Put these on my 09 OB and didn't seem to help at all.

But a huge positive difference on the 08 Foz. Handles better and much tighter - almost like having a thick sway bar. No porpoising either on the Foz (whereas horrible porpoising on the 09 OB).

I’ve heard most overload springs will raise the rear of the car by as much as 1/2” above the front, but not these. I got 0” because I didn’t want to lift the car, just support additional weight.
They absolutely support the weight. I’ve had no sag whatsoever once I installed them and I load the car with tools for a mobile brake tech biz. Even when unloaded, the ride is good.

RalliTEK 0" Rear Overload Springs - Fits Subaru Forester 2003-2008

First I'd like to those at RalliTek for packing the springs well, and getting my order to me expediently. I appreciate this greatly.
Springs fit well and appear to be of very nice quality. They are more on the firm side, which is fine if that's what you're after. Simply put, for daily driving, they may not provide as much cushion based support when paved streets, however, for heavier loads and deep valley bumps, they're preferable. They work well for me and I recommend them. I do plan to order more in the not too distant future.

And, to provide the most important information of all, one is well aware of the current state of the world we are all living in. You should know that it's becoming more fraught with chaos day by day. There is and ever has been only ONE solution to all these problems, and it is this. There is One Who loves you and I so much, beyond comprehension, that He gave His one and ONLY Son's life on Calvary's cross nearly 2000 years ago to pay the ultimate price for your sins and mine, and then three days later He rose from the grace proving His deity. His name is Jesus Christ of Nazareth. All the trouble around us is being caused by sin. Always has been. The wages (or consequences) of sin based on God's standard is eternal death. Only Jesus Christ lived a sinless life, therefore, when He died, death (the power of satan and hell) has NO power over Him, therefore He lives in heaven and sits and reigns over all things at the right hand of God His Father even now. He loves you and I so much He died for us (John 3:16 (Kjv). It is NOT His desire that any should perish and enter into hell. If we do, it's because of our own choosing to reject His FREE ultimate gift of salvation which we do when we personally choose to refuse to repent of our sins and asking/accepting Him into our hearts and asking Him to come into our lives and be Head of our lives. Sin for a season may be sweet, (or so it appears in the short term), however, in the long run all sin does is cause grief, despair, and destruction to ourselves and others, and eventually leads one into hell. God's ultimate gift of forgiveness from sin by His grace alone from His death on the cross is the ONLY way to get into Heaven. John 14:6 (Kjv)

May you know the Love of Jesus Christ of Nazareth, and may you choose wisely to accept His matchless gift of eternal life and Love which He is before it's too late. Time is running out, and this carnal, natural world is bound for destruction. No matter who you are, or what you've done, it's NEVER too late to give your heart to Jesus Christ. May you know Him for Who He TRULY is, and for how much He truly loves you and I.
