Rear P springs

[k98dave]

I would like to get rid of some of that tail high stance. So would running P springs with adj panhard bar and stock LCA's be ok?

If you went to the track I think you would find it a but tail happy. I found the P springs terrible in the rear if you do not have adjustable LCA to take care of the rear axle. With out it the car was like a crab scuttling sideways!

I think it's okay if you use brackets that will fit the stock LCAs. Lowering the car more than 1" or so with *any* spring without using relocation brackets is a bad idea IMO.

OK, I just bought the P springs, FRRP LCA's & brackets, & adj Panhard bar that Yellow Boss's had listed for sale so that should work out. Still need to get bump stop set. I see GT 500 front upper spring perches listed on some sights, are these worthwhile or are they the same as Boss perches?

I ran this exact set up with P springs in the back and all stock front for a few months. No issues.
Be sure to install the lowering brackets.
A big improvement in height and handling

They will not fit Boss or other '11+ struts other than GT500s. They also work with older style '05 to '10 struts.

I ran the P rears only for a few months.
Actually worked very well.
