Frequently Asked Questions

General

How do I know if a part fits my vehicle?
Check the product compatibility section on each listing. You can also contact our team with your VIN number for confirmation.
Can I install these parts myself?
Many parts can be installed by experienced DIY enthusiasts. However, we recommend professional installation for complex components like turbochargers and suspension systems.
Are aftermarket parts reliable?
We only stock reputable brands with proven track records. Many aftermarket parts offer superior performance and durability compared to OEM components.
Do performance parts affect my warranty?
Modifications may affect your manufacturer warranty. Check with your dealer before installation. Our parts come with their own manufacturer warranties.

Performance

Will this increase horsepower?
Power gains vary by part and vehicle. Check individual product descriptions for estimated performance improvements.
Do I need ECU tuning?
Major modifications like turbo upgrades typically require ECU tuning to maximize performance and ensure reliability.
Which upgrade gives the biggest performance gain?
ECU tuning and turbo upgrades typically provide the most significant power increases. However, a balanced approach with supporting mods is recommended.
Can I mix different performance brands?
Yes, but ensure compatibility. Some systems work best when components are from the same manufacturer.

Wheels & Suspension

What wheel size should I choose?
Consider your vehicle's specifications, intended use, and local regulations. Larger wheels improve aesthetics but may affect ride quality.
Will lowering affect ride quality?
Lowering typically results in a firmer ride. Quality coilovers offer adjustability to balance comfort and performance.
Are coilovers better than lowering springs?
Coilovers offer more adjustability and better performance but cost more. Lowering springs are a budget-friendly option for stance improvement.
How often should suspension be serviced?
Inspect suspension components every 20,000 km or annually. Coilovers may need rebuilding every 50,000-100,000 km depending on use.

Brakes

When should brake pads be replaced?
Replace pads when they reach 3mm thickness or if you hear squealing. Performance pads may wear faster but offer better stopping power.
Are drilled or slotted rotors better?
Slotted rotors are better for track use. Drilled rotors look great and work well for street driving. Drilled and slotted offer both benefits.
Do performance brakes require bedding in?
Yes, proper bedding-in is essential for optimal performance. Follow the manufacturer's break-in procedure carefully.

Shipping

How long does delivery take?
Domestic orders typically arrive within 3-7 business days. International shipping times vary by destination.
Can I track my order?
Yes, you'll receive a tracking number via email once your order ships. Track your package through our website or the courier's site.
Do you ship internationally?
Yes, we ship to select international markets. Shipping costs and delivery times vary by location. Contact us for specific details.

Returns

Can I return a part if it doesn't fit?
Yes, unused parts in original packaging can be returned within 30 days. Some items may be subject to a restocking fee.
What if my item arrives damaged?
Contact us immediately with photos of the damage. We'll arrange a replacement or refund at no cost to you.
How do warranty claims work?
Contact us with your order number and issue description. We'll coordinate with the manufacturer to process your warranty claim.
