Complete fitting kit: side mounts included. This frame comes with its own side mounts, so any side mount bucket seat bolts straight to it. You only need the seat and the frame, with no separate side mounts to buy. The slider is built in as well, so no separate runner kit is needed.
A PCI Racing sliding sub frame for the Porsche Boxster 987. Part number SM-987-S1.
The 987 is the second generation Boxster. The 986 before it takes a different mount, so check the generation code before you order and send us the registration if you are unsure.
The slider
The seat moves fore and aft after installation. PCI’s S1 slider bolts to the base with four bolts where a conventional slider uses two, which they describe as twice as strong as two bolt mounting.
In a Boxster the slider is usually worth having, because most of these are still road cars and being able to move the seat back matters when somebody else drives or when you are getting things in and out of a small cabin.
Head clearance
This is the thing to think about before you choose a seat. A 987 is low, and with a helmet and a roll bar or harness bar in the car the vertical space runs out before the legroom does. A purpose made mount gets you down where a fabricated bracket usually will not.
Construction
Laser cut and CNC formed from a single piece of 1/8 inch carbon steel, gloss black powder coat, grade 10.9 8mm hardware, five and six point sub belt mounting locations built in.
Ordering
Side mount, for a competition bucket, on the factory seat mounting points. Handed, order twice for a pair.
Keep the original seats. On a Porsche they are part of the value.
