The Track Moved. Your Car Didn't.

Your Mini-Z felt great at seven and terrible by nine. The car didn't change. The grip did, and tearing it apart is the wrong response.

The New Guy's Second Night Is the One That Matters

Clubs are great at welcoming a first-timer and terrible at what comes after. Retention isn't decided on night one, it's decided on night two.

Sandbagging Is Just Fear Dressed Up As Strategy

Holding back pace to stay in a favorable class feels like smart racing. It's actually the same avoidance as never upgrading at all.

Nobody Remembers Your Bad Heat But You

The fear of looking slow in front of your club costs more lap time than any setup mistake, and the audience you are protecting yourself from does not exist.

Bearings

Fast Eddy Sealed Bearing Kit (MR-03)

Sealed bearings for the MR-03. What I run on mine. Drop-in replacement, sealed so they do not grit up.

Tires (Front)

PN Racing Mini-Z Slick Tires (Front)

What I run up front. Slicks give a cleaner bite off the carpet than the stock radials once tire prep is dialed in. PN Racing lists every compound and width by SKU on its own page; Kenon Hobby is their worldwide distributor.

Tires (Rear)

PN Racing Mini-Z Radial Tires (Rear)

What I run out back. Radials give forgiving rotation without breaking loose under power. PN Racing lists every compound and width by SKU on its own page; Kenon Hobby is their worldwide distributor.

T-Plate

Kyosho MZW404S Carbon Rear Suspension Plate

The Kyosho-branded carbon T-plate I run on the MR-03. Consistent flex, durable, fits the stock geometry without drama.

Body

Raybrig NSX Auto Scale Body

The Raybrig NSX is one of two bodies I run. Clean Super GT livery, looks right on an RCP track, wears predictably. Verify wheelbase before ordering.

Batteries

EBL 1100mAh AAA NiMH Rechargeable (6-pack)

What I actually run. 1100mAh AAA gives more runtime per charge than Eneloop at a lower price. Rotate two sets and they last forever.

Charger

ISDT N8 Smart Battery Charger (8-bay)

What sits on my bench. 8 bays means a full fleet charges at once, LCD shows individual cell state. Overkill for one car, perfect once you have a pit bag.

Tools

Stedi Model Nipper (Flush Cutter)

Ultra-thin sprue cutter. What I use for king pin flips, body mount trim, and anything that needs a clean cut instead of a crushed one. For files and rougher stuff, Harbor Freight works fine.
