My view on weitec vs jom as ive had both
Joms: corrode quite easily if not looked after, ALOT CHEAPER THAN WEITECS, softer/bouncier ride than W's and no tab for r32 arb
Weitecs: again corrode badly if not looked after, expensive, very harsh ride, does have tab for arb, and dont look cheap like the joms
My personal opinion is that i wasted £400 on them when my joms were perfectly fine !
Go for joms you get a lengthy warranty just make sure you grease the ballbags out of them
