Replacing old stock shocks

[Waylander80]

Hi iam pretty new to audi having mostly been a jap car (evo) driver. Needed something less brrrr lol.

Both front right And rear left active suspension has gone and iam thinking of putting coilovers on. I have choice of eibach or blistein and i was wondering whats people thoughts on them both and how easy was the install. Last time idid this i was alot younger and i promised never to lower another car.

CArs on 20” rims and i just dont have the cash to replace £3200 worth of audi parts hence going for the cheaper option of coilovers.

Any advice is welcome.
