Hmm good points already given. I would go there when its silent time (autumn, early spring) to have less worry of other drivers and enjoy the time more. Don't know the A2 platform that well that could give any spesifics, but driving vise good to drive with a safe speeds to avoid any accidents.
It's just nuts and bolts in real terms, but effectively you are assembling two new front strut assemblies as you need to remove the existing hub casting from the shock/spring and fit the new hub/ brake / caliper and a new disc. Maybe possible without needing spring compressors etc, but if you're looking at the Ring are springs / shocks / brake pipes (at least) not also on the menu? When my mechanic made up my existing big brake system I dropped off the pile of parts (top strut bearings, SP3248 springs, B6 shocks, Polo GTI hubs, 312mm carrier-calipers-pads, HEL braided brake pipes, Febi drop link / ARB bush kit, Blueprint (Febi) discs), the weekend before and he put them all together, then dropped the existing entire strut / caliper combo on either side and put the new ones in when he had a workshop space a few days later. As the replaced struts had been new but standard parts (B4 shocks, Monroe SP3248 springs, similar Febi Bilstein parts throughout a few months previously) they were swapped across onto my project car where the original brake calipers and drums had been sprayed in a 'sporty" colour at some point, but the discs, pads, shocks, springs, ARB/ and strut bearings were all needing to be replaced so a quick refresh.
