SRT8 Suspension height question

[4life]

I did a quick search and did not find the answer, I think I saw .5" drop over standard C suspension somewhere is this correct.

Also does the SRT8 suspension have stiffer shocks or just the springs? The reason I ask is because I think my stock shocks are having a hard time dampening my heavy wheels when I hit bumps in the road.

Thanks in advance.

Yes, the SRT8 ground clearance is 5" and all other 300's have a 5.5" ground clearance. I am almost certain the SRT8 springs and chocks are both stiffer than the 300C 5.7, but I don't have any facts to support this.

The SRT8's front struts are a stiffer strut.

The rears are a self-leveling Nivomatt shock that is stiffer then the standard C shock. However if you plan on lowering the car past the SRT coil height it will pick it back up to that same height.

Thanks for all the replys, I think that answers my questions. Im going to give an SRT8 suspension a try to see if it helps dampen the bump steer from my 22" wheels.

Just FYI, "bump steer" has nothing to do with wheels. Bump steer is a condition caused by misalignment of the control arms and the tie rods, typically brought about by a spring drop.



The only thing that can change bump steer is to change the relationship between the tie rods and control arms, typically done by raising or lowering the steering rack or adding spacers at the knuckle end of the tie rod.

If you are feeling a bump through the steering wheel as a result of heavier wheels, it is a damping issue, so stiffer shocks is the right solution, but it's not "bump steer."

FWIW, I feel significant bump steer on my 07 CSRT8.

Not to split hairs since it sounds like you know what you are talking about, wouldnt what is happening to me be exactly what you descibed as bump steer? I hit rough roads, my wheel bounces up farther because of the heavier wheels and the springs and shock cant dampen it enough so the end result is bump steer.

It's me that splitting hairs. I posted the correction mostly so people would not find this thread when they searched for "bump steer" and be confused that shocks could fix it.

On bump steer, the tie rod misalignment causes the steering knuckle to move in or out on suspension articulation. This causes the car to move to one side or the other on a single wheel bump. Most street cars have a bit of toe-in bump steer designed into the suspension to give a feeling of stability on hard braking.



To measure bump steer, you remove the wheel, shock, and spring, and move the suspension through its travel. The amount of toe change (i.e., steering) is measured, and if possible, corrected.

So bump steer is fixed in the suspension, and is independent of wheel, shock, or spring.

I would describe what you are feeling (as I understand it) as simple loss of contact with the road from underdamping.
