My FRS set is set up with the 6kg/mm F and 7kg/mm rear, standard spec valve, and range adjustments, with rubber bushings rather than ball joints at the top.

2. RS-R manufactures and designs the case, piston, valves and all hardware components in-house, and I've visited the manufacturing facilities near Osaka, Japan, so I trust them that much.

3. These are aircraft grade aluminum shell cases and ends, (I forgot that the actual T rating of the alloy). For the FRS set, the suspension coil and shock assembly with mounts, weighed 3lbs less than OEM parts removed to replace (total of all four ends). While the OEM's weight is mainly in the large coil springs, the majority of weight on the RSR Sports-i is in the case shell and valve/piston which seems much more strong than OE internals and shell case.

4. Due to the very long lower arms and steering rack pivots as well as toe-locator rods, the FRS needed minimal correction of 0.4 mm at both ends of the rack-ends, to bring the toe back to where it was originally with OE height, this, at 32mm drop. I'd need to re-check after a few dozen miles to see if any settling of bushings or springs caused any changes, but that's what I see at this time, 1 day after installation.

Yes, I am in Los Angeles/South Bay area and hope to meet you soon for a cup of coffee or snacks~!

The sports-I are 3 pounds less than OEM overall?
