I wasn't sure who to go to for having my Werks B5 sleeve pinched since there were several on the internet. Read about rayaracing so gave him a try. I'm totally happy with his work and my engine runs and sounds as good as new. Now I know when the sleeve is worn. Highly recommend rayaracing to anyone looking for a great sleeve pinching service. He's always answered my calls and questions and for the quality workmanship and price - better than buying a new engine.
