Hotchkis or QA1 all inclusive kits - which one?
you take the factory torsion bar suspension a LONG way for about 1/2 the cost of anything aftermarket and get damn near the same results.
carefully selected rebuild pieces and judicious acquisition of aftermarket components can make a really nice handling and driving car.
it really comes down to what type of driving you plan on doing and how much bling you want.
what are you starting with? do you have stock disc brakes and a sway bar already? do you want rear disc brakes?
