Hello Ray,
Re tyres and harsh ride:- I think that the ride with any 35 profile tyre on a car built with sports suspension is going to be ‘harsh’ irrespective of brand - you just don’t have sufficient shock absorbing rubber to benefit from comfort. Moving to 17 inch wheels will allow higher profile and help to some extent. Other considerations:- have you checked whether the current tyres are XL? - or run-flat. Either of these will add to ride harshness.
Non- folding mirrors:- worth obtaining a build record from a main dealer via. the VIN. This will tell you whether the car was built with folding mirrors, but are no longer working. It has been said that VAG equip all their vehicles with such motorised mirrors ( your age of car?) and all you need to do is to have them coded to operate. This is new to me and would be great. I’m not having that confirmed with our non-Audi, but….
Kind regards,
Gareth.
