BrickSmart Technic Lamborghini Sián FKP 37 (42115) — 3,696-piece 1:8 scale supercar
★★★★★ Rated 4.9/5 · from 2,880 Verified Reviews

Technic Lamborghini Sián FKP 37 (42115)

Lime green over gold rims — 3,696 pieces at 1:8 scale. Pull the lever under the chassis and the scissor doors swing up the way only a Lamborghini’s do. Flick the switch hidden in the cabin and the rear spoiler deploys. Open the rear hood and a V12 sits there with pistons that pump as the car rolls, driven through an 8-speed sequential box you shift on real paddles. Four-wheel drive, working suspension, disc brakes — and not one sticker in the box; every graphic is printed. The same build, spec for spec, without the badge.

Keep loving Lego. Always.

Nobody here will tell you their bricks aren't excellent — we're builders too, and the shelves behind us prove it. The brick was never the problem. The price was. The brick patent expired in the 1970s: at brand price you're paying for the licence, the retail markup and the marketing — not the plastic. We make the same brick, to the same tolerance, and skip the badge.

Why the price looks too good

Same Bricks. Same Build.
A Fraction of the Price.

Nobody explains this on the shelf tag — so here it is, in plain words.

1

The brick patent expired in the 1970s. Anyone is allowed to make the brick, to the exact same dimensions. That part isn't a secret — it's law.

2

At $449.99, you’re paying for everything except the bricks. The licence, the brand, the retail markup, the marketing. The plastic is the cheapest thing in the box.

3

We make the same brick, to the same tolerance — and skip the badge. Tight clutch, crisp color, fully compatible with every brick you already own.

4

Then a person on our team opens, counts and re-seals every box. Numbered bags, a clear illustrated guide, and a hand-checked piece count before it ever ships.

Lamborghini Sián FKP 37 (42115) — the finished display build
Why the bargain-bin alternatives failed you: they cut the plastic, not the badge. Soft clutch, mystery bags, missing pieces, no one to call. We cut the badge and kept the brick — that's the whole difference, and it's why the trust checklist below exists.

What Builders Report, Hour by Hour

Screen-free hours, honestly counted:

Hour 1

Numbered bags out, zero sorting — the chassis and four-wheel-drive layout go down first, gearbox housing included.

Hour 7

The V12 and the 8-speed box come together. Roll the car and twelve pistons pump; pull a paddle and the gears change. The scissor-door lever goes in around here too, and you will test it about forty times.

Hour 15

Lime panels on, gold rims pressed home, spoiler switch wired up. 23 inches of Sián — finished, displayed, yours.

*Based on customer accounts. Build times vary with pace and coffee supply.

The people behind the boxes

Checked by hand before it ships

“
Every set that leaves our warehouse gets opened, counted and re-sealed by a person on my team. I started BrickSmart after one too many $80 boxes with loose bricks and missing pieces — so if a set isn't good enough for my own shelf, it doesn't go in the box.

The door lever is addictive

One little lever under the chassis and both scissor doors rise together. Smooth, no sticking, no sag afterwards. I've owned three of these 1:8 cars and this is the best door mechanism of the lot.

That green is loud in the best way

It's the whole point of a Sián and they got it right — proper lime, and the gold rims actually look gold rather than mustard. He put it on the mantelpiece the same night.

Printed parts, no stickers

This is the tell for a serious set and it's all printed here. No peeling, no crooked application, no ruined afternoon. Twelve pistons all run smoothly off the drivetrain too.

Spoiler switch is nicely hidden

Took me a minute to find it in the cabin, which is exactly right. Deploys and retracts cleanly. Only note is that at 23 inches it's longer than people expect — measure the shelf.

Six numbered boxes made it painless

The build is split into stages and each one feels like a finish line. I'd never done Technic and never got lost. The manual reads more like a book than instructions.

Wall mount suits this one especially

From above you see the whole engine deck and the stripes down the middle. Looks like a framed print of a car. Hung it in the office and it gets commented on every week.

Frequently Asked Questions

No — and we say it plainly. BrickSmart is an independent brand. The brick patent expired in the 1970s, so we build our bricks to the same dimensions and the same tight tolerance, fully compatible with every brick you already own. What you're not paying for is the badge — that's the entire price difference.
Yes. Clutch power — how firmly bricks grip — is the whole game, and it's the first thing we test. Tight-tolerance molds, crisp color, and a finished model that stays rock-solid on the shelf for years. If any of that isn't true of your set, the 30-day guarantee applies, no questions asked.
This is the fear we built the company around. A person on our team opens, counts and re-seals every box before it ships — that's the hand-check. If anything is still short, we ship you the part or refund you in full. You will never be left mid-build with no one to call.
Most builders finish the car in 12–18 relaxing, screen-free hours. It arrives split into numbered build stages, so there's a natural stopping point every couple of hours rather than one long slog.
3,696 pieces in numbered bags — the full 1:8 chassis with four-wheel drive, the 8-speed sequential gearbox and paddle shifters, the V12, the scissor-door lever, the active rear spoiler switch, working suspension, steering and disc brakes, the lime bodywork with gold rims, and a complete illustrated guide.
There's a lever built into the underside of the car. Push it and a linkage lifts both doors up and forward in the Lamborghini way — purely mechanical, no motors, and they hold their position rather than drooping.
No — every graphic element is printed directly onto the part, exactly as on the original. That's the detail that separates a premium set from a cheap one: nothing to peel, nothing to apply crooked, nothing that lifts at the corners in two years.
Our studs don’t carry a logo, and the serial number under the front hood is unique to your set but it isn’t a Lego serial, so it won’t unlock their online certificates. Everything else — the 3,696 pieces, the gearbox, the V12, the doors, the spoiler, the four-wheel drive, the printed graphics — is matched to the original’s published spec. If you're buying sealed boxes as investments, buy an original. If you're building the car for your shelf, this is the same build.
Every order gets 5–7 business day shipping from our US warehouse, with tracking. No four-week overseas wait, no customs surprises — the box is already in the country.
