STREET/TRACK APPLICATIONS (OCCASIONAL TRACK USE – CIRCUIT / TIME ATTACK / ROAD RACING)

The Super Copper Kit brings a new level of performance to the street and track.

It’s built with the highest copper content you’ll find in any organic clutch on the market — giving you a better grip than OEM, better heat tolerance, and more consistent performance on and off the track. Backed by a reinforced steel plate and a copper-loaded organic facing, it’s designed to hold more power without giving up smooth street drivability.

This kit uses our reinforced steel-backed, copper-loaded organic disc paired with a heavy-duty single diaphragm pressure plate — delivering smooth engagement you can daily drive, and the grip you need when you push it. It’s the ideal setup for stock, tuned street cars and basic bolt-on builds that want more without giving up drivability.

Like all of our sprung kits, the Super Copper features our patented fully enclosed spring retainer system — protecting you from failures that can cause serious transmission or engine damage, a problem we guarantee you’ll see with other brands.

Every kit is hand-assembled and signed off after multiple quality checks by our senior engineering team (50+ years combined experience), making sure you’re getting real, tested performance — not guesswork.

Pressure Plate Features

  • Ductile Iron Friction Plate for heat control
  • Reinforced Heavy-Duty Drive Straps
  • 4-Stage Heat Treated Diaphragm Spring for durability
  • American-Grade Rivets
  • 100% Dynamically Spin Balanced for smooth operation

Clutch Disc Features

  • Steel-Backed, Super Copper-Loaded Organic Friction Material
  • Fully Enclosed Patented Spring Retainer System for long-term protection
  • Sprung Hub for easier, smoother engagement
  • American-Grade Rivets for maximum strength
Note:
The Super Copper Series is your go-to clutch for daily-driven, tuned, or bolt-on builds. It drives smooth, handles stock-mid power, and stays strong when it heats up.

Soft, true-fit briefs — great daily comfort, not ideal for workouts
Color: Black, Size: Large
I’ve been wearing these wirarpa modal briefs every day for about a month, and they’ve quickly become my go-to pair for daily wear. I previously owned the same brand’s boxer briefs for over a year, which held up better than any other brand I’ve tried, so I decided to test the brief version this time. Fit and Comfort The sizing was spot-on for me. The waistband is soft, not scratchy, and doesn’t dig in — it stays in place without rolling. The leg openings don’t ride up, and everything stays comfortably supported without tight seams in the wrong spots. I’d almost forgotten how briefs feel after years of wearing boxer briefs, but these reminded me why they’re still worth owning. Fabric and Wearability The modal material is silky and smooth to the touch. It’s perfect for everyday comfort and casual wear, but not the best choice for sports — it’s not highly moisture-wicking, so I wouldn’t use them for workouts or hot outdoor work. Durability After a month of daily washing, there’s no pilling, stretching, or loose stitching at all. If they hold up like my year-old wirarpa boxer briefs, I expect these to last far longer than most big-name brands. Design Notes These come neatly rolled in a sealed bag with no odor or chemical smell — a nice touch that shows some quality control. Bottom Line If you like a soft, lightweight brief that fits true to size and stays comfortable all day, these are a great value. Go for the boxer briefs if you want more coverage or plan to sweat in them, but for regular daily wear, these hit the mark perfectly.

Soft, lightweight, and comfortable
Color: Black,navy,burgundy,brown, Size: Medium
These briefs are soft, lightweight, and very comfortable for everyday wear. The modal microfiber material has a nice silky feel, and they provide plenty of room without feeling bulky. The fit is true to size, which is always a plus when ordering underwear online. Overall, a comfortable and well-made option if you want something soft and easy to wear all day.

Comfortable and soft
Color: Black, Size: Small
I purchased these in small. I have a 30-inch waist, and the small is loose on me. They are described as handmade, and to expect some variance, but there is a noticeable difference between individual items. Individually, they are well constructed, just inconsistent in size.

Just buy them
Color: Black,navy,burgundy,brown, Size: Small
Used to wear sliders all the time, figured i'd switch it up. These are super comfortable, probably the best material underwear I own. Great to just lounge around it or wear everyday. Fit is really good, I got a small and about 29-30" waist. Good bang for your buck too. I've washed them a handful of times and they hold up great, fit great and dont' shrink.

Good underwear. Husband likes them.
Color: Black, Size: Large
Husband wears XL and XL fit well. This is the second pack I got for him. They are decent quality, look and feel nice, not baggy yet not too tight anywhere. They are somewhat thin (but still supportive) and do not make him sweat more so he loves that. No problems washing (they didn’t shrink). Will continue to repurchase these.
