had an initial issue with leaky shock tops on a customers car we built. did them up as tight as poss by hand and issue went away and hasnt returned since so think the thread just needs to be used/abused to tighten a touch and is fine.
also have just fitted the alloy shock caps to my own car and tested them at worksop on sunday. is a nice fibre/rubber style washer for inside the top of the shocktop so problem solved. fit and quality is typical xray (awsome)
will soon be in stock with us
