Excellent communication super fast shipping thank you
Excellent product, well made and easy to fit, excellent professional service from ATR
Great product well built fits like a dream
Fits well, looks good. Needs a option with hose to suit. Didn't fix my heavy pedal after asking about different size bore options with twin plate clutch setup.
First of all good service, my part was well packaged. Care was taken to make sure it arrived to me in good order not like other companies I’ve ordered from inthe past where things were damaged and they didn’t even and they tried to blame me! The pedal fit beautifully. I will use again in the future. Being Aussie made is even better Thankyou
