・HKS has set the MAX IV for both sportiness and comfort.
・We haven’t spoiled stock’s sportiness and improved the comfortable drive and also provides better control.
・We have improved the driving experience drastically compared to the old model by analyzing year 2012 model and VPS and new piston.
・We have improved driving performance of road-hugging property by high-rate + helper-spring. And improving the start-up damping allow comfortable drive and keep down the sudden pressure change.
・Set about 20th step for a comfort drive and about 5th step for a fast drive.
・If the length of case shortens below the lower limit value, it is likely to interfere with the upper arm and body. Also depend on the size of the tire wheel, it could interfere with fender even within the limits.

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions.
