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).
