Trying to learn as much as I can about the suspension system in my car, want to know the names of all the parts and how they work BEFORE I buy them. It's hard because a lot of what I'm finding assumes that the reader already is knowledgeable about automotive systems. My goal: weekend cruiser, no racing but lowered and better handling than stock. So far I've managed to get a few used parts: H&R Super Sport Springs Steeda bumpsteer kit Maximum Motorsports Caster Camber Plates Blistien Struts â€“ used from a '03 Cobra 35k So, here's my shopping list of possible parts from MM: [TABLE="width: 332"] [TR] [TD][/TD] [/TR] [TR] [TD]Steering Rack Bushings, Solid, 1985-04 Mustang with stock k-member[/TD] [/TR] [TR] [TD]Urethane front spring isolators, 1984-04 Mustang[/TD] [/TR] [TR] [TD]Urethane rear spring isolators, 1979-04 Mustang[/TD] [/TR] [TR] [TD]Swaybar Bushing, 30 mm[/TD] [/TR] [TR] [TD]Urethane Bushing kit for HD RLCA's, 1979-98[/TD] [/TR] [TR] [TD]12mm hardware kit for RLCA mounting, 1979-98 Mustang[/TD] [/TR] [TR] [TD]Heavy-Duty Mustang Rear Lower Control Arms, 1979-98[/TD] [/TR] [TR] [TD]Ford Mustang Rear Upper Control Arms, solid axle, 1979-04[/TD] [/TR] [TR] [TD]1987-04 Bilstein HD series shock (24-064187)[/TD] [/TR] [/TABLE] I'm still a bit confused about ball joints - I know there are upper and lower, but are they only on the front end? I read that replacing the front control arms with OEM 03/04 Cobra arms is a good improvement. If I manage to find a pair, how many ball joints, and what kind, do I need? Thanks in advance for any info and advice!
