Oh dear! A TCR shaped spanner in the works.
I wonder if the TCR has the same springs as a Clubsport as the CS is definitely choppier than a regular GTI or R (I’ve owned examples of all three). The CS isn’t uncomfortable though, you’re just very aware of the road surface.
At the end of the day harsher springs are just that, no amount of softer damping will disguise it. In fact you need slightly firmer damping to control the undulations more, but it’s always going to be choppy.
My preference is always slightly softer springs and firm dampers which Peugeot used to be very good at.
Oh, FWIW, if it were my money I’d get a standard GTI with maybe Brescias (or just buy spacers or aftermarket 18’s) and climate screen (if the car was kept outside) with no other extras. The things are pretty loaded with extras now anyway and at the end of the model cycle so the less spent on extras is less depreciation.
Then buy black mirror covers.
Or a standard TCR.
Or an R for a few extra quid which is a much better all round car.
