Frequently Asked Questions

What's the difference between 200TW and max-performance summer tires?

200-treadwear (200TW) tires are extreme-performance track and autocross rubber: maximum dry grip that gives up tread life, wet traction, and refinement. Max-performance summer tires trade a little ultimate bite for a usable street tire that's quieter, better in the rain, and longer-lasting. Choose 200TW if you run timed events and don't mind replacing them; choose max-performance summer for spirited street and canyon driving.

How often should I change the oil in a tuned Japanese performance car?

Tuned engines benefit from frequent oil changes. For street-driven modified cars: every 3,000-5,000 miles. For track-driven cars: every 2,000-3,000 miles. For drag-raced cars: after every competition. Use OEM-recommended grade or better synthetic oil. Rotary engines require even more frequent changes (every 3,000 miles maximum).

Found the car. Understand the handover.

Before making promises about collection, coordinate the inspection, paperwork, seller release and transport. Give each part of the purchase its own check.
