Every marque has its productive mods and those that may have
cool factor but don't improve and maybe actually hurt handling.
Focus here is the basic through more advanced mods for a street car.
I'm holding mods to performance increases with minimal impact
on the comfort of driving the car. Track level/ Autocross is beyond
the intended scope.
Primary upgrades: (Tighten up the car and make more reliable.)
1. Reinforced Upper Rear shock mounts.
2. Solid Rubber (M3) front bushings.
3. Non rubber mounted front Ball Joints.
4. Reinforce Rear Sway bar tabs.
5. Sway bar bushings front and rear.
Secondary Upgrades. (Stiffen the chassis a bit)
1. X-brace
2. Front strut tower brace.
3. Rear undercarrage brace.
4. Tranny and Differential Bushing upgrade.
5. Firm subframe bushings.
(Whats the best material? Delrin? Urathane?) Finishing touches: (Take advantage of the chassis improvements.)
1. Heavier sway bars.
2. Full shock & strut set.
(Koni or Bilstien) 3. Street sport Spring kit.
(Coil over or Just springs...Hmm?) 4. Camber kit if lowering springs are installed.
5. + size tires and wheels.
Any others?
I flagged things with colored comments that I'm firuring out....
I place the strut brace a bit higher because I've found that a
lot of different track cars show fatigue signs in areas that are likely
due to strut tower flex. IE Leaky Windshields, seams that leak, and I
give it a bump for the cool factor cause you can see it when you work
on the car...
