Ok, the second thing actually, those pig awful wind deflectors were the first 
Anyhow, welcome back to the fold Andrew and congrats on the new purchase. We’ll all look forward to the car’s progress, warts and all. A good choice of project car for the channel and a very nice thing to own for your own pleasure.
I’m assuming the change from perfectly good (understatement) PS4S to Goodyears is a sponsorship thing?
Personally I’d much rather keep the Michelins on as they make the car look more original, even though they’re not strictly original if that makes sense.
Here’s looking forward to the next instalment…
Wind deflectors are gone already, they were on the car in some 2019 pics when it had done 6k miles. I know they are marmite, recently watched a video of a Mk4 R32 driving through 'that' ford way too fast and killing his engine, guess what, wind deflectors!
I'm not sponsored by anyone. When I had my first CSS, because of originality and how the Cup 2s contributed to all the reviews, I was reluctant to take them off and in the 4 years since I sold it I realised they had hampered my enjoyment of it - obvious really - as they are track tyres and I drove it solely on the road.
So originality in the tyres isn't really something I am bothered about. When I got my GTI TCR, the owner had ditched the Cup 2s and fitted Goodyear Asymmetric 5s on 18s and I was commuting 50 fast miles per day in all weathers and I grew to have a lot of respect for them. Then a year later my brand new Mk8 Clubsport arrived on 18" F1 Supersports as that tyre had now been homologated for the GTI (making it more "original" on a GTI than a 4S). Ran them for a month/1000 miles before swapping to Asymmetric 5s, then all season tyres and back onto Supersports before it was sold and I realised they contributed a lot to the car's dynamic superiority over Mk7/7.5 as it drove way better on them than the highly rated Asymmetric 5s.
Why ditch perfectly good 4S though? I needed some high performance road tyres for my (now sold) Leon Cupra as I only had semi-slicks for it. So rather than fit new brand ones to that, it inherited the PS4S and my CSS got the Supersports which is my preferred tyre from personal experience.
I wouldn't be blindly led by reviews, my decision is based on experience, but Supersports beat PS4S in this recent evo review which used a Mk8 Clubsport for testing;
