just curious.  i plan on getting those adjustable tension bars, and i konw they allow you to adjust caster which is good.  but how much caster can i run?  reason i ask is b/c i found an old ad for whiteline stuff and it had a little phrase under a set of bushings for the 180sx that said:  "there is no such thing as too much positive caster.  it improves response and handleing w/ no adverse effects on tyres."  so can anyone help me out?

the adverse effects are sluggish response and extra stress on the strut towers.  There is no need to add caster.  The 240sx has a factory setting of 6-7 degrees..  thats a lot.  one of the main reasons it's such a great drift car.  just cause something give you the ability to adjust it doesn't mean you have too..  The main reason I bought those kind of T/C rods was for the Pillowball Bushing..  adds a lot of steering feel.

just for reference, if you can get your hands on the may issue of Sport Compact Car, theres an article or two on what they call the "dave point". basically just their reasoning and explination of caster and its affects on steering and drifting. (At least thats what i got out of it)

Agreed - except about the drift thing. &nbsp;Quick turn/ nimbleness is valuable on any car in any driving. &nbsp;I just installed a set this weekend and it is amazing how much feel that bushing absorbs! &nbsp;It feels like I added about 8 lbs. of air to my tires (quicker, lighter feel, but much more road harshness - review/install coming soon).

As for how much...

I just installed a set and was planning on getting the car up on a rack this weekend. &nbsp;It didn't work out (plus I noticed that I should get new tie-rod ends, too). &nbsp;I am going to a place that does set ups for many of the local race cars, so I plan on taking some time and getting the best setting I can. &nbsp;Remind me in a few weeks and I'll let you know.
