Reducing unsprung weight improves suspension response and steering feel in a way that is immediately noticeable on a canyon road. The RPF1 delivers that benefit without requiring a forged wheel budget.
Lower-cost alternatives:
- Konig Hypergram — approximately $100–$130 per wheel. Lighter than many competitors at this price; functionally similar to the RPF1 for street use.
- Motegi Racing MR143 — approximately $100–$130 per wheel. Solid value option in the same weight class.
Higher-cost alternative:
- Volk Racing TE37 — approximately $400–$600 per wheel. Forged construction, significantly lighter than cast alternatives. The benchmark for this platform if the car sees regular track use.

Tire Selection: Performance Street to Budget Performance
The correct tire size for a 17x9 on the DC5 is 235/40R17. Here are the best options at each price point.
Premium street:
- Michelin Pilot Sport 4S — approximately $185–$220 per tire ($740–$880 for four). The benchmark for ultra-high-performance street tires. Excellent wet and dry grip with reasonable longevity.
- Continental ExtremeContact Sport 02 — approximately $150–$185 per tire. Very strong dry performance, competitive with the PS4S in most tests.
Budget performance:
- Falken Azenis RT660 — approximately $130–$155 per tire ($520–$620 for four). Near-competition-grade grip at a budget-friendly price. Treadwear rating of 200 means shorter life than the PS4S, but dry grip is excellent. Strong reviews across DC5 and broader Honda enthusiast communities.
- Hankook Ventus V12 Evo2 — approximately $110–$135 per tire. Good dry grip; wet performance is slightly behind the top-tier options.
Track-only (not recommended for daily driving in wet climates):
- Michelin Pilot Sport Cup 2 — approximately $250–$320 per tire. Near-slick dry grip; unsuitable for daily use in rain.
Add approximately $80–$120 for mounting and balancing at a tire shop.

How to Verify Fitment Before You Buy
Buying wheels without confirming offset and hub bore is the most common and expensive mistake on this platform. A wheel with the wrong offset rubs on suspension components or protrudes past the fender. Always confirm three numbers before purchasing any wheel for the DC5:
- Bolt pattern: 5x114.3
- Hub bore: 64.1mm (a wheel with a larger bore requires a hubcentric ring to center correctly)
- Offset: 17x9 +35 is the target; deviating significantly in either direction creates clearance or stance problems
ThreePiece.us is the most useful tool for this. The site aggregates real-world fitment photos from owners, organized by vehicle, wheel size, offset, and suspension setup. Searching the DC5 RSX database shows exactly what a 17x9 +35 looks like on a lowered RSX, what tire sizes owners are running, and whether fender work was required. Cross-reference any wheel and tire combination on ThreePiece.us before purchasing.

Offset, Spacers, and Clearance
If a wheel you want is available only in a higher offset than +35 — say +45 or +50 — a hubcentric wheel spacer can push it outward to achieve the correct track width. Acceptable spacer brands are Eibach and H&R. Unbranded spacers introduce hub bore centering errors and are not acceptable on a performance-driven car.
Practical spacer range for the DC5: 5–10mm. Beyond 10mm, the additional wheel bearing load becomes a meaningful consideration over time.
At stock ride height, a 17x9 +35 may require fender liner trimming at the front under full lock-to-lock steering. With coilovers set at 1.5 inches of drop, most DC5s clear this fitment without modification. Confirm on ThreePiece.us with your specific coilover and drop measurement before assuming clearance.
---
Suspension and Alignment: What They Mean for Wheel Fitment
Wheel fitment on the DC5 cannot be evaluated independently of suspension setup. Coilover drop changes the relationship between the tire and fender at full compression, and alignment settings determine how much of the tire contact patch actually reaches the road.
Coilover recommendation: Fortune Auto 500 Series, approximately $1,250–$1,450. At 1.5–2 inches of drop on street valving, this is the setup most DC5 owners use with 17x9 +35 fitment.
Post-suspension alignment targets for 235/40R17 on 17x9:
- Front camber: -1.5 to -2.0 degrees
- Front toe: 0 to +0.5 degrees
- Rear camber: -1.5 degrees
These numbers maximize tire contact during cornering while keeping street tire wear acceptable. Do not install wheels and tires before the alignment — it wastes a tire wear cycle.
Rear camber note: The DC5's rear suspension has limited camber adjustability. If the rear shows more than -2.5 degrees after coilover installation, rear camber arms — Skunk2 or Ingalls, approximately $80–$150 — are necessary to prevent accelerated rear tire wear.
Camber plates: If planning any track use, Skunk2 Pro Series front camber plates (approximately $150–$180) allow front camber adjustment beyond the stock strut top range and are necessary for achieving the alignment targets above.

Bottom Line
The DC5 RSX Type S responds dramatically to the right wheel and tire combination. Moving from the stock 17x7.5 +55 with 215/45R17 to a 17x9 +35 with 235/40R17 widens the contact patch, lowers unsprung weight with the right wheel choice, and transforms the car's cornering behavior. The Enkei RPF1 is the correct wheel for this build at this budget. The Falken RT660 delivers near-competition grip without the Michelin price. Verify every combination on ThreePiece.us before you buy, confirm hub bore is 64.1mm, and get a proper four-wheel alignment the same day the coilovers go on.
