Does anyone know the difference in the springs, front and rear, between 9c1, impala, and stock caprice. I would like to find out the difference in the heights and thickness. I have a 94 Caprice with Impala springs and want to raise the front a bit. Just a couple of more things, what is the approximate life expectancy of each; do heavy duty stocks last as long as the already thick 9c1? The last thing I would like to know are good shock combinations for the springs; which combos will give me the best balance between shock and spring. I run 265/50/15 on front with worn out shocks, and 295/50/15 on rear with air shocks; I'm trying to get all this info so when I go under to make changes and fixes, I do it right the first time. Thanx

I think the "search" function could be your friend ;)

Spring heights have been discussed A LOT here... so you should find plenty to read.

Good luck and post pix when you get it where you like it.

Funkyvibes, I had 20x9 and 235s all the way around on the car with SS springs before I made this current change. It looks nice but you will probaly get a little rubbing in the front if you turn the wheel all the way. I didn't like that, that's why I changed.

one more thing. you don't want to cut the springs, this is never a good idea. plus our springs are not even all the way up, so if you cut either end the spring won't fit right again. the spring change should give you what you want.

I put 15x8 in the front with 265/50s, 15x10 in the rear with 295/50s, and I changed the offset with the change of rim style. The car has always had the impala springs on it, so it has always sat low, this is why I'm trying to see what difference I could make with a different spring; 265/50 on 15s with impala springs sit low. But when it had the 20s it sat at about normal impala height. As long the diameter of your tires are around 27 in. you will be cool. If you run 235s on a 20x9 then you are at 26.48 diameters; which is perfect.

ok so it sounds like the impalla springs will lower the car without making a cut right.
