Many thanks Evy showed me an article of them in Total KitCar Mag smone time ago, sounds perfect solution for us

Seems to offer reprofile cam option for £226.78 far cheaper than Piper or Kent cams at £375. On Piper website offers 3 Fast Road cam, Ultimate Road, Rally and Race cam, which is most similar to SS4 from Shawspeed, i would like to see power graph as power band on Piper is high 3000rpm to 7500rpm 8200rpm and 8500rpm. What would these be like to drive normal and in race, I hope these would be reliable in race condition too?
