Spurrills Sensitivity In the Omega

Hello, some time ago I asked the question about a rim size. This was also answered well. Now I thought about the Spurrillensensitivity. My old Omega bj. ’95 was true to the mark with a standard size of 195/65 R15 V. The tires were from Conti I never had any problems with it. Now I bought another Omega only bj. ’99 with 225/55 R16 V the standard size in the sport version. Tires Pirelli P7 and the car is so nice… bad z u he wants to go most of the time where I don’t want to go. He’s so sensitive already had new crossbars set the track again, but it doesn’t really get better. I mean having it adjusted after the track was better, but the new crossbars didn’t do anything. The old ones weren’t recognisably knocked out or pinned. I changed them to go safely. Manufacturer Febi Bilstein thus no cheap product. Can the tires come from a lot of control? Nothing has been changed on the chassis for the previous year of construction. This is actually one of the decisive reasons why I would like to get 17 or 18 inches. Also to improve the driving behaviour. Unfortunately, there are still no HD or PU cans and since it will never exist…
