Gruppe- Am looking at a very clean and tidy '88 535iA here in SoCal. Needs wheels and tires, as still shod with worn out TRX's, but have questions for group intelligence apropos the rest of the suspension. Primarily need to know the best spring/bar and shock setups to look at to upgrade the handling a bit while maintaining sufficient ride height so as not to bottom out on every dip and keep a sensibly comfortable ride. A performance-street package is what I seek--and looking for suggestions and prior experience from you all to help me out. TIA- Peter
