About Us

Precision Matters was started by Ron LaDow in 2000 with the purpose of creating innovative, quality components to preserve and improve enthusiasts' automobiles.

Ron's background in product development engineering and a lifelong love affair with classic, performance automobiles come together to create an idea factory that will offer 356, 912 and 911 owners the most imaginative and functional new products to improve performance and reliability.

In the Spring of 2015, Precision Matters acquired the business assets of Mainely Custom by Design, a company offering similar products of high quality. By Autumn, 2015, most of the products had been integrated into Precision Matters' line, some already having been improved. We are proud to offer them.

Some notes on our business practices:

We are open 8AM to 5PM weekdays (West Coast time) and most often Saturday mornings.

With improvment in the software, we now feature web-commerce for most of our products; please read the descriptions or call us to make sure the part will fit your car.

Like most suppliers of small-market products, we strive to keep our shipping costs to the customer as low as possible; money spent with a shipper is money not spent on our products. Toward that end, we commonly use UPS and our volume is such that we were recently able to negotiate a greater discount rate. We do use US Postal Services for those products which can go first-class in an envelope. The 'flat-rate' box offerings have seen increases in costs which, coupled with our new UPS rates make them not worth the risk.

We accept returns without question for 30 days after purchase for un-used parts with a 5% restock fee. If the return is a result of a Precision Matters mistake, there is no restock fee and shipping charges will be reversed. We do not accept returns on tools other than replacement for faulty items.

Our products are under constant development driven by customer feedback and are therefore made in relatively small runs to avoid stocking 'obsolete' parts. As a result, specification and pricing are subject to change without notice.

We offer discounts to resellers on resalable parts, favoring quantity purchases; please call for details and a price schedule. Most tools are not included in the program.
