I have bilsten shocks and rsr springs in my car along with f&r strut bars, it handled good but didnt turn in as good as I liked.
The other week I fitted whiteline swaybars adjustable, 24mm front 22mm rear i think, with the bushes for the lower control arm and the adjustable ones to reduce the neg on the back, I also changed the from caster rod bushes to give more caster and fitted the rings to take the complience out off the diff. Doing this made the car heeps better, it is a bit stiffer but just turns in so much better and the rear grips much better and if it does step out it comes back much quicker.
On the cruise the other week I was doing a good job of keeping up with a john in his 34 gtr through the hills with pretty adverage tyres.
If you want any whiteline gear I can get it cheap, the f&r swaybars were about 250 new.
