Hotchkis or QA1 all inclusive kits - which one?

@72bluNblu broke it down succinctly with his question of what you want to do with the car.

when you're doing the front suspension you have to think of it like a system; everything has to work together and all the components have to complement each other in order for it to work correctly. you can have all the johnny kick *** stuff, but if none of it works together then you have a car that sucks to drive.

the second consideration is selection of items. if you want big aftermarket disc brakes you'll need big aftermarket wheels. big aftermarket wheels may not come in the style you like, or may necessitate a compromise in size to fit the body or your wallet. the same with something like control arms- you may not need adjustable tubular uppers, but you may want them. the bigger you go with t-bars the better the shocks need to be.

so even something that seems as trivial as: i want 13" brakes means considering other elements in the whole system.

if you've already got 73~76 disc brakes, and the lower control arms have tabs for a sway bar? that's the good bones for a decent set up. you can upgrade the master cylinder, upgrade the rotors, run aggressive pads, and fit a larger sway bar, knock on some larger t-bars, get some good shocks and then refresh the wear components (bushings mainly) with poly or upgraded pieces. adjustable strut rods and plating the LCA's are nice options, but i wouldn't call them necessary for a car that isn't expected to autocross.

in other other words there's a lot you can do with what you have and there's more that can always be done later. but if you start with a good foundation then those upgrades are easier down the line.

having an idea of what you want ride wise, and how you want it to look is a important first step. from there, you can make better informed decisions on specific components and where you want to spend that hard earned money and what you can reuse to save some of that dough.
