Ground control weight jacks question
I just want to know,on the gc site it asked what type of shocks you are using (bilistein,KYB,etc.) do you have to use one of these brand shocks/struts to run the ground control set up? Or is it just reccomended? Basically can I use stock shocks with the ground control set up for now untill I order some bilisteins or something

Re: Ground control weight jacks question
/you won't HAVE to change your shocks & struts. But if you are looking to go for something like pure race, say 1000+ front/200+ rear then it would be strongly suggested that you do, that gain proper control of your suspension.
I have KYBs & GCWJ on my dd, but I'm also running just 650/150 springs. Easily controlled weights for the KYBs.

Re: Ground control weight jacks question
650/150 is not that far off the stock rates so I think you'd be fine. Mine are that low because I found my set used & what it came with. And despite having stiffer rear springs available (i have 3 sets of rear springs total), I haven't felt any need to get under my car & put them in.

Re: Ground control weight jacks question
Blackenedbird, I have already purchased Moog 5662/5665 springs for my car and was wondering if I could use these springs w/weight jacks, or do you need to get srings with them?
I had heard of these but until I actually saw them did not understand what they were or how they worked. Now, I think it's the greatest thing since sliced bread for suspenions.

Re: Ground control weight jacks question
In another tread that I read stated that the 5665 went from 107# to 110# with half coil cut. Really just depends on spring height needed for weight jacks, I guess. Thanks

Re: Ground control weight jacks question
Pretty much no change to the ride quality (stiffness is so slight, you wouldn't notice it) from the stock WS6 suspension springs. Mine aren't that drastically stiffer than stock (daily driver) & I don't exactly push it all that hard anyways on the street.

Re: Ground control weight jacks question
What spring rates would you recommend for a daily driver but I want it just a little bit stiffer then stock but still streetable dd

Re: Ground control weight jacks question
BlackenedBird, How did using these on the front affect the alinement? Do you need to have to change caster plates?
I checked out pics of your Bird vert, and like the ride height and the vette wheels on your car..it's very close to what I had in mind.
