the vintage Trans Am cars suspensions were level so they would handle better. with that in mind, you can go with tires that are different widths, but they need to be the same height. any improvements you are trying to get are going to be negated with those tires. on average, those tires (depending on rim size) are about an inch different in height, and that is a lot for tires

your car would handle a lot better, for a lot cheaper thanthe direction you are going in,by just increasing your front tire size. a front tire that small is going to want to roll anytime you put any slight pressure on it by going hard into a corner.

when it comes to handling, a way you can get yourself into trouble, and into an unbalanced set-up is todo a big suspension change to try to improve handling, without first taking care of the smaller and cheaper problems first

just trying to make you think about a few things here first, before you go and spend a bunch of cash on something that isn't really going to help you as much as you think it's going to help

 

I cant stress enought that you dont want drop spindles.. You will have problems. One with that type of set up u will hit ur rims with ur tir rob. Then ur sterring will be off.

 

all i got to say is Hotchkis TVS!!! i have it on my 67 camaro and dont have any problemswith it,it was'nt that difficult to put in, you get great handling, you get a lower car and no need to worry about tires rubbing trust, the only thing i can say is that its stiff and thats agood thing yes but going over bumps and railroad track well lets say it aint no caddy haha
