Lowering Issues
I got my corvette lowered with a set of lowering bolts. On my passenger side in the rear there is grease that is getting all over my rims while I am driving. That is also the only corner that is having issued bottoming out and the tire is eating up my inner fender. Before I take it back to the shop that did it. What could the issue be? Anyone else run into this problem? My driver side in the rear is just as low, it does not bottom out/scrape in the inner fender, and has no grease at all on the rims. I hope I explained this correctly. Any help would be greatly appreciated.

Because you haven't said anything about your brakes, I'm going to assume that the brakes are still working fine.. because another reason you may have oil on the rim is because the brake caliper cylinders may be leaking or you have a loose or broken brake line.
I would take a close look at the shock and see if you can tell if the oil is coming from there.

I live right up the road from ya in Macon. If you need some help trying to figure it out, I have a garage with all the tools we need. I have lowered all 3 of my C6's and can help you find out the problem. Let me know if you need a hand.......don't have a lift but gotta air compressor and all the tools we will need. PM me if ya need a hand! If your shock is leaking, that's an easy part to remove/replace.

Sounds like to me you may have had a shock go out. Is there grease on the shock also. I just replaced the shocks on a friends car that was bottoming out on one side. When we took the old shock off it had grease on it. If you push down on the passengers rear side of the car... Dose it feel like it has less tension then the other side?

It's not oil. If I'm not mistaken when I was cleaning off the rims yesterday it was thick and darker green. Don't quote me exactly on the color though.

Perhaps the shop saw those lube fittings and decided to shoot some new grease in there for you.
It could definitely ooze out and get on your wheels.

Since on the C6 your engine/transmission and diffential are all mounted on the same frame, lowering shouldn't effect drive line constant velocity joint life, but those connecting the differential to the rear drive wheels through the interconecting half shafts will likely experience shorter life as will the rear wheel bearings and seals. Front and rear suspension travel will also be reduced as well as ground clearance over speed bumps, or such things as elevated railroad roadways adjacent automotive roadways, underground parking garage approch and departure angles, etc., etc. The Corvette as it comes from the factory is a low as the engineers thought practicle. These automotive engineers take into account civil engineering standards, test track results, etc. Anytime you think you know more than these engineers and alter the car's ride height you are setting yourself up for problems.

May not be the fun answer but it is the real one.

Thanks everyone. I'll be flying back to Afghan tomorrow so the vette is locked up in my parent's garage until my next break in April. But I'll be sure to keep everyone updated on what it is once I get back. Thanks again
