who makes the stiffest lowest spring

[andrewro]

What are your tire and wheel sizes and offset for a car that is dropped 2" or so without coilovers?

[TMK-001]

Get coilovers for your Colorado and put your H&R's and Billy's on the red rocket!! Win, win!

I drove about 5,000 VERY hard miles without any reinforcement at the rear using coilovers and nothing burst through. My back end was about as saggy as Pavarotti's, but that's another story.

The rear shock towers should be reinforced if you add coilovers in back. This was actually talked about in length here and if you use the search you could probably find the thread on it. With the increased stiffness of the coilover, you end up with more stress/load being put on the shock towers themselves. With the added stress, the 'nipple' part of the shock tower can break off at the weld. The best bet would be to weld, not bolt, in a brace between the two towers, or extend your roll cage into the trunk and weld it to the shock tower nipples.

Don't get me wrong Jeremy, I totally agree and have welded in reinforcement, all I was saying was that I was kind of surprised that after 5k hard driven miles the tops of my shock towers looked totally straight, and certainly didn't burst through.

What exactly do you mean about reversing the rear subframe mounts? I am just not quite picturing them reversed. Do you have a picture by chance? Thanks,

Take them off, turn then 180 degrees, re-attach. It moves the whole subframe up a cm or so.

cut the "progressive" section off a set of H&Rs,,, the resulting spring should be mighty stiff and prolly a good 3-4" shorter than stock!!

NASCAR my friends. Or actually any circle race track store will have springs that fit our car. Just find ones in 5" diameter and any length and rate you need. here is one of the sources i use. http://www.pitstopusa.com/

I still don;t know the differnce between the front and rear spring, and they help support was no help.

I run 5x8.5 in the rear.
