What make are your +20 thou 3.5 and 3.9 litre pistons?
All the plus 20 pistons we have are manufactured for ourselves. They have been what we have used for the past 15 years in our engines as well as our customers engines. We have never had any problems as you would imagine as we are very strict with our quality control.
Rover pistons will cost more than double our prices and specialist forged pistons are more than £800 a set.
