After a couple of gas boot struts for my A3, planning on getting them from eurocarparts but not sure which one i need as there are 2 available. I have a 3-door Sport but i've fitted an S-line spoiler. There's either this one: Audi | Euro Car Parts UKâs No.1 Car Parts Retailer or this one: Audi | Euro Car Parts UKâs No.1 Car Parts Retailer. Does say one is with a spoiler, one without, but considering I fitted a spoiler and it's fine does it matter? Also minimal differences between length and stroke (8mm).
