Yes, initially when I did the 5lug conversion I was running around on late model e36 M3 DS2 wheels, 17x8.5 rear, 17x7.5 front with 245/225 respectively. I felt it handled horrible.
To be perfectly honest it was bad enough I felt it was just plain unsafe, and I'm not even talking about pushing the car.. one distict memotry was trying to make a uturn at 20mph with 6 lanes to do it... scrubbing the entire way. I changed that out as soon as I could to 8.5 DS2's all around with 255 rear and 245 front. This was worlds better but still had a mild understeer.
Once I switched to 245 all around on the CSL's the car was perfect.
Every e30 I've ever driven with staggered rubber handled the same with horrible understeer.
