Excellent service from MX5 parts as usual delivered very quickly.
Lifters are decent bit of kit, look the part and operate as expected. Overall I am happy with them. A few comments though.
Some of the powder coating on one bottom bracket had chipped off. Since the 'chip' was not in the plastic bag I assume this happened in the factory so they need to up their QC.
The screw thread holding the ball joint to the bottom bracket extends too far behind the bracket and fouls the bodywork. A couple of minutes with a dremel cutting disc cured the problem but it was an annoyance.
Finally several reviews mention the plastic fittings used to secure one end of the bracket to the body. I agree a metal fixing would inspire more confidence but the fixings I got seemed well up to the job and fitted very securely, perhaps they have been updated.
