Front end improvements

[S60UT]

I understand the P2 S60 is known for having a soft front end. But my S60 feels so soft compared to my BMW E46 touring. I have replaced lower control arms, sway bar end links and installed the IPD sub frame inserts. New struts and associated hardware to be purchased next. What have you guys done to improve the stiffness of your front ends. The steering seems so soft and sensitive like it wants to dart off the road. Is there any steering lash adjustments on these cars ?

Note everything you do to tighten up the steering on these will cumulatively impact ride quality - but if you want it more like the BMW...

Control arm bushes: forward/front bush replace the OE with greased polyurethane type. The OE has a bit of controlled 'lash' or play built in like the subframe bushes you've already addressed.

Tires: typically these cars are equipped with squishy soft tires for ride quality. Use a performance stiff sidewall tire. I installed Pirelli P7 LRR XL. I am also a fan of Michelin--they also make tires well suited for daily drivers with a great balance between ride quality and handling.

Now I didn't ask which brand control arms you installed. Are you getting loud clunks and wild handling characteristics over manhole covers/potholes etc? Some aftermarket LCAs and their bushes are no good: the rear bush rubber isn't formulated to control LCA movement with the correct mechanical properties. Because of the geometry these cars are very touchy about this. The rear LCA bush can end up with an up/down 'float' and bangs against the subframe mount. This also introduces undesirable play into the system under all conditions. Upon inspection the bush looks fine, but it's too 'stretchy' while driving. If you're not getting noise then the LCAs you used are probably ok in this regard.
