Question About Transplanting R Sedan Springs Into T5 Wagon


USMC850T

Recommended Posts

I am looking to buy a set of R sedan springs for my 96 850 T-5 wagon and I want to know if it will work. I am also planning on new F/R sway bars from IPD in the future. The ultimate goal is to get a much stiffer ride, ie significantly reduced body roll and not having the front corner of the car drop under hard turning.

PS i did use the search feature, but I didn't see a black and white yes/ no answer and I appreciate any help anyone can give.

Thanks,

Jeff

R springs are good but if you want to reduce roll in the wagon you're going to have to spend a bit more. You'll get a LOT more responsiveness with the R springs but body roll reduction isn't as good as you'd think it was based on how it handles. I'd make sure I considered all my other options thoroughly before going to R springs.

You can do it, but I think there's enough extra weight in the rear end of a wagon to make a difference. I like the R springs. You might want to go with bilstein rear springs made for the wagon or FCP sells a heavy duty rear spring for the wagon for like $41/per. Sway bar links and sway bars are going to make the difference.

Are you active duty?

Be careful with this. You might want to try and get info on each of the springs' specs so that you could run them thru the calculation to see what the comparative rates are. That is, wire diameter, number of coils. The other variables are the same, such as coil diameter, because you are just going between sedan and wagon.

The reason I say all of this is when I pulled the stock springs from my '96 R sedan I was going to use them in my base '98 V70 but I found that the wagon's stock springs had a heavier wire diameter with an equal number of coils (if I recall correctly now). In any case, when I ran the spring specs thru a rate calculator the wagons spring rates (especially in the back) were quite a bit different (stiffer) than the standard R springs.

Good luck,

I am OCS right now, and will go active duty in 07 from TBS (the basic school - think infantry skills, close quarter tactics) straight into flight training. 10 weeks at quantico this summer for officer school and 1 year of college left before I commission as a 2lt.

Thanks for everyone's advice on the issue. I am looking at getting the springs pretty cheap and will most likely start with R's + IPD sway bars. If i need more performance I will upgrade to the Blisteins.

Ok so this means that the spring compresses slower under a given force than the wagon spring would, meaning more stiffness?

Lower rate means that it will require less weight to depress the spring a given distance. Thus a 150 lb spring will require 150 lbs to depress the spring one inch versus a 220 lb spring which, obviously, will require 220 lbs to do the same thing.

Since a wagon's and sedan's curb weight is similiar, a given spring would probably depress a similar amount at static weight. Where you would have the issue is when you would load up the ole family truckster. Because you can get more in a wagon, it would squat x amount based on how much weight you could get in the back. That's why Volvo uses a heavier rear spring on the wagons and to be honest I'm not sure about the front. Once I knew my R springs would not work on the back I wasn't going to screw around just to drop the front.

So R sedan springs will not transplant to t5 wagons?

Dimensionally, they will fit find. I just think that they will be too soft if you ever plan on hauling anything in the back of the wagon.

Actually, they are not hard to change in the back so you could always give it a go but....the proper lowering springs are actually the best option. And you are only looking at $200-250 for the full set (assuming that you are going to also pay for shocks regardless of how you go).

Come on; once you graduate from OCS you'll have the money to do it right anyway. Surely they are paying better than the $20K per year that they were 30 years ago.
