Kelford 264/260 Camshaft Set - Subaru EJ20 AVCS - WRX STI (GD)
The Kelford V2-199-B is a four-cam set for the Subaru EJ20 with intake AVCS, the engine in the WRX STI (GD), which Kelford lists as Version 7 to 10. It is Kelford's high-lift, short-duration race and rally grind: 264° on the intake and 260° on the exhaust, with 10.70mm and 10.20mm of valve lift. That combination gives sharp throttle response and stronger mid-range power, and Kelford matches it to turbos of around 54-60mm.

Kelford Cams: choosing the right camshaft, and how to identify Subaru EJ cams.
The lobes sweep wider across the bucket than the factory cams, so this set must run on shimless buckets (or buckets with the shim underneath). It will not work with the early buckets that carry the shim on top.
Check your intake cams before ordering: this set suits engines with four paddle-style triggers on the back of the intake cams (second photo). Engines with the slot-style trigger (third photo) need Kelford's R-199 range instead.
Note: Needs shimless buckets, and the ECU must be tuned to suit. Kelford recommends upgraded valve springs; its own match for this grind is the KVS1847-BT beehive kit. Installation by a professional is recommended.
