13x7 Super Cooper S wheel (Now In Stock)























13x7 Super Cooper S wheel (Now In Stock)
Our new wheels were specifically designed to improve traction in high performance Minis.
Introducing our brand new Super Cooper S wheel made from Heat treated S356 Aluminum alloy wheel with stainless steel hubcaps, specifically designed to complement Sport pack arches and our favorite TOYO R888R tires. These are premium wheels with steel inserts for added strength. Available in your choice of silver or custom finishes, these wheels are the perfect addition to any standard Mini or modified Vtec. We offer two different wheel offsets to ensure a perfect fit for your vehicle. Our wheels are offered with a variable bolt pattern and customizable backspacing that will be drilled and milled to your spec. The standard Mini 13x7 option is is offered with a traditional 4x101.6 bolt pattern with a +10 offset. The Vtec option is milled down to accommodate the wider track of the Minitec MTB2 subframes. Please note that the price listed is per wheel and includes one hubcap, valve stem, and Lugnuts. Shipping is not included.

Practical guidance for selecting Tires
Gas builds 100–500 hp:
Front wheel drive Up to ~220 whp: R888R 185s are fine with a good LSD.
Rear wheel drive Up to ~500 whp
230–300+ whp: expect spin in 1st/2nd; add torque maps by gear,
Tesla-based ~300 hp EV: strong low-rpm torque = earlier wheelspin; gear/torque limits are your friend.
🔍 Fitment & Contact Patch Considerations for Your Build
Given your sub-2000 lb Mini with power ranging potentially up to 500 hp (or even the 300 hp EV option), we evaluate how each tire might handle the load.
Toyo R888R
The 185/60 section is a bit wider than the 175, giving you more rubber on the road, and the “race compound” means higher usable friction when warmed.
Because your car is light, a high-grip tire like this can translate into better traction and more usable power before wheelspin, especially in 1st/2nd gears.
However: because it’s a semi-slick and optimized for dry track conditions, on street usage (cold, wet, rough surface) you’ll likely see less margin and may need to manage torque delivery (via engine tune, LSD, etc.).
Sidewalls may be stiffer (less flex) which is good for responsiveness but may transmit more harshness and need proper suspension tuning.
For a build that pushes into the 300-hp-plus zone (especially EV torque) this tire gives you a better platform for high grip and high load.
Yokohama A539
With 175 width and profile 50, the footprint is smaller. For a light car, this might be entirely acceptable, but it reduces maximum potential grip compared to a wider, softer compound tire like the R888R.
Good for general street use and moderate power. If your power is modest (say 100-200 hp) and you want ordinary road usability (wet, daily drivers, less track), this is a more balanced choice.
It will be easier on sidewalls maybe, more forgiving, possibly better in wet or colder conditions than a semi-slick. But will limit the top end of traction in aggressive launches or high-corner loads.
📈 Estimated Power Handling / Traction Implications
Here’re approximate guidance for each tire on your build, keeping the sub-2000 lb weight in mind:
Toyo R888R 185/60 R13~220-260 whp (dry, good surface, optimized setup) High grip, but need warm-up, good camber, LSD etc.
Yokohama A539 175/50 R13~150-190 whp (street use) or ~200 whp in very good conditionsGood for moderate builds, less margin for big torque/launch.
Note: “whp” (wheel horsepower) is approximate and strongly dependent on surface, suspension, diff, torque delivery, and driver technique. Actual usable power may vary.
🧭 Recommendation Based on Build Focus
If your build is aiming for serious performance (300+ hp, EV torque, track use, strong launches), go with the Toyo R888R. Pair it with proper suspension, LSD, camber, and manage cold/wet conditions accordingly.
If your build is more street/road oriented (e.g., 150-200 hp, frequent road use, occasional track), the Yokohama A539 offers a more practical balance of everyday usability, good grip, likely better in wet/cold, and lower cost/complexity.
If you plan to progress power later, you might choose the A539 now and upgrade to the R888R when you push beyond ~200-220 hp.
