⭐⭐⭐⭐⭐ Alex Reynolds - Car Enthusiast (DIY Garage Modifier)
"Installed the BOTRAK 3mm spacers on my 2008 Smart Fortwo W451 last month, and the difference is instantly noticeable. The wider stance gives it a much more aggressive look without looking overdone. Fitment was perfect—slip-on design made it a breeze with just a torque wrench. No vibrations or wobbling even at highway speeds. The anodized black finish also matches my wheels perfectly and has held up well through rain and city grime."Purchase Date: February 2025 | Usage Period: 2 months
⭐⭐⭐⭐⭐ Jordan Lee - Automotive Customization Shop Technician
"We’ve used these spacers on three Smart Fortwo builds now, and every client has been thrilled. The precision-machined 5x112mm fitment eliminates any wobble, which we’ve occasionally seen with cheaper brands. We especially appreciate the ±0.1mm tolerance—makes alignment checks faster and more reliable. For a shop that values efficiency and quality, these are now our go-to spacers for Smart models."Purchase Date: November 2024 | Usage Period: 5 months
⭐⭐⭐⭐⭐ Daniel Carter - Weekend Track Driver
"I upgraded to the BOTRAK Pro Model (10mm, 7075-T6 aluminum) for my W452 used in autocross events. The increased wheelbase has significantly improved cornering stability and reduced body roll. Even under hard braking and high lateral G-forces, there’s zero sign of spacer flex or wear. The aerospace-grade aluminum feels rock-solid. Worth every penny for performance-focused builds."Purchase Date: September 2024 | Usage Period: 8 months
⭐⭐⭐⭐☆ Mia Johnson - Urban Commuter
"I wanted a slightly wider look for my Smart Fortwo without going overboard. The Base Model 3mm spacers were perfect—subtle but effective. Installation took under 20 minutes, and the anodized coating cleans up easily with just soapy water. Only reason I didn’t give 5 stars is because I wish they offered a silver finish option to match my alloy wheels. Otherwise, excellent product for daily use."Purchase Date: January 2025 | Usage Period: 4 months
⭐⭐⭐⭐⭐ Luca Moretti - European Vehicle Tuner
"We recently used BOTRAK’s custom 8mm spacers for a client’s W450 restomod project. The ability to request non-standard thickness and confirm fitment directly with their engineering team gave us confidence in the build. The reinforced edges and load distribution design passed our vibration tests with flying colors. These aren’t just spacers—they’re engineered components. Highly recommend for serious modification work."Purchase Date: April 2024 | Usage Period: 7 months

David Tran - Senior Product Engineer, Aftermarket Performance Group
"BOTRAK’s approach to wheel spacer design sets a new benchmark. Their use of 6061-T6 and 7075-T6 aluminum, combined with ISO and SAE certifications, ensures both safety and performance. The slip-on design doesn’t compromise structural integrity—a rare achievement in the aftermarket space. I recommend the Advanced or Pro models for any vehicle undergoing performance or aesthetic tuning."
Dr. Elena Petrova - Vehicle Dynamics Specialist
"From a handling perspective, a 3–10mm increase in track width can reduce lateral load transfer by up to 8%, improving grip and stability. BOTRAK’s spacers deliver this benefit without adding unsprung mass, thanks to their lightweight anodized aluminum construction. When installed correctly, they contribute positively to overall vehicle dynamics—especially in small, nimble platforms like the Smart Fortwo."

"Did a group buy for five members. All reported smooth installs and improved appearance. Only note: thicker than 6mm may require longer studs, but BOTRAK provides clear guidance. Solid brand support."
