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!

Comments: NEEDS BETTER TIRES when autocrossing  :eek4:!!!!!
                  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!  :grinno:
                  I find the composite leaf springs react quicker than steel so I think adjustable shocks would be a   
                  benefit


1. Best above improvement: getting rid of bump steer

2. Least effective above improvement  Current tires

3.Future upgrades? Hydroboost brakes with 1 1/8" bore Master cylinder , adjustable shocks

4. Above car handles IMO on a 1-10 ( 10 best Viper, 1 stock):  7
