I'd put my trust in a certified CGT tech at a Porsche dealership. Rennlist forum - CGT section would be a great place to find one in your area. All the best, CGT is one amazing car! I regretfully sold one 2 years ago, While I really liked everything about it especially the noise it makes! my only dislike was how low the front sits, for local driving a lift system would've been nice, almost impossible not to scrape under the nose.
