Dwight and his team have engineered the very best cylinder heads for me - no one comes close - Thanks Dwight!

To Whom It may concern My wheel was cracked due to driving over a bump at high speed, Unsure of what or who to use I googled Aliminum Welding and Leading Edge Cylinder Heads popped up and sent an email to not only Dwight but a few different companies, Not only was Dwight the first customer to reply but was the best price and the shortest time frame available as to getting it fixed. I explained that my car was off the road and he had it completed within 2 hours. Not only was I very impressed with his service but the tyre shop I went through ( Haslips Tyres) also commented to me about the quality of the job confirming that it was outstanding. I recommend Dwight at Leading Edge Cylinder Heads to everyone and will be passing on my good experience to everyone i know needing a great service, Thanks again Dwight , Much Appreciated Aaron Martin Aaron Martin

I can't recommend Dwight's services highly enough. His work is second to none. As part of Team Farnell Racing, Leading Edge Cylinder Heads has kept us at the top of the field winning numerous North Island and National titles for PWC (jetski) racing. Both short course and endurance racing.
