Porsche Motorsports uses SRF and I use it on my Cup. Worth the money. It lasts an entire season. Gofish I have driven your car after it was all setup. It's perfect.

 

All I'm doing is installing new Pads RS14 from Paul ( and I guess removings spiders, springs & any shims) puttin speedbleeders in (Just arrived- now they know proper fitting !) Motul 600 fluid and Cup Car Ducts. And more polish!!
