does it make sense to build D-top pistons in my soon-to-be fast road standard pre-A+ 998? I could get 4 D-top for about £100 which look quite OK.
I plan to build a slightly modified 998 with a 12g295 which is original and I do not really want to skim.
Is it even possible? Can I just build my dished pistons and put the Cooper ones plug-and-play in my engine?
I know the bore and stroke are the same, but I have no idea concerning the axle height of both pistons and the CR which is going to be reached in doing that.
