I got the idea from a post over on Moparts and expanded it some. I thought it might be useful to see what others are doing in the way of making our cars handle better? Mopar owners seem to be more interested in making their cars handle now that there are more parts available than ever before.

Just copy and paste below and fill it in. Include a picture of your car at the bottom!

Needs better rear pads when autocrossing as the fronts locks up ,the EBC pads work better
when they get hot. Stock rear pads do not!

I find the composite leaf springs react quicker than steel so I think adjustable shocks would be a
benefit

Comments: The car is super stiff, with a very compliant ride. Very little body roll with excellent feedback at the steering wheel. The brakes are super strong and predictable. No rattles and squeaks. This cuda basically rides like a BMW 5 series with a sport package!!

I have a firm feel stage 3 steering box, PST sector shaft bearing, Tuff steering wheel, Hotchkis tubular upper control arms, boxed lower control arms, Poly bushings, Dr.Diff 1" rear leaf relocated brackets, custom bolstered seats with stock appearing skins, 3pt. seat belts, voltmeter, oil pressure and tach on standard cluster, battery relocated to the trunk

1. Best above improvement: Chassis bracing, hydroboost, upper control arm, torsion bars, sway bars, eaton trutrac, shocks, brakes, major motor, over drive computer controlled transmission, sound deadening, large wheels

2. Least effective above improvement ?

3.Future upgrades? Brighter modern headlights

4. Above car handles IMO on a 1-10 ( 10 best Viper, 1 stock): 8
