I will post up once i get the correct struts, i went for theone to mod the mk5 golf, as posted above. They are 60mm shorter than the standard leon ones though, so they arent any use for us! Boot is too low and serious head hitter!!
Also, for our cars, i bought all the items (struts, buffers, and ball pins) but all we need for the leon is the struts. I thought the standard spring loaded Leon ones were better for giving it a push! I will find out like i say.
If any one wants to try and find some gas struts, they need to be:
Total length 500mm
Body of strut: 280mm ish
Stroke: 210mm
And you are looking for a force of 600NM
(550 may do the trick, 600nm seem to be very hard to shut the boot, although this is said to become easier with use).
I can only browse on my phone as im working away, so i cant really search around. Ive emailed one strut specialist who make the to your requeirments.
