I received the products today.
I thought it would take time to arrive in Japan, but it was super faster than I expected.
Thank you so much!!
We are really happy with these engines.
Your service, product, speed, everything was perfect!

We had a Triumph spitfire cam reground to a 270 profile. After my initial mistake with ordering, Piper did a great job sorting it and getting the job done. Cam is back ready to go in the engine for the summer.

Excellent supplier of performance parts, competition parts are of very good quality. I bought a vvc conversion kit for lotus elise, this company is the only one to supply the full conversion material. online customer service is very professional and responds quickly to requests for help. so it’s 10/10.

Seb Zowa

Best supplier of cams and exhausts, 100% recommend to anyone!

Steve Smith

Just wanted to thank the team for the excellent service that I experienced recently during my purchase. I dealt with a member of the sales team, who was a pleasure to deal with and gave excellent customer service with a high level of knowledge about the product I was buying. Overall I am very impressed and will most definitely be back to purchase again!
