Roush My 88 rides like Crap!! Fix plan!

I have an AJE and they have just as many issues as the rest of them. There is no question that the MM and Griggs are much stronger and reliable, no point in debating the KB since they are gone.
If this car is a daily driver, i'd seriously reconsider using it, Aftermarket K's come apart at the seams (literally) from daily use on beat up roads.
If it's a pleasure car, you should be ok.
I've had a chance to pretty much compare all k members at one time or another, and unless it's an absolutely necessary part for a specific reason, I wouldn't use one.
I'm not trying to beat a dead horse here just to be right, i'd just hate to see what happens to your beloved saleen if the k member breaks, and trust me, it happens.
The stock piece is nearly indestructable, not the same can be said for the aftermarket ones.

I hear you about the geometry issue, that's why i say if you can't go all out with this mod, don't do it at all.

I didn't want one, but my application requires it.
And i don't think it comes with spring perches, you must purchase them seperately.

3000 miles is nothing, by your concern about the ride quality i was thinking you were driving alot more than that, possibly daily.
Mine didn't come with the perches, they were like an extra $50.

Here's a list of the different spring rates by manufacturer. It will help give you a reference point when comparing springs. 1987 thru 1989 Saleen's (excluding SSC's) had specific rate springs with a front rating of 650 lbs. and rear rating of 300 lbs.
