This does NOT look right
This does NOT look right So I noticed my car was bottoming out on rather small bumps. Thought I'd take the rear tires off to have a look to see whats goin on. Well I've seen my bump stops before, and I knew I had little suspension travel, but when I had a look tonight..... 
. The car has the Bilstein Ultra Performance Suspension System (SLP Eibach Springs) with koni shocks. Here's what it looks like:
And here's what my bumpstop looks like :
Why is it so rediculously low? Are my rear springs sagging? From the outside the car looks amazing how it sits, but damn, this is just rediculous. I bottom out over the smallest bumps, and this may be the reason I have been struggling with my 60' times (can you say no weight transfer
) So what does LS1tech recommend I do with my suspension? Obviously after riding on this for a while, I'm not too picky with the ride of the car. I like low, but I want something that will perform well at the 1/4 as well as handle great on the street. Some springs that would match my koni shocks would be great as well. I should also mention that these pictures were taken with 3/4 a tank of gas and a full stereo system (2 amps, capacitor, 12" infinity amp in custom box, all over the rear axle). No wonder I have been bottoming out so much 
. Thanks.

Edit: I put the car on jack stands and lowered the rear axle to get a better angle of my shocks. When the axle was at normal ride height, my yellow konis were all black. When I lowered the axle some yellow started showing again. Please tell me this is road grime and not 2 blown rear koni shocks

well you could grind some of the bump stops out for free to get more travel, or you could buy some air lift airbags for $50-$60 install them in the rear coils and pump it up at the track to get better weight transfer or around town, or you could get new springs.
I would guest that your coil are sagging.Because these are the parts that keep the stance of the car.
The shocks only absorb the bump and everything .Even with blown shock, your car would not be lowered.
Also it takes 5 minutes to take a shock off so if you still want to check them,take it off and check if there is any resistance when you try to compress them.
Stance = coil
Handling/damper/ = shock
My guess :the spring

Clean the shocks off and see if they are leaking.

Did i say bump stops? I said remove the spacers. the spacers are between the bump stop and the bump stop mount... They only came on the SS's.

Those shocks look blown. Do as always faster said, clean them off, drive around a while, and see if they're leaking. You shouldn't have any sort of road grime build up on the shocks like that, and it's not building up on anything else around the shocks.
That won't have any impact on your ride height, but it looks like you've got a couple problems there unfortunately.

The bump stop spacers are on there for a reason. The SS came wih larger wheels........hence they will bottom sooner than say the standard 16" wheel. The spacer prevents the larger wheel from hitting the inner fender under full compression situations........which right now you have all the time. How many hundreds of pounds does your stereo equipment weigh?

Also, I dont want to mess with the bump stops, they're there for a reason. I'd rather leave them alone and get some different springs. I was thinking DMS, how much will it raise my car up? Great replys, thanks.

Edit: forgot to mention, the car was lowered like this when I bought it, so I have not touched the suspension.

There's the culprit, the stereo equipment. Yes you need new springs. I have DMS rears, they do sit higher than most and have a nice spring rate. You can always look into picking up a set of stock rear springs and shocks for the time being for cheap then get a nice set of shocks and springs later, just a thought. I had a set with very low miles but pitched them... Trust me on the spacers, you can remove them and still never hit the inner fenders with stock SS rims and tires.
