Plum-72: If you're only looking for slight improvements, then any good shock will help.. you pay for what you get. I'd rather get double-adjustable shocks (consider the Vikings as they are less expensive and also originated from the QA1 designs).

Then, for better steering response, the upper control arms should be replaced by aftermarket types (QA1, Firm Feel, others) as they all offer the additional extra positive caster that the factory OE design never did offer. Or else, simply install the Moog Problem Solver offset UCA bushings (install them reversed)... that will get you more positive caster and some negative camber. but, as long as you'd have the UCAs out already, may as well just install new aftermarket types. the various adjustable UCAs are great for fine-tuning the front end, where as the non-adjustable only give you a pre-designed amount of adjustment (still much better than stock).

The QA1 struts and sleeves are your option.

Also, consider larger torsion bars to help reduce excessive lift and dive... you'll be amazed at the difference slight increases make. The increased stiffness of the TBs are truly not very harsh. A 1.12 is a good TB bar for great improvement.

Question: What is your car, engine, etc?
