As I explained in the other, prior message ("Part 1: ...antisway bars...", second message down below this one), this is to set up a '93 240 (for my daughter, who's a fast highway driver) that's as safe handling as possible (see other, for details).

Another improvement I'm thinking of adding is IPD's Chassis Braces (and this would be in addition to IPD's f&r antisway bars.

I know that these braces are supposed to sharpen the steering response -- but what else (especially negatives) would I (or she) notice, especially on real roads (city potholes, frost heaves) as well as smooth highway?

Also, as with the antisway bars, IPD sells seemingly two versions of their chassis braces, too. One is CU2485 (upper strut brace and lower brace, as a set, "Cherry Turbo"), and the other is CU1240 plus CU1350 (upper chassis brace plus lower tie bars). These are not quite the same -- any advice on distinguishing between their purposes and their effects?

As always, thanks very much all of you for your advice.
