Lets say you have a modified with some 94 shocks on the back and you change the right rear to a 93 and every condition is the same as ran with the 94. What will it do to the car handling?

Basically, the car will roll onto the RR a little quicker entering. All a shock is, is a timing devise. It won't affect how much it rolls, but rather how soon it starts rolling.

It would help to plant the RR sooner and tighten entry.

okay,im sure im wrong,this is prolly my 'fat body car' handling im thinking and not mod,but along with tighten on entry,with the 93 on rr,wouldnt that wanna tend to loosen on exit,or would other factors over come that.

The softer shock will load the RR quicker on entry but will also unload it quicker on exit. It will let the car roll quicker both ways, on extension and compression.

what would it do if you put a 3 in 5 out on the rr?

That would help the car "hold" its roll longer. I would THINK that might help LR bite on corner exit because it keeps the LR on the bars.........any other ideas?

do you think this shock 3 in 5 out shock on the rr would how to fix a tight off problem.

It might help some depending on how severe it is. Shocks will fine tune a chassis but wont fix major problems.

what do you guys think about running a 5 lr and the 3 in 5 out on the rr........what will this make the car do as far as getting on the bars.

The 5 in/out LR will prob slow the car down a little getting on the bars, because the shock is resisting the seperation of the frame and the axle. How much I dont know, I would think you woudl have to go pretty stiff on the LR before you noticed it but again I dont know.

It all depends on the driver and how sensitive the car's chassis is to changes. If the chassis is very sensitive then the car will be slower getting on the bars. I might would try the 94 LR and 93-5 RR.

My understanding is this: say you have two 75 shocks on the front, The weight will be equally distributed to both rear tires. Now if you put a 74 LF and 75 RF the RR will get the weight quicker. Also the opposite is true. But thats also the front. The front doesn't use a solid axle. So on the rear if you soften the RR the car will roll quicker and allow the LR to extend quicker therefore getting on the bars quicker.

Anyone else have input on my theory?

Softer RR shock will let it roll quicker,but
a heavyer rebound softer comp. shock on LR will keep weight on LR longer,tighing entry and allowing car to turn better. More LR bar angle
will get it on bars faster.

I would think that a heavier COMP and weaker REB on the LR would help the turn exit more. The only thing about adding more bar angle is that if you are dealing with shocks then you are FINE tuning. A bar change would probably be too much, but yeah more angle gets it on the bars quicker. Also more bar angle equals more roll steer therefore if your just fine-tuning the chassis then you've thrown it all out the window. Whereas a shock change will be a finer adjustment.
