I Need Your Suspension Advice , Can You Help ??

[Paddlee30]

Thanks for viewing and for your advice , here is where im at with my suspension :

I have ordered the Ground Control Kit with the single adjustable Koni's , front spring rate 440 & rear is 650 . I now need to order a Sway Bar Kit and am having trouble deciding on what kit to get.
The main use for my car will be " Very Swift Mountain Runs" and occasional Auto Cross. Im NOT concerned with a harsh ride as this will not be my DD. I want to corner balance the car and know that a SB kit with adjustable end links is needed. As you guys know there are several SB kits out there in various sizes, please chime in with your opinion and why. Thanks in advance !!

Also on a side note , how will front and rear strut tower bars affect the handling after choosing a sway bar kit ?? I am planning on a S54 swap in the future . :thank you

most of my friend have the IE stuff and love it. but both are good products.
while i love and hate uuc for different reason, theirs seem to have more failures and if it were for me id not get their bars.
