Mike,
M-parallels changes the way the car drive even more so that its looks. Believe me, I used to have BBS-RK 18 in my '89 sedan. Then I switched to M-Parallel replica 17 inchers. The M-pars are great with sticky tires like S02. I had Eiback Prokits and bilstein sports shocks.
When I put these into my newer green Touring, that touring really drives well and corners the way I wanted without tires screeching like there is no tomorrow.
My sedan had the Touring basket-weaves like yours and even with a complete set of new tires, feels like a boat now. I am not tracking my sedan anymore but using the Touring more. Take a look at the difference here:
