I have two cars from that era, both on 17' Euromeisters. The coupe has Michelin Pilot Sports which are incredible, and the cabriolet has Continental Extreme Contacts which were a mistake and ride like crap (way too soft and mushy feeling compared to the Pilot Sports). Both are slightly below Euro height and have Koni's. I think the height measurements only work if the car being measured has your exact wheel/tire combo.
I can't answer the ride quality question, I lowered them both immediately after purchase. They never bottom out but will rub in the front on a hard turn up a steep driveway..... but honestly, so will anything cool enough to be worth driving.
