Maxpeedingrods (you'll also see it written maXpeedingrods, or just MXR) sells aftermarket performance parts for people who work on their own cars. It says it has been at it since 2006, and the catalog is enormous: coilover suspension kits, forged connecting rods, turbochargers and turbo cartridges, air suspension, control arms and engine parts, plus a sideline in diesel air heaters, inverter generators and workshop tools. The US site is run by Hong Kong Ruisu Trading Co., Ltd and prices everything in US dollars.

It suits DIY tuners and project-car owners who know their part numbers, or who are happy to work through the vehicle selector and read the fitment notes on each listing. Most parts are listed for specific makes, models and years, so it's worth checking before you order. Items held in its US warehouse ship free within the US and usually arrive in 3 to 7 business days. Some parts ship from Hong Kong instead: those take 7 to 25 business days and any import duties are yours to pay. Each product page tells you which applies.

What's worth a look

Here are six products from across the range, with the prices shown on the US site today.

The forged H-beam rod set for the NB Mazda MX-5 Miata is currently $374.99 instead of $457.00, and the adjustable coilover kit for 1992 to 2000 Honda Civics is $399.99, down from $471.00. Both are in stock in the US. The GT3071-style racing turbo, by contrast, ships from Hong Kong, so allow for the longer wait and possible duties. If you're not here for the car, the 8000W diesel air heater ($129.00) and the 2400W inverter generator ($399.99) are both stocked in the US and ship free.

How to save more

• Work out which code is worth most for your basket. On a $400 coilover kit, 8% off with co8 is about $32, more than ALL20 but slightly less than ALL30. Try the likely codes at checkout to see which saves most.
• Stick to US-stocked parts where you can. You get free shipping and a 3 to 7 day wait, and you avoid the duties that can come with Hong Kong shipments.
• Get the fitment right first. Change-of-mind returns are accepted within 30 days, but you pay return postage and a restocking fee, so ask support before ordering if a listing isn't clear.
