Check fitment.
Skip the regrets.
Most mod regrets come down to three things: a part that doesn't fit, a total that crept up, and a build you'd do differently. SpekForge puts all three in front of you before you spend.
// fitment check
Check the fit
before you buy.
SpekForge checks parts against your exact vehicle. Parts that won't fit are marked NO FIT, and the add button turns into "Doesn't fit". Fitment is a guide, so confirm with the retailer before you buy.
- NO FIT badges on parts that won't fit your car
- Parts that fit add straight to your build, with a running total up top
- Checked against the vehicle you pick, by VIN or by year, make and model
// the cart

See the total.
Every part you plan lands in one cart for your exact car, with its price, your build total and an estimated horsepower gain.
- Build total and estimated horsepower gain at a glance
- A shop link on every part — eBay is live today, more retailers are on the way
- Affiliate links are always disclosed

// set up your car
1. Start with your VIN
Decode a 17-character VIN to auto-fill your vehicle, or pick the year, make and model by hand.
2. Pick the make
Choose from the makes SpekForge supports.
3. Pick the model
Choose your model and confirm the vehicle. That is the car everything else is checked against.
